I'm attempting to embed the very convenient Google Translate translate element into a webpage, which is super simple and works great, but I need to change the default text that displays in the resulting HTML:
Having worked with a number of Google APIsand js libraries, I figured this would be no problem as it would almost certainly be configurable, but having looked around for some time I can't find any reference to a property that let's you set this, and documentation in general seems to be pitiful. The basic code is:
<div id="google_translate_element"></div>
<script>
function googleTranslateElementInit() {
var translator = new google.translate.TranslateElement({
pageLanguage: 'en',
autoDisplay: false,
multilanguagePage: false,
layout: google.translate.TranslateElement.InlineLayout.SIMPLE
}, 'google_translate_element');
}
</script>
<script src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
Having dispaired of being able to set this as a property in the when I create the translator, I decided to hack it and use an onDOMNodeInserted listener to just change the resulting HTML once it had loaded into <div id="google_translate_element"></div>. I'm using jQuery here, so my code is:
$(document).ready(function(){
$('#google_translate_element').bind('DOMNodeInserted', function(event) {
$('.goog-te-menu-value span:first').html('Translate');
});
})
And here's where things get interesting. Chrome loads everything perfectly and does the innerHTML substitution beautifully. Internet Explorer (8) ignores the DOMNodeInserted listener altogether and the page loads as if the jQuery function was never called. Firefox (10) appears to load fine (but with no translate element at all) and then freezes, begins gobbling up memory, and crashes.
Any thoughts on how I can get this innerHTML substitution to work? If you're aware of a displayLabel : "Translate"-like property that is of course preferred, but barring that (and a really ugly setTimeout hack) is there any way I can get this to work?
You can do it using CSS, only it will not change the label when a language is selected.
#google_translate_element .goog-te-gadget-simple .goog-te-menu-value span:first-child{display: none;}
#google_translate_element .goog-te-gadget-simple .goog-te-menu-value:before{content: 'Translate'}
Like you I can't find out how to customize the gadget via init params but it appears possible to write your own customized gadget in HTML then invoke g.translate functionality on it. See http://www.toronto.ca/ (page footer). I'm afraid you will have to do some more digging to see exactly how it's done.
This use of g.translate is also referenced here. Unfortunately the discussion is quite old now but hopefully still relevant.
I'm using this code which checks every 3ms if the translate module has been yet loaded into the page; if so, it then updates the text and clears the interval check after.
function cleartimer() {
setTimeout(function(){
window.clearInterval(myVar);
}, 1000);
}
function myTimer() {
if ($('.goog-te-menu-value > span:first-child').length) {
$('.goog-te-menu-value > span:first-child').html('Translate');
cleartimer();
}
}
var myVar = setInterval(function(){ myTimer() }, 300);

I'm using the code below to delay the loading of a div until the entire web page is loaded. It works perfectly in Firefox and Safari (because they each have lines in the code to make sure it works specifically for each, I haven't tested IE yet), but not in Chrome (which should, I think, work with window.onload).
Could somebody please help me out with this?
<script type="text/javascript">
function insertFB(){
var html='<div class="fb-page" data-href="https://www.facebook.com/bobcaputolivingwell" data-small-header="false" data-adapt-container-width="true" data-hide-cover="false" data-show-facepile="true" data-show-posts="true"><div class="fb-xfbml-parse-ignore"><blockquote cite="https://www.facebook.com/bobcaputolivingwell">Bob Caputo Living Well</blockquote></div></div>';
$("#FB_PAGE").html(html);
}
if (document.addEventListener){
document.addEventListener("DOMContentLoaded", insertFB, false);
}
if (/WebKit/i.test(navigator.userAgent)){
var _timer = setinterval(function(){
if(/loaded|complete/.test(document.readyState)){
insertFB();
}
},10);
}
window.onload = insertFB();
</script>
Well, firstly I'll answer specifically your question:
It's not working in Google Chrome, because you're using setinterval, and Javascript is a case-sensitive language. The correct name of the method is setInterval.
