jQuery选择除一个ID之外的所有类

Question

I need to select all divs of a certain class (jqx-slider) excluding one ID (#str_prg) - something like:

$("div.jqx-slider :not(#str_prg)").each(function () {
.....
});

What is the correct syntax for that?

Also, would it be faster and more effecient code, if I add a "if" condition inside the loop - like

if($(this).attr('id') ! = "str_prg"){

}

Thanks!

Answer 1

You are using an descendant selector between the class selector and the not selector, which is invalid for your requirement

$("div.jqx-slider:not(#str_prg)")

when you say $("div.jqx-slider :not(#str_prg)") it selects all descendants of elements with class jq-slider except the one with id str_prg

Answer 2

尝试像这样删除不必要的空格字符：

$("div.jqx-slider:not(#str_prg)")

Answer 3

Remove the space, as it would cause you to select children, instead of the element itself.

$("div.jqx-slider:not(#str_prg)").each(function() {
    .....
});

For the second part of your question, it would be better to just use the CSS selector instead of a JS loop.
