In Javascript, if an object has lots of properties that are functions:
var obj = { foo: function() { ... },
bar: function() { ... },
...
}
then how can you get an array of names of those functions? That is, an array
["foo", "bar", ... ]
thanks.
I can't believe it, but this is really happening. I ran out of available quote symbols using jquery and javascript native functions together. Can somebody help? Maybe there is yet another symbol?
var t=setTimeout('$("#popupChange").html('<img src="http://servername/pdf/picture/genericThrobber.gif" />');',2000);
Hi,
I'm a .NET programmer who've just started to learn more about client side scripting, and I was wondering sometimes you use $get('value') and $find('value') and I've discovered that these are just shortcuts for document.getElementById('value') and Sys.Application.findComponent('value'), respectively.
However, I still don't understand: what is the difference between these two functions in JavaScript? What exactly are they looking up/retrieving when invoked?
Thanks in advance.

Let's say you have a Javascript function that calls a web service method. So that webservice completes and calls a callback function, which has the result.
How do I get that result back into the original function that called the web service method? Essentially, I'm trying to "synchronize" an asynchronous call.

I have this method for downloading a script:
var script = document.createElement('script');
script.setAttribute("src", url);
document.getElementsByTagName("head")[0].appendChild(script);
This gives me a GET like this:
GET http://127.0.0.1:17315/Scripts/abc.js HTTP/1.1
However I need to add a header:
Authorization: Bearer Ipnsfm9h1MWYIM0n1ng
Can anyone tell me how I can add a header when I am using Javascript to perform the GET?
I have a custom control and I am trying to validate a hidden field. The validation works fine but I am getting the following Javascript error every time (output from Firebug):
Error: element is null
Code: var currentClassName = ' ' + WebForm_TrimString(element.className) + ' ';
URL: http://localhost:58462/WebResource.axd?d=...
The following does not work:
var js_str= '<?php echo $str_from_server; ?>';
The problem is that, $str_from_server can contain any characters. If it contains single quotes or line breaks or others, the above code will break. And I do not have access to the server-side code. What's the easiest way to "escape" the contents of $str_from_server into a javascript string, and then it can be restored later?
