JQuery get specific classes but not others

I have a div that looks like

<div class="draggable resizable abc table shadow"></div>

Clans do not have a specific order. If I do $('div').attr('class'), then I will get a list of all the classes for this div. I only want to get classes that are not resizable, draggableor table. In this case, I want to abc shadow. How to do it.

var all  = "draggable resizable abc table shadow";
var some = all.replace(/(?:^|\s)(resizable|draggable|table)(?=\s|$)/g, '');

console.log(some);
// " abc shadow"

console.log(some.replace(/^\s+|\s+$/g,''));
// "abc shadow"

console.log(some.split(/\s+/));
// ["", "abc", "shadow"]

Note that you do not need a second one replace(you do not need to highlight leading and trailing spaces) if all you need is a line corresponding classNameto the to setting .

, , :

$(...).removeClass("draggable resizable table");

( ):

var ignore = {resizable:1, draggable:1, table:1};
var all = "draggable resizable abc table shadow".split(' ');
for (var subset=[],i=all.length;i--;) if (!ignore[all[i]]) subset.push(all[i]);

console.log(subset);
// ["shadow","abc"]

console.log(subset.join(' '));
// "shadow abc"
