我是靠谱客的博主坦率巨人，这篇文章主要介绍js脚本实现数据去重，现在分享给大家，希望可以做个参考。

项目要求如图所示：

代码：

复制代码代码如下:

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

    <script src="jquery.js"></script>

    <script type="text/javascript">

    $(function(){

        var divArea = $(".drop");

                $.each(divArea , function () {

                    var Dtxid = $(this).text();

                    var count = 0;

                    $.each(divArea , function () {

                            var Xtxid = $(this).text();

                            if (Dtxid == Xtxid) {

                            count = count + 1;

                            if (count >= 2) {

                                   $(this).remove();

                            }

                    }

                })

            })

    });

    </script>

</head>

<body>

    <div>原先数据</div>

    <div>

        <span>张三</span>

        <span>李四</span>

        <span>王五</span>

        <span>张三</span>

        <span>王五</span>

    </div>

    <br/>

    <div>数据去重</div>

    <div>

        <span class="drop">张三</span>

        <span class="drop">李四</span>

        <span class="drop">王五</span>
