在<a>标签中添加弹出对话框代码如下，其中模态框部分一定只能放在<body>标签中且<a>标签中要有data-toggle="modal"(bootstrap的模态框插件)
<div class="pull-left">
<a href="#" class="btn btn-default btn-flat" data-toggle="modal" data- target="#pwdEditDialog">修改密码</a>
</div>
模态框代码
<div class="modal fade" id="pwdEditDialog" tabindex="-1" role="dialog"
aria-labelledby="myModalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title" >修改密码</h4>
</div>
<div class="modal-body">
<form class="form-horizontal" id="edit_pwd_form">
<input type="hidden" id="sid" name="sid" value="${session.sid}"/>
<div class="form-group">
<label for="password" class="col-sm-2 control-label">输入密码</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="password" placeholder="输入密码" name="password">
</div>
</div>
<div class="form-group">
<label for="checkpwd" class="col-sm-2 control-label">确认密码</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="checkpwd" placeholder="确认密码" name="checkpwd">
</div>
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">关闭</button>
<button type="button" class="btn btn-primary" onclick="updatePwd()">保存修改</button>
