Disabling a button/link with JQuery

08 Aug 2011

This post is old. nowadays you can disable buttons/links with some css code.

As you probably know, if you want to make a sexy button, you need to implement it with a link.

Here is a simple search I did with Google, and an example for it I found right away

Note - that the post does not explain how to disable/enable the button... And who wants a button that cannot be disabled?

Disabling a button can be very useful if you want to make sure the form is filled properly. Simply enable it once all the details are ok.

However, disabling a link is impossible.
Instead - you need to implement "onclick" with "return false".

At first, I thought about using blockUI - a cool JQuery plugin I recently discovered.
But it seems it does not block anchors - I could still click the anchors.

Solution Step #1

A really good solution would be to change the opacity to 0.4 and add "onclick" as required.
This works great.

And at first I used this technique in a Utils function... cool ain't it?

However, soon enough, I had to have it as a JQuery prototype function (method).

Solution step #2

Adding this solution to JQuery was easier than it looks

/** Adding "disable" on expand button**/



As you can probably see, it's quite easy to add "isButtonDisabled" method to the deal.


What I really wanted was to modify only the Anchor tags.
So I tried to do something like

$.fn.extend(AnchorHTMLElement.prototype, { ... } )

But it didn't work. If anyone has any idea why, please let me know.
This is also the reason why I have such specific names for the methods, and not just "enable"/"disable"
