Jquery - 加载动态内容时悬停效果不起作用 - 带有hastags的URI

Jquery - Hover effect not working when loading dynamic content - URI with hastags(Jquery - 加载动态内容时悬停效果不起作用 - 带有hastags的URI)

问题描述

我目前正在做网站的前端工作.我正在使用 jquery 来创建动态内容.

I am currently working the front-end on a website. I am using jquery in order to create a dynamic content.

我的问题是，当我键入我的 URI (localhost/jquery/myfile/) 并加载 index.php 时，我的 jquery 脚本可以工作，但是当我单击导航栏并且我的 #index.php 被放置在URI (localhost/jquery/myfile/#index.php) 我的一个 js 脚本，一个具有悬停效果的脚本不起作用(但我所有的其他 js 文件都可以工作，例如我的导航菜单脚本，其中包含悬停效果以及).

My problem is that when I type my URI (localhost/jquery/myfile/) and the index.php loads, my jquery script works, but when I click on my navigation bar and my #index.php is placed in the URI (localhost/jquery/myfile/#index.php) one of my js scripts, the one with the hover effect, doesn't work (but all my other js files work, such as my nav menu script which includes a hover effect as well).

我进行了研究，发现当加载新的 URI 时，悬停效果停止工作.

I have made my research and found out that when the new URI is loaded, hover effect stops working.

如果您能帮我找出发生这种情况的原因，我将不胜感激.

I would really appreciate if you could help me find why this is happening.

**我的动态菜单工作正常，问题是 ext.js 脚本不工作.

*edit:*My dynamic menu is working fine, the problem is that the the ext.js script is not working.

推荐答案

如果您使用的是最新版本的 jQuery (1.7+)，请尝试使用 on()，如果是旧版本，请尝试使用 delegate()，而不是仅仅悬停()

Try using on() if you are using a recent version of jQuery (1.7+), or delegate() if its an older version, instead of just hover()

像这样:

$("#main-content").on("mouseenter", "#items .item", function(event){
// your function
}).on("mouseleave", "#items .item", function(event){
// your function
});

参见:http://api.jquery.com/on/
