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:
<!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">

<script src='http://connect.facebook.net/en_US/all.js'></script>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<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'm working on a JAVA web application which plays the role of a search engine. Its backend is developed with AngularJS. And I have a small PHP code which tries to send a data from an input text to the JAVA web app via an iframe. the data is stocked in a localStorage.
Here is below the PHP Code :
index.php
<!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>
<title>Search</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<script type="text/javascript">
function redirect(){
var toSearch = document.getElementById('wordToSearch').innerHTML;
console.log("toSearch : ", toSearch);
localStorage.setItem('wordToSearch', 'bdd');
window.location.href = "http://localhost:8050/searchEngine/#/search";
}
</script>
<form action="http://localhost:8050/searchEngine/#/search">
<input type="text" name="word" id="wordToSearch">
<input type="submit" value="Search" onclick="redirect()">
</form>
</body>
</html>
Precisely, I'm trying to retrieve the "wordToSearch" item value stored within the localStorage
Here is below the code where i add my iFrame to my application :
<iframe src='http://localhost:8040/test/index.php'></iframe>
This is the result i get in the developer tools :
Developer Tools Result
Can anyone help me please ?
So TL;DR, you're saying you want JavaScript code running on a page whose origin is http://localhost:8050 to access the localStorage for origin http://localhost:8040 (or vice-versa)?
You can't do that. Web storage is specific to the origin, which includes the port.
You can do it using cookie, set value to http://localhost:8050 and get value from http://localhost:8040. Visit https://developer.mozilla.org/en-US/docs/Web/API/Document/cookie
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">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>SiteMap</title>
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" />
<style type="text/css">
</style>
<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 ;)
}
//-->
</script>
</head>
<body >
<form action='' method='POST' enctype='multipart/form-data'>
<input type='file' name='userFile' onchange="OK()" id="dialog">
</form>
</body>
</html>
and file2.htm:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>SiteMap</title>
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" />
<script type="text/javascript">
<!--
var NameSpace1;
function modifyMyName(){
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 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
JS Fiddle:

I've found various ideas on how to detect when a web video ends, but can't get the syntax right for the way I'm using javascript to play the video. Note that I'm using version 4 of the jwplayer.
Here is the HTML that uses swfobject.js and player.swf. It works fine, but I want to add code that detects when the video has finished at will then redirect to a web location using - window.location.href = http://www.webpage.com
Any help will be very appreciated! Here's the full page of HTML code:

<p id='preview'></p>
<script type='text/javascript'>
var so = new SWFObject('player.swf','player1','640','381','9');
so.addParam('allowfullscreen','true');

You need to use our JS API - http://www.longtailvideo.com/support/jw-player/28851/javascript-api-reference
And, use our JW Embedder (Not SwfObject) - http://www.longtailvideo.com/support/blog/15827/using-the-jw-embedder-to-embed-your-player
Then, the set up will look something like this:
<h2>Redirecting on complete</h2>
<div id="container">This'll be the player</div>
<script type="text/javascript">
jwplayer("container").setup({
file:"bunny.mp4",
flashplayer:"player.swf",
height:400,
width:600,
events:{
onComplete: function() {
window.location = "http://www.google.com";
}
}
});
</script>
Hope that 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!!!

<script type="text/javascript">

console.log(tinymce);

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.