Besides that, your code is full of errors, you check for a method inside document, and don't use else if to check the others, so you always check all, and probably call the method you want two or more times.
The other thing is that you're using setInterval but you're never clearing the interval, so that thing is gonna run every 10ms forever.
And finally, the last thing, you're calling the insertFB function when you're trying to attach it to the onload event. You shouldn't be using parenthesis for that.
Take a look at Can I use addEventListener? and at Can I use DOMContentLoaded?, and you'll see that it's supported by all major browsers, even some old ones, and you should only use another way, if you really need to support IE8 (nowadays it's unlikely).
I was testing stuff in JSFiddle (with jQuery 1.9.0 included as an external ressource), and I basically had something like this in my HTML :
Hello world!
Under Chrome Inspector (v.35) / Script / index file, I spotted that AdBlock Plus (even toggled off) probably added these lines in my HTML's source :
<script>
(function () {
with(this[2]) {
with(this[1]) {
with(this[0]) {
return function (event) {
alert('Hello world!'); //Same as my onclick up there
};
}
}
}
})
</script>
I've never seen something like this, I guess it is meant to be a protection, but I can't figure what's its purpose.
What could do this code? Any guess?
Disclaimer : I'm sorry, I tried hard but I'm absolutely unable to reproduce this for the moment, apart for my own case...
Edit
I though it was impossible to reproduce even by opening my fiddle in another tab, but in fact, it seems to be possible. So, here's the fiddle, activate AdBlock plus, and here's how to see this :
Meanwhile, I'm trying to create a case where it's 100% reproductible, I'll post it here as soon as possible.
I am trying to load Skyscanner API dynamically but it doesn't seem to work. I tried every possible way I could think of and all it happens the content disappears.
I tried console.log which gives no results; I tried elements from chrome's developers tools and while all the content's css remains the same, still the content disappears (I thought it could be adding display:none on the html/body sort of). I tried all Google's asynch tricks, yet again blank page. I tried all js plugins for async loading with still the same results.
Skyscanner's API documentation is poor and while they offer a callback it doesn't work the way google's API's callback do.
Example: http://jsfiddle.net/7TWYC/
Example with loading API in head section: http://jsfiddle.net/s2HkR/
So how can I load the api on button click or async? Without the file being in the HEAD section. If there is a way to prevent the document.write to make the page blank or any other way. I wouldn't mind using plain js, jQuery or PHP.
EDIT:
I've set a bounty to 250 ontop of the 50 I had previously.
Orlando Leite answered a really close idea on how to make this asynch api load although some features doesn't work such as selecting dates and I am not able to set styling.
I am looking for an answer of which I will be able to use all the features so that it works as it would work if it was loading on load.
Here is the updated fiddle by Orlando: http://jsfiddle.net/cxysA/12/

EDIT 2 ON Gijs ANSWER:
Gijs mentioned two links onto overwriting document.write. That sounds an awesome idea but I think it is not possible to accomplish what I am trying.
I used John's Resig way to prevent document.write of which can be found here: http://ejohn.org/blog/xhtml-documentwrite-and-adsense/
When I used this method, I load the API successfuly but the snippets.js file is not loading at all.
Fiddle: http://jsfiddle.net/9HX7N/
I belive what you want is it:
function loadSkyscanner()
{
function loaded()
{
t.skyscanner.load('snippets', '1', {'nocss' : true});
var snippet = new t.skyscanner.snippets.SearchPanelControl();
snippet.setCurrency('GBP');
snippet.setDeparture('uk');
snippet.draw(document.getElementById('snippet_searchpanel'));
}
var t = document.getElementById('sky_loader').contentWindow;
var head = t.document.getElementsByTagName('head')[0];
var script = document.createElement('script');
script.type = 'text/javascript';
script.onreadystatechange= function() {
if(this.readyState == 'complete') loaded();
}
script.onload= loaded;
script.src= 'http://api.skyscanner.net/api.ashx?key=PUT_HERE_YOUR_SKYSCANNER_API_KEY';
head.appendChild(script);
}
$("button").click(function(e)
{
loadSkyscanner();
});
It's load skyscanner in iframe#sky_loader, after call loaded function to create the SearchPanelControl. But in the end, snippet draws in the main document. It's really a bizarre workaround, but it works.
