Can't Inspect Or Watch Variable In Microsoft Script Debugger.
Oct 3, 2006
I have a javascript program that works fine under Firefox and on IE
when running XP, but is having a problem with IE running under Windows
2000 Pro.
On my personal XP development machine I have the Microsoft Script
Editor and I can set a breakpoint, step through code, inspect
variables, etc... with no problem.
On a machine where I am trying to debug this problem I am running
Windows 2000 Pro with IE 6. I installed the Microsoft Script Debugger.
When the program hits the exception the script debugger will come up
and show me the line where the error occurred.
I need to be able to inspect the variables to determine the problem.
However, from what I can tell, there isn't anywhere to inspect or watch
the variables in MSD?

Is there any way we can watch variable values inside javascript functions while running through the debugger. I am using javascript along with ASP.net on Visual studio 2010.

I'm trying to style a fugly advertisement that pops in on my page. Right now I have a standard setTimeout going, but it could take 2 seconds, or 5 seconds after document.ready triggers :/
Is there a way to somehow put an event on a div to watch for an ID to appear perhaps?

I am building a simple timer. It works ok, but doesn't do everything it is suppose to do. When pos1 reaches 1, it is suppose to reset the timer and display an alert message saying that it has reached the maximum time. It does that just fine but after it resets, it starts over automatically and I don't know why[code]

I'm trying to add watch() to IE, and have more or less working code:[code]That works until I try to use setInterval with the code in red color. I never really tried OOP or prototyping in JS, so my whole approach to the problem might be wrong, but anyway, I think that if I execute that code in red every 100ms [for example], I'll be able to catch changes to properties on which the method is registered. Well, either my idea is wrong, or the execution.Some parts are commented out and method name is changed so that I could work in peace in FF.

What debugger would let me see the HTML in a div after I've added HTML
to the div using its innerHTML? That is:
var someInputHtml = prompt("input html");
var referenceToSomeDiv = document.getElementById("someDiv");
referenceToSomeDiv.innerHTML = someInputHtml;
When debugging, how do I now see what HTML is in the div "someDiv"?
Maybe there is a FireFox extension for this? Firebug?

I would like to download debugger for javascript.
Since I works only with IE I thought of trying using the Microsoft Script
Debugger.
I found the following URL
http://msdn.microsoft.com/library/d...tml/sdbug_1.asp
My problem is that I can't find the URL to download the debugger.
Any other JS debugger that works well for IE ?

I finally got tired of doing:
alert('myVar: ' + myVar);
and
str='' for(i in someObject) str+=i+': '+someObject[i]+'' alert(str);
and put together a little debugger to take care of that.
I bet I'm not the first one, but when it comes to JS my motto is "If you want to do it right.
Anyhow here is the demo, you are welcome to view and use the source, just leave the credits...

This is a script that frequently keeps me from using bad words.
It loops through an object and returns its properties in text (for alert) or html format.
Usage:
_viewObj(obj[,instanceName[,type[,levels]]]);
Ex:
var obj = {id:3,arr:[2,3,"str",{prop1:2,prop2:""}],nr:3}
alert(_viewObj(obj));
document.write(_viewObj(obj,"obj","html"));
Parameters:
pValue: The object
pName: Instance name of the object. Default: "input"
pType: Which type to be return (text or html). Default: "text"
pLevels: The max amount of levels. Useful if an object references a parent. Default: infinite
Returns:
A string with the properties
function _viewObj(pValue,pName,pType,pLevels,pObj) {
function objExists(pCurr) {
for (var i=0; i<pObj.length; i++) {
if (pObj[i]==pCurr) {
return true;
}
}
return false;
}
pType = new String(pType).toLowerCase();
if (new String(pName) == "undefined")
pName = "input";
if (new String(pType).search(/html|text/i) == -1)
pType = "text";
if (pLevels == "undefined")
pLevels = -1; /* Infinite */
if (typeof pObj == "undefined")
pObj = [];
var str="";
if (typeof pValue != "function") { // No functions / methods - just values
var br=(pType == "text"? "
" : (pType == "html" ? "<br>" : ""));
if ((typeof pValue == "object" && !!pValue) && (pValue.length) && (!pValue.substring)) { // An array
try {
for (var i=0;i<pValue.length;i++) {
if (pLevels==0) {
str+=br+pName+"["+i+"]: "+pValue;
}else{
str+=""+_viewObj(pValue[ i ],pName+"["+i+"]",pType,pLevels-1,pObj);
}
}
} catch (e) {
str+=br+pName+": "+pValue+" (Not an array)";
}
} else if (typeof pValue == "object" && !!pValue && (!pValue.substring)){ // An object
try {
for (var prop in pValue) {
if (pLevels==0) {
str+=br+pName+"."+prop+": "+pValue;
}else{
if (typeof pValue[prop] == "object" && objExists(pValue[prop])) {
str+=br+pName+"."+prop+": [Parent Object]";
}else{
pObj.push(pValue);
str+=""+_viewObj(pValue[prop],pName+"."+prop,pType,pLevels-1,pObj);
}
}
}
} catch (e) {
str+=br+pName+": "+pValue+" (Not an object)";
}
} else{// if (typeof pValue != "object") { // Simple value
str+=br+pName+": "+pValue;
}
}
return str;
}
edit:
Avoiding never-ending loops by checking for parent objects.
Ex:
var parentObj={id: 2};
var test={id: 1,par: parentObj};
parentObj.tst=test;

