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?
Is there a free JavaScript debugger available?
View 5 Replies View RelatedI 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'm looking for a good javascript debugger.
View 3 Replies View RelatedI 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).
Whenever I stop the IE script debugger it closes the browser window as well.
View 2 Replies View RelatedI recently learned about a new Javascript Debugger called FireBug. From what I've heard, it's pretty good. Here's the link: Code:
View 4 Replies View RelatedI have both firebug and venkman debuggers installed. Both seem to function yet neither works. I use firefox3.5.3., windows xp.
View 2 Replies View RelatedI'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).
Javascript issue: IE suggest bug but no code is reported in the debugger. Any ideas why IE doesnt find the broken code / or line
View 1 Replies View RelatedI 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 a way to add an if and else with in innerHTML like this.

I'm currently using AJAX to perform some dynamic updates and return some text to the web page. At the moment I'm using innerHTML as follows:
document.getElementById('WrkItemDiv').innerHTML=wrkItemReq.responseText;
but I'd like to be standards compliant. How would I do this using pure DOM stuff?
btw WrkItemDiv is an exisiting <div> I simply want to overwrite the text within it with the newly returned text.
Also, is it possible to change the onMouseOVer code with some text returned in the same way as above using pure DOM?
I am getting data from two tables in a database using a dropdown box with a onchange and some ajax to update two diferent Div tags, basically the id is passed to a php page,, I grab the data from the two tables, I then echo the data in two html tables. I echo a ** for a delimiter between the two tables,
Then I use a javascript split function to split the responseText into two peices so I can update each DIV with the coresponding data.
Everything works in Firefox, but in IE7 only one div gets updated with its data, the other div will not change, and I get a unknown runtime error. However if I go into my php page and change the data I am echoing after the delimiter to a simple echo 'test' it will work. Code:
I've got this code that creates a new new row and cell. I then put some
text into the cell with innerHTML - works beautifully with Firefox but
fails with IE. I guess IE doesn't support this way of doing it, but is
there another way of doing it with DOM?
newr = document.createElement('tr');
stbl.appendChild(newr);
newc = document.createElement('td');
newr.appendChild(newc);
newr.cells[0].innerHTML = (nr+1)+". "+sa[ti][nr + 1]+"<br><hr>";
(works in firefox but fails in IE 6+ too...)
Here is my problem in a nutshell: a script to model dynamic table
extension. It works under Firefox. But IE just aborts, complaining about
an "unknown runtime error" in the line with "innerHTML". Why?
<html><head></head><body>
<script language="javascript">
function extend() {
var tb = document.getElementById('thetable').tBodies[0];
var newrow = document.createElement('tr');
tb.insertBefore(newrow,tb.rows[tb.rows.length-1]);
tb.rows[tb.rows.length-2].innerHTML =
'<td>A</td><td>dummy</td><td>row</td>'
}
</script>
<table id="thetable">
<tr><td>1-1</td><td>1-2</td><td>1-3</td></tr>
<tr><td>2-1</td><td>2-2</td><td>2-3</td></tr>
<tr><td>3-1</td><td>3-2</td><td>3-3</td></tr>
<tr><td colspan="3"><a href="javascript:extend();">extend</a></td></tr>
</table>
</body>
</html>
IE seems to munge the innerHTML of a document, does anyone know why
it's changing the innerHTML?
<body>
<div style="background-color:LightGrey;" onclick="window.alert( 'one:'
+ getElementById('one').innerHTML );" id="one">
<table id="tableone">
<tr id="trone">
<td>click me</td>
</tr>
</table>
</div>
<div id="two" style="background-color:LightBlue;"
onclick="window.alert( 'two:' + getElementById('two').innerHTML );">
<table id="tabletwo">
<tr id="trtwo">
<td>click me too</td>
</tr>
</table>
<input type="checkbox" checked="checked" value="MYVAL" />
</div>
</body>
Why doesn't a SELECT element's innerHTML reflected which option was
selected? Works in IE. I need this functionality so that I can retain
what choices a user made in a tabbed interface.

I am using a frameset with two frames that looks like this:
|------------------------------|
| |--------------------------| |
| | FRAME 1 | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| |--------------------------| |
| |
| |--------------------------| |
| | FRAME 2 | |
| | | |
| | <html><body> | |
| | <table><tbody> | |
| | <tr> | |
| | <td>Data 1</td> | |
| | <td>Data 2</td> | |
| | </tr> | |
| | </tbody></table> | |
| | </body></html> | |
| |--------------------------| |
|------------------------------|
FRAME 2 has no height, so it looks as if you only have 1 frame. I am
using FRAME 2 to retrieve data from my server.
I open up FRAME 1 with my webpage and leave FRAME 2 empty. When the
user request data I target FRAME 2 and the data is loaded into FRAME 2.
What I have been trying to do is this. Take the innerHTML of the FRAME
2's table and load it into a table in FRAME 1.
I want to load an external file into my page via XMLhttpRequest and
innerHTML. The external file contains javascript code which is not executed during
or after insertion. All the HTML markup is displayed just fine....
basicly even this code doesnt work:
<div id='tmp'>original Content</div>
<script>
document.getElementById("tmp").innerHTML="<b>new</b>
Content<script>alert('not shown! why?');</script>";
</script>
looking at the page, "new Content" is shown with "new" bold as
expected, but there wont be the javascript alert!
I use Ajax to retrieve part of a page I need to update. I update a DIV
element with the HTML contents I get from another page.
It works fine.
However the HTML have a SCRIPT tag that the browser should process, but
it doesn't.
Here's an example:
--- pageX.aspx ---
<table>
<tr>
<td>Table 01</td>
</tr>
</table>
<script>
alert("HI");
</script>
--- end pageX.aspx ---
--- page on browser ---
<div id="divContents"></div>
<script>
divContents.innerHTML = getHtmlFromPage("pageX.aspx");
</script>
--- end page on browser ---
When the prowser gets the "pageX.aspx" and updates the contents of the
'divContents' it displays the table, but it didn't process the script.
What am I doing wrong?
if i use AttachEvent like this,it can't work;
eg:
var img = document.createElement("img");
img.attachEvent("onclick",alert("test"));
var div = document.createElement("div");
div.appendChild(img); //can't work;
div.innerHTML="<-click this";
but i use attachEvent like this,it work; eg:
var img = document.createElement("img");
img.attachEvent("onclick",alert("test"));
var text = document.createElement("span");
text.innerHTML="<-click this";
var div = documet.createElement("div");
div.appendChild(img); //can work
div.appendChild(text);
Is there any way to use a variable.innerHTML = ""; instead of text.innerHTML
= "";? It doesn't seem to work for me.
How can I get the innerHTML of a <div> area only when the page loads, then use that variable in a function?
Here is my code:
function setContent(zz)
{
var lb = document.getElementById('leftbar').innerHTML;
var rb = document.getElementById('rightbar').innerHTML;
document.getElementById("myContent").innerHTML = "<span class="title_Page">"+Page[zz]+"</span>";
if (zz=="home") {
document.getElementById('leftbar').innerHTML = lb;
document.getElementById('rightbar').innerHTML = rb;
document.getElementById('leftbar').style.width = 食px'
document.getElementById('rightbar').style.width = 食px'
}
else {
document.getElementById('leftbar').innerHTML = "";
document.getElementById('rightbar').innerHTML = "";
document.getElementById('leftbar').style.width = Ɔpx'
document.getElementById('rightbar').style.width = Ɔpx'
}
}
I want lb and rb to be set only once (i.e. only when the page loads the first time). I tried putting those variables outside the function, but when I do they, they show up as undefined. So how could i code it so that when the page loads, it assigns the innerHTML to the two variables, but not any other time while that page is open?
