I would like to add onDblClick event to codemirror 2. I found that onCursorActivity does not deliverer the event so there is no way for me from this method to filter the events.
How can I implement onDbClick event on Codemirror ?
Thanks in advance.
You can call on method on object returned by CodeMirror:
var cm = CodeMirror.fromTextArea(document.querySelector('textarea'));
cm.on('dblclick', function() {
alert('You double click the editor');
});
You can find the list of all available events in documentation.
Register a handler on the element returned by the getWrapperElement() method. Unless you want to not just detect double-clicks, but also prevent the default (select word under mouse cursor) from occurring... in that case I guess some modification of the core code is needed.
http://jsfiddle.net/yusafkhaliq/NZF53/1/
Since codemirror renders inside the element specified you can add an ondblclick event to the element, like below the highlighter renders without line numbers once double clicked that specific elements will display line numbers
var codeelems = document.getElementsByClassName("code");
for (i = 0; i < codeelems.length; i++) {
(function ($this) {
var value = $this.innerHTML;
$this.innerHTML = "";
var editor = CodeMirror($this, {
value: value,
mode: "text/javascript",
lineNumbers: false
});
$this.ondblclick = function () {
editor.setOption("lineNumbers", true);
}
})(codeelems[i]);
}

I have an extension that grabs the open file's text and alters it. Once the text is altered, how do I put it back into the file that is displayed in VSCode?
// this method is called when your extension is activated
// your extension is activated the very first time the command is executed
export function activate(context: vscode.ExtensionContext) {
// Use the console to output diagnostic information (console.log) and errors (console.error)
// This line of code will only be executed once when your extension is activated
console.log('Congratulations, your extension "myExtension" is now active!');
console.log(process.versions);
// The command has been defined in the package.json file
// Now provide the implementation of the command with registerCommand
// The commandId parameter must match the command field in package.json
let disposable = vscode.commands.registerCommand('extension.myExtension', () => {
// The code you place here will be executed every time your command is executed
let activeEditor = vscode.window.activeTextEditor;
if (!activeEditor) {
return;
}
let text = activeEditor.document.getText();
getAsyncApi(text).then((textToInsertIntoDoc) => {
let finaldoc = insertTextIntoDoc(text, textToInsertIntoDoc);
// not what I want - just used to see new text
vscode.window.showInformationMessage(textToInsertIntoDoc);
});
});
context.subscriptions.push(disposable);
}
The API you can use here is TextEditor.edit, whose definition is
edit(callback: (editBuilder: TextEditorEdit) => void, options?: { undoStopBefore: boolean; undoStopAfter: boolean; }): Thenable<boolean>;
It asks for a callback as the first parameter and in the callback, you can make edits to the document by visiting editBuilder.
I put a sample extension in https://github.com/Microsoft/vscode-extension-samples/tree/master/document-editing-sample which reverses the content in current selection, which is basically a simple use TextEditor.edit.
This is a revision of the main function in Rebornix's extension sample (included with the set of Microsoft extension samples) that handles the selection issues you raised. It reverses the content of the selection(s) (leaving the selections) or if a selection is empty it will reverse the word under the cursor at that selection without leaving anything selected. It often makes sense to leave a selection, but you can add code to remove selection.
let disposable = vscode.commands.registerCommand('extension.reverseWord', function () {
// Get the active text editor
const editor = vscode.window.activeTextEditor;
if (editor) {
const document = editor.document;
editor.edit(editBuilder => {
editor.selections.forEach(sel => {
const range = sel.isEmpty ? document.getWordRangeAtPosition(sel.start) || sel : sel;
let word = document.getText(range);
let reversed = word.split('').reverse().join('');
editBuilder.replace(range, reversed);
})
}) // apply the (accumulated) replacement(s) (if multiple cursors/selections)
}
});
Admittedly, while I could remove a single selection by setting .selection to a new empty selection that doesn't seem to work with .selections[i]. But you can make multiple changes without having selections in the first place.
What you don't want to do is make a selection through code just to alter text through code. Users make selections, you don't (unless the end purpose of the function is to make a selection).
