if(document.getElementById('featuredmedia'))
{
var fmElements = document.getElementById('featuredmedia').getElementsByTagName('li');

I totally understand that in order to learn javascript I need to know how functions work, I understand the basics of passing in parameters and then calling the function with the values to maybe add something together etc I ve read countless articles about functions as well as books etc but I just dont get how they are used and when they should be used etc, the more advanced functions that have maybe 4 parameters and are doing different calculations and returning various values that get fired back into the script just totally confuses me.
What I would like to know is first of all how can I overcome this confusion and also any words of wisdom you may have. I will also add that I have no prior programming experience and have spent the last 2 months frequently hitting my head off a brick wall as I just cant understand javascript.
I might register an event like this:
var a = document.getElementById('elementid');
a.onclick = doSomething;
To keep the function from firing at registration, I assign 'a.onclick' to doSomething rather than doSomething(). Suppose the event I want to fire requires sending parameters to the function doSomething()? How can I send the parameters?
I have some jQuery.ajax() calls. It'is all the same but success function and I'd like get less code by taking all ajax calls in the same function.But I need one additional parameter I am using later in the success function, for instance.My actual code is like this:
jQuery.ajax(myParam){
...
success: function(responseData){[code]....
But I can't manage to archieve that.

I have a form button with id="submit". When pressed, ClickGeocode(credentials) is called. This works fine and dandy with: $('submit").click(ClickGeocode) Despite there being no indication that the function takes an argument 'credentials'. So when I want to call the function at some point in my code, I should be able to do something like ClickGeocode(credentials) ... no? However, my issue is that credentials isn't once defined in my code - it is part of Bing Maps function... like so:
function ClickGeocode(credentials)
{
map.getCredentials(MakeGeocodeRequest);
}
So why does it work using .click(), and how can I call the function without user interaction (simply somewhere in my code) even if 'credentials' is not defined?
I'm relatively new to JS, but I have some experience with ActionScript. Can anybody explain this to me:
I define a function:
function myFunction () {something.....;}
And then I want to call it by a event handler:
document.onmousemove = myFunction();
it doesn't work. Why?
I know, that the correct syntax would be:
document.onmousemove = myFunction;
WITHOUT ANY PARAMETERS. Why is this correct?
And how is it possible to pass any parameters to my function (if it was pe.: myFunction(someParameter) {blabla.....;}
There are basically 4 fields in a form, being Name,Company,Email and Phone. I'm trying to use the ONBLUR event, on the email field, to then pass parameters to a JS function, which calls a PHP file, to insert a row into a MySQL db. I saw an example of how to do this, using a hidden field, possibly I need 3 hidden fields to pass the 3 parameters (value of fields) ?. Anyway, here is the code:

I keep getting a runtime error stating that this
document.adddealer.dealertoadd.value = dealer; is null or not an
object. I've rewritten the Function everyway I could think of, and
couldn't find any thread examples of my problem.
Here is my Function;
<Script language="JavaScript">
<!--//hide
function AddDealer(dealer) {
document.adddealer.dealertoadd.value = dealer;
document.adddealer.submit();
}
//-->

This calls the Function;
<input type="button" value="Make This My Dealer"
name="button">

I am having one td and inside td using one control(it may be any control like textbox,combobox) and am using onblur events for td and aswell as the control inside td. when am moving focus from this td to another td the parent onblur event is firing first and then child control(like textbox, combobox) onblur event is firing. The problem is am validating that entire td (what ever the value user updates) in one method. so in this scenario that validate method is calling when i move the focus onto child control. After entering the value in the child control that child control onblur event is firing and am unable to fire the parent control(td) onblur event.

I tried to replace show(100,flo) with show(100,flo(zahl,r_g)) but then the divs only move from a to b but even will not come back to a again. I think the solution should be pretty simple but i cant figure it out.

View 2 Replies View RelatedI want to attach a js function to be called when a img is clicked and I'm changing the functions of onclick based on the image. I used setattribute but it doesn't works in IE. So I decided to use
object.onclick = somefunction;
but my functions are based on parameters and the whole function runs based on the passed parameter.
So I tried:
like this object.onclick = "somefunction('"+mat+"')";
but doesn't work. I need a code which can attach the function on click event for both firefox and IE.
Problem: I have two functions that send an AJAX call via an attached .js file (engine.js) and then deal with the response. My problem is this, the function can be called by any number of different triggers and needs to pass the data to a different element depending on which one calls it. These different triggers are produced via a repeating region created by Coldfusion. Each element that can get acted upon by "updateImgCount_response" is named "imgCount[recordID]" where "recordID" is a value inserted by coldfusion. This way each Element has a unique ID. Now I just need to know how to tack the "recordID" value returned as part of "obj" onto the 'imgCount' in document.getElementById() the updateImgCount_response function. Code:
View 1 Replies View RelatedI was reading through a book that talked about unobtrusive javascript, and it gave this example of how to trigger a function instead of using an inline onmouseover event handler.
document.getElementById("RandomElementId").onmouseover=RandomFunction;
I thought this would be cool, but I can't seem to find a way to pass parameters to the function this way. I assumed you just use RandomFunction(parameter1,parameter2); but no go.
Is there a different syntax for this, or does this technique forbid using parameters?
I have 2 javascript files: 1 containing generic functions for my site used sitewide and another for a particular web page containing just the javascript for that page. The page is also calling the jQuery javascript file.
What I want to do is have a javascript function in my main javascript file which uses features of jQuery such as show, hide etc. and then I want to call this javascript function from the other page specific javascript file.

I try to make something where you add elements, and can delete elements later by calling a simple function.

I am trying to call 2 functions from the 1 onMouseOver event on an
anchor tag, but I can't seem to get it to work. the following should
demonstrate
<a onMouseOver="ShowMenu('Menu3');AddMenuToHoldArray('Menu3')">Menu
3</a>
I have tried a number of variations, like adding "javascript:" in
front of the first call, and returning True of False from the first
function, but Icant get the second function to fire after the first
one has.
by using alerts, and wathcing what IS occuring, I know that the first
is being called, but the second isn't.
I did this once some years back, but I can't seem to rember how I did,
it, and none of the example that I have located have helped, so can
anyone point me in the right direction?
Trying to figure out what was happening in a snippet in the jQuery docs. The snippet I refer to is here , documenting event objects.
The code:
Has me a tad confused. I know that e is an event object that calls keydown event for keycode 64 but what I am unsure of is how it is being triggered. There is no context to it, if you use .trigger() that way is the event called upon the loading of the object? If not when is .trigger() being called?
