EDIT: I have discovered that this is a 405 error. So there is something going on with the webserver and handling POST methods.
I am having a strange occurrence. I have identical javascript code on both my test environment and production environment.
The test environment functions, and the production does not. Here is my identical code.
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" src="http://cdn.jquerytools.org/1.1.2/jquery.tools.min.js"></script>
<script type="text/javascript" src="./js/jquery.scrollTo-min.js"></script>
</head>
<body>
<div class="content" id="content">
<a id="changeText" href="test.html">Change</a>
</div>
<script>
$(document).ready(function() {
$("#changeText").live('click', function(){
var url = $(this).attr("href");
$("#content").load(url, {var1:Math.random()*99999},function(){
alert(url + " loaded");
});
$.scrollTo("0%", 400);
return false;
});
});
</script>
</body>
</html>
Both environments report that
alert(url + " loaded");
is happening. But only my test environment actually displays the change.
The production webserver has "test.html" available in the correct location.
Are you sure the scrollTo script is being included on the production server ( or am I misinterpreting what you mean by change ) ? Perhaps try a root relative path instead of './js'? I would check Firebug's script tab to ensure it is being included.
405 errors mean that the URL you're sending to isn't expecting you to send the data in that manner. For example, if you're sending a POST request to a URL that's only designed to handle a GET request, you'll get this error.
My guess is whatever server you're running on is set up to not allow POST data to be sent to a page with a .html extension, causing the error you're seeing. Try changing the extension to a .php, .aspx, etc, and see if that helps.

Given the following document, Require.js functions fine if I run it on a webserver but fails if I open the same document locally (file:///).
I'll see 'called' printed to the console when I open the document locally (thus callback fired w/o issue) but:
There is no request listed in Firebug's/Chrome's network tab.
The variables in common.js aren't defined and none of the console.log statements run.
Require.js is NOT requesting the common.js file when the document is loaded from my desktop.
<html>
<head></head>
<body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script src="https://s3.amazonaws.com/<MYBUCKET>/scripts/require.min.js"></script>
<script>
require.config({
baseURL: 'https://s3.amazonaws.com/<MYBUCKET>'
});
require(['scripts/common'], function(){
console.log('called')
});
</script>
</body>
</html>
Given that baseurl states the http/s protocal, I don't understand why this is failing when the document is located on my desktop and works fine when the document is located at http://whatever.com.
Secondary/related:
Ideally I'd like to omit the protocals and allow the browser to handle that itself but this of course also fails completely locally.
(same code as above, sans http/https)
<html>
<head></head>
<body>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script src="//s3.amazonaws.com/<MYBUCKET>/scripts/require.min.js"></script>
<script>
require.config({
baseURL: '//s3.amazonaws.com/<MYBUCKET>'
});
require(['scripts/common'], function(){
console.log('called')
});
</script>
</body>
</html>
This probably has nothing to do with Require.js and everything to do with how browsers handle requests from file:
Is there a sensible way to make this work regardless of the document's location?
It's baseUrl, with only the U in capitals. You're using baseURL which is ignored.
I am having difficulty with a specific JQuery $.post call to a PHP-based processor. I created a test page with the code below located here: http://goo.gl/Bg7H2u
Note this is located on a subdomain, but we are not doing cross-domain posting. Everything should be included on the subdomain.
There do not seem to be any JS errors as reported in the error console.
The processor /get-data.html is the general purpose PHP processor, and, if you load the processor page with the right value, it returns a dataset from the MySQL database in JSON format. We have this working on the main domain without issue, and other $.post calls seem to work OK from this subdomain (not to this /get-data.html processor, but other processors that process form content).
See the actual processor output here: http://goo.gl/yOzrm2
I must be missing something obvious, but I am coming up empty. Thoughts?
Here is the code:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=320px, initial-scale=1">
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
var prices;
$(document).ready(function(){
$.post( "/get-data.html", { table: 'prices' },
function( data ) {
prices = data;
alert(prices);
}, 'json');
});
</script>
</head>
<body>
<div style="overflow-x: hidden;" id="divMain">
</div>
</body>
</html>
Thanks for any advice you can provide.
If you do View Source on the processor output, you'll see that your script is returning:
<p>{"Basic Plan":["349"],"Basic":["349"],"Premium Plan":["549"],"Premium":["549"],"Standard Plan":["429"],"Standard":["429"],"Bonus Plan":["175"],"Additional Central AC System":["99"],"Additional central heating system":["99"],"Central Vacuum":["99"],"Whole home humidifier":["49"],"Pool (in-ground)":["179"],"Spa (in-ground)":["179"],"Septic System":["99"],"Sump Pump":["99"],"Well pump":["99"],"Whole home water softener":["99"],"Lawn sprinkler system (in-ground)":["99"],"Wine refrigerator":["49"],"Ice maker (free standing)":["49"],"Home phone (unlimited)":["49"],"TV Protection (Flat screen up to 60 inches)":["99"],"PC Protection (laptop or desktop)":["49"]}</p>
There's <p> at the beginning and </p> at the end. This is not valid JSON. You need to fix the server script so that it doesn't print anything other than the JSON (whitespace is OK, that's it).
1.confirm that /get-data.html is the correct relational url for your file location.
If you navigate directly to the /get-data.html, does it produce the results that you are after.
try running the same code without , 'json' and see if it works.
hope this helps
I am new to the world of JavaScript and I'm trying to use the function load() to insert another html file. It' a little bit hard to explain, here is the code:
<script>
$(document).ready(function() {
$('#main').click(
function(){
$('#news').load('today.html');
}
); //end click
}); //end ready
</script>
Can you help me? I'm not using a web server.
Thanks
Why it Doesn't Work
Browser security restrictions can block you from using AJAX functions with content that is accessed through the file:// protocol (i.e. from a local file on your computer, without a web server).
Solution
I run a web server on my pc so that I can avoid all of these problems - back when I was working on a Windows PC, I used WAMP. These days, I use Linux (with Apache, PHP and MySQL) on my computer so I can work in an environment that is closer to the server.
I do not believe the code you have presented has any faults in any way. I believe it is to do with your loading of the JQuery library, as with the following code I achieved these results:
index.html
<html>
<head>
<script src="jquery.js"></script>
<script>
$(document).ready(function() {
$('#main').click(
function(){
$('#news').load('news.html');
}
); //end click
}); //end ready
</script>
</head>
<body>
<p id="main">HELLO</p>
<p id="news">NEWS</p>
</body>
</html>
news.html
<html>
<head></head>
<body><h1>HELLO STACK OVERFLOW!!!</h1></body>
</html>
Before click:
After click:
However, when I was building this example I first tried using the Google APIs version of JQuery and found that I could not currently connect to the API. Therefore I believe the solution to your problem is to go to this website: http://code.jquery.com/jquery-1.11.1.js and copy and paste everything into a text file called 'jquery.js'. Then add the following to the head tag of your main HTML file:
<script src="jquery.js"></script>
Make sure that 'jquery.js' is in the same directory as the main HTML file of your project otherwise this will not work. Hope this helps :)
You can find error message in load(url,fnResponse) response is success or fail
also check this jquery-load-method
$(document).ready(function() {
$('#main').click(
function(){
$('#news').load('today.html', function( response, status, xhr ) {
if ( status == "error" ) {
alert( "Sorry but there was an error: " + xhr.status + " " + xhr.statusText );
}
});
}
); //end click
}); //end ready
I mentioned i read the suggested link ...and Could not able to understand the
suggestion .."Use Greasemonkey to modify Pages and start writing some

I am loading a text file with $.ajax. When running the code on Firefox, I get the following error:
Error: ["Access to restricted URI denied" code: "1012" nsresult: "0x805303f4 (NS_ERROR_DOM_BAD_URI)" location: "<unknown>"]
Here's my code:
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>
<script language="javascript" type="text/javascript">
$(document).ready(function () {
$("button").click(function () {
$.ajax({ url: "demo_test.txt",
success: function (result) {
$("#div1").html(result);
},
error: function (abc) {
alert(abc.statusText);
},
cache:false
});
return false;
});
});
</script>
</head>
<body>
<div id="div1"><h2>Let jQuery AJAX Change This Text</h2></div>
<button>Get External Content</button>
</body>
</html>
I've already read the following questions:
firefox reading web page from local JS file -- access to restricted URI denied, code: 1012, nsresult: NS_ERROR_DOM_BAD_URI
Error: [Exception... "Access to restricted URI denied" .... while calling $.ajax method
It was suggested that file system should not be used, so changed the URL to http://demo_test.txt, but that did not solve the issue.
I also heard that it might be because of a cross domain issue. If so, what exactly is meant by that, and how should I solve the problem?
Browser security prevents the code from running. You are better off running a local server such as IIS or Apache.
You can change your browser to run local content by changing a browser config
Firefox
Go to about:config
Find security.fileuri.strict_origin_policy parameter
Set it to false
I finally seems to Get it working . Here is working Script
$("button").click(function(){
$.ajax({url:"http://localhost/demo_test.txt",success:function(result){
$("#div1").html(result);
}});
});
Workaround : put the html file and text file on local server (IIS) New Site .
I am trying to call a javascript function defined in a parent from a child window. I have two files like this:
Parent:
<html>
<head>
<title>Test</title>
<script type="text/javascript">
function foo () {
alert ("Hello from parent!");
}
function doStuff () {
var w = window.open("testa.html");
}
</script>
</head>
<body>
<input type="button" value="open" onClick="doStuff();" />
</body>
</html>
And child:
<html>
<head>
<title>Test A</title>
<script type="text/javascript">
function get() {
window.opener.foo();
}
</script>
</head>
<body>
<input type="button" value="Call Parent" onClick="get();" />
</body>
</html>
I can not, for the life of me, call the function foo from the child process. I thought this should be possible with the window.opener object, but I can not seem to make this work. Any suggestions?
Ensure you are accessing this via http:// so the Same origin policy passes and you can access opener from the child. It won't work if you're just using file://.
Answering Rahul's question:
Every browser can load pages from server or from local filesystem. To load file from local filesystem you should put to the browser the address like this file://[path], where [path] is the absolute path to the file in filesystem (including drive letter on Windows, see http://blogs.msdn.com/b/ie/archive/2006/12/06/file-uris-in-windows.aspx for details).
To load file from local HTTP server (if you have one) you should put to address something like this http://localhost:[port]/[path], where [port] is the port where your server is running (default is 80) and [path] is the path of the file relative to the server's document root folder. Document root folder depends on the server configuration.
So, as you see, the same local file can be loaded to the browser in two ways. There is however big difference between these two ways. In the first case the browser doesn't use HTTP protocol to load the file and therefore is missing many things necessary for different mechanisms to work properly. For example AJAX doesn't work with local files, as HTTP response status is not 200, etc.
In this particular example the browser security mechanism didn't get the origin information and was preventing from accessing the parent window.
