Extjs复习笔记(九)-- 加载等待

登陆时的加载状态:


<style type="text/css" media="all">
	#loading {
		position: absolute;
		left: 40%;
		top: 40%;
		padding: 2px;
		z-index: 20001;
		height: auto;
		color: #225588;
	}

	#loading .loading-indicator {
		background: greenyellow;
		color: #444;
		font: bold 13px tahoma, arial, helvetica;
		padding: 10px;
		margin: 0;
		height: auto;
	}

	#loading-msg {
		font: normal 10px arial, tahoma, sans-serif;
	}

    </style>

<body>
   <div id="loading">
		<div class="loading-indicator">
			<img src="../images/extanim33.gif" width="32" height="32"
				style="margin-right: 8px; float: left; vertical-align: top;" />
			    蓝杰-图书管理系统
			<br />
			<span id="loading-msg"><font color="red">提示:</font>加载中,请耐心等待...</span>
		</div>
	</div>
	<script type="text/javascript">document.getElementById('loading-msg').innerHTML = '<font color="red">提示:</font>加载中,请耐心等待...';</script>
………………(页面其它内容)
<script type="text/javascript">
	   Ext.get('loading').remove();
	   function showAbout(){
	   		Ext.Msg.alert("关于","<div><img src='../images/about.jpg'/></div><div style='float:left;width:400px;'><hr/><h2>开发者:凌艺宾<br/>学校:中南大学<br/>培训:蓝杰公司<h2></div>");
	   }
    </script>
</body>
</html>

?或者做得简单一点:

直接在button里面加上如下语句就行了

?

	        handler : function() {
	            if (loginPanel.form.isValid()) {
	                    loginPanel.form.submit( {
	                        url : 'login.do',
	                        success : function(from, action) {
	                          Ext.get('loginpanel').remove();
	                          window.location.href='pages_share/main.html';
	                        },
	                        failure : function(form, action) {
	                           Ext.MessageBox.show({
			                    	title:"登录失败",
			                    	msg:"登录失败!请认真检查您的姓名密码及身份。",
			                    	icon:Ext.MessageBox.ERROR,
			                    	buttons:{"ok":"确定"}
			                    });
	                        },
	                        waitMsg : '正在登录,请耐心等候...'
	                    });
