Question

I want to remove unwanted nesting.

How can I select from DOM, elements with this form:

<div style="display: block;">
..
</div>

It seems like a tight filtering like:

var unwanted_nest = $('.webform-client-form').find('div:not([id])').filter('div:not([class])');

will only display forms like: ..

Answer 1

try this

$('div[style="display: block;"]');

however this selects all the div with attr style= display : block if this what you want
