Avoid Enter Key In IE And Netscape
Jul 20, 2005
I wrote this function to avoid the enter key in some of my textboxes.
In IE the function works as expected, in Netscape 6 or 7 it does not
work. How can I make my function works in both IE and Netscape.
<input type="text" maxlength="13" id="txtType" onKeyPress="NoEnter();"
/>
<Script language='Javascript'>
function NoEnter()
{
if (window.event.keyCode == 13)
{
window.event.cancelBubble = true;
window.event.returnValue = false;
}
}
</Script>

I have a text box and everytime I press enter on it I get the form submited. How can I avoid that behaviour? I tried:
for the text onKeyDown="donotsubmit()"
Code:
function donotsubmit {
var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;
//alert(keyCode);
if (keyCode == 13) {
document.form1.submit()=false;
}// if
}
But dosen't seem to work.

I am trying to assign an "onclick" event to a dynamically-created DOM
element (an image).
I have read countless times that "eval()" is to be avoided at all costs.
However, I cannot seem to get my new onclick to work without it.
Here's what I have so far:
myeval = 'detachFile(this);'
detachImage = getElementById('detach-jfhahhf');
detachImage.onclick = function() { eval(myeval) }
This works perfectly fine for me, but this is a web-app that will be
exposed to public users, and I obviously don't want them being able to
eval anything if i can help it.
Can that be done without the eval()?

I'm using an ActiveX control in my html page.. Each time i load the page ie pops a message box to allow the activex to run or not . Is there any way to handle that message box using javascript. Or is there any other way to avoid that message box because each time the page loads i have to give yes and then proceed. By default i've to give yes is there any way to handle that using javascript.

Im working on a project for my website where I would like to be able to change the value of a number by using js, and using getElemenById. For example:
"The taxi fare is $25"
"A hamburger is $4"
In the above sentence I would like to be able to change the value of 25 & 4 by giving them an id and then using js to increase (or decrease) their value, to allow for future inflation, without having to go back and manually change every number on lots of pages (if for example in 1 years time a hamburger is worth $6 then the info above is outdated and should be changed). If i could use a variable such as "RateUSD = 1" I could increase "1" to say "1.05" and it would increase the value of all id='USD' by 5% onload rather than having to manually change it by typing.
I so far have come up with the code below, but I think the reason it does not work is because I have created a circular equation - id='USD" is the start of the equation, but it is also in the equation itself, and it is the resulting answer, so effectively I have created "A = A*B", or in this case "25 = 25*1.1"
I chose "id" as I would like to be able to have different currencies (with different id, such as 'EURO','GBP', etc) on the same pages and on multiple pages. I'll crack it eventually, I would just like to know if I'm heading in the right direction, or is there a better method that I could use? I found plenty of example for changing text with "innerHTML", but so far I haven't seen any for updating numbers onload by calculation, except for forms, etc, which are different.
The code:
<html>
<head>
<script type="text/javascript">
function changeCurrency(){
[Code].....
I will later put the js in an external file with a link to it "...src="support-files/currencyChange.js" (or something like that), but for now I have put it on the same page.

Is it possible to have only vertical scrolling enabled on a DIV?
style="BORDER:1px ; OVERFLOW: auto; WIDTH:799px; HEIGHT:249px;position:
absolute; top:0; left:0; "
will have both horizontal and vertica scrollbars once the dim of the content
exceeds the DIV's size.
Can it be made so only vertical scrollbars will appear?

I'm writing a very simple code. Basically, there will be an array of strings from which one is randomly chosen and written to an element on the page. Here is a simplified version of how I'm executing it:
<html>
<head>
<script type="text/javascript">
function dyk() {
document.getElementById('test').innerHTML = "foobar"; }
</script>
</head>
<body onLoad="dyk();">
<div id="test">Hello<br />
</div>
</body>
</html>
My only concern is the "Active Content" warning that comes up in IE. The clientele (mostly older people) are probably going to be IE users and many of them might be so untrusting of computers that they'll take the warning as a legitimate concern. Is there another way to write this simple code to avoid the warning?

Say that you have a table with id Testresults. Now you also would like to show diffrent parts of that table inside diffrent divs that also contain a table.
for example
Code:
<div id="OK testcases">
<table id="oktestdiv">
<tr id="row1" class="ok"><td>ok</td></tr>
</table>
[Code]....
I naturally don't want to write the code for the table at multiple places of the page. Notice also that my site only contains of one site, containing many divs.

How to avoid the execution of a function at the time of defining.
Here i am giving the details.
I am creating the following div container through DOM.
<div id="content">
<a href="#" onclick="displayDiv('content')" Click</a>
</div>
The Code is:
var category_list = document.getElementById('category_list');
var dom_div = document.createElement('div');
dom_div.id = 'content'
var dom_link = document.createElement('a');
dom_link.href ='#'
dom_link.onclick = displayDiv();
val = document.createTextNode('Click');
dom_link.appendChild(val);
dom_div.appendChild(dom_link);
category_list.appendChild(dom_div);
The displayDiv Funcion
function displayDiv()
{
dv = document.getElementById('content'); //Here is the error.
}
The Problem is when the following script:
dom_link.onclick = displayDiv('content');
is executed it is calling the function displayDiv(name)
Here we have the code
document.getElementById('content');
which throws the error.
The reason is the div container is not yet created.
What I need is the function should be called only on the click event. It should not be called while I define it to the Click Event. (ie it should not be called at the time of defining)
How to achieve this.

I have developed a plugin for mutual selection on a list of elements.It works fine if I make those element into mutual list only once.
like $("appropriateSelector").toMutualSelect();
that plugin will add click event handler to each element and they remember the whole list by enclosure.
If I add new elements to that list. and do$("appropriateSelector").toMutualSelect(); again. New elements will behave as expected but old ones will have problems. Each old element will have the same handler bind multiple times to them. That will result like toggle two times andmessingup the outcome. How do I prevent this? I am trying to clean up their bound handlers but seems no luck.

how to avoid temporary (local) variables to reassign this.Example as follow:
function Test(id){
this.id=id;
this.init=function(){
// some initialization go here
[code]....
This is terrible because it breaks the structure, and so many local temporary variables will be instantiated (possibly they will eat up the memmory).However, this type of reference is just so popular in jQuery, and they got a beautiful solution. Example:
$('li').each(function(){
// Do with $(this). This is beautiful, but I don't understand how could they make this scheme.
})

Is there any method to avoid loading js files of iframe. For example, if I loaded jquery from the main (parent) page, and don't want to load an 'extra' jquery of iframe. How could it possible? Generally, it is about calling javascript functions in iframes, which is already loaded from parents.
