Can I Avoid Eval() Here?
Nov 23, 2006
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.

given that I have a js file included which is written programatically and I
can't change it. I would like to know how to do the following using
something other than the deprecated eval().
whats in the js file
var numArrays=something;
var data0 = new Array();
data0.name="name";
data0.data="some data";
var data1 = new Array();
data1.name="another name";
data1.data="some more data";
etc ....
function getData(arrayName) {
for ( var i=0;i<numArrays:i++) {
var el=eval('data'+i);
if (arrayName = = el.name) doSomething(el.data);
}}

var fns = ['orde', 'no', 'kml', 'snf', 'td', 'ty', 'tn', ...up to 21
elms...];
var snv = new Array();
var vals = new Array();
for (i = 0; i < N; i++) {
for (j = 0; j < fns.length; j++)
vals[j] = some value;
snv[i] = new makeData(vals);
}
function makeData(vals) {
for (k = 0; k < vals.length; k++)
//the following line doesn't work
eval("this."+fns[k]+"="+vals[k]);
//neither this one
this.eval(fns[k]) = vals[k]);
}
how can i make it without writing it the long way:
this.orde = vals[0];
this.no = vals[1];
this.kml = vals[2];
and so on?

I've made a funny program using eval()...it will let the person(on the page) to write javascript and have it compile(if thats the right word for it)! its quite cool, i dont know how handy it might be, but here it is none the less...
code:
<html>
<head>
<title>test</title>
<script language="JavaScript">
function submitCode(){
var the_code = window.document.form_1.textarea_1.value;
var run_the_code=eval(the_code);
}
</script>
</head>
<body>
<center>
<h1>write some code!</h1>
<form name="form_1">
<textarea name="textarea_1" rows=10 cols=40>
</textarea>
</form>
<form onSubmit="return false;">
<input type="submit" value="submit your code" onClick="submitCode();">
</form>
</center>
</body>
</html>
very simple stuff, but for those of you who are unfamilir with eval, its pretty cool, huh?

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>

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.

I'm having some weird problem with evaluating the continue statement.
Within a for loop I'm trying to evaluate a string (generated somewhere
earlier) which basically has the continue statement in it. IE6 seems to
have major problems with that as it generates an error "Can't have
'continue' outside of loop". Does anyone know why and/or have a
workaround? I haven't tried any other browser since this one is the
only one available (company policy).
I have included some code to reproduce this behaviour. The first and
second if statements of the testeval function behave as expected. The
third one however produces the mentionned error. Code:

alert(node.myid);

{
this.myid="aa";

In CallDisplay() I am getting the error as "Microsoft JScript

I'm running some javascript over a server side generated web page
and have multiple generated empty select statements, that I want to
populate when the page is loaded. As HTML doesn't do arrays each
select is individually named withe MySelecti where i is an incremental
from 1.
I know all my variables are correct (i, OptionsCount) and my arrays
of MyValues and MyDescription's exist for multiple enteries and if I
bring out an example of what I thought each line would eval too( say
document.MyForm.MySelect1.options[1]=new
Option('Value1','Description1') the line works fine, for the life of me
(i'm sure I'm missing something obvious) the eval line won't eval..
for(i = 1; i<=row; i++) {
for (j = 1; j <=OptionsCount; j++) {
eval="document.MyForm.MySelect"+i+".options["+j+"]=new
Option('"+MyValues[j]+"', '"+MyDescription[j]+"')";
eval(eval);
}
}

i came up with the following, to help me test the syntax of functions while i'm writing them. i've only been using it for a day or two, but so far, it's been really handy.

<META HTTP-EQUIV="Content-Script-Type" CONTENT="text/javascript">

<BODY>
<FORM>
<TABLE WIDTH="100%" HEIGHT="100%">

In Visual Basic this is easy to do, but I'd like to do it in JavaScript (without writng my own).
I'd like to put a text box on a form so the user can type something like:
3+5*(sin(90))^2
and have the answer to the equation displayed.
I guess it would be possible to translate it into a javascrip command
x=Math.pow(3+5*(Math.sin(90)),2) and then execute the translated line using Eval(x);, but maybe there's an easier way. Any thoughts?

I have a script that will loop through all the INPUT elements of a form; if the input is a submit it will disable the submit (or enable the submit, depending upon what is passed to the function.) I hate using eval() - I avoid it whenever I can! Is there a better way to dynamically process the ".disabled = 'true'/'false';" portion?

this is the code I'm working on:
Code:
var tabs = new Control.Tabs('menu');
var pattern = 'tab=';
var nStr = location.href;
if(nStr.match(new RegExp (pattern,'gi'))){
var id = nStr.split(pattern);
[Code]...
It searches for the query string 'tabs=' and then splits the result to get the id of the tab. Then it uses this to set the active tab. If the url doesn't include the query string it set the tab to the first one.
The code works but it uses Eval to convert the id string (id[1]) to a variable and I was wondering if there was an alternative.

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?

How to force JS not to convert the string ? I want JS to send exactly what

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.
