jquery show隐藏每个div onclick [英] jquery show hide each div onclick

问题描述

我有一个通过asp.net生成的动态div数。我需要通过单击其标题来显示每个div内容。我试过这个{

I have a dynamic number of divs which generated through asp.net. I need to show each div contents by clicking on its header. I have tried this {

 $(function () {
            var myHead = $(".toggle-container").find(".toggle-header");
            var myBody = $(myHead).parent().find(".toggle-content");
            $(myHead).click(function () {
                if ($(myBody).css('display') === 'none') {
                    $(this).children('i').removeClass('icon-chevron-sign-down').addClass('icon-chevron-sign-up');
                    $(this).parent().find(".toggle-content").slideDown("slow");
                } else if ($(myBody).css('display') === 'block') {
                    $(this).children('i').removeClass('icon-chevron-sign-up').addClass('icon-chevron-sign-down');
                    $(this).parent().find(".toggle-content").slideUp("slow");

                };
            });
        });

但它仅适用于第一个标题，其余标题不会折叠它的子内容。这是迄今为止我尝试过的 JsFiddle 链接。任何人都可以修复吗？

But it's working only for first header and rest of the headers doesn't collapse it's children content. Here is the JsFiddle Link what I have tried so far. Can anyone give a fix?

推荐答案

问题在于你是如何找到要显示/隐藏的内容的。你需要找到与点击的标题相关的内容你的代码 var myBody = $（myHead）.parent（）。find（。toggle-content）; 应该进入点击处理程序，因为 var myBody = $（this）.next（）

The problem was how you were finding the content to be displayed/hidden. You need to find the content related to the clicked header you the code var myBody = $(myHead).parent().find(".toggle-content"); should go inside the click handler as var myBody = $(this).next()

 $(function () {
     var myHead = $(".toggle-container .toggle-header");
     $(myHead).click(function () {
         var myBody = $(this).next()
         if ($(myBody).css('display') === 'none') {
             $(this).children('i').removeClass('icon-chevron-sign-down').addClass('icon-chevron-sign-up');
             $(this).parent().find(".toggle-content").slideDown("slow");
         } else if ($(myBody).css('display') === 'block') {
             $(this).children('i').removeClass('icon-chevron-sign-up').addClass('icon-chevron-sign-down');
             $(this).parent().find(".toggle-content").slideUp("slow");

         };
     });
 });

注意：上下箭头仍然无效，因为你需要使用 find（）而不是 children（）

Note: Still the up-down arrows are nor working because you need to use find() instead of children()

但它可以简化为

jQuery(function ($) {
    var $heads = $(".toggle-container .toggle-header");
    $heads.click(function () {
        var $this = $(this);
        $this.find('i').toggleClass('icon-chevron-sign-down icon-chevron-sign-up');
        $this.next().slideToggle("slow");
    });
});
