JQuery :: Preventing The Execution Of Code Called By GlobalEval() / Eval()?
Dec 5, 2011Until now I have used the javascript function eval(), wrapped it in a try / catch block and showen him the error message if the javascript code was flawed.But this comes with the problem that if there is no error the script will be executed.So what I´d like to is use the jquery function globalEval(), wrap it in a try / catch block and display the error message if the script does not run sucessfully as I have done before,BUT:if the script would execute without an error I´d like to use some kind of preventDefault so that the script would not be executed at all and instead I could show the user a message that the script passed validation.I know that the way I propose is not possible as the script has to be executed somehow so that possible errors are generated...does anyone have an idea how to do what i propose ?

'executing Code Retreived By XMLHTTPRequest
Oct 27, 2007I am having some difficulties getting some inline js code to run when
retrieved via AJAX by XMLHTTPRequest.
Basically I am running a php script every 15 secs or so that does a query of
a mysql database, checks to see if any new chat requests have been sent to
the user, and if so, it is simply returning them via a "echo" statement, and
the info is placed into a DIV in my sidebar.
Now when I add something in like:
<script type="text/javascript">
alert('you have a chat request');
</script>
it runs if i go ahed and run the script by itself, i get the chat requests
and the alert to popup. When the script is called via AJAX and loaded into
the div, I get the message from the mysql query about chat info, but no
javascript alert.
Am i just missing something stupid here? Like I said, it works when I run
the script by itself, just not when called via XMLHTTPRequest.

Jan 12, 2010I've run into a roadblock I just can't seem to get past. I'm developing a website for work (internal) and I have a lot of javascript calculations going on when someone enters data. What I want to do is to have a div apear when it begins calculating and goes away when it ends. I'm using:
// CSS code
div.loading-invisible{ display: none; }
div.loading-visible { display: block; ... various formatting here ... }
// Javascript
function calculate(evalForm) {
document.getElementById("loading").className = "loading-visible";
[Code]...
It works great in firefox. The div display appropriately, calculates, then disappears when it's finished. However, in IE it seems to want to calculate everything before anything is displayed. I placed alerts in the code to be able to pause it mid way and it worked. But without alerts it just hangs while everything is being calculated and the code for the loading screen just seems to cancel itself out. I attempted to put some waits in the code such as:

Dec 2, 2010I am doing a simple function to validate text fields(you can see the code below). Now, the alert box appears only once when I refresh the page, not when I click inside or outside the username box. #username is the id of a input text field. On a sidenote, how can I pass multiple parameters to the function(not a fixed number of params)? or should I just pass an array?

Jquery :: Executing Block Of Code Every X Seconds?
Feb 24, 2010I'm working on a simple slideshow made with jQuery. What I'm trying to do now, is to make it change image every X second. I know how to change image, but i'm kind of stuck trying to find out how to make it "do something" every Xth second.
Here's an example: (obviously not working..)
function slideSwitch() {
//change image...
}
setInterval(slideSwitch, 5000);
//make the function slideSwitch execute every 5th second.
Also, is there any "else if" function in jQuery? Like in for example PHP, you can use "if", "else if" and "else".. like this:
if(){
}else if(){
}else {
}
So is there any function like that? I googled it, and I found out I have to use some kind of plugin for it to work? How do I use it?

Eval() How Else
Jul 23, 2005given 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);
}}
How To Use Eval?
Jul 23, 2005var 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?

Using Eval()
Jan 28, 2004I'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?
Eval And Continue
Aug 23, 2005I'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:
Javascript Eval

Problem With Eval
Apr 17, 2006Here is my code.

{

Eval Problem
Aug 30, 2006I'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);
}
}
Can I Avoid Eval() Here?
Nov 23, 2006I 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()?
Nifty Use For Eval()
Sep 8, 2002i 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.

Eval Function
Apr 12, 2006In 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?
Better Way To Evaluate Than Eval()?
Nov 3, 2010I 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?

Looking For An Eval Alternative?
Aug 29, 2009this 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.