The only restriction is, you need a iframe. But you can hide it using display:none.
A working example
EDIT
Sorry guy, I didn't see it. Now we can see how awful is skyscanner API. It puts two divs to make the autocomplete, but not relative to the element you call to draw, but the document.
When a script is loaded in a iframe, document is the iframe document.
There is a solution, but I don't recommend, is really a workaround:
function loadSkyscanner()
{
var t;
this.skyscanner;
var iframe = $("<iframe id=\"sky_loader\" src=\"http://fiddle.jshell.net/orlleite/2TqDu/6/show/\"></iframe>");
function realWorkaround()
{
var tbody = t.document.getElementsByTagName("body")[0];
var body = document.getElementsByTagName("body")[0];
while( tbody.children.length != 0 )
{
var temp = tbody.children[0];
tbody.removeChild( temp );
body.appendChild( temp );
}
}
function snippetLoaded()
{
skyscanner = t.skyscanner;
var snippet = new skyscanner.snippets.SearchPanelControl();
snippet.setCurrency('GBP');
snippet.setDeparture('uk');
snippet.draw(document.getElementById('snippet_searchpanel'));
setTimeout( realWorkaround, 2000 );
}
var loaded = function()
{
console.log( "loaded" );
t = document.getElementById('sky_loader').contentWindow;
t.onLoadSnippets( snippetLoaded );
}
$("body").append(iframe);
iframe.load(loaded);
}
$("button").click(function(e)
{
loadSkyscanner();
});
Load a iframe with another html who loads and callback when the snippet is loaded. After loaded create the snippet where you want and after set a timeout because we can't know when the SearchPanelControl is loaded. This realWorkaround move the autocomplete divs to the main document.
You can see a work example here
The iframe loaded is this
EDIT
Fixed the bug you found and updated the link.
the for loop has gone and added a while, works better now.
while( tbody.children.length != 0 )
{
var temp = tbody.children[0];
tbody.removeChild( temp );
body.appendChild( temp );
}
For problematic cases like this, you can just overwrite document.write. Hacky as hell, but it works and you get to decide where all the content goes. See eg. this blogpost by John Resig. This ignores IE, but with a bit of work the trick works in IE as well, see eg. this blogpost.
So, I'd suggest overwriting document.write with your own function, batch up the output where necessary, and put it where you like (eg. in a div at the bottom of your <body>'). That should prevent the script from nuking your page's content.
Edit: OK, so I had/took some time to look into this script. For future reference, use something like http://jsbeautifier.org/ to investigate third-party scripts. Much easier to read that way. Fortunately, there is barely any obfuscation/minification at all, and so you have a supplement for their API documentation (which I was unable to find, by the way -- I only found 'code wizards', which I had no interest in).
Here's an almost-working example: http://jsfiddle.net/a8q2s/1/
Here's the steps I took:
override document.write. This needs to happen before you load the initial script. Your replacement function should append their string of code into the DOM. Don't call the old document.write, that'll just get you errors and won't do what you want anyway. In this case you're lucky because all the content is in a single document.write call (check the source of the initial script). If this weren't the case, you'd have to batch everything up until the HTML they'd given you was valid and/or you were sure there was nothing else coming.
load the initial script on the button click with jQuery's $.getScript or equivalent. Pass a callback function (I used a named function reference for clarity, but you can inline it if you prefer).
Tell Skyscanner to load the module.
Edit #2: Hah, they have an API (skyscanner.loadAndWait) for getting a callback once their script has loaded. Using that works:
http://jsfiddle.net/a8q2s/3/
(note: this still seems to use a timeout loop internally)
In the skyrunner.js file they are using document.write to make the page blank on load call back... So here are some consequences in your scenario..
