Need to use jQuery.find to find element with specific style

Question

Right... I need to find all < ul style=\"display: block;\"> elements, so that I can set it do display:none.

I think I\'m on the right path here... but not quite t

Answer 1

You may be able to use the attribute selectors, and the 'contains' option

$('#adminMenu li ul[style*="display:block"]').hide()

This essentially says 'any ul who's style attribute contains the text display:block'

Answer 2

$('#adminMenu li').find("ul:visible").css('display', 'none');

or

$('#adminMenu li').find("ul:visible").hide();

or

$('#adminMenu li ul:visible').hide();

to name a few ways

Answer 3

That's tricky as stated but is solvable other ways. The easiest is:

$("#adminMenu li ul:visible").hide();

assuming items are either hidden or not. Of course, considering you want to hide them all why not just:

$("#adminMenu li ul").hide();

Try and avoid changing CSS style directly. It's problematic. It's hard to reverse and as you're discovering hard to search for. Use a class instead:

#adminMenu li ul { display: none; }
ul.block { display: block; }

with:

$("#adminMenu li ul").removeClass("block");

or

$("#adminMenu li ul.block").removeClass("block");

Answer 4

Don't know how to do it in one line, but here's how you can do it in a couple more:

jQuery('#adminMenu li').find("ul").each(function (){
  if($(this).css("display") == "block"){
    // do something
  }
});

If what you want is to handle all visible elements (instead of only the display: block ones), you could try the :visible selector instead.

Answer 5

You can use filter. (http://api.jquery.com/filter/)

So you can do as below.

$('ul').filter(function() {
    return $(this).css('display') == 'block';
});

Answer 6

You coud use the fadeOut() or slideUp() methods for a visual effect:

jQuery('#adminMenu li').find("ul").fadeOut('fast');

jQuery('#adminMenu li').find("ul").slideUp('fast');
