	<div id="myModal" class="modal hide" tabindex="-1" role="dialog"
		aria-labelledby="myModalLabel" aria-hidden="true">
		<div class="modal-header">
			<button type="button" class="close" data-dismiss="modal"
				aria-hidden="true">×</button>
			<h3 id="myModalLabel">查询用户</h3>
		</div>
		<div class="modal-body">
			<input type="text" id="moduleUserName" placeholder="用户名"> 
			<input type="text" id="moduleUserName" placeholder="用户编号"> 
			<button class="btn btn-primary">查询</button>
		</div>
		<div class="modal-footer">
			<button class="btn" data-dismiss="modal" aria-hidden="true">关闭</button>
			<button class="btn btn-primary" data-dismiss="modal" id="modalOk">确定</button>
		</div>
	</div>

用户名input输入框 点击以后会弹出模态窗口

<script type="text/javascript">
		$(function() {
<span style="white-space:pre">			</span>$('#myModal').on('hide.bs.modal', function() {
                // 执行一些动作...
              });
});
<span style="white-space:pre">	</span>function getUserInfo() {
<span style="white-space:pre">		</span>$("#myModal").modal({
                         backdrop: 'static',
<span style="white-space:pre">	</span>              show:true
            });
     }
	
</script>

backdrop: 'static' 属性保证modal窗口点击空白处不会自动关闭
