基于JQuery 的消息提示框效果代码

提示框效果

一下是封装到 Jquery.L.Message.js 中的JS文件内容

var returnurl = ''; 
var messagebox_timer; 
$.fn.messagebox = function (message, url, type, delay) { 
clearTimeout(messagebox_timer); 
$("#msgprint").remove(); 
var m_body = $(this); 
delay = (typeof delay == "undefined" ? 5000 : delay); 
returnurl = url; 
var box_style = 'position:absolute;display:none;z-index:1000;padding:10px 30px 10px 40px;'; 
switch (type) { 
case 1: box_style += 'border:1px solid Green;color:#090;background:url(../Icons/ok.png) 10px 10px no-repeat #F1FEF2;'; break; 
case 0: box_style += 'border:1px solid Red;color:#EE1010;background:url(../Icons/error.png) 10px 10px no-repeat #FDF8E8;'; break; 
default: box_style += 'border:1px solid Orange;color:Orange;background:url(../Icons/warning.png) 10px 10px no-repeat #FEFDE9;'; break 
} 
var str = "<div id="msgprint" style="" + box_style + "">" + message + "</div>"; m_body.append(str); 
var dom_obj = document.getElementById("msgprint"); 
var ext_width = $("#msgprint").width(); 
dom_obj.style.top = (document.documentElement.scrollTop + (document.documentElement.clientHeight - dom_obj.offsetHeight - $("#msgprint").height()) / 2) + "px"; 
dom_obj.style.left = (document.documentElement.scrollLeft + (document.documentElement.clientWidth - dom_obj.offsetWidth - $("#msgprint").width()) / 2) + "px"; 
$("#msgprint").fadeIn(1000, function () { messagebox_timer = setTimeout(messagebox_out, delay) }); 
}; 
function messagebox_out() { 
if (returnurl == undefined || returnurl == '') { $("#msgprint").fadeOut(1000) } 
if (returnurl == "back") { this.history.back(-1) } else if (returnurl != "" && returnurl != undefined) { this.location.href = returnurl } 
}

　　引用的js文件：

<script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"></script> 
<script src="Scripts/Jquery.L.Message.js" type="text/javascript"></script>

　　调用代码

<body> 
    <div id="hello" style="height: 350px;"> 
    <ul>
    <li><a href="javascript:$('#hello').messagebox('成功提示<br/>成功提示', 'http://localhost:5083/', 1, 20000);">成功，20秒后跳转</a></li> 
    <li> <a href="javascript:$('#hello').messagebox('错误提示<br/>错误提示', '', 0, 1000);">失败，1秒消失</a></li> 
    <li> <a href="javascript:$('body').messagebox('这是警告<br/>这是警告', 'back', 2);">警告，默认时间5秒后后退</a></li>
    </ul>
    </div>
</body>
