显示遮罩层的插件：blockUI

1、自定义消息和样式：

jQuery(document).ready(function(){
	//jQuery(document).ajaxStart(jQuery.blockUI).ajaxStop(jQuery.unblockUI);
	jQuery(document).ajaxStop(jQuery.unblockUI);
});

function _click(){
	jQuery.blockUI({
		message: "<font><br>正在处理，请稍候...<br><br></font>",
		css: {
			width: "250",
			backgroundColor: "#7EC0EE",
			border: "2px solid #104E8B"
		}
	});
	setTimeout(function(){jQuery.get("index.html");}, 3000);
}

 

 

2、对div区域应用遮罩效果

function _click(){
	jQuery("#div1").block({
		message: "<font>正在处理，请稍候...</font>",
		css: {
			width: "200",
			backgroundColor: "#7EC0EE",
			border: "2px solid #104E8B"
		}
	});

	setTimeout(function(){jQuery.get("index.html", function(){jQuery("#div1").unblock();});}, 3000);
}

 

3、自定义对话框

<script language="javascript">
	jQuery(document).ready(function(){
		jQuery("#btnClick").click(function(){
			jQuery.blockUI({
				message: jQuery("#question"),
				css: {
					width: "300",
					textAlign: "left",
					padding: "8px",
					backgroundColor: "#BDB76B",
					border: "3px solid #548B54"
				}
			});
		});

		jQuery("#yes").click(function(){
			jQuery.blockUI({
				message: "<br><font>请稍候...<br><br></font>",
				css: {
					width: "300",
					backgroundColor: "#7EC0EE",
					border: "2px solid #104E8B"
				}
			});
			
			setTimeout(function(){jQuery.get("index.html", function(){jQuery.unblockUI();});}, 3000); 
		});

		jQuery("#no").click(function(){
			jQuery.unblockUI();
		});
	});
</script>

<input id=btnClick type=button value=click>

<div id="question" style="display:none; cursor:default;"> 
	<table border=0 width="100%">
		<tr><td style="font-size:13px;">确定要提交吗？<br><br></td></tr>
		<tr>
			<td align="center">
				<input type="button" id="yes" value=" 是 " />&nbsp;&nbsp;
				<input type="button" id="no" value=" 否 " /> 
			</td>
		</tr>
	</table>
</div>

 

4、遮罩层显示图片，并定位在右上角

<script language="javascript">
	jQuery(document).ready(function(){
		jQuery.blockUI.defaults.message = "<br><font>请稍候...<br><br></font>";
		jQuery.blockUI.defaults.css.width = "300";
		jQuery.blockUI.defaults.css.backgroundColor = "#FFFFFF"; //#7EC0EE
		jQuery.blockUI.defaults.css.border = "0px solid #104E8B";

		jQuery.blockUI.defaults.overlayCSS.backgroundColor = "#FFF68F"; //遮罩的背景色
		
		//遮罩层显示图片，并定位在右上角
		jQuery("#btnClick").click(function(){
			jQuery.blockUI({
				message: jQuery("#question"),
				centerY: 0,
				css: {
					width: jQuery("#img1").width(),
					height: jQuery("#img1").height(),
					left: "",
					right: "10",
					top: "10"
				},
				fadeIn: 700, //淡入的时间长度
				fadeOut: 700, //淡出的时间长度
				showOverlay: false, //不显示遮罩背景色
				timeout: 2000 //自动退出遮罩
			});
			
			/*
			setTimeout(function() { 
				jQuery.unblockUI({ 
					onUnblock: function(){ alert('退出遮罩后触发该事件！'); } 
				}); 
			}, 3000); 

			jQuery('.blockOverlay').attr('title', '单击退出遮罩').click(jQuery.unblockUI); 
			*/
		});
	});
</script>

<input id=btnClick type=button value=click>

<div id="question" style="display:none; cursor:default;"> 
	<img id="img1" src="111.jpg">
</div>
