通过jquery选择具有类名称的特定字符串的所有元素

Question

This is my HTML DOM:

<div id="d1" class="Addable"><span class="yak-bak-nak vok-do-maria"> <p>Goola1</p>
<span>volaa</span></span></div>

<div id="d2" class="Addable"><span class="yak-bak-val vok-do-maria"> <p>Goola2</p></span></div>

<div id="d3" class="Addable"><span class="vok-do-maria yak-bak-nak"> <p>Goola3</p></div>

<div id="d4" class="Addable"><span class="vok-do-maria yak-bak-nak"> <p>Goola4</p></div>

<input type="button" class="Doop" value="Do" />

So I want to remove all divs that class names start with "yak-bak" that means all of the above.

so I try this script:

$('.Doop').click(function () {

    $('span[class|="yak-bak"]').parent('div').remove();
});

but just d1 and d2 remove and d3, d4 remain because the yak-bak class come as second also I try this:

$('.Doop').click(function () {

    $('span[class^="yak-bak"]').parent('div').remove();
});

So what is your suggestion? where is the problem?

Answer 1

To target elements with multiple classes, where one of then starts by "yak-bak" at the beginning of the attribute class, or at the middle of it, you can use:

JQUERY

$("div[class^='yak-bak'],div[class*=' yak-bak']").parent('div').remove();

This will select elements where the class starts by "yak-bak" and elements that contain a class stated by "yak-bak".

Answer 2

$('div').filter(function() {
  return $(this).has('span[class^="yak-bak"]');
}).remove();

DEMO

Or

$('div').filter(function() {
  return $(this).has('span[class^="yak-bak"], span[class*=" yak-bak"]');
}).remove();

But First one will enough.
