小黑小波比.实现button关闭窗体

<div  id="myModal" tabindex="-1" style="position:absolute;zIndex:9999;display:none;width:200px;height:220px;top:100px;left:100px;">
							<div class="modal-dialog">
								<div class="modal-content">
											<div class="modal-header">
												<button type="button" class="close" 
													data-dismiss="modal" aria-hidden="true" on="btnClose">
													×
												</button>
												<h4 class="modal-title" id="myModalLabel">
													提示
												</h4>
											</div>
											<div class="modal-body">
												验证成功!
											</div>
											<div class="modal-footer">
												<button type="button" class="btn btn-primary" 
												data-dismiss="modal" on="btnClose">确定
												</button>
											</div>
								</div>
							</div>
						</div>

在确定和x按钮设定事件为on="btnClose"

btnClose:function(sender,arg){
           _('#myModal').hide();
        },

在事件中插入这事件代码.#myModal代表id为myModal,hide()代表隐藏 show()代表显示
