I try to limit the number of possible indentations in TinyMCE but I can't find an option to do them, do you have an idea? Thank you
TinyMCE fires a variety of events as you work with the content. If you want to stop someone from indenting the content you would have to capture the event that is triggered when someone clicks the indent button and decide the action you want to take.
Here are some examples of the types of code you can use to listen for events:
setup: function (editor) {
editor.on('init', function (e) {
editor.setContent('<p>This is the content in TinyMCE!</p>');
});
editor.on('init keydown change click blur', function (e) {
document.getElementById('data').innerText = editor.getContent();
});
editor.on('ExecCommand', function (e) {
console.log('ExecCommand:', e.command);
if (e.command === "indent") {
console.log('Someone clicked the indent key');
}
if (e.command === "outdent") {
console.log('Someone clicked the outdent key');
}
});
editor.on('NodeChange', function(e) {
console.log('NodeChange event fired', e);
console.log(editor.selection.getNode());
});
editor.on('change', function (e) {
console.log('change event fired');
console.log(e);
});
}
Here is a TinyMCE Fiddle that shows some of this sort of code in action: http://fiddle.tinymce.com/6fhaab/1
Once you know that someone clicked the indent/outdent these sorts of events give you access to the content that TinyMCE is about to modify and you can do what you need to modify or cancel the event.

I am redrawing layers on style.load event and removing the layers
map.on('style.load', function() {
loadByBounds(tempBounds)
});
function loadByBounds(b) {
if (map.getLayer("cluster-count")) {
map.removeLayer("cluster-count");
}
...
map.on('click', 'unclustered-point', function(e) {
var popup = new mapboxgl.Popup()
.setLngLat(e.features[0].geometry.coordinates)
.setHTML(text)
.addTo(map);
})}
But how to remove map.on('click') events? As when I click the point the Popup() displays 2 times. And when I change layer one more time the onclick event fires 3 times and so on. So I think I have to remove the click event but how? Thanks
You might wanna use map.once(). This will add a listener that will be called only once to a specified event type. However after 1 click event got fired this event listener won't listen to any further click events.

With map.off() it's basically the opposite of map.on() and you can use it to unregister any applied event listeners. However you would need to add event listeners without an anonymous function in order to use map.off().
https://www.mapbox.com/mapbox-gl-js/api/#map#off
// you would need to use a named function
function clickHandler(e) {
// handle click
}
map.on('click', clickHandler);
// then you can use
map.off('click', clickHandler);
// With an anonymous function you won't be able to use map.off
map.on('click', (e) => {
// handle click
});
To prevent your app from registering multiple listeners you maybe need to set a flag that gets set after your first event listener got applied.
let notListening = true;
function loadByBounds(b) {
// ....
if (notListening) {
notListening = false;
map.on('click', (e) => {
// do something
});
}
}
I am using 1000hz BootstrapValidator and after click on button (not submit because I need to stay on page without refresh) I want to check if form is correct.
I just can call $("#form2").validator('validate'); but I am not able to get return value.
I know about isDefaultPrevented but it is called after submit and I do not want submit.
$('#form').validator().on('submit', function (e) {
if (e.isDefaultPrevented()) {
// handle the invalid form...
} else {
// everything looks good!
}
})
Yeah one way is to change the from submit button type from submit to buttonand handle the validation via click function and count the length if any input field has error ($('#form2').validator('validate').has('.has-error').length) and handle it with if/else condition.
$(document).ready(function(){
$("#myButton").click(function() {
if ($('#form2').validator('validate').has('.has-error').length) {
alert('SOMETHING WRONG');
} else {
//$("#form2").submit();
alert('EVERYTHING IS GOOD');
}
});
});
Fiddle Example
I am trying to add some validation logic to the code plugin for tinyMCE.
It seems, however, that when a window's onSubmit function is called, the window closes by default.
