I created a website and it works perfectly fine on chrome but on IE the js doesn't seem to be working. I'm not sure what's going on because I added a < noscript > tag to check if JS wasn't loading but it doesn't show up (which means JS is running fine), and I went to some of those "check if JS is enabled on your browser" sites and they all said it was working.
Then I checked the settings and it had it enabled as well. So JavaScript seems to be working but the JS on my website (such as smoothly scrolling down when I click a link in the navbar) isn't working.
Anyone have any reasons as to why? Am I forgetting to put an extra tag or something. Any help is appreciated
document.querySelectorAll returns a NodeList NOT an array. forEach on a NodeList is not supported in IE. See https://developer.mozilla.org/en-US/docs/Web/API/NodeList#Browser_compatibility
It should work if you replace the forEach with a For loop or use the Array.prototype.forEach (which is also documented on the page in the link above)

The current project I am working on builds a page's javascript code based on some conditions. All the code works but when I go to the Developer Tools to see it, it is not showing. Or more like it is truncated and 3 dots added at the end.
It seems to be a change with the recent update. It is extremely annoying to not be able to see everything. Does anyone know how to make it show everything? If it helps, I'm working on a mac. Thanks.

If you right click on the <script> tag and select "Edit as HTML", you'll be able to access the whole script, without the hyphenation.
This answer https://stackoverflow.com/a/10929430/749227
to this question Is possible to debug dynamic loading JavaScript by some debugger like WebKit, FireBug or IE8 Developer Tool? is spot on for debugging dynamic scripts.
The issue I am facing is that I have a page that has a script on it, and after it loads an ajax request fires which returns with some HTML and a script that get put into the page. With the //# sourceURL=myDynamicDocumentFragment.html bit added, I can debug the dynamic script just fine.
But once it's loaded, then the other script that is part of the outer page that initially loaded goes off the rails. I can set breakpoints on blank lines and can't set them on legitimate lines. The debugger will stop on them but it won't be at the place in the code where I'd expect.
What it appears to be is that the dev tools window is showing the original script, and the debugger itself is running on something else - some updated version of code that includes both the outer page's script and the dynamic script that was added later. Or maybe it just hiccups with respect to line numbers it's displaying and what those map to in the code it's actually running.
I wish I had a good simple code snippet to demonstrate the issue, but I don't. Has anyone seen this, and does anyone know of a way to have Chrome 'refresh' the dev tools scripts/debugger without refreshing the page? (it has to be w/o refreshing the page since things work fine when the page loads - it's only after the dynamic script is dropped in that the wheels come off)
Note: I've tagged with Chrome since that's what I'm using (v 38). I don't know how other browsers fare.
You can find scripts injected into head or evaluated, here is a break point added on youtube evaluated (another js file).
You can find this in chrome as well, adding console.log (click on message shown), and voila you have source code you can add break points.
Here mozila print debugging/breakpoint over evaluated script on utube page:
Update
Sorry, I understand chrome was out of the scope, my engrish :)
How I did debugging on chrome over injected scripts, but there are cases when you cannot attach to execution if script is active (page load plus few milliseconds), you need to search for workarounds.
Added this at the begin of the script injected:
//# sourceURL=jseinjectedsource.js
console.log("evaluated");
and voila console:
Better check this way better than my explanation chrome developer
Check to see if your script is using a source map (if you're using TypeScript this is typically on by default for VS projects).
I've found Chrome to be really bad with source maps, often refusing to update them, or stop displaying them after the source map line is removed from the code.
Here is my problem. First I load the site and everything works fine. Then I click on a link and it calls Ajax for new page. Data that is returned contains HTML and Javascript. Some javascript functions works fine, like click function. But google maps don't want to load, mouseover functions works but doesn't want to show/hide ( btw alert function works).
But there is a trick. If I open Developer Tools (right click -> inspect), somehow google maps shows up and functions start working.
I know this is a bug, does anyone know how to go around it?
And there is a Warning: (2) event.layerX and event.layerY are broken and deprecated in WebKit. They will be removed from the engine in the near future. I have jQuery version 1.7.1.
The problem was empty <progress> tag.
When I removed it from my form, everything was working normaly. Strange.
i don't face this problem while working on localhost only when I access the page using the ip address of my system this happens and it only happens with IE!! (works on all other browsers)
by the way i'm using Tomcat V6.0.0.29, IE8
I tried debugging the JS code using IE developer tools debugger, ofcourse when I open using http://localhost:8080/ everything works perfectly fine, but when I use http://myIP:8080/ this loop is giving a problem :-
$('#someId > div').each(function(){...});
As in this loop doesn't run at all, it just kind of skips it. I have checked the IDs they are fine moreover its working in localhost why should it give a problem when I access it using my IP?
Note :-
a. (correction) The problem is only there in IE7, it works perfectly in IE8.
b. As it turns out something weird is happening! i'm using IE8 when i open this webpage using localhost the developer tools shows its working in IE8 standards but when i use the IP address to access this page the developer tools shows its working in IE7 standards. When i changed the standards to IE8 it worked (using the IP address)!
c. But the problem is why the hell is it not working with IE7!! As in everything works except the loop mentioned above.
Finally i came to know what was causing the problem in IE7. Consider the below situation:-
<div id="div1">abc
<div id="div2">def
<div>hjs</div>
<div>zyx</div>
</div>
<div id="div3">xsj
<div>ask</div>
<div>iue</div>
</div>
</div>
The jquery i had written for traversing these divs was something like
$("#divId > div").each(function(){..});
Now for the first level div that is traversing the divs directly inside the div with id "div1" worked perfectly in IE7, but when i did something like:-
$("#div2 > div").each(function(){..});
This worked in all browsers (even in IE8!!) but not in IE7. This is because apparently IE7 requires the exact child selector for divs.
So for IE7 something like this needs to be written:-
$("#div1 > #div2 > div").each(function(){..});
for traversing the divs inside the div with id "div2"
So the problem was cause just by my lack of knowledge about IE7!!
sorry n thanks guys!
The culprit being IE it could turn out something as evil as the browser not caching the page when loaded from localhost, but reading it from cache when using the ip. Make sure you load the page to empty cache from your ip.
Check to see if your script is loaded when using your IP address. Sometimes browsers don't load scripts on special situations (for example when you want to load a script from an http source into an https page). Also you should check IE's security configuration.
To check whether your script is loaded and executed or not, simply put an alert('loaded') statement at the beginning of your code.
This may due to the group policy of your company for forcing Intranet sites using a specific version of IE in compatibility mode. I experienced exactly the same issue when I introducing some IE10+ Javascript libraries to my page.
To work around this you can either ask your company IT for changing the policy or force the browser to not using a compatibility view with the following tag.
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
More details for this tag can be found with the topic below.

We have an automatic slider on this website, http://www.realcapfinancial.com and it has been working on all browsers. IE9 doesnt seem to work. It comes up with and error, no object line 298... character 2 etc. I forget what it says but I can't check it again since I'm at work using a mac.
Any help is perfect, thank you
The element with id calcclick is only added after the Resources tab is click. However, this element is already adressed (on line 298) on page load.