According to the Sitepoint FAQs, most serious programmers debug their scripts by hand, but when my javascripts don't work , I like to be told why, the more explicitly the better.
I used to have NN4 and its debugging was fantastic (certainly more helpful than IE and Opera, although theirs aren't too bad). I was just wondering what other people think is the best browser/resource for debugging javascript. If it's Netscape, does this mean I have to download the whole browser, and does the debugging vary with version number? Which would be the best to get? (Note: I'm only interested in its debugging capabilities, not its quality as a web browser).

Mozilla-based browsers have watch and unwatch methods to detect change
in value of form elements (or any Javascript variables really). IE
doesn't support this.
Is there a a reliable cross-browser way alternative to this? Something
that will let me detect a change in value for a form element and
trigger my own callback function upon change?
Hopefully, something that is generic enough to be called as
"MyWatch(element)"!

Here is a simple script to simulate the page being coded as it loads.
Here is the script....
----------------------------------------
<script language="JavaScript">
var x = 2;
var y = 0;
var h = 0;
function LineBy()
{
bodyarray = document.body.innerHTML.split('
');
document.getElementById('mover').style.height = document.body.clientHeight - h;
var currentline = String(bodyarray[x]);
if (currentline.charAt(y) == "<") displayed = "<";
else if (currentline.charAt(y) == '"') displayed = """;
else (displayed = currentline.charAt(y))
document.getElementById('mover').innerHTML+=displayed;
document.getElementById('mover').style.top = parseInt(document.getElementById('mover').style.top) + 2;
if (y <= currentline.length) {y++;}
else {y=0;x++;document.getElementById('mover').innerHTML="";}
if (parseInt(document.getElementById('mover').style.top) >= (document.body.clientHeight-20)) {document.getElementById('mover').style.visibility="hidden";return;}
h = h + 2;
setTimeout('LineBy()',1);
}
</script>
----------------------------------
Place this inside the body tag.
----------------------------------
onload="LineBy()"
----------------------------------
Then include this DIV inside the body tag.
----------------------------------
<div id="mover" style="font-size:7pt; position:absolute;top:0; background-color:FFFFFF; visibile:hidden; width:100%;z-index:5;height:100%"></div>

I'm pretty new to JS, used to be back-end guy with strong front-end skills (HTML, CSS), learning JS now and I have a huge problem.
I'm using Windows 7, coding mostly in NuSphere PhpED, but I see it doesn't work so well for JavaScript.
What's the best tool for JavaScript coding in Windows, maybe with built-in debugger (I hope there's something else than Firebug, Dragonfly etc.) with syntax coloring, and perfectly with a feature like this one
Maybe you do know the best syntax-help Windows editor for PHP too? (PhpED is not perfect IMO). Eclipse?
BTW - if there are any OSX based front/back-end webdevs - put screens of your editors features (JavaScript & PHP preferably). I'm thinking about switching to MAC, but haven't got cash for that at this moment (and I'm kind of Apple hater, however I believe in front-end field they have no contest).

I have a Joomla website which are using VirtueMart. I want to watch the submit of a product (which is using AJAX) and when the request is succesful and complete then send a new XHR request to upload another part of the website.How do you think I should do with Mootools?I first success to do it but only by adding an event on the form submit. So when I click on the Add to Cart button, it is working but I would like to wait until the first request is complete.

I'm trying to translate an asp application, i have some difficulties with a
particular line :
---
Set myxml = Server.CreateObject("Msxml2.ServerXMLHTTP.4.0")
---
Classical ajax exemples rather use :
[...]
req = new ActiveXObject("Microsoft.XMLHTTP");
.... But i'm not sure the ActiveXObject is identical to the original :
Set myxml = Server.CreateObject("Msxml2.ServerXMLHTTP.4.0")
I'm not an asp expert, can you give me some tips on that question ?

I am trying to use AJAX and JSON to do this. I have copied an example of
using HttpRequest Object as the backbone of this from
http://www.w3schools.com/dom/dom_http.asp. Further, I am enclosing both of
my files here, in full as opposed to mere snippets. This code does what I
wish it to do except:
1. It does not update when getdata.php is rewritten. On non MSIE broswers,
it shows when first invoked, but not subsequently.
2. It fails altogether under MSIE (6.026 SP1 || SP2) -- I never get
xmlhttp.readyState==4 under MSIE.
Code:
