Question

我有一个向下滑动切换div，其中包含标题，内容和切换打开按钮。我设置了一个小提琴，但div目前关闭完全阻止你再次打开。我喜欢关闭的div的高度是标题的高度。我怎么这个狐狸？

$(function(){

var open = 1;

    $(".toggle").click(function () {
        if (open == 1) {
            $(".box").animate({"height":"toggle"}, 1000);
            open = 0;
            $( ".toggle" ).addClass( "open" );
        }
        else if (open == 0) {
            $(".box").animate({"height":"toggle"}, 1000);
            open = 1;
            $( ".toggle" ).removeClass( "open" );
        }
    });

 });