This is making page blank when you click on button.
So, it removes everything from page even 'jQuery.js' that is why call back is not working.. i.e main function is cannot be invoked as this is written using jQuery.
And you have missed a target 'div' tag with id = map(according to the code). Actually this is the target where map loads.
Another thing i have observed is maps is not actually a div in current context, that is maps api to load.
Here you must go with the Old school approach, That is.. You should include your skyrunner.js file at the top of the head content.
So try downloading that file and include in head tag.
Thanks
I have a jquery code.
$(window).load(function() {
document.title = $("#myid").text(); //not working in FF
});
Here I have used $(window).load(function() because in the #myid I am getting value through another javascript, if I use ready(), its giving me error. so I am first loading the window then start reading value.
Now in IE, after the window loads itself , I am getting the value of document.title,
but for FF its coming as blank.undefined.
Why? any idea or alternate sln.
It might be a rendering/timing issue.
How are you setting the #myid text? Im assuming you are running this code on page load?
Personaly on another note, i like to use the shorthand version of jQuery DOM ready, this might also fix your problem too.
jQuery(function(){
document.title = jQuery("#myid").text();
});
And i would make sure that you call it at the end of the body or ideally in the head tag.
I think it is possible that firefox triggers ready and load at the same time when it loads quickly (localhost, small experiment page with one div, etc.)
Why not put the title setting in the ready function right after getting it? If You put it in a div, You can put it in the title too.
I didn't check this code and it isn't a good way, but maybe it help you...
If your code isn't working in Firefox only, you can check browser by Javascript and execute my code for Firefox only.
<script type="text/javascript">
var timerId = 0;
function checkElement() {
// If don't work: try .html() or $("#myid").text() != undefined or smth like this
if($("#myid").text()) {
document.title = $("#myid").text();
clearInterval(timerId);
}
}
$(document).ready(function() {
timerId = setInterval('checkElement()', 500);
});
</script>
I have a website with a form that uses TinyMCE; independently, I use jQuery. When I load the form from staging server on Firefox 3 (MacOS X, Linux), TinyMCE doesn't finish loading. There is an error in Firefox console, saying that t.getBody() returned null. t.getBody(), as far as I understand from TinyMCE docs, is a function that returns document's body element to be inspected for some features. Problem doesn't occur when I use Safari, nor when I use Firefox with the same site running from localhost.
Original, failing JavaScript-related code looked like this:
<script type="text/javascript" src="http://static.alfa.foo.pl/json2.js"></script>
<script type="text/javascript" src="http://static.alfa.foo.pl/jquery.js"></script>
<script type="text/javascript" src="http://static.alfa.foo.pl/jquery.ui.js"></script>
<script type="text/javascript" src="http://static.alfa.foo.pl/tiny_mce/tiny_mce.js"></script>
<script type="text/javascript">
tinyMCE.init({ mode:"specific_textareas", editor_selector:"mce", theme:"simple", language:"pl" });
</script>
<script type="text/javascript" src="http://static.alfa.foo.pl/jquery.jeditable.js"></script>
<script type="text/javascript" src="http://static.alfa.foo.pl/jquery.tinymce.js"></script>
<script type="text/javascript" charset="utf-8" src="http://static.alfa.foo.pl/foo.js"></script>
<script type="text/javascript">
$(document).ready(function(){
/* jQuery initialization */ });
</script>
I tried changing script loading order, moving tinyMCE.init() call to the <script/> tag containing $(document).ready() call—before, after, and inside this call. No result. When tinyMCE.init() was called from within $(document).ready() handler, the browser did hang on request—looks like it was too late to call the init function.