I came to this question looking for a way to apply a textEdit[] array (which is normally returned by a provideDocumentRangeFormattingEdits callback function). If you build changes in the array you can apply them to your document in your own function:
const { activeTextEditor } = vscode.window;
if (activeTextEditor) {
const { document } = activeTextEditor;
if (document) {
/*
build your textEdits similarly to the above with insert, delete, replace
but not within an editBuilder arrow function
const textEdits: vscode.TextEdit[] = [];
textEdits.push(vscode.TextEdit.replace(...));
textEdits.push(vscode.TextEdit.insert(...));
*/
const workEdits = new vscode.WorkspaceEdit();
workEdits.set(document.uri, textEdits); // give the edits
vscode.workspace.applyEdit(workEdits); // apply the edits
}
}
So that's another way to apply edits to a document. Even though I got the editBuilder sample to work correctly without selecting text, I have had problems with selections in other cases. WorkspaceEdit doesn't select the changes.
Here is the code snippet that will solve your issue :
activeEditor.edit((selectedText) => {
selectedText.replace(activeEditor.selection, newText);
})
Due to the issues I commented about in the above answer, I ended up writing a quick function that does multi-cursor friendly insert, and if the selection was empty, then it does not leave the inserted text selected afterwards (i.e. it has the same intuitive behavior as if you had pressed CTRL + V, or typed text on the keyboard, etc.)
Invoking it is simple:
// x is the cursor index, it can be safely ignored if you don't need it.
InsertText(x => 'Hello World');
Implementation:
function InsertText(getText: (i:number) => string, i: number = 0, wasEmpty: boolean = false) {
let activeEditor = vscode.window.activeTextEditor;
if (!activeEditor) { return; }
let sels = activeEditor.selections;
if (i > 0 && wasEmpty)
{
sels[i - 1] = new vscode.Selection(sels[i - 1].end, sels[i - 1].end);
activeEditor.selections = sels; // required or the selection updates will be ignored! 😱
}
if (i < 0 || i >= sels.length) { return; }
let isEmpty = sels[i].isEmpty;
activeEditor.edit(edit => edit.replace(sels[i], getText(i))).then(x => {
InsertText(getText, i + 1, isEmpty);
});
}
let strContent = "hello world";
const edit = new vscode.WorkspaceEdit();
edit.insert(YOUR_URI, new vscode.Position(0, 0), strContent);
let success = await vscode.workspace.applyEdit(edit);
I've a popover component and I added a multi-select list inside of it. I would like to set checked property to true for all items in case of the first item of list is selected. But selectionChange event works for every item's selection event. So, index value of the for loop always starts with zero. What should I do in this situation? Thanks for your suggestions.
Here is my part of a code and screenshot of image;
image url
new sap.m.List('statusTypesList', {
mode: 'MultiSelect',
selectedKeys: " ,1,2,3",
includeItemInSelection: true,
selectionChange: function(oEvent) {
var keyValues = "";
var itemArray = oEvent.oSource.getItems();
if(itemArray[0].getSelected()==true){
for (var i = 0; i < itemArray.length; i++) {
oEvent.oSource.setSelectedItem(itemArray[i], true, true);
}
}
}
})
Check if the item that fired the event is the first one in your list. Something like this:
function(oEvent) {
var changedItem = oEvent.getParameter('listItem');
if(changedItem isTheFirstItem){
//Where 'isTheFirstItem' is the condition you define to identify your first item
var keyValues = "";
var itemArray = oEvent.getSource().getItems();
if(itemArray[0].getSelected()==true){
for (var i = 0; i < itemArray.length; i++) {
oEvent.getSource().setSelectedItem(itemArray[i], true, true);
}
}
}
Define the condition you want in the if(changedItem isTheFirstItem) statement
Try this condition, maybe it works: if(changedItem === oEvent.getSource().getItems()[0])
If not, just build your own condition to check if it is the first one or not
NOTE: User getSource() to get the source from the event. It is always better than accessing the object directly
The click seems to fire the event and set the cookies but pressing enter to submit doesn't set the cookies and instead the page redirects without the cookies.
function locationAuto() {
$('.search-location').focus(function () {
autocomplete = new google.maps.places.Autocomplete(this);
searchbox = this;
google.maps.event.addListener(autocomplete, 'place_changed', function () {
var thisplace = autocomplete.getPlace();
if (thisplace.geometry.location != null) {
$.cookie.raw = true;
$.cookie('location', searchbox.value, { expires: 1 });
$.cookie('geo', thisplace.geometry.location, { expires: 1 });
}
});
});
The .search-location is a class on multiple textboxes.
