I am creating Rich Text editor using UIWebView in iOs sdk.I am using java script & HTML code to implement all functionality & using webview as editable content. Now my problem is that I want to insert page break in UIWebView using java-script/Html but page break option is not working in UIWebView.How I can insert page break option in UIWebview?
I have done this after too much search with JS
function makePageBreak(){
insertHtmlAtCursor('<div id="MyInsertPageBreak" class="pagebreak" ></div>');
}
function insertHtmlAtCursor(html) {
var range, node;
if (window.getSelection && window.getSelection().getRangeAt) {
range = window.getSelection().getRangeAt(0);
node = range.createContextualFragment(html);
range.insertNode(node);
} else if (document.selection && document.selection.createRange) {
document.selection.createRange().pasteHTML(html);
}
}
This worked for me. Hope will help you.

What I'm trying to do is, When I click on hotspot it should open a popup with little text. It is okay if the text is static, Is there any way we can make it possible? FYI I'm creating it for the web.
Thanks in advance:)
I just started with google VR. I know it's a late reply but it is very possible.
function onVrViewLoad() {
// init scene here and then:
vrView.on('click', onHotspotClick)
}
function onHotspotClick(e) {
console.log('onHotspotClick', e.id)
triggerSidebar(e.id)
}
function triggerSidebar(id) {
// add the class
switch (id) {
case 'item':
document.querySelector('aside.item').classList.add('...')
break
}
}
I have created a chrome extension to allow users to right-click in a textbox, and insert special characters. This works on many sites such as StackOverflow, but does not work on sites such as Facebook. This is because Facebook is not using a standard text box form control. Instead for each line in a text message, it seems to be using a div > div > span > span construct. Is there a way to create a Chrome extension to target page components such as this?
An portion of my Chrome extension code looks like this:
main.js:
chrome.contextMenus.create({
title: "\u038F",
contexts:["editable"],
onclick: function(info, tab){
chrome.tabs.sendMessage(tab.id, {action: "insertCharacter", character: '\u038F'});
}
});
content.js
chrome.extension.onMessage.addListener(function(request, sender, sendResponse){
var objField = document.activeElement;
if (request.action == "insertCharacter"){
insertAtCursor(objField, request.character);
}
});
function insertAtCursor(sField, sValue){
if (sField.selectionStart || sField.selectionStart == '0'){
var nStart = sField.selectionStart;
var nEnd = sField.selectionEnd;
sField.value = sField.value.substring(0, nStart) + sValue + sField.value.substring(nEnd, sField.value.length);
sField.selectionStart = nStart + sValue.length;
sField.selectionEnd = nStart + sValue.length;
}
else {
sField.value += sValue;
}
}
Is there a more general purpose way I can do this to handle various situations on different sites? If not, is there a way to specifically target Facebook as most of the time myself (and likely others) are going to be using my extension on Facebook. (Of course having it work for email sites such as GMail would be a benefit as well).
In case it helps someone else, this is what I modified my code to based on wOxxOm's suggestion:
chrome.extension.onMessage.addListener(function(request, sender, sendResponse){
if (request.action == "insertCharacter"){
insertAtCursor(request.character);
}
});
function insertAtCursor(sValue){
document.execCommand("insertText", false, sValue);
}
It's much more compact than my original approach and insertText handles the selection aspect automatically.
I am trying to user Custom Drag appearance in smart gwt. how can i implement it.
Current when using DragAppearance.TRACKER its show on 10px square i want a lable with caption Drag to Lineup.
vLayout1.setDragAppearance(DragAppearance.TRACKER);
vLayout1.setCanHover(true);
vLayout1.setCursor(Cursor.HAND);
I hope, the following links will help you
https://github.com/moravianlibrary/MEditor/blob/master/editor-editation/src/main/java/cz/mzk/editor/client/view/ModifyView.java#L1100:L1104
https://github.com/moravianlibrary/MEditor/blob/master/editor-common/editor-common-client/src/main/java/cz/mzk/editor/client/view/other/EditorDragMoveHandler.java
Override BaseWidget.setDragTracker and provide required content using EventHandler.setDragTracker.
VLayout vLayout1 = new VLayout() {
#Override
protected boolean setDragTracker() {
EventHandler.setDragTracker("<pre>Drag to Lineup</pre>");
return false;
}
};
vLayout1.setCanDrop(true);
vLayout1.setCanDrag(true);
vLayout1.setDragAppearance(DragAppearance.TRACKER);
EventHandler.setDragTracker accepts any valid html code and <pre/> tags were used above to avoid word wrap.
