JQuery :: How To Debug Syntax Error

View 1 Replies View RelatedDebug Script That Works OK In Firefox And Not In IE?
Jan 22, 2011I have a couple of problems with my site related to javascript
These areas of the site use jquery and they work fine in Firefox and Chrome but not in IE
First problem is related to tablesorter and pager (jquery plugins) that give a properly paginated list of members in Firefox but gives all the returned members in one big list using IE (and usually a complaint that 'this script is taking too long' as well)
The other problem is related to the member search age, it has these expandable areas where the user can select further search criteria - they use jquery 'slider' to reveal the collapsed areas, again this works fine in Firefox or Chrome but looks messy in IE
To compound the problem the only javascript debugger I have is a plugin for Firefox called Venkman which I find pretty useful to find problems with AJAX etc, but seeing as the jquery/javascript stuff works OK in Firefox it's difficult to fix what isn't wrong there!
So really, how do I go about even beginning to understand these problems so I can fix them?

View 1 Replies View RelatedDynamically Writing Html/javascript From A Javascript Function
Jul 23, 2005I'm working on some code and am running into brick walls. I'm trying
to write out Javascript with Javascript and I've read the clj Meta FAQ
and didn't see the answer, read many similar posts (with no luck
though), and searched through the IRT.ORG Faqs
(www.irt.org/script/script.htm).
The Javascript is designed to open an popup window and then inside that
window call another script which will resize that window. There may be
another way around this but the reason I tried this approach initially
was that I wanted to call the onload handler in the popup window to
resize the image only after the image had completely loaded. I've had
some code in the primary Javascript file (showimage.js) before that
works if the image has been cached but on the first load, it doesn't
resize properly which tells me it is probably because it is trying to
resize the window based on the image size but it isn't completely known
at that point. So I removed that code and tried placing the resizing
code in the second Javascript file (resizewindow.js). BTW I've tried
other code to open a popup image and automatically size it ie Q1443 at
irt.org but that doesn't do exactly what we need.
Even if there is another way to do this with one file, I still want to
figure out why this isn't working in case I run into it in the future.
I thought what I would need to do to use document.writeln to write
Javascript would be to escape any special characters and to break
apart the script tag ie
document.writeln('</SCRIPT>');
would become
document.writeln('</SCR' + 'IPT>');
I have a HTML page and 2 Javascript files. All files are in the same
directory and have permissions set correctly.
Here are the 3 files (keep in mind wordwrap has jacked up the
formatting):
index.html
----------
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Test</title>
<SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1"
SRC="showimage.js">
</SCRIPT>
</head>
<body>
Click the house<BR>
<A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG
SRC="house1thumb.jpg"></A>
</body>
</html>
showimage.js
------------
function newWindow1(pic,sitename)
{
picWindow=window.open('','','width=25,height=25,sc rollbars=1,resizable=1');
picWindow.document.writeln('<html> <head>');
picWindow.document.writeln('<SCR' + 'IPT type="text/javascript"
LANGUAGE="JavaScript1.1" SRC="resizewindow.js"></SCR' + 'IPT>');
picWindow.document.writeln('</head>');
picWindow.document.writeln('<body onload="resizewindow();">');
picWindow.document.writeln('<img src=' + pic + '>');
picWindow.document.writeln('</body> </html>');
picWindow.document.close();
}
resizewindow.js
---------------
function resizewindow()
{
// Do resizing here.
// Right now this isn't being executed
alert("resizing window");
}
Can anyone provide some pointers as to why this javascript is failing?
I'm using IE6 on Win2k and when I click on the image to open the popup
window, it does open the window but it is white with no content and the
system immediately goes from about 4% CPU usage to 100% and
consistently stays there until I kill that window with the task
manager.
DOM Javascript - Imbed Javascript In Dynamically Added Row
Jul 23, 2005Attached is a simple HTML file that adds and delete rows. In the add
row function I set an attribute "onClick" this triggers the
testMessage() function. When I try this in Firefox it works just fine
however on IE it just refuses to work.
What is interseting is the ROW that already exists has a similar
'onClick' event which works when the page is loaded, but subsequent
"row" additions to the table to not work in IE. Code:

Javascript Function Has No Properties In Javascript Console
May 25, 2005I'm getting errors in Firefox everytime I try to run this frame resize code, but it works fine in IE. I can't seem to figure out what the problem is with it.

Line: 8
The line that the javascript console is showing an error for is in italics.
code from page:

var hiddenCols="0px,*";
function ShowHideMenu(){
theFrame = document.getElementById("framed");
if(theFrame.cols == defaultCols) theFrame.cols=hiddenCols;
else theFrame.cols=defaultCols;
}

'Javascript Anthology' Or 'Professional Javascript For Web Developers'?
Mar 30, 2006I'm already past the basics of Javascript, and i need something that takes me to the other level and teaches me the new technologies and cool stuff (drag&drop, AJAX, OOP in javascript, maybe XUL...etc). So far i found these two books:
1. Sitepoint's "The JavaScript Anthology: 101 Essential Tips, Tricks & Hacks".
2. Worx's "Professional JavaScript for Web Developers (Wrox Professional Guides)"
Both seems to cover very insteresting topics, but i can only buy one of them. So which one do you suggest?
and by the way, i've read the sample chapter 5 of Sitepoint's book, and it seems like the author(s) just put the solutions/codes there and let you figure them out on your own. Is this how the rest of the chapters are?
Nixing Javascript Via Javascript: Pseudoproto?
Jul 23, 2005This is a question about defensive web browsing. Ocassionally I run into a page whose JavaScript does something that I find obnoxious. I would like to turn off JavaScript only for that page (instead of disabling it globally). It would be cool if there were some way to do this through a "bookmarkable" JavaScript snippet using the javascript: pseudoprotocol. Does anyone know any trick to do any of this?

Jan 7, 2006I would like to know how to write javascript such that, a part of it isnt considered as script, & rather as HTML. Code:

AJAX, Eval(), And Javascript Within Javascript
Apr 28, 2006Ok so, this is my purpose:
- to be able to load asynchronously (via AJAX) some javascript ads (like google's or adbrite) so as to make them be loaded in the background, then update the page after the ads have loaded via innerHTML
Why?
-Because 90% of the time in my newer sites, javascript ads are the major offender in terms of speed of page rendering
My problem:
Via ajax, I can call a php file that retrieves some javascript and outputs it, XMLhttprequest returns those javascript lines, but they don't render in the page, since they miss the whole page loading, and are apparently not parsed
For example, let's say I call a php file via ajax, and it returns the output into a variable named "text" containing "document.write('hello')"
if I use xxx.innerHTML=text, nothing happens
My 1st solution:
Passing those javascript lines to eval() [like eval(text) ], but this produces a second problem, that I couldn't solve (probably because of my lack of knowledge in javascipt):
if I eval the code, it deletes my current page and renders a new one
for example, if I parse a document.write, my page disappears, and a new one is rendered with the document.write text
What I want is basically to make that "document.write" appear inside a div in my page, adding to the content (and not overwriting the whole page), much like what happens when using innerHTML
Is this even possible? How would you go about it?
I tried xxx.innerHTML=eval(outputfromphpfile) but it overwrites my whole page...
