Selecting all the divs with png background-image

问题:

How can I select in jQuery all the divs that have background-image: url(somepath/somename.png) in their style?

回答1:

There isn't a jQuery selector, but this might work:

$('div').each( function() {
    if ( $(this).css('background-image') == 'url("image.png")' ) {
        // do something here
    }
});

However, a more efficient method would be to make sure you only have a single class that uses that background image, then simply select $('.bgClass')

回答2:

Try adding a custom selector:

$(document).ready(function() { 
    $.extend($.expr[':'], { 
        hasMyImage: function(el) { 
            return ($(el).css('background-image') == "Url('somepath/somename.png')");
        } 
    }); 
}); 

Then to select:

$("div:hasMyImage");

回答3:

Use the filter function:

var matches = $("div").filter(function() 
{      
    return ($(this).css("background-image") == "url('somepath/somename.png')");
});
