Is there a way to pass arguments to the callback function used inside an addEventListener? I see that I can only list the name of the callback function. For eg, I use this:
var boldLink=document.getElementById('cmtbold');
boldLink.addEventListener("click", rBold, true);
I need the id of boldLink to be accessible from inside the function
rBold()
Every time i click on one of the said elements, it puts "undefined" into the textbox each time i click on an element.it seems to me that the Key_Table[x] is not getting passed correctly. How do i make sure that this is getting passed correctly?Here's my Code:
<script type='text/javascript'>
// Startup Script
if (document.addEventListener) {
[code].....
What I want is a loop that will call the same function until it reaches a certain number (let's say 10). Then I want the function to take the parameter passed (the number) and use it in the function where ever you see a 1 below. Basically I want it to run on each element of the pub_name array and from the info gathered define a variable based on the number (example: display_pub_name_*). I have run some tests .....

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 use addEventListener and I cannot (or at least don't know how) pass arguments to the function.
Let's say we have a function:
function warning(arg1, arg2) {alert('Argument 1: ' + arg1 + ', Argument2: ' + arg2 + '.');}
It's possible to have:
onclick="warning('my argument 1', 'my argument 1');" as an html attribut.
But I think it's not posible to do it like this (still the same function):
el.addEventListener("click", warning('my argument 1', 'my argument 1'), false);
So how can I pass arguments to the function?
I can't seem to get a variable declared from within a post callback, so that I could manipulate my script accordingly. I have delete.php, that deletes an id from a mysql db. If it fails, I want the script to stop and display the error. The .php script echos an "ok" if everything went fine, if not - it echos the error.var abort_error; // set the error variable
$.get("delete.php", { delete: $(this).parent().parent().parent().attr('id') },
function(data){
if(data != 'ok') {

Is it possible to access the data arguments that are sent with the ajax function? Example:
$('#mycheckbox').click( function() {
$.get( '/ajax.php', { nr: this.id }, function( data, textStatus ) {
// Here I want to access the arguments I just sent with ajax.php
[Code]....
I could easily do $('#mycheckbox').attr('checked', 'checked'); but that is not what I want. Also I don't want to send the arguments with the response. Anyone knows a solution? I can't find it in the documentation of jQuery and not in the discussions here.

edited: the first alert has this in the brackets: &l t; i.e. the html code for < but for some reason this foum converts it. and i thought html was off?
I was expecting the above to alert the text in the brackets exactly as written in the code for both divs. However both events alert '<'. Why is that? I want to be able to pass '<' as an agrument to events without being converted, because that is what is happening. How may I prevent it?
I was using this script to learn how to use event listeners and I need to know how to make it work for IE. I keep finding attachEvent scripts that look like they will work, but I get nothing. I've spent several hours finding script after script that simply don't work. I don't know where to turn next. Any script to attach these events to IE?

I am writing a small module which will have several different aspects to it, all based around ajax calls. I want to allow the main ajax functions i.e beforeSend, success, complete etc (I am using jQuery) to be customizeable.I currently have an options object in the module which can be extended with an options object passed to an init function. In here, I am passing a 'callbacks' object with nested ojects for each different type of action as in...
var insertCallbacks = {
before : function() {

success : function() {

I have got a following function:
PHP Code:

if (obj.addEventListener)

for some time I always found a workaround for this kind of problem. But somwhow, it feels wrong. So I'd like to know, if there's a common way to solve something like this[code]...
I'm defining the function and if the value of 'obj' hasn't until the function really gets called, this can work. But it just feels so wrong do have always global variables just to access them inside of a callback.[code]...
Code:
function BaseController(el) {
var that = this;
this.defaultAction = function() {

What is the proper method here so that el will be defined in the super "class".? I know I saw something on stack overflow a couple of days ago but can not seem to find it again.
admin: Something is up with the code tags, why the system is double posting the code. Does HIGHLIGHT=JS not exists anymore? – That seemed not be working.
I know in different languages (VB.Net,C++,C#) how to pass an argument to function in this code:
<html>

<!-- hide
function openNewWindow() {
popupWin = window.open('[URL]',
'open_window',
'menubar, toolbar, location, directories, status, scrollbars, resizable, dependent, width=640, height=480, left=0, top=0')
} done hiding -->

<a href="javascript:openNewWindow();">return to front page</a>

I need to add several links in my page, so I need to pass indexes from links to main function, so I can open images in specific folder with indexes filenames. For example in vb
Subname("text_to_pass_to_SubName")
Public Sub SubName(ByVal function_text as string)
End Sub
I have a main page that opens a pop up window when the user clicks a
link. The pop up window is a menu and when the user clicks the item, it
populates a form input element on the 'parent' window.
My question is: this new populated form element is the value that I use
to change a style.
onchange does not watch this form element because of getelementbyid, so
it doesn't trigger the function needed to change the style. onchange
works fine if I just manually input a value into the text box.
Any other way to fire the function off when the user picks their
selection from the pop-up window? I was thinking I could use
window.opener.function()? But how do I pass the form from the parent
window? From the pop up window, I don't use this.form, what do I
use?something like window.opener.form[0] ?
I tried a function like that
function (test) {
var a=document.form.test.value;
}
test is the name of text fields. I doesn't work (undeclared test variable)
I have an external javascript file with certain attributes defined to open a file in new window, which I use for viewing maps. However I need to define different attributes for the height and width, as I want users to open video clips in smaller windows. What do I need to do? Code:
View 5 Replies View RelatedHow can I create a function that takes optional arguments?
View 7 Replies View RelatedI have a function which can be called with an unlimited number of
arguments.
I want to call another function with exactly the same arguments. I know
I can get the arguments in the arguments object, and as such also in an
array, but how do you pass the elements of an array to another function
as parameters?
Sorry, bad title. Anyway, is there a way to pass the arguments to an object
instantiated via a constructor using the arguments object and have it
expanded, so to speak, so that it doesn't appear as a single argument? I'm
sorry, this explanation is just atrocious, but I can't think of exactly how
to word it. Maybe an example...
Take for instance Function.apply. It takes 1-2 arguments, the first being
the object to use as the context, and the second being either an array or an
instance of the arguments object which are to be the arguments for the
function. I want to do something similar but I want to also basically use
the new operator so that I get back an object.
Here's a snippet of some of my code, maybe this will help:
