Dynamically Add (OnKeyDown) Event Listener
May 9, 2011I have a form with many, many, many 'input type="text"' elements in it. I'd like to be able to dynamically add an 'onKeyDown' event listener. Here's what I've got, so far (I know it's wrong.)
Code:
function addEventToElement(formName,tagName,typeName,eventName,eventAction) {
thisForm = (typeof formName == 'string') ? document.getElementById(formName) : '' ;
thisTag = (typeof tagName == 'string') ? tagName : '' ;
thisType = (typeof typeName == 'string') ? typeName : '' ;
thisEvent = (typeof eventName == 'string') ? eventName : '' ;
thisAction = (typeof eventAction == 'string') ? eventAction : '' ;
if(thisForm != "") { // If elements are in a form, make sure ONLY those elements are affected
elem = new Array(); elem = thisForm.getElementsByTagName(thisTag); // array of all items of [tag]
alert(elem.length);
if(thisType != "") {
for(j=0;j<elem.length;j++) {
if(elem[j].type != thisType) { elem.splice(j,1); } // If a type is specified, remove tags that do not have a type attribute
}
}
}
else { // Otherwise, any/all elements in a document/body will be affected
elem = new Array(); elem = document.getElementsByTagName(thisTag); // array of all items of [tag]
if(thisType != "") {
for(j=0;j<elem.length;j++) {
if(elem[j].type != thisType) { elem.splice(j,1); } // If a type is specified, remove tags that do not have a type attribute
}
}
}
if((thisEvent != "") && (thisAction != "")) {
for(i=0;i<elem.length;i++) { // All elements are picked - let's apply some attributes
document.getElementById(elem[i].id).addEventListener(thisEvent,thisAction,false)
}
}
}
HTML Code:
addEventToElement('form_name','input','text','keydown','return numbersOnly(event,this);');
Onclick Event To Call A Function In An External File And Execute It?
Jul 6, 2011I have a few buttons on a page I'm developing and I want the onclick event to call a javascript function in an external file and execute it. I would like to be able to pass a parameter to that function and then either have the function take the user to a new URL or make changes to the webpage content.
Initially (just to test) I had inline javascript that caused an alert to popup. That worked fine. Next I took the inline code and put it in a function in an external javascript file that was referenced in the HTML:

Passing 'this' To Anonymous Function In Event Listener

View 3 Replies View RelatedEvent Listener - Check And Activate Function?
Jun 28, 2010Event Listener. From what I understand it will check all events until a defined event happens, such as rollover of a certain image, and then it activates a function? What I want to do is use this so that when I rollover a element such as below:
<img src="img url" alt="this is a tooltip" tooltip="true" />
I want it to pass the obj to a function which then runs, and then once the mouse of not over that element it will activate another function passing the previous object to this function.
Although an element such as the example below would not activate these functions:
<img src="img url" alt="this is a tooltip"/>
As the tooltip tag does not exist or has the value of false. Also, wouldn't this use a lot of resources as it checks every event which the mouse passes over?
Passing Variable From Event Listener To Function
Nov 5, 2009I need to pass the 'id' variable from the event listener to the callback function, 'moveObject'. The moveObject function needs to know the id of which element it should act upon. How can I pass this variable?

Virtual Point - Redirect To External URL
Feb 11, 2010I am doing a virtual point of sales page. Once the user has paid, he should be readdressed to the original web page. But this doesn't happen. I have realized the payment bank code is window.opener.location='[URL]'. I have copied their code and changed that by window.open ("[URL]") and it perfectly works. I have replicated the situation in these links...
The one that doesn't work [URL]
And the one I have modified and works [URL]
They insist their code is ok. Obviously I cannot modify their code located in their server.

Sep 4, 2010I'm trying to use the addEventListener function to set an event listener but I don't understand why it won't work. Before i was using another method to handle events, but I needed more control over which event handlers get run and when.
Code:

I'm using Google Chrome, but it won't work in Firefox either. Obviously it won't work in IE, since IE doesn't support that method. The script gives no errors at all. The runMe() function does get executed, I tested this with alerts.
Object Method As Event Listener
Oct 16, 2006I want each instance of an object to be able to listen for input events.
When the event occurs, a method of the object should be called, such
that "this" is in scope and refers to the object instance.
Is this possible? Example:
function MyConstructor(element)
{
//element is some HTML element
this.addListeners(element);
this.foo = "Bar";
return this;
}
MyConstructor.prototype.addListeners = function(element)
{
element.addEventListener("keypress", this.doSomething, true);
}
MyConstructor.prototype.doSomething = function(e)
{
alert(this.foo.length); //Error: this.foo has no properties
alert(this);
//shows the HTML element that triggered the event
}
Is there any way to get "this" to refer to the object in the event listener?

Adding Event Listener As Attribute Breaks?
Nov 21, 2011I am testing some code that finds and element and attempts to add an event handler attribute to it as 'onclick' (test case in Firefox 3.5.9)
/*
The actual code is:
window.onload = function()
{
//<irrelevant code>
var test = document.getElementById('tstEl');
[Code]...
I am trying to do this because Element.addEventListener or Element.attachEvent won't allow for arguments to be passed to the event handler code/function. What is going on here? The only line referenced, line35, in the document text containing javascript code is irrelevant to the problem.
