Apply JS To Websites - Recommend Any Q And A Style Tutorials?

Sep 13, 2011

I have been studying Javascript for a couple of months now, but have kind of come to a dead end in terms of in what instances will I need to apply JS to websites and can anyone recommend any Q and A style tutorials, to test myself,My current knowledge (which is very basic) so far contains being able to:

Write a prompt
Write a confirm
write a basic for loop
write a basic while loop
write an array

Any guidance on scenarios to use to demo JS or a good tutorial website for real world scenarios,

Apply Style Changes To A Whole CSS Class

Sep 19, 2005

I would like an event to trigger a change the style of all the elements that
belong to some CSS class.

I know it is possible to change the class of an element, for example with:

<script language=javascript>
function changeclass()
{document.getElementById(id).className="class_id";}
</script>
<input type=checkbox onclick="javascript:changeclass()">

But this can only change one element. I would like to change the
"property:list" pairs of a CSS class, so that changes can apply to more
than one element.

Is it possible with javascript?

Apply A Style Expression During Runtime?

Feb 10, 2009

I need to set the position of an element to fixed using JavaScript at runtime.
Sadly, IE6 does not know this value, so I want to use the following workaround:

Instead of setting the position to fixed, I set it to absolute for IE6, and the top value needs to be the following expression:

Code:

top: expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px');

Sadly I have no idea on how to apply this expression to myFixedObj.style.top! I tried it using

Code:

myFixedObj.style.top=expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop) +'px');

and

Code:

myFixedObj.style.top="expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px')";

Apply CSS Style For Table Row If Radio Button Is Clicked

Jun 6, 2007

I am trying to make it so that the style "RowSelected" (embedded
below) is applied to the table row from which the radio button is
selected, and then removed when a different radio button is clicked.

Right now, the below code kinda works. The javascript was copied from
an example on a website from which I forgot the URL. It only applies
the style properties to the label text, and not to the row. Code:

Using Javascript To Apply One Element's Style To Another Element

Jul 27, 2007

Code:

test.div.style.backgroundImage=test.div2.style.backgroundImage;

It works if I specify the actual background image within the function, so I know the image is there, and I know it's been properly assigned to div2, but div1's background image doesn't change.

Why Websites Are Restricting Using Scripts On IE

Feb 28, 2010

Ok im haviung a problem, im building a website and im building some javascript! My main issue is that whenever I use IE7, a small pop-up says "To help protect your security, IE has restricted this webpage from running scripts ... bla bla bla...

Block Certain Websites From Appearing?

Aug 22, 2011

is there a way using .htaccess or some other means that we can block certain websites from appearing when we do a google search of my wife's name? We contacted google and they denied our request to have these websites blocked. My wife has her own website she uses for her business. There was an .htaccess editor website that I visited that created the code after I specified the url of the websites we wanted blocked. Will this work and if so, after creating the .htaccess file what do I do with it, that is where do I attach it/post it? (this is the first time i've ever posted anything on a website. my wife and I are technophobes.)

Automatic Login To Websites?

Jun 6, 2011

From the term "automatic login" I suppose security (password protection) is not of key importance here. The guidelines for solution could be to use a Javascript bookmark (idea borrowed form a nice game published on [M&M's DK site][URL].. The idea is to create a javascript file and store it locally. It should do the login data entering depending on current site address. Just an example using jQuery:

[Code]...

Multiply the code blocks in your script, to add more sites in the similar manner. You could even combine it with `window.open(...)` functionality to open more sites, but that may get the script inclusion more complicated.

Note: This only illustrates an idea and needs lots of further work, it's not a complete solution.

This is the code I found on stackoverflow for automatic login to websites but it does not work.
I am doing exactly as told is ther anything wrong
