cursor: 'wait'
}
});
});
})
</script>
2.弹出一个隐藏的弹出框
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8" />
<title>blockUI（弹出层）</title>
<style type="text/css">
#demo {
width:100px;
height:24px;
text-align:center;
}
#displayBox{
display:none;
}
</style>
</head>
<body>
<button id="demo">点击弹出</button>
<div id="displayBox">
这里是弹出层显示的内容！！！<br /><br /><br /><a href="javascript:void(0);" onclick="$.unblockUI();return false;" title="点击关闭">点击关闭</a>
</div>
</body>
</html>
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="jquery.blockUI.js"></script>
<script type="text/javascript">
$(function(){
$('#demo').click(function(){
$.blockUI({
message: $('#displayBox'),
css: {
width: '500px',
height: '100px',
backgroundColor: '#eee',
border: '1px solid red',
color: 'green',
textAlign: 'center',
cursor: 'default'
}
});
});
})
</script>
3.直接弹图片
<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>
