I want to load the content of a webpage in a div. Here's my code:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
When the this item is clicked, the webpage should be loaded inside the content id:
<ul><li><a id="menu_top" href='testing.html'><span>My account</span></a></li></ul>
<div id="content"> </div>
JS:
$("#menu_top").click(function() {
var href = $ (this).attr('href');
alert(href);
$("#content").load(href);
return false;
});
testing.html:
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
</head>
<body>
SUCCESS!
</body>
</html>
Unfortunately, the above code does not work. I have checked it multiple times but could not find the issue.
#Milind Anantwar is correct - must have the $(document).ready wrap your JS:
$(document).ready(function(){
$("#menu_top").click(function() {
var href = $ (this).attr('href');
alert(href);
$("#content").load(href);
return false;
});
});
I also tested whether or not the UL or OL tags affected it as #psicopoo mentioned, but it didn't seem to in Chrome. *ALSO, make sure that "testing.html" is a valid page to load.
*As noted on http://api.jquery.com/load/: "Due to browser security restrictions, most "Ajax" requests are subject to the same origin policy; the request can not successfully retrieve data from a different domain, subdomain, port, or protocol."
I think you're encountering an issue with the page you're trying to load. I copied your code exactly and it works in Fiddle, see if this works for you, if so, it's probably your page:
testing.html

I'm actually trying to access variable of other HTML file using JS.
I mean, I have a file (file1.htm) that open dialog box and I would like to send information of the file selected to another file (file2.htm) and modify a value in this file. I found solution but only for JS files, and not HTML :/
I had already done it with 2 files but file1a was the parent of the other, so I used
parent.framWin = window; in file2a and
framWin.divX=document.getElementById("one").offsetWidth; for example in file1a to modify the variable divX in file2a (I'm pretty sure this is not the best solution, but it works ;) ). Here, in this case, file1 and file2 are not parent, and they are just located in the same folder.
I tried <script type="text/javascript" src="file1.htm"> to access var but it doesn't seem to work.
Do you have any idea how I can accomplish this?
Thanks a lot!
(Here's my code :
file1.htm :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<script type="text/javascript">

function OK(e){
var name = document.getElementById("dialog").value;
//Here I would like to do something like File2.NameSpace1 = name;
//And File2.modifyMyName(); // But here, it's another question, to use JS script in another file ;)
}

document.GetElementById("first").src = NameSpace1;
}
//-->
</script>
</head>
<body>
<div>
<img src ="" id="first" />
</div>
</body>
I know this won't work properly because there are some errors here in the syntax. But the problem is visible ;)
Thanks again :)
You can't simply modify the content of file on the server using client side code.
The examples you've cited just change the data that is loaded into the browser at the time the code runs while leaving the data on the server untouched.
There are two approaches you can take to this:
Store the changes in the browser.
In page one, use localstorage to record information about the change you want to make. (You'd probably want to convert the image into a data: scheme URL to achieve this given your example code).
In page two, have some more JS that reads from localstorage and uses that information to make the change to itself after it loads.
Send the changes to the server.
Submit a form (so you don't need to use client side code at all) or use Ajax to send information about the change to the server.
Have server side code read it and then store it in a session (if you want the change to be on a per-user basis) or somewhere more permanent (in a database if you are sensible but you could modify the file directly) (if you want it to be shared between users).
Page two would then be a server side program that would read that data and use it to generate the page.
You can use localStorage to perform this operation.
function OK(e){
var name = document.getElementById("dialog").value;
window.localStorage.setItem('dialogValue', "Name");
}
And In your file2.html
function modifyMyName(){
var NameSpace1 = window.localStorage.getItem('dialogValue');
document.GetElementById("first").src = NameSpace1;
}
I'm fairly new in using Facebook javascript SDK and I have no idea what I am doing!
I'm trying to like a facebook post using Facebook javascript SDk in my html page.
My full code this:

<title>Untitled Document</title>
</head>
<body>
<div id="bod" style="width:100%; height:100px; background:#000;"></div>
<script>
$( "#bod" ).click(function() {
FB.api("/10153XXXXXXXXXX/likes", 'post',function(response) {
if(response === true) {
alert("done!");
}
});
});
</script>
</body>
</html>
I thought this code will like the given post (its ID is 10153XXXXXXXXXX) once i click on the div #bod but when I click on the div, nothing happens and I don't even get the alert(); at all!
could someone please advise on this issue and let me know what I'm doing wrong?
First of all you'll need to initialize the FB SDK.
Then, in order to call the API you'll need a valid access token therefore, you'll need to login the user using your App.
I would suggest to double check the docs again:
https://developers.facebook.com/docs/javascript
https://developers.facebook.com/docs/javascript/examples
In the second link you'll find an example to login a user and then call the API that I believe will be helpful for you.
I hope it helps.
I am very confused.
I created the following script which is located at http://tapmeister.com/test/dom.html. For some unknown reason, tinymce.editors.ta1 and tinymce.editors[0] show up as undefined, and attempting to use a method under them results in an error. But when I inspect tinymce or tinymce.editors using FireBug, I see them in the DOM.
So, I create a jsfiddle http://jsfiddle.net/JWyWM/ to show the people on stackoverflow. But when I test it out, tinymce.editors.ta1 and tinymce.editors[0] are no longer undefined, and the methods work without error.
What is going on??? Maybe something to do with public/protected/private properties? How do I access methods such as tinymce.editors.ta1.hide()? Thank you!!!

TinyMCE doesn't do all of the setup work immediately when you call init. It provides a callback, setup, to tell you when the work is done.
So if you provide a setup callback, you can interact with the editor instance then.
Here's an example (I've also moved your scripts to the end, which is best practice regardless):
Live Example | Live Source
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1" />
<title>Testing</title>
</head>
<body>
<form>
<textarea id="ta1"></textarea>
<textarea id="ta2"></textarea>
</form>
<script src="http://tinymce.cachefly.net/4.0/tinymce.min.js"></script>
<script type="text/javascript">
tinymce.init({
selector: "#ta1, #ta2",
setup: function(e) {
console.log("Editor " + e.id + " is ready");
}
});
</script>
</body>
</html>
Now, if you want to actually access the editor instance, bizarrely TinyMCE doesn't add it to tinymce.editors until after calling the setup function. But if you throw in a brief yield, you're all set. Here's the above with a changed setup function:
Live Copy | Live Source
setup: function(e) {
// Bizarrely, TinyMCE calls `setup` *before* adding
// the relevant editor to `tinymce.editors`,
// so we have to yield briefly
console.log("Editor " + e.id + " is ready");
if (e.id === "ta2") {
console.log("It's ta2, I'll hide it in a moment.");
setTimeout(function() {
tinymce.editors[e.id].hide();
}, 0);
}
}
So why did it work on jsFiddle? Well, jsFiddle has a truly brain dead surprising default setting, which is to put all of your script in a window#load callback function. window#load happens very late in the load process, after all external resources have been loaded. (You can see that in the jsFiddle UI, it's the second drop-down list on the left.) So apparently TinyMCE was completely ready at that point, where it isn't earlier in the cycle.
Side note: 99.9% of the time, there is absolutely no point in supplying a tag name with an id selector, e.g. textarea#ta1. id values are unique, so you don't have to qualify them unless you explicitly want to avoid matching an element that may sometimes have one tag name, or other times have another, which is a pretty unusual use case.
There's a large chance that your script is running before tinyMCE has actually loaded. It might be the case that it loads faster from your test site so that is why it works.
Use as a quick check.
I have been playing around with Scala/Lift/Comet/Ajax etc. recently. I came across a problem which boils down to this:
Summary
I want to update a specific div (by id) when a certain event occurs. If the div does not exist yet, it must be created and appended to the HTML body.
Currently I cannot get this to work when using the Lift framework.
Source File
LIFT_PROJECT/src/main/webapp/static/mouseViewTest.html:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

