使用方法：

1、引入css

2、引入HTML，你也可以将HTML转化为JS（http://www.css88.com/tool/html2js/），然后在页面中插入

对任意的input:text加入onclick = "shurufa_open(this) " 和 readonly="readonly" 如：

<input id="add_lianxiren" readonly="readonly" onclick="parent.shurufa_open(this)" type="text" value="" placeholder="请输入联系人" class="mui-input-clear" />
