Applying css3 gradients with jQuery

问题

Eventually, I wish to dynamically alter gradients based on different things, but how do I get jquery to apply a css3 gradient?

 //works
 $(element).css("background-image", "url(http://www.google.co.uk/images/logos/ps_logo2.png)");  

 //doesn't work
 $(element).css("background-image","-webkit-gradient(linear,left bottom,right bottom,color-stop(0.50, rgb(194,231,255)),color-stop(0.50, rgb(255,255,255))");

 //doesn't work
 $(element).css("background-image","-moz-linear-gradient(left center,rgb(194,231,255) 28%,rgb(255,255,255) 28%");

What am I missing? I've also tried

 $(element).css({background: "-webkit-gradient(linear,left bottom,right bottom,color-stop(0.50, rgb(194,231,255)),color-stop(0.50, rgb(255,255,255)"});

Are these approaches not valid?

回答1:

Your second approach looks OK... Maybe you need to css styles for non-webkit browsers as well... Cross-Browser CSS Gradient

This works for me in Chrome

$('#block').css({
    background: "-webkit-gradient(linear, left top, left bottom, from(#ccc), to(#000))" 
});

Also have a look at: http://www.colorzilla.com/gradient-editor/

Another optionis to use the jQuery addClass method. This allows you to dynamically add and remove classes and therefore any formatting associated with that class including gradients.

回答3:

I'm using the hyphenated syntax in the JSON format (I always use the JSON format to be consistent). And it's working fine in both Chrome and Firefox.

For example:

$("#googleFeed div:even").css({
    'background':'-webkit-linear-gradient(top,white,black)',        
});

Here is a small piece of example...

$("p").css({background:'linear-gradient(red,blue,red)'});

回答5:

When using .css() in jquery, I believe you have to use the shortened versions of the attributes. For example, margin-left would be marginLeft

$(element).css("backgroundImage","-webkit-gradient(linear,left bottom,right bottom,color-stop(0.50, rgb(194,231,255)),color-stop(0.50, rgb(255,255,255))");
