IE8 Debugger: how to load external javascript files? - javascript

I have downloaded and installed IE8. I was playing around with the debugger, but I could not figure out how to load external javascript files. It displays the javascript from the main page, but I need to debug the script in the external files. I have googled various articles that show a screenshot of an IE8 debugger with a drop-down for selecting which script to debug, but my debugger does not feature this. Can anyone help me with this? Thanks.

Here is what I am seeing when I open up IE8. You just click the URL and it brings up a list of all scripts, which you can then click to load. If for some reason your browser is not showing the Script tab, maybe you should uninstall and reinstall it.

If the toolbar isn't wide enough (at least 800 at 92dpi) then the drop down arrow will be hidden (you can still click on the main area though). You can change that size by shrinking the size of the console on the right hand side their is a horizontal splitter bar between the script and console panes just click and drag on it.

Website not displaying correctly in Safari and Chrome

I'm a complete newbie here. I have been trying to learn to code a site with HTML/CSS/JAVASCRIPT.
I am using brackets to code the site. The site I am practicing with renders properly with all css and javascript.
However when I open the .html file into safari or firefox it does not display correctly. I think it is probably a css issue as the html elements are all there.
I have other sites that I have made before that don't have this issue and I can not see where I have gone wrong.
jsfiddle.net/fs4g55m2/1 I'm using fullpage.js as well. If you notice the navbar works perfectly well. It seems to be the css after it that is corrupted (once you get to the body tag).
If you think it is CSS (and you are linking to external CSS file) try look into the network tabs in your browser's developer console to see if it is properly linked. Check to see if requested css file throw back 404 status (not found) - usually highlighted in red.
In chrome or Firefox (not sure in safari) right click on your web page and click inspect element - then choose network tab.
Hope that helps

Disappearing images in chrome

In a landing page for a chrome extension, after the user installs the extension I show a popup that has an explanation on how to proceed. The popup contains images (that are served from a different CDN), the popup uses css animations and transitions when it appears.
Sometimes (not sure exactly when), even though the images are loaded (and visible in the dev tools) they are not displayed in the popup. I have tried changing it from css background-images to elements, I've tried updating the images src after the extension is added, and also to remove some of the animations, but it doesn't seem to fix this issue.

has anyone encountered a similar issue and knows how to fix or bypass it?
I have deal with same issue and only that works for me was removing -webkit-backface-visibility:hidden; from animate.css body tag

My Jquery slider is working locally but not on Web Server

I've a test website on http://insstock.info/xxx/
With two sliders inserted into it:
Nivo Slider
DIV Content Jquery slider (Exact below of Nivo Slider)
second slider is expected to flip the content one by one; the code and scripts are set accordingly!
It is showing no error in Chrome developer tool Console panel!
Can anyone Please help me to making this second slider work?
A couple of suggestions that I run through when I experience this behavior.
1) Clear the Chrome Cache
Chrome caches aggressively and frequently will return stale resources. You can clear the cache either by using Ctrl+Shift+Del, or prevent its use on the page by opening up Chrome Developer tools, clicking the gear icon in the bottom right, and checking "Disable Cache". Then reload the page with Ctrl+Shift+R. This will ensure you have the latest version of your resources.
2) Check the Network tab for any resources which are failing to load
3) Step through your code in the debugger to try to identify where things go wrong.
4) Start removing pieces more and more pieces of your code until you have a very small set that is exhibiting the issue. This is a great strategy for debugging generally, since it is much easier to debug something small than something big.

why does firebug debugging sometimes work and sometimes not?

I want to debug a javascript file that is embedded in the HEAD element.
I navigate to the site, see the code, and make a breakpoint:
(source: deviantsart.com)
But when I click on Reload, the script disappears and it doesn't stop at the breakpoint:
(source: deviantsart.com)
Debugging was working earlier so I know it works in general. What do I have to do so that Firebug always debugs my script?
I've noticed this behaviour before as well. It seems that it can happen if you refresh the page while the debugger is running (i.e. after you've hit your breakpoint and are stepping through code). This is far from conclusive, just something I've casually observed over time.
Also, I try to avoid having multiple tabs open with firebug active, as it seems to get confused.
Edit: just thought I'd add that I've seen this manifest itself in a few different ways:
the external script file does not appear at all in the scripts panel.
the external script file appears but firebug doesn't "see" it. You know this has happened because the line numbers beside the code where a breakpoint can be set won't be highlighted (used to be green but now appear to be just a darker shade than other lines). I've seen this happen with inline javascript on a HTML page (horrors!) as well.
the external script file is there, but you can only see a single screen full of code. Where "screen full" is the firebug panel viewport.
shut down firefox and then restart. sometimes firebug gets confused. also make sure you have the latest version.
You need activate the script tab
I'm not sure that having a <script> inside <head> (as opposed to, inside <body>) is actually legal HTML. If it's not, as I suspect, you can't fault Firebug for not supporting it well...!-)
The bugs in script processing that I know about are 1) jquery dynamic loading of scripts fails, 2) new Function() cannot be seen, 3) some kinds of document.write() cannot be seen.
Firebug processes script files in series with Firefox. This means that Firebug must be active when the page loads and it means that any exception in the path will cause the files to be mis-processed. If you opened firebug before loading and you still see problems, then the most likely fix is to install Firebug in a new Firefox profile. This causes you to get a completely fresh set of default options and you run Firebug without other extensions. As you re-add other extensions, look for problems in seeing scripts: then maybe you will discover what extension is interfering with the code path for processing scripts. I know this is a pain in the neck, but so is JS debugging without source ;-). We are working on testing with more Firebug and Firefox extensions installed to try to reduce these problems.
In our case it was the bundling of JS files.
It is not only FireFox, it is same for Chrome.
We moved the file out of the bundle and put it on the page where it needed to be referenced and it started working like charm.

Javascript problem in Chrome and Safari

I have a Javascript image switcher on my products page. It working perfect in IE and Firefox but both Safari and Chrome fails to load the script on some pageloads. A refresh seems to fix it but when changing product page or language it crashes.
The product page
Im using Wordpress and the script is varal.org/media/imageswitcher/
Thanks!
Anton
I did not experience any issues in either Chrome or Safari for Windows on your product page. Try this in Chrome, to check if the two scripts (imageswitcherconf.js and imageswitcher.js) are being loaded:
Press Ctrl+Shift+J to open the JavaScript Console/Developer Tools window.
Click the Resources tab on the top of the window.
Enable resource tracking/script debugging if you have to.
With the JavaScript Console/Developer Tools window still open, perform an operation that would normally trigger a crash, such as switching languages.
On the left side of the window, under the Resources heading, you should see imageswitcherconf.js followed by imageswitcher.js. (For me, they appeared fourth and fifth in the list, respectively.)
If the files aren't being loaded:
Are you behind a caching proxy?
Is your browser cache clear?