Then, after googling a bit about using TinyMCE together with jQuery, I changed tinyMCE.init() call to:
tinyMCE.init({ mode:"none", theme:"simple", language:"pl" });
and added following jQuery call to the $(document).ready() handler:
$(".mce").each( function(i) { tinyMCE.execCommand("mceAddControl",true,this.id); });
Still the same error. But, and here's where things start to look like real voodoo, when I added alert(i); before the tinyMCE.execCommand() call, alerts were given, and TinyMCE textareas were initialized correctly. I figured this can be a matter of delay introduced by waiting for user dismissing the alert, so I introduced a second of delay by changing the call, still within the $(document).ready() handler, to following:
setTimeout('$(".mce").each( function(i) { tinyMCE.execCommand("mceAddControl",true,this.id); });',1000);
With the timeout, TinyMCE textareas initialize correctly, but it's duct taping around the real problem. The problem looks like an evident race condition (especially when I consider that on the same browser, but when server is on localhost, problem doesn't occur). But isn't JavaScript execution single-threaded? Could anybody please enlighten me as to what's going on here, where is the actual problem, and what can I do to have it actually fixed?
The browser executes scripts in the order they're loaded, not written. Your immediate scripts -- tinyMCE.init(...) and $(document.ready(...)); -- can execute before the files finish loading.
So, the problem is probably network latency -- especially with 6 separate scripts (each requiring a different HTTP conversation between the browser and server). So, the browser is probably trying to execute tinyMCE.init() before tiny_mce.js has finished being parsed and tinyMCE is fully defined.
If don't have Firebug, get it. ;)
It has a Net tab that will show you how long it's taking all of your scripts to load.
While you may consider the setTimeout to be duct taping, it's actually a decent solution. Only problem I see is that it assumes 1 second will always fix. A fast connection and they could see the pause. A slow connection and it doesn't wait long enough -- you still get the error.
Alternatively, you might be able to use window.onload -- assuming jQuery isn't already using it. (Can anyone else verify?)
window.onload = function () {
tinyMCE.init(...);
$(document).ready(...);
};
Also, was that a direct copy?
<script type="text/javascript">
$(document).ready(function(){
/* jQuery initialization */ }
</script>
It's missing the ) ending ready:
<script type="text/javascript">
$(document).ready(function(){
/* jQuery initialization */ })
</script>
Missing punctuation can cause plenty of damage. The parser is just going to keep reading until it finds it -- messing up anything in between.
Since this is the first page which came in google when I asked myself the same question, this is what i found about this problem.

There's a callback function in tinyMCE which is fired when the component is loaded and ready. you can use it like this :
tinyMCE.init({
...
setup : function(ed) {
ed.onInit.add(function(ed) {
console.log('Editor is loaded: ' + ed.id);
});
}
});
If you are using jquery.tinymce.js then you don't need tiny_mce.js because TinyMCE will try to load it with an ajax request. If you are finding that window.tinymce (or simply tinymce) is undefined then this means that the ajax is not yet complete (which might explain why using setTimeout worked for you). This is the typical order of events:
Load jquery.js with a script tag (or google load).
Load TinyMCE's jQuery plugin, jquery.tinymce.js, with a script tag.
Document ready event fires; this is where you call .tinymce(settings) on your textareas. E.g.
$('textarea').tinymce({ script_url: '/tiny_mce/tiny_mce.js' })
Load tiny_mce.js this step is done for you by TinyMCE's jQuery plugin, but it could happen after the document ready event fires.
Sometimes you might really need to access window.tinymce, here's the safest way to do it:
$(document).tinymce({
'script_url': '/tiny_mce/tiny_mce.js'
'setup': function() {
alert(tinymce);
}
});
TinyMCE will go so far as to create a tinymce.Editor object and execute the setup callback. None of the editor's events are triggered and the editor object created for the document is not added to tinymce.editors.
I also found that TinyMCE's ajax call was interfering with my .ajaxStop functions so I also used a setTimeout:
$(document).tinymce({
'script_url': '/tiny_mce/tiny_mce.js'
'setup': function() {
setTimeout(function () {
$(document).ajaxStart(function(e) {/* stuff /});
$(document).ajaxStop(function(e) {/ stuff */});
}, 0);
}
});