There is a submit button that takes the values from the cookies and redirects (server side)
Adapted from Jonathan Caulfield's answer:
$('.search-location').keypress(function(e) {
if (e.which == 13) {
google.maps.event.trigger(autocomplete, 'place_changed');
return false;
}
});
I've encountered this problem as well, and came up with a good solution. In my website I wanted to save the autocomplete.getPlace().formatted_address in a hidden input prior to submission. This worked as expected when clicking the form's submit button, but not when pressing the Enter key on the selection in the autocomplete's dropdown menu. My solution was as follows:
$(document).ready(function() {
// Empty the value on page load
$("#formattedAddress").val("");
// variable to indicate whether or not enter has been pressed on the input
var enterPressedInForm = false;
var input = document.getElementById("inputName");
var options = {
componentRestrictions: {country: 'uk'}
};
autocomplete = new google.maps.places.Autocomplete(input, options);
$("#formName").submit(function(e) {
// Only submit the form if information has been stored in our hidden input
return $("#formattedAddress").val().length > 0;
});
$("#inputName").bind("keypress", function(e) {
if(e.keyCode == 13) {
// Note that simply triggering the 'place_changed' event in here would not suffice, as this would just create an object with the name as typed in the input field, and no other information, as that has still not been retrieved at this point.
// We change this variable to indicate that enter has been pressed in our input field
enterPressedInForm = true;
}
});
// This event seems to fire twice when pressing enter on a search result. The first time getPlace() is undefined, and the next time it has the data. This is why the following logic has been added.
google.maps.event.addListener(autocomplete, 'place_changed', function () {
// If getPlace() is not undefined (so if it exists), store the formatted_address (or whatever data is relevant to you) in the hidden input.
if(autocomplete.getPlace() !== undefined) {
$("#formattedAddress").val(autocomplete.getPlace().formatted_address);
}
// If enter has been pressed, submit the form.
if(enterPressedInForm) {
$("#formName").submit();
}
});
});
This solution seems to work well.
Both of the above responses are good answers for the general question of firing a question when the user presses "enter." However - I ran into a more specific problem when using Google Places Autocomplete, which might have been part of the OP's problem. For the place_changed event to do anything useful, the user needs to have selected one of the autocomplete options. If you just trigger 'place_changed', the if () block is skipped and the cookie isn't set.
There's a very good answer to the second part of the question here:
https://stackoverflow.com/a/11703018/1314762
NOTE: amirnissim's answer, not the chosen answer, is the one to use for reasons you'll run into if you have more than one autocomplete input on the same page.
Maybe not the most user friendly solution but you could use JQuery to disable the enter key press.
Something like this...
$('.search-location').keypress(function(e) {
if (e.which == 13) {
return false;
}
});
I have the feature ID, I can grab the marker layer on GeoRSS loadend, but I'm still not sure how to cause the popup to appear programmatically.
I'll create the popup on demand if that's necessary, but it seems as though I should be able to get the id of the marker as drawn on the map and call some event on that. I've tried using jQuery and calling the $(marker-id).click() event on the map elements, but that doesn't seem to be working. What am I missing?
Since I was asked for code, and since I presumed it to be boilerplate, here's where I am so far:
map = new OpenLayers.Map('myMap');
map.addLayer(new OpenLayers.Layer.OSM());
map.addLayer(new OpenLayers.Layer.GeoRSS(name,url));
//I've done some stuff as well in re: projections and centering and
//setting extents, but those really don't pertain to this question.
Elsewhere I've done a bit of jQuery templating and built me a nice list of all the points that are being shown on the map. I know how to do a callback from the layer loadend and get the layer object, I know how to retrieve my layer out of the map manually, I know how to iter over the layers collection and find my layer. So I can grab any of those details about the popup, but I still don't know how to go about using the built-in methods of the DOM or of this API to make it as easy as element.click() which is what I would prefer to do.
You don't have to click the feature to open a popup.