Check following sample in SmartGWT showcase:

i have StartPreviewAsync api to show camera preview on screen in C#
but not available in javascript ,so how can i get same preview(output) in javascript template??
or is any way to deploy xaml on javascript??
WinJS seems to have a different API for handling Camera Previews. I'd take a look at this example on MSDN for more details. Namely, in BasicCapture.js, we see the following function, startPreview:
function startPreview() {
displayStatus("Starting preview");
id("btnStartPreview" + scenarioId).disabled = true;
var video = id("previewVideo" + scenarioId);
video.src = URL.createObjectURL(mediaCaptureMgr, { oneTimeOnly: true });
video.play();
displayStatus("Preview started");
getCameraSettings();
// Initialize sliders.
for (var i = 0; i < cameraControlSliders.length; i++) {
cameraControlSliders[i].slider.disabled = false;
initSlider(cameraControlSliders[i]);
}
}
To answer your second question, the only way to load Javascript into a XAML application would be through the WebView control, and even that would not be allowed to directly control the different controls of the XAML UI. If you want to do XAML, you have to stick to C#, VB, or C++.
I'm making a mobile-app using Phonegap and HTML. Now I'm using the google maps/places autocomplete feature. The problem is: if I run it in my browser on my computer everything works fine and I choose a suggestion to use out of the autocomplete list - if I deploy it on my mobile I still get suggestions but I'm not able to tap one. It seems the "suggestion-overlay" is just ignored and I can tap on the page. Is there a possibility to put focus on the list of suggestions or something that way ?
Hope someone can help me. Thanks in advance.
There is indeed a conflict with FastClick and PAC. I found that I needed to add the needsclick class to both the pac-item and all its children.
$(document).on({
'DOMNodeInserted': function() {
$('.pac-item, .pac-item span', this).addClass('needsclick');
}
}, '.pac-container');
There is currently a pull request on github, but this hasn't been merged yet.
However, you can simply use this patched version of fastclick.
The patch adds the excludeNode option which let's you exclude DOM nodes handled by fastclick via regex. This is how I used it to make google autocomplete work with fastclick:
FastClick.attach(document.body, {
excludeNode: '^pac-'
});
This reply may be too late. But might be helpful for others.
I had the same issue and after debugging for hours, I found out this issue was because of adding "FastClick" library. After removing this, it worked as usual.
So for having fastClick and google suggestions, I have added this code in geo autocomplete
jQuery.fn.addGeoComplete = function(e){
var input = this;
$(input).attr("autocomplete" , "off");
var id = input.attr("id");
$(input).on("keypress", function(e){
var input = this;
var defaultBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(37.2555, -121.9245),
new google.maps.LatLng(37.2555, -121.9245));
var options = {
bounds: defaultBounds,
mapkey: "xxx"
};
//Fix for fastclick issue
var g_autocomplete = $("body > .pac-container").filter(":visible");
g_autocomplete.bind('DOMNodeInserted DOMNodeRemoved', function(event) {
$(".pac-item", this).addClass("needsclick");
});
//End of fix
autocomplete = new google.maps.places.Autocomplete(document.getElementById(id), options);
google.maps.event.addListener(autocomplete, 'place_changed', function() {
//Handle place selection
});
});
}
if you are using Framework 7, it has a custom implementation of FastClicks. Instead of the needsclick class, F7 has no-fastclick. The function below is how it is implemented in F7:
function targetNeedsFastClick(el) {
var $el = $(el);
if (el.nodeName.toLowerCase() === 'input' && el.type === 'file') return false;
if ($el.hasClass('no-fastclick') || $el.parents('.no-fastclick').length > 0) return false;
return true;
}
So as suggested in other comments, you will only have to add the .no-fastclick class to .pac-item and in all its children
I was having the same problem,
I realized what the problem was that probably the focusout event of pac-container happens before the tap event of the pac-item (only in phonegap built-in browser).
The only way I could solve this, is to add padding-bottom to the input when it is focused and change the top attribute of the pac-container, so that the pac-container resides within the borders of the input.
Therefore when user clicks on item in list the focusout event is not fired.
It's dirty, but it works
worked perfectly for me :
$(document).on({
'DOMNodeInserted': function() {
$('.pac-item, .pac-item span', this).addClass('needsclick');
}
}, '.pac-container');
