What exactly are you trying to achieve? And why you have none without quotes in the second string? — David Jashi

Don't code with no sleep. Also have a look at how .css works: api.jquery.com/css/#css1. — Felix Kling

Assuming that objective is to determine if the display property is set to none:

jQuery('#container').css("display") === "none"
                           ^^^ Needs to be a string
                                    ^^^ Should be an equality operator

what does the -1 mean? and which are the other values? 1, 0 ?what do they represent

Quentin Over a year ago

The number is the position of the first character in the string that matches. If it is -1 there was no match.

Try this

if(jQuery('#container').is(':hidden')) {
    // code
}

You can use :visible selector in your case it will be something like this:

$('#container:visible')

which return true or false.

You are not enclosing the string in ''

if(jQuery('#container').css('display').index('none') > -1)

but is you are looking for whether the element is displayed then use the :visible selector

if(jQuery('#container').is(':visible'))