First you need a reference to the feature from the feature id. I would do that in the loadend event of the GeoRSS layer, using the markers property on the layer.
Assuming you have a reference to your feature, I would write a method which handles the automatic popup:
var popups = {}; // to be able to handle them later
function addPopup(feature) {
var text = getHtmlContent(feature); // handle the content in a separate function.
var popupId = evt.xy.x + "," + evt.xy.y;
var popup = popups[popupId];
if (!popup || !popup.map) {
popup = new OpenLayers.Popup.Anchored(
popupId,
feature.lonlat,
null,
" ",
null,
true,
function(evt) {
delete popups[this.id];
this.hide();
OpenLayers.Event.stop(evt);
}
);
popup.autoSize = true;
popup.useInlineStyles = false;
popups[popupId] = popup;
feature.layer.map.addPopup(popup, true);
}
popup.setContentHTML(popup.contentHTML + text);
popup.show();
}
fwiw I finally came back to this and did something entirely different, but his answer was a good one.
//I have a list of boxes that contain the information on the map (think google maps)
$('.paginatedItem').live('mouseenter', onFeatureSelected).live('mouseleave',onFeatureUnselected);
function onFeatureSelected(event) {
// I stuff the lookup attribute (I'm lazy) into a global
// a global, because there can be only one
hoveredItem = $(this).attr('lookup');
/* Do something here to indicate the onhover */
// find the layer pagination id
var feature = findFeatureById(hoveredItem);
if (feature) {
// use the pagination id to find the event, and then trigger the click for that event to show the popup
// also, pass a null event, since we don't necessarily have one.
feature.marker.events.listeners.click[0].func.call(feature, event)
}
}
function onFeatureUnselected(event) {
/* Do something here to indicate the onhover */
// find the layer pagination id
var feature = findFeatureById(hoveredItem);
if (feature) {
// use the pagination id to find the event, and then trigger the click for that event to show the popup
// also, pass a null event, since we don't necessarily have one.
feature.marker.events.listeners.click[0].func.call(feature, event)
}
/* Do something here to stop the indication of the onhover */
hoveredItem = null;
}
function findFeatureById(featureId) {
for (var key in map.layers) {
var layer = map.layers[key];
if (layer.hasOwnProperty('features')) {
for (var key1 in layer.features) {
var feature = layer.features[key1];
if (feature.hasOwnProperty('id') && feature.id == featureId) {
return feature;
}
}
}
}
return null;
}
also note that I keep map as a global so I don't have to reacquire it everytime I want to use it
After dojo drag and drop, once the page is submitted, I have to save the position of every item that has been placed into "targetZone". How can we save the position?
Eugen answered it here :
Dojo Drag and drop: how to retrieve order of items?
That would be the right way. If you look at the link above, you can save the resulting "orderedDataItems" object as a JSON ...
Look at the following function. It saves our DND "Lightbox" (dojo.dnd.source) to a JSON.
_it is the current raw dnd item
_it.data.item contains all your stuff you need to keep
in our case _it.data.item.label keeps the customized nodes (pictures, video, docs) as a string, we can use later to dojo.place it
it is the dnd item you want to save without dom nodes
E.g. if you drop items from a dijit tree to a arbitrary dojo dnd source / target:
_RAM or _S in our data.item we made before needs to be overwritten.
LBtoJson: function(){
var that = this;
var orderedLBitems = this.dndSource.getAllNodes().map(function(node){
var _it = that.dndSource.getItem(node.id);
var it = { data:{ item:{} }, label:'', type:'' };
if((_it.data.item._RAM)){_it.data.item._RAM={}}
if((_it.data.item._S)){_it.data.item._S={}}
it.data.item = dojo.clone(_it.data.item);
it.label = it.data.item.label[0]||it.data.item.label;
it.type = _it.type;
console.log( it );
return it;
});
var LBjson = dojo.toJson(orderedLBitems);
return LBjson;
}
By calling getAllNodes(), you'll receive a list of nodes in the order they are shown. So if you wanted to save a list in a specific order, you could do something similar to this:
var data;
var nodes = dndSrc.getAllNodes();
for(var i; i < nodes.length; i++)
{
data.push({id: nodes[i].id, order: i});
}
