本文实例讲述了jQuery实现的简单获取索引功能。分享给大家供大家参考,具体如下:
<!doctype html> <html lang=\"en\"> <head> <meta charset=\"UTF-8\"> <meta name=\"Generator\" content=\"EditPlus®\"> <meta name=\"Author\" content=\"\"> <meta name=\"Keywords\" content=\"\"> <meta name=\"Description\" content=\"\"> <title>www.freexyz.cn 获取当前点击的元素在原来集合中的索引</title> <style type=\"text/css\"> li { height: 25px; line-height: 25px; background: rgba(0,0,0,0.5); border-bottom: 1px solid red; } a { text-decoration: none; font-size: 16px; } </style> </head> <body> <div> <ul> <li> <a href=\"javascript:void(0);\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" > <div class=\"index\"> 0 </div> </a> </li> <li> <a href=\"javascript:void(0);\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" > <div class=\"index\"> 1 </div> </a> </li> <li> <a href=\"javascript:void(0);\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" > <div class=\"index\"> 2 </div> </a> </li> <li> <a href=\"javascript:void(0);\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" > <div class=\"index\"> 3 </div> </a> </li> <li> <a href=\"javascript:void(0);\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" rel=\"external nofollow\" > <div class=\"index\"> 4 </div> </a> </li> </ul> </div> <script src=\"http://libs.baidu.com/jquery/2.0.0/jquery.min.js\"></script> <script type=\"text/javascript\"> $(function(){ $(\".index\").on(\"click\",function(){ var $target = $(this); console.log($(\".index\").index($target)); }); }); </script> </body> </html>
