mouseover not working in ie7 - javascript

Having problems in IE7.It does not show me the "mouse over- drop down".
This "mouse over" was working well till yesterday also works in FireFox.
There a table that displays all the current documents.When one does a mouse over on a given document,it displays a list of options in form of a dropdown.
Can it be corrected in IE settings etc?
I am not talking about the javascript here , only the user settings.I am strictly the end user in this case.Also i tried downloading IE8 and it stopped in between.Hence I checked the ActiveX settings in IE and it was enabled.
Kindly help.

Your question seems well-founded, but it's difficult to discern what the question is exactly. Could you please elaborate? Source code may also help.
If you'd like to go a more DIY route, try throwing your code at JSLint. It will magically surface errors you didn't see.

Sitecore generates a lot of temporary and debug code files. This could be the problem. I would try deleting all of the temp/debug files, and see if that helps. They are scattered throughout the site, so you have to hunt for the debug directories.
However, I do see a lot of WEIRD JavaScript things with SiteCore. Sometimes I will load the content editor, and it wont work because of JS errors. I clear my cache and refresh and it works fine. But nothing in the JavaScript should be changing, since it would be the scripts from the vendor. I don't go in and change JS. Maybe they are generating JS somewhere.

Why is some of my JQuery loading right away, and other parts are taking over ten minutes to load on a page (or never loading)?

I'm developing a web-page, basically from scratch. I have a .html file, .css file, and .js file that includes only JQuery. I am only running this locally on my own machine, and for some reason, now only some of my Javascript loads. For instance, I have some hidden s that when hovered over, they are displayed with JQuery calls. These seem to work fine as they always have. I have a scrolling sidebar that has hidden sub-menu items, and this usually loads fine as well. I have a hidden div that displays a definition list on a button click, and when you hover over the , the should slideDown. If I wait about 10-15 minutes this will start working. But obviously that is a problem.
Also, in Chrome's 'Developer Tools' I don't see any errors under the sources tab. I checked the 'Pause on caught exceptions' box, (this is where my knowledge ceases) and in jquery.min.js:formatted, it pauses and highlights e.querySelectorAll("*,:x"), and when I resume, it does the same thing here, c.call(e, "[s!='']:x"),
Hoping someone can not only answer my question, but explain what's going on here in the caught exceptions. By the way, I did not write jquery.min.js:formatted.
Thanks in advance!
I copy/pasted my link to fontawesome and the JQuery library is up to date. Someone said something about the possibility of an infinite loop, but I'm not keen on what that is, I'll look into it.
Showed some code above. Not sure how helpful it is.
My expected output would obviously be for my JQuery to work, but it is not.
No error messages in the Console.
I actually figured it out, sorry I can't post working examples bc it's proprietary.
I was missing a closing } bracket...
But the way I figured this out was through opening up Chrome's 'Developer Tools' and switching into the 'Sources' tab.
- From here, underneath the stop sign with a pause symbol, it displayed exceptions in the code where something breaks.
This was much easier than scanning the code with my eyes. Sorry if this was a basic answer, it really helped me a lot.

Using Javascript to sort table properly?

I've been working on this website on my computer for the past several weeks, but have had it a point that I just can't figure something out with my table sorting. The site itself runs off PHP but I've duplicated the HTML output to make it easier for you guys to help me diagnose what the problem is.
Here's a link to the Working Page: http://privateservercloud.com/working.htm
Here's a link to the Not Working Page: http://privateservercloud.com/not-working.htm
If you go to the Working Page, you'll see that you can click on any of the headers of the table and it will sort them. However, if you go to the Not Working Page, you'll see that this doesn't happen.
I'm trying to figure out what's missing or coded incorrectly and causing this to happen. I've uploaded all of the HTML, CSS, and Javascript that's running this part of the site so you can see how it's all working and hopefully that'll make life a bit easier for anyone that can help.
So... does anyone see what I'm doing wrong or know what needs to be fixed?
I load the not-working example in Firefox with Firebug and get the following:
TypeError: document.getElementById(...) is null
...for(var e=0;e<menuids.length;e++){var t=document.getElementById(menuids[e]).getE...
in dropdown.js line 1.
The debugging tools really are your friends. If you don't want to use Firefox, you can do the same thing with the development tools in Chrome.
I find errors when I run rhe validator at http://validator.w3.org and a pile of CSS errors at http://jigsaw.w3.org/css-validator/
When things don't work right, validate the HTML, which at least mostly assures you have a valid DOM. Then validate the CSS and use the JavaScript console in your favorite browser's debugger.

Diagnosing Perplexing CSS errors

My website that has been up for a month now without any problems.
This morning everything was normal until I opened up the developer tools in chrome and when the cache refreshed the website was discombobulated!
Opening the website in Firefox I was able to get an idea of what is going on, but still have no clue how to resolve it.
Opened the page in Firefox before refreshing the cache
Notice in the css log how there are no errors.
Refreshed the cache
None of the css is applied and as you can see lots of css related errors.
I went through all my css/script files and none of them have been changed in the past 24 hours.. They all seem to be the same files that have been working perfectly for the past month.
Can anyone give me an idea of what might be going on here? Is it a server issue? Appreciate any ideas/answers to help me get to the bottom of this.
Click on the arrow next to the CSS button in FF's browser tools and deselect warnings.
What you're seeing are warnings related to things like vendor related prefixes.
In general, if warnings are serious enough that action is required, they would be errors. In my opinion you can safely ignore them.
See here: Should FF Error Console "Warnings" be taken seriously if page is not "broken"?
Looks like your site has lots the correct paths to the stylesheets. Have you changed your head or xml recently?
Solved
Another developer updated our bootstrap files from 2.3.2 to the latest version of bootstrap.. And for some reason the modified dates for the files did not change on the server.
Anyway because this issue is so isolated and the question probably won't be of any help to anyone in the future i'll remove it.. But leave this solution up for a few hours just as a FYI to those who have answered/commented on the question.

Eclipse keeps jumping to the start of the document

I have been using Eclipse for some weeks now and I start getting used to it.
However, one thing really annoys me:
When editing JavaScript (I didn't try any other language yet), the editor window keeps jumping to the start of the document I am editing.
This mostly happens when the code currently contains syntax errors and mostly while / after deleting lines.
Especially constructs like { = and sometimes unterminated strings / comments seem to cause this problem.
When it happens, only the view scrolls to the top of the document - the cursor stays where it was before the "jump" occurred.
Anyone having an idea on how to fix this?
I believe the problem described above is related to this bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=318095
The work around is to disable the "Link with Editor" option from the Project Explorer. Which is to say make sure the icon with two arrows facing in opposite directions at the top of the file tree is not enabled. Disabling this option resolved the issue for me.
Looks like a problem with the implementation of the JavaScript editor. Most probably the jump occurs when the JavaScript-Parser is not able to parse your document and throws an exception. You might consider to report a bug to the eclipse project (maybe there is already such a report?).
As a workaround you might consider to adapt your way of typing the code a bit. Try to write the code in a way that does not confuse the parser (for example it might help to immediately close a newly created comment and THEN write the content instead of open the comment, write the content and finally close the commend). Same for strings, blocks ...
I am having the same problem. I had this line of code in my file and I could consistently reproduce the issue:
$.preload(preloadImages
, {
base:assetsUrl+'b/images/',
ext:'.png'
});
I changed it to the following and I no longer have the problem.
$.preload(preloadImages, {
base:assetsUrl+'b/images/',
ext:'.png'
});
I get this Phenomenon, when i'm editing in a Java-Class while still residing in a Debug-Process. The Debugger recognises the Change and reevaluates the Code and jumps back in order to be able to reexecute only the changed Code.
Hii i got solution goto
Window->Preferences->search autosave
and disble it and hit apply and close button.
this worked for me !

LinkButton sometimes requires two clicks

I have an ASP.NET 4.0 Web Forms app and I'm using jQuery to do most of the JavaScript. The problem I'm having is that some of the links sometimes require two clicks for them to do anything.
Seemingly this happens at random and I have been unsuccessful in reproducing the problem in any kind of repeatable fashion, also there don't seem to be any JavaScript errors, so that's probably not the issue.
I'm at a loss as to what might be causing the issue. What might it be?
Without a view of your Javascript, HTML or backend code, there's not much I can suggest as to what might be causing the problem.
However, if you have Firebug installed, you could use that to see what clicking the button is doing each time and go from there.
Also... what is it supposed to do? What does it do the first time? These are questions that will need answers before debug assistance can be provided
