DOM attribute change debugging
(4 answers)
Closed 9 years ago.
I have a large website in development with a large amount of JS in different files. I have come across an issue where something is removing a class from the DOM. I can see it when I view source but not in Firebug.
Normally I would place some alerts/console.log calls with the hasClass value but because I have no idea where to start I wanted to know if I can trace the change back when it occurs somehow?

Firebug lets you set a breakpoint and single-step through your code. This should make it clear where the issue is happening.
that specific class name must be in use in that hidden function that remove it, right?
so either grep for it on posix-based system, or, if you are using Win system, use your IDE "search-in-files" function to trace that modification.

How to really isolate stylesheets in the Google Chrome extension?
(5 answers)
Closed last year.
I'm making a browser extension. It creates some UI on the page. In the UI, there are elements which are being forcefully modified by css depending on a website is opened. Aside from making it ugly, it also might break the whole UI!
The question is how to protect my poor elements from css terror?
There are multiple options such as iframes, extremely specific classnames, and adding the !important field everywhere. But your best bet might be to use a shadow DOM which allows for a hidden DOM tree attached to the regular (perhaps that third party website) DOM.
I've seen another thread on this post that might provide more detailed answers.

How to handle JavaScript being disabled in AngularJS
(2 answers)
Closed 8 years ago.
I have learned angular.js, and it's awesome , i'm impressed. i want to use it in my website, but what if our some of user has disabled JavaScript on there browser, they should still gonna see my website content ?????. i'll appreciate your help.
In most cases when js is required, you should add noscript which will be displayed when js is disabled. In that tag you need to warn user that he/she should enable js.
In addition to other answer, I am quoting from Angular book:
Not everyone’s browser supports JavaScript. Let everyone see all of your content and use your app without needing to execute code in the
browser.
The world has changed since these concepts were born. Point #1 is no
longer true for any interesting population. If you’re running a
browser without JavaScript, you’re rele‐ gated to sites created in the
1990s
Or make a div with a warning/notice text (maybe in center of page), and hide that div in js (first thing in your code)
So, if the user does not have js enabled, they will see the nice warning

can view source be disabled by a website?

Closed 8 years ago.
Actually I want to protect my source code of my website from everybody.
so I want to disable all sources of finding the code like: Ctrl+U, Ctrl+Shift+I,F12 and menu of browser.
It is impossible to hide your source code. You could install a script to prevent right-clicking or encrypt your code with JavaScript, but that won't stop anyone that knows anything about web development from finding it.
This will never work, and your effort is better spent elsewhere.
At the very least, a user can use a web proxy like Fiddler to easily retrieve the source code.

How can I update the title of the tab in the same way GMail/Facebook does?
How is it possible to update my browser title value, like Facebook and Yahoo, to show a number that represents notifications/pending items/new messages etc.
Right now, my Facebook page title/tab reads [ (3) Facebook ], which indicates I have 3 unread notifications.
How is this possible? I reckon it uses JS and AJAX but I maybe wrong. Has anybody got any snippets, links or suggestions that will get me started in this?
It's a really nice feature but don't seem to find many websites using it, neither can I find any decent tutorials or examples.
Many thanks
It's just a property of the document object
document.title = "some string";
Use whatever logic you like to determine what information you want to put in there.
Be aware that it will produce some really odd bookmark names.
You just need to change title of your page using javascript.
if you are using jquery, it is as simple as -
$('title').text('someText (3)')

You can use the <noscript> tag:

Know this is an old thread, but just thought it add my own solution. I have javascript controlled <div> and on a browser where javascript is disabled, none of these are show so:
Have a standard <div> in center of page saying “please enable javascript to view or click here for non javascript page”
Set the z-value to -1
Have all javascript controlled <div> and set with a white/whatever background and a z-index value to 0 or higher
The javascript controlled <div> will cover the message if enabled, and show it if not.
Hope that this gives one or two of you a few ideas. Although this was specifically for my site, you may find that thinking out the box may help you too.
