need to call two functions say func1(a,b) and func2()i used the following code. But only the first function works, second one not working
Code:
<input type="button" value="Start" onclick="func1('A','B');func2()">
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?
This button changes the button text when clicked, but it is always calling the same function. How to make the button depending on the button text to call different functions on onclick?

I am trying to create a script that will cover cross-browser limitations in adding event listeners to elements. I have found plenty of resources to add a listener but can't find any way of assigning a function containing arguments. Here is what I have so far:
/* Attach events regardless of browser */
function addEvent(obj, evType, fn)
{
if (obj.addEventListener)
{
obj.addEventListener(evType, fn, false);
return true;
}
else if (obj.attachEvent)
{
var r = obj.attachEvent("on"+evType, fn);
return r;
}
else
{
return false;
}}
/* Contains all attachments to be made on page load */
function load()
{
item = document.getElementById('toggleControl');
addEvent(item, 'click', toggle);
item = document.getElementById('alertLink');
addEvent(item, 'click', runAlert);
}
/* Add event to page load and assign load() function */
addEvent(window, 'load', load);
The actual functions for toggle and runAlert are in a seperate .js file, but are standard functions. the problem is that I can't find a way to perform the equivalent of:
item = document.getElementById('toggleControl');
addEvent(item, 'click', toggle('toggleID'));
It simply does not work.
I have several form in my site, that validate on onsubmit.I call all the validation functions from a file call functions.js.Here is a sample of the code that is working:
<form name="contact" action="contact-insert.php method="post" onSubmit="return checkform()">
<label class='SubHeadlbl' for='TextField1'><?php echo IDS_EFORMNAME?><br></label>
<input type='text' name='dfname' class='text_field' id='dfname1' size='70' maxlength='40'/>
</form>
all the other forms are not working. all have the same structure:
<form name="frm1000" action="frm1000-insert.php method="post" onSubmit="return checkform1000()">
<label class='SubHeadlbl' for='TextField1'><?php echo IDS_EFORMNAME?><br></label>
<input type='text' name='dfname' class='text_field' id='dfname1000' size='46' maxlength='40'/>
</form>
I don't know what is happening only one for work all the others don't.
So in the Tutorials:How jQuery Works, I've noticed that you can make a call to .get like this : $.get('myhtmlpage.html', myCallBack);
I've also noticed that in the docs jQuery.get() is described as jQuery.get( url, [data,] [success(data, textStatus, jqXHR),] [dataType] ). My question is, in the above example, the callback function is the second argument, whereas in the docs the second argument is data, and the third is the callback function. How does this work? Also, what does it mean when the arguments are laid out in an array-like fashion with commas in the square brackets? i.e. arg1, [arg2,]...
I encountered some code in "Javascript the good part" from Douglas Crockford.There is a way to passing callback function as second argument to string.replace() method.
Code:
var entity = {
quot: '"',
lt: '<',
[code]....
1. How do I know what the number of parameters should be in callback function ( function(a,b) ) ?
2. How do I know what will be passed in as a and b when I am defining the callback function?

Im trying to write a code to draw random numbers, like a lottery generator. It will require the user to input amount of numbers per line & choose the amount of numbers. From the numbers the user inputs it will generate random numbers to that guideline.
I have wrote the random number function, that works fine. Im having problems invoking it with ONCLICK event handlers. I cant seem to get the correct arguments. And all i get in return is "undefined"
This is the form for the onclick button
<INPUT TYPE = "button" NAME = "drawBalls" VALUE ="Draw the Balls!"
ONCLICK = "lotteryForm.drawnNumbersTextBox.value = ">
Now Im not putting up to much code, as its part of an Assignment, I dont want to cheat, i just want to be pointed in the right direction. :(

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);

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.

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.

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?

Ok, so basically what I've got is a button which when clicked, "opens" a section of the page. I also need the button to "jump" to this section of the page, because it's below the current content and won't be visible. What I've got so far is ...

The context: I am trying to fire a Google Analytics Tracking Code, and a Website Optimiser Conversion Script on an Onclick, one after another, before following an external link. It's on an image button. It must work for JS disabled. The Problem: The first one was that the newest browsers were executing the external link before the tags were firing. I added return false; to stop this which it did. This however ignited an old problem I had - being the two scripts just would not fire one after another. The Code:

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:
