Hi have an event called function allownumberonly(evt);
My html text input onkeypress calls this function.
onkeypress=allownumberonly(event)
I want to create a text input dynamically and set its onkeypress event
to the above function also passing the event.
look at this script :
$(function(){
$('input').bind('keypress',null,b).bind('change',null,a);
});
function a(){
[Code].....
this script bind both keypress and change of the text box to functions b and a. at keypress event handler if user type a char on input box the value of input box change to x and the user char discarded. In this case we expected to run the onchange (change) event because the textbox value is changed BUT this doesn't happen.
DOM2 does not provide a key event module. (http://www.w3.org/TR/2000/REC-DOM-Level-2-Events-20001113/events.html#Events-eventgroupings-keyevents) That's fine. I'm down with that.
According to the DOM3 Events spec (http://www.w3.org/TR/2003/WD-DOM-Level-3-Events-20030331/events.html#Events-KeyboardEvents-Interfaces) (in last call), there's no keyPress event, only keyDown and keyUp. Instead (I guess) they've defined a new interface for text events (http://www.w3.org/TR/2003/WD-DOM-Level-3-Events-20030331/events.html#Events-TextEvent), which provides one event type: textInput.
Should I not code event handlers for keyPress events if I wish to write DOM-compliant scripts? IE & Moz both register a keyPress; I'm sure that it won't be outphased. I worry instead about a new and better browser appearing and balking on my script because it's coded exactly to spec.
I have:
<div onkeypress="go(event)">...</div>
and:
function go(event) {
alert(event.keyCode);
}
but I always get 0 for the keycode.
Is there any cross-browser method of determining whether a click event was triggered by a mouse left click or the keyboard's 'enter' key? I was expecting event.button, or event.which to be able to do this, but this doesn't seem to be the case. Checking event.clientX == 0 && event.clientY == 0 works in FF, but not in IE.

I'm getting an error object required on the window.onkeypress line.
I have a data entry app and the users are keying with their right hand on the number pad and flipping pages with their left. If they want to use the normal tab key they have to take their hand off of the papers to do so. I figured it would be pretty simple to override the keypress even for the + key and divert it to act like tab was pressed instead.
I am trying to run some code if a series of keypresses the user types is equal to the correct series of keypresses.I know how to do this if I am just trying to get one keypress. But what about one after another?
View 2 Replies View RelatedI've got a script which is called by a keypress event, something like this:
<html>
<head>
<script type="text/javascript">
function respondToKey(e) {
keyPressed = String.fromCharCode(e.which);
if(keyPressed == 'g'){
alert('you pressed the g key');
window.open('http://google.com');
}
}
</script>
<title>Untitled</title>
</head>
<body onkeypress="respondToKey(event)">
hit the g key to open a google window
</body>
</html>
when you hit the right key, the alert appears, but the window.open() never happens. There's not even a message in the Error Console, just nothing.
Is this a security feature? Any way I can get around it? And, if it's a security feature, is the fact that it fails silently with no error message also a security feature? Because it's rather annoying.
I would like to create dynamic variable name and assign values to them.
Something like this:
I want to create these names dynamically.
I tried: var item{i} where i is the dynamic variable.
Nothing seems to be working.
I also tried:
It doesnt recognize : var eval('item'+i)
I am wondering why the following works, on IE6, but with an error : "Not
implemented".
function TEST(){}
TEST.prototype.Initialize = function()
{
var mImage = new Image();
var mDate = new Date();
var start = mDate.getTime();
mImage.onload = this.Alerting(start);//WORKS with ERROR "Not implemented"
//mImage.onload = function(){this.Alerting(start);}//ERROR "Object doesn't
support this property or method"
mImage.src = "winxp.gif";
}
TEST.prototype.Alerting = function(i_string){alert(i_string);}
var mTest = new TEST();
mTest.Initialize();
Can anybody guess why?
I have written a script that gets trigered by IE's toolbar button. In
this script I would like to asign an event handler to an element of the
document currently open in IE. The way one access the document object
from a toolbar button script is:
var doc = external.menuArguments.document;
Now assuming the document has an element called TextArea1, the logical
thing to do would be:
parentwin.document.all('TextArea1').onkeypress = new
Function('window.alert('asdf');');
Which goes compiles and runs, except the event handler does not get
triggered.
Another trick i tried is as follows:
var s = parentwin.document.createElement('script');
s.text = 'window.alert('asdf')'
s.htmlFor = 'TextArea1'
s.event = 'onclick'
parentwin.document.scripts[0] = s;
Same result.
I'm having troubles assigning an onclick event to a cell. Im trying
something like:
cursorPoint.cells[3].style.cursor = "hand";
cursorPoint.cells[3].width = "20";
cursorPoint.cells[3].onclick = "alert('this is a test');"
cursorPoint.cells[3].alt = "Select the columns";
cursorPoint.cells[3].innerHTML = " "
Everything is just working fine except the onclick. I also tried:
cursorPoint.cells[3].click = "alert('this is a test');" (without the
"on") but also didnt work.
I was wondering if anyone knew if/how to assign an event to
a global variable?
I tried to do it and IE 7 came back with an error saying "Member not
found"
My code looked similar to the following:
var globalEvevnt;
function showPopup(event){
globalEvent = event;
alert(globalEvent.type);
setTimeout(function(){unhideDiv()}, 2000 );
}
function unhideDiv(){
alert(globalEvent.type); //Member not found error found on this
line
}
I was wondering if I had declared the globalEvent = new Object();
would that make any difference? I thought everything in JS was an
object so the event could be stored to one as well?
I'm trying to assign and event to a tag during the onload function,but I don't seem to be using the correct syntax.

I have this code where we initialize the themeswitcher
[Code]....
where themeSwitcherSelect is my function, but it doesn't work. What am I doing wrong?
What I am coding now is a piece of a much larger project that I am, for the moment, developing on my own. This code, relatively useless on its own, is essentially practice or proof -of-concept. Much of it will probably be used in the larger project. If at times, it seems that I am using a cannon to kill a fly, this is why.
Additionally, I do not claim credit for all the code here. Some of it is copied from other sources. I have studied it, understood it , then modified it appropriately, making it my own.
However, the code is broken. I have tested it on Internet Explorer 9.0.??? and Firefox 4.0.1. It breaks in both browsers. I have previously tested it in Chrome, but not recently. On IE I have used the built in debugger, and I have been using Firebug in Firefox. I have also used the debugger at [URL] quite frequently. JSLINT returns some 'Bad Type' errors regarding 12 lines in the html body, each having the structure: <td><input /></td>. I can find no explanation for the 'Bad Type' errors. Otherwise, according to JSLINT, the code is fine.
The predecessor to this code worked fine. I had been using inline event handlers (onblur and oninput) that called the doMath function when one enters data into the table. The values are then averaged and summed. All this is extremely basic. The problem began when I removed the inline event handlers and began to use window.onload (I believe I am using document.onload now, but the problem has not changed.)
I have adopted Douglas Crockford's 'walkTheDom' recursive function to find all tags with a particular class name. I would like to assign every element in the array returned by this function an event handler.
This is the problem: This script simply cannot find the body node of the DOM ( and, seemingly, none of its child nodes either). Initially I tried 'document.body', which failed. I then began with 'this' (essentially 'document') and tried walking the DOM to get to it ('body') eventually. This, too, failed. I tried array index notation to refer to it(I forget the specific syntax), and most recently, I've given it ('body') an id and referred to it directly using 'document.getElementById()'. These most recent attempts also failed.
After hours of figuratively bashing my head against the wall looking at code and probably even more time doing research online, I am extremely frustrated. As often seems to be the case, my problem is probably simple
I have included most of the code, even though it is a little long. This way you may easily copy the code and reproduce the problem yourself. I do not often post to forums, and, more relevant, I have no idea where the error may be located.
Potential problem areas are in RED.

I've got 3 textboxes and 3 buttons on my form. When I press enter in the first textbox, I'd like to have a click performed on the first button. Same thing for the other 2.
I have a function that is called OnKeyPress event of my textboxes. 2 issues:
- How can I find out which textbox called the function ?
- How can I perform a click on a button (the appropriate one) from the code?
Here is a little sample code:
<html>
<head>
<script type="text/javascript">
function BodyClick() {
// How to access the event object here?
alert(window.event.shiftKey);
}
function WindowLoad() {
document.body.onclick = BodyClick;
}
window.onload = WindowLoad;
</script>
</head>
<body></body>
</html>
It does not work in FireFox. How to make it work?
My only requirement is that I need to assign the BodyClick() handler
dynamically in script (not statically in HTML). So I cannot use this solution:
<body onclick="BodyClick(event)">
I'm trying to add 2 functions to an event handler dynamically using javascript. The element that I'm adding the event to is also being created dynamically.
Here's my code:
newspan = document.createElement("span");
newspan.onClick = expandCollapse('category' + numCategory + ); ChangeStyle(this);
newspan.appendChild(newdiv);
I need onClick to run both the expandCollapse() and ChangeStyle(). ChangeStyle() needs to pass "this" to the function.
Nothing I've tried seems to work.
I have a page where I want to display buttons only when a particular list item is selected. The user can then click on one of five buttons. I am able to put the buttons in a <div> section using this
$("li.point").click(function(){
choice = $(this).attr('id');
Competition = $(this).attr('title');[code]..........
So i'm just getting into writing jquery. it's my first scripting language and first time in the field of programing. I have a general idea of what i want to do, but not so much how to get it done. Objective: I would like to change the class of a div "ActiveSelection" to the same name as the id of a clicked link in the "catalog" ul. Here is an example of the HTML
<ul id="catalog">
<li>link</li>
<li>link</li>
</ul>
<div id="stage">

The code below displays a dynamic table with all its contents in the form of links.I wanna know as to how i can detect whether any of the links in the table has been clicked.As the table is dynamic i am not aware of the syntax of how to use the onClick evnt handler for these links. Code:
View 9 Replies View RelatedI'm trying to create a dynamic table with onclick event like this but onclick event seems to do nothing:
var srcTable = this.iContext.getElementById("tbody");
var tmpRow = null;
var tmpCell = null;[code]...
I found a few examples like this: tmpRow.onclick = function() { alert(this.rowIndex);};
but I need use selected data, maybe call a defined function. I already tried lines bellow but nothing works, because doSomething is not function of tmpRow object.
tmpRow.onclick = function() { doSomething(this);}; or tmpRow.onclick = doSomething(this); or
tmpRow.onclick = "doSomething(this)";
For some reason my change() function is only called when the page loads. I'd
much rather it gets called when the select changes.
Here's the code:
window.onload = init;
function init() {
var new_select = new Selector('tdata','myselect','myid');
var new_select_list = new DataSource("some_list");
new_select_list.addItem(1,"One");
new_select_list.addItem(2,"Two");
new_select_list.addItem(3,"Three");
new_select_list.addItem(4,"Four");
new_select_list.addItem(5,"Five");
new_select.setDataSource(new_select_list);
new_select.formInput("form","input");
}
Selector = function(container_id,name,id) {
var container = document.getElementById(container_id);
this.node = document.createElement("select");
//this.node = new Select();
container.appendChild(this.node);
this.node.name = name;
this.node.id = id;
}
Selector.prototype.setDataSource = function(ds) {
this.dataSource = ds;
for(var i = 0; i < ds.items.length; i++) {
if(ds.items[i] != undefined) {
var option = new Option(ds.items[i],i,false,false);
this.node.options[this.node.options.length] = option;
}
}
}
Selector.prototype.formInput = function(form,element) {
var myform = document.getElementById(form);
this.input = document.createElement("input");
this.input.name = element;
//this.input.type = "hidden";
myform.insertBefore(this.input,myform.firstChild);
this.node.onchange = change(this);
}
function change(selector) {
alert("hello");
selector.input.value = selector.node.value;
}
DataSource = function(name) {
this.name = name;
this.items = new Array();
}
DataSource.prototype.addItem = function(id,item) {
this.items[id] = item;
}
and the html:
<html>
<head>
<script defer src="/javascript/selectors.js"
type="text/javascript"></script>
</head>
<body>
<form id=form>
<table border=1>
<tr>
<td>
Select:
</td>
<td id=tdata>
</td>
</tr>
</table>
</form>
</body>
</html>
In the below code snippet I'm trying to add an dynamic event in <div id="button3"> when you click at button1, which is added static in the html body. button3 has exactly the same behaviour as button1, but the eventhandler will not be activated.
