How can I call functions from the value of a variable?
I do this in PHP, like $variable(); or {$variable . 'CallBack'} or using something like call_user_func().
I've been search all day though, and can't find how to do this in javascript. Is it possible?
I'm sure it's just a syntax problem. You can ignore most of this function because most of it works. The part I'm asking about is the "coordinates" variable 4th line from the bottom. The "office3" variable is a dynamically populated office number. I have the office numbers all defined as variables somewhere else but since I can't just name the variables as numbers I had to put a $ in front of them. Basically I'm trying to call the office number variable, $1656 for example. So "coordinates" is meant to be equal to "$+the chosen office number".[code]...

I want to know if there is a way to return ajax call as html value and not plain text, ie all html formatting will be displayed.
My code:
<script src="jquery.js">
<script>
$(function()
{

String returned from webform4.aspx is html formatted but jquery displayed it as plain text. Is that anyway to display it as html string ?
I have made a basic form, and I need to combine three values within my form, then create an md5 hash of this string.Then assign it to a hidden variable.My form is here...
Code:
<p>
<label for="firstname">First Name: </label>
<input id="firstname" type="text" name="firstname" /><br />[code]....
Or I have created a pastebin of it here, for easy reading: http://pastie.org/1171757.So I need to be able to combine the three values into a string, create a md5 of the string, then call the value of the string into a hidden value all before posting the form.
a.) specify two parameters for the changeYear function: today and holiday.
function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.
I have a for loop: Code: for( var i = 0; i < aInput.length; i++ ) I want to use this i variable to concatonate it as a string to find an input box
Code:
var j = i;
var qualname = "discountqualifier" + j;
qualname.toString();
if ( inputName == ( qualname ) )
{
Assuming I have a input box named discountqualifier0, discountqualifier1, discountqualifier2 etc...
I am writing a simle extension on Google Chrome. But chrome's extension API is not powerfull enough for my extension because i need file io operations for local files. That's why I need to call functions from dll which i write from javascript.
<script type='text/javascript' language='javascript'>
var obj = new ActiveXObject("plugin_proxychanger.dll");
var vResult = obj.plugin_header_class.plugin_header_func_read(3);
document.write(vResult);
</script>
I get this error on every browser: ReferenceError: ActiveXObject is not defined I research it on google and some users told me that i need to write a COM dll. But my dll is .net(2.0) because I don't know how to create a COM dll with Visual Studio 2010.
I am simply trying to use a global variable in javascript, but can only access the variable on the second call. I can't find anything that relates to this through my searches. My application is supposed to query the server for XML that tells me which years and months are available to put into combo boxes. I want to store this xml in a global variable to access it later.

what's the correct syntax to call 2 functions from an onclick attribute? the code below doesnt work, maybe im putting semi colons in the wrong place? since the second function needs the return false, im guessing i should put that one last since return false would stop anything after that from running.
Code:
<a onclick='return confirm("are you sure?"); some_function(param1, param2 ); return false;'>test</a>
am i on the right track?
I want to find out what is the file name of the page that a user is currently viewing (for e.g. the file name of the page where I am composing this query currently is newthread.php). If the file name is Edit.asp, then do something else......this is the
(this is the onLoad event function)function getFile(){
var strURL=window.location
//since the file name will be at the end of the URL, I am using
//a negative number as the start parameter in the substr function
if(strURL.substr(-9,strURL.length)=="Edit.asp"){
//do something
}
else{
//do something else
}
}
But the above doesn't work. In fact, some of the JavaScript string functions I tried (like match, length etc.), none of them seem to work since the string has been derived using window.location. Why? Doesn't JavaScript consider the URL of a page as a string object?

Firstoff: I know I ask about using a plugin, and I wasn't so sure where to put my question in, decided though the general jQuery-Forum would be better as my problem is more connected to jQuery than the plugin itself. First off, I'm using this plugin and modified it myself a bit, adding new functions: [URL] You'll find the underlying .js for the component here: [URL] Now, scroll to the end of the file, you'll find some "internal functions" like _registerRemoveEvents

My javascript quits working when I am rendering the html? (It works perfectly fine if the page is opened from http address directly). I did some research and concluded that "JavaScript is executed on page load", so when I render my html, my JavaScript functions are not automatically called.how should I call the javascript functions manually?

Is there a way to call javascript functions based on the text between a span element? In other words if I have <span id="mySpan">Bronze</span> then it will call a javascript function but if I have <span id="mySpan">Silver</span> then it will call a different function?

I have a web page that has a short flash show on it, then it redirects to the main site index page, using a setTimout in body onload. That was all working fine. Now I need to add an OS detection function to redirect iphone and ipad users immediately (bypassing the flash pape). So, I have 2 functions that need to be in the body onload. I figured the logical thing to do would be to write another function that calls the first 2, then put that one in the onload. But now nothing is working. I have played with in for an hour with no luck.
Just as a note: Original, before I had to add the OS detection, there was just the delayer function, and it was called thusly:

My problem is that every other turn I have to click either button twice to start the desired function. Say, I autoplay the images first and I want to shuffle them, I click shuffle and the autoplay stops working and I need to click shuffle again and then the shuffle runs. How can I make it clicked once and the function runs?
I have a problem that 'test' is not passed. The following function alert undefined, but it should alert test. Why that?
PHP Code:

}
function(something) {
