定义弹出框div信息

<div tabindex="-1" role="dialog" aria-describedby="dialog-form" aria-labelledby="ui-id-1"
     style="position: absolute; height: auto; width: 350px; top: 0px; left: 581px; display: none; z-index: 101;">
    <div id="dialog-form" class="ui-dialog-content ui-widget-content"
         style="width: auto; min-height: 0px; max-height: none; height: 100px;">
        <p class="validateTips">请输入支付密码：p>
        <form>
            <fieldset>
                <input type="password" name="password" id="password" class="text ui-widget-content ui-corner-all">
                <input type="submit" tabindex="-1" style="position:absolute; top:-1000px">
            fieldset>
        form>
    div>
div>

后台部分代码

@ResponseBody
    @Transactional
    @RequestMapping("toOrdersOne")
    public String toOrdersOne(String payPwd, HttpSession session) {
    }