The onSubmit function currently looks like this:
onSubmit: function (e) {
// We get a lovely "Wrong document" error in IE 11 if we
// don't move the focus to the editor before creating an undo
editor.focus();
editor.undoManager.transact(function () {
editor.setContent(e.data.code);
});
editor.selection.setCursorLocation();
editor.nodeChanged();
}
What I would like to do is add some validation logic to the plugin to prevent tinyMCE from reformatting invalid html and, rather, display a message that the html is invalid. Essentially, something like this:
onSubmit: function (e) {
// We get a lovely "Wrong document" error in IE 11 if we
// don't move the focus to the editor before creating an undo
var isCodeValid = true;
//check if code valid
isCodeValid = ValidateCode(e.data.code);
if (isCodeValid) {
//if code valid, send to tinyMCE to let it do it's thing
editor.focus();
editor.undoManager.transact(function () {
editor.setContent(e.data.code);
});
editor.selection.setCursorLocation();
editor.nodeChanged();
}
else {
//if code invalid, display error message and keep text editor window open
tinyMCE.activeEditor.windowManager.alert("Your HTML is invalid. Please check your code and try submitting again.");
return;
}
}
However, it seems that the onSubmit function closes the text editor window regardless. I was wondering if there is a way to stop it from doing this. I have scoured the documentation which leaves much to be explained and have looked at other plugins as examples. The closest I can find is the searchandreplce plugin. The 'Find' button calls the onSubmit function, but it seems to stay open if the 'find' text field is blank. However, the logic behind it seems very different from what I can use in the Code plugin as it is.
Can anyone who is familiar with the tinyMCE API give me any ideas on how to prevent the window from closing when onSubmit is called? Or do I have to go another route?
As per this question the way to cancel an event is to return false;. This will keep the popup open. Your code would then become:
onSubmit: function (e) {
// We get a lovely "Wrong document" error in IE 11 if we
// don't move the focus to the editor before creating an undo
var isCodeValid = true;
//check if code valid
isCodeValid = ValidateCode(e.data.code);
if (isCodeValid) {
//if code valid, send to tinyMCE to let it do it's thing
editor.focus();
editor.undoManager.transact(function () {
editor.setContent(e.data.code);
});
editor.selection.setCursorLocation();
editor.nodeChanged();
}
else {
//if code invalid, display error message and keep text editor window open
tinyMCE.activeEditor.windowManager.alert("Your HTML is invalid. Please check your code and try submitting again.");
return false;
}
}
I figured it out finally. All you need to do is add e.preventDefault(); at the start of the onSubmit function and the window will not close. The documentation was no help, but looking at the searchandreplace plugin as an example lead me to the answer. What I have now is like this:
onSubmit: function (e) {
e.preventDefault();
// We get a lovely "Wrong document" error in IE 11 if we
// don't move the focus to the editor before creating an undo
var isCodeValid = true;
//check if code valid
isCodeValid = ValidateCode(e.data.code);
if (isCodeValid) {
//if code valid, send to tinyMCE to let it do it's thing
editor.focus();
editor.undoManager.transact(function () {
editor.setContent(e.data.code);
});
editor.selection.setCursorLocation();
editor.nodeChanged();
}
else {
//if code invalid, display error message and keep text editor window open
tinyMCE.activeEditor.windowManager.alert("Your HTML is invalid. Please check your code and try submitting again.");
return;
}
}
e.PreventDefault() seems to stop the default behavior of the onSubmit function.
i have a TreeView that once the user drops the item to the desired position, it displays a dialog box and asks for confirmation, if the user selects cancel, how would i also cancel the placement of the item so it goes back to its original position? my current code is below but isnt working:
var newDiv = $(document.createElement('div'));
newDiv.html('Are you sure you want to move the item: ' + title);
newDiv.dialog( {
autoOpen: true,
width: 600,
buttons: {
"Save": function () {
$(this).dialog("close");
},
"Cancel": function () {
$(this).dialog("close");
e.setValid = false;
}
}
});
I have also tried doing the same kind of code on the dragend event and using e.preventDefault(); with no more luck
The drop event handler provides the setValid function, which can prevent the drop from occurring. For example:
function onDrop(e) {
e.setValid(confirm('Do you wish to move this item here?'));
}
$("#treeView").kendoTreeView({
// ...
dragAndDrop: true,
drop: onDrop
});
I've written a fiddle which demonstrates how this works.
Did you try to use the drop event and call prevent default there if the condition is not satisfied?
When I use the following jquery live function
$("a[rel]").live('click', function () {
e.preventDefault();
alert('clicked');
});
e.preventDefault(); does not work, because the action behind the a tag is still fired.
How do I prevent an event when I use jQuery.live?
Don't forget the e inside the function argument list.
$("a[rel]").live('click', function (e) {
e.preventDefault();
alert('clicked');
});
You could also try adding
return false;
to the function.
You are missing e argument to the function, try this:
$("a[rel]").live('click', function (e) {
e.preventDefault();
alert('clicked');
});
