Jquery expanding divs by class

I am having trouble with an if statement in the following code, I am trying to trigger an event if a div has a class, which is added and subtracted in a code. Is this the correct way to do this? Because it isn't working?

$(document).ready(function() {

    $('.content_accrd').css({
        "height": "0px"
    });
    $('.content_accrd:eq(0)').addClass("open").css({
        "height": "110px"
    });
    $('.paneltop:eq(0)').css({
        "background-开发者_如何转开发position": "0px 0px"
    })
    $('.paneltop').click(function() {
        **if ($(this).siblings('.content_accrd').attr('class') != "open")** {
            $(this).addClass("open").css({
                "background-position": "0px 0px"
            }).siblings('.content_accrd').animate({
                "height": "110px"
            }, 200)
        } else {
            $(this).reomveclass("open").css({
                "background-position": "0px -21px"
            }).siblings('.content_accrd').animate({
                "height": "0px"
            }, 200);
        }
    })
})

You want to use the hasClass function:

$('.paneltop').click(function() {
    if ($(this).siblings('.content_accrd').hasClass('open')) {
        $(this).removeclass("open").css({
            "background-position": "0px -21px"
        }).siblings('.content_accrd').animate({
            "height": "0px"
        }, 200);
    } else {
        $(this).addClass("open").css({
            "background-position": "0px 0px"
        }).siblings('.content_accrd').animate({
            "height": "110px"
        }, 200)            
    }
})

Swapped the order to avoid having to use ! :D

removeClass was spelled wrong as well.

Change to:

if ($(this).siblings('.content_accrd').hasClass('open'))

You can try the .hasClass() method:

if ($(this).siblings('.content_accrd').hasClass('open')) {

You should be doing it like this:

if ($(this).siblings('.content_accrd').hasClass('open')) {
    // ...
}

However, that leaves open the question: what is this test supposed to do? Test any sibling for having that class? One specific sibling? You should make that explicit.