}
$('#mouse_'+uniqueId).html(coords)
}
// ]]>
</script>
</head>
<body></body>
</html>
The Error
If I open the above file directly in a browser (file:///LIFT_PROJECT/src/main/webapp/static/mouseViewTest.html) it works i.e. a new div is created.
But if I run it through Lift/Jetty (http://localhost:8080/static/mouseViewTest) I get the following JavaScript error:
Chrome:
Uncaught Error: NO_MODIFICATION_ALLOWED_ERR: DOM Exception 7
Firefox (Firebug):
An invalid or illegal string was specified" code: "12
Comparing the Sources in Browser
When comparing the page sources in the browser, I can see only one difference, namely: Lift adds the following JavaScript just before the closing </body> tag:
<script type="text/javascript" src="/ajax_request/liftAjax.js"></script>
<script type="text/javascript">
// <![CDATA[
var lift_page = "F320717045475W3A";
// ]]>
</script>
Questions
Does anyone have an idea why this happens?
If I would want to move the JavaScript code into the Scala file (using Lift's JavaScript and jQuery support), what would the code look like?
Please note: When I used Jq("body") ~> JqAppend() to create new divs, it worked. I just didn't know how to check whether the div id already existed. Thats why I moved the code into the template, planning on using Lift's Call function to execute the JS function. And thats when these problems started...
Thanks!
I recently ran into a similar problem and, from what I've gathered, the problem is because the page when served by lift is served as XHTML and there are some issues when writing to the DOM if the page is XHTML vs. HTML. I don't know whether this is a bug with jQuery or Safari or if it's just something that's not possible in XHTML, but a quick way to fix it is to modify your Boot.scala to tell Lift to not use XHTML as the mime type with this line:
LiftRules.useXhtmlMimeType = false
I have found several other questions here on S.O. (and the web in general) that ask roughly this same question, but the answers always seem to suggest other ways of structuring code that avoid the need for addressing this underlying issue.
For example, many people suggest (and a good suggestion, I agree) to put your code in the jquery load method's callback, on the calling page and not the called page. However I have unique scripts that may appear in certain resources, so I would not want to do that for every load and nor do I necessarily know what these scripts will be.
Here is a test setup to demonstrate what I'm trying to do. The short summary is that when I load partial.htm from main.htm, its script does not fire.
main.htm:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>main file</title>
</head>
<body>
<ul id="links">
<li>some page1</li>
<li>some page 2</li>
<li>some other partial page</li>
</ul>
<div id="panel" style="display:none; padding:20px; background-color:#CCC;">
LOADED CONTENT WILL GO HERE
</div>
<script type="text/javascript" src="/path/to/jquery-1.3.2.min.js"> </script>
<script type="text/javascript">
$(function(){
$('#links a').click(function() {
var $panel = $('#panel');
$panel.show();
$panel.html('Please wait...');
var href = $(this).attr('href');
$('#panel').load(href + ' #content');
return false;
});
});
</script>
</body>
</html>
OK, very simple functionality on this page. Imagine there are many more links, and some of them may require scripting while others do not.
Here is partial.htm:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>partial file</title>
</head>
<body>
<div id="content">
<p>Hey, I am the partial file!</p>
<script type="text/javascript">
alert('I am some JS in the partial file! But sadly I do not execute...');
</script>
</div>
<div>
I am some other content on the page that won't be included by jquery.load()...
</div>
</body>
</html>
Notice that my script in partial.htm does not fire. So, my question remains: how to get this to fire, excluding any answers that tell me to put this in the .load() method's callback. (This would be because I may not have the fore-knowledge of which scripts these partial pages may contain or require!)
Thank you!
Update #1:
I suppose an acceptable answer is simply "you can't." However, I'd like to know if this is definitively the case. I haven't been able to find anything that officially states this yet.
Also, when I use firebug to inspect the panel region afterwards, there is no script element present at all. It is as if it is being parsed out by load.
Update #2:
I've narrowed this down to be a problem only when using the selector as part of the href. Loading the entire "somepage.html" will execute the script, but loading "somepage.html #someregion" does not.
$panel.load('somepage.html'); // my script fires!
$panel.load('somepage.html #someregion'); // script does not fire
I'm going to try and hunt down why this may be the case in the jquery source...
Well it seems that this is by design. Apparently to make IE happy, the rest of us suffer. Here's the relevant code in the jquery source:
// See if a selector was specified
self.html( selector ?
// Create a dummy div to hold the results
jQuery("<div/>")
// inject the contents of the document in, removing the scripts
// to avoid any 'Permission Denied' errors in IE
.append(res.responseText.replace(/<script(.|\s)*?\/script>/g, ""))
// Locate the specified elements
.find(selector) :
// If not, just inject the full result
res.responseText );
I'm wondering if, instead of just stripping out the scripts, I could modify the jquery source to include them in some other way that makes IE happy? I still have yet to find anything else on the web discussing this matter, I'm sure I'm not the only person stumped by this?
I have run across issues before with IE not running injected <script>s that didn't contain the defer attribute. This discussion thread has some good information about the topic: innerHTML and SCRIPT tag
