JQuery框架中使用blockUI制作自定义的漂亮的网页提示框

一、介绍blockUI

它是Jquery框架的一个插件,专门用来做提示框、模态窗口的

具体的使用方法和demo里面都写得很清楚,我不再一一陈述

二、重写javascript中的alert,使得所有调用alert的地方都有统一的样式

这里我提供一个js文件
$.blockUI.defaults.overlayCSS.backgroundColor="#d5d5d5";
$.blockUI.defaults.pageMessageCSS.border="none";
//$.blockUI.defaults.pageMessageCSS.backgroundColor="#D6D6D6";
$.blockUI.defaults.pageMessageCSS.margin="-50px 0 0 -200px";
$.blockUI.defaults.pageMessageCSS.width="400px";
$.blockUI.defaults.overlayCSS.cursor='normal';
function Confirmer(title,message,callback,callback1,txt1,txt2)...{

if(!txt1)...{
txt1 = "确定";
}
if(!txt2)...{
txt2 = "取消";
}
var dhtml="";
dhtml+="<div class='DialogContainer'>";
dhtml+=" <div class='Title'>"+title+"</div>";
dhtml+=" <div class='Content'>"+message+"</div>"
dhtml+=" <div class='buttons'>";
dhtml+=" <input type='button' value='"+txt1+"' id='btn_Confirmer_OK'/>"
dhtml+=" <input type='button' value='"+txt2+"' id='btn_Confirmer_CANCEL'/>"
dhtml+=" </div>"
dhtml+="</div>";

$.blockUI(dhtml);
$("#btn_Confirmer_OK").click(function()...{

$.unblockUI();
setTimeout(function()...{
$(callback);
},500);
});

$("#btn_Confirmer_CANCEL").click(function()...{
$.unblockUI();
if(callback1)...{
$(callback1);
}
});
}

function Alert(message,callback)...{
var dhtml="";
dhtml+="<div class='DialogContainer'>";
dhtml+=" <div class='Title'>消息框</div>";
dhtml+=" <div class='Content'>"+message+"</div>"
dhtml+=" <div class='buttons'>";
dhtml+=" <input type='button' value='确定' id='btn_alert_Ok' />";
dhtml+=" </div>"
dhtml+="</div>";
$.extend($.blockUI.defaults.pageMessageCSS, ...{ border:'solid 1px #7199b1'});
$.blockUI(dhtml);
$("#btn_alert_Ok").focus();
$("#btn_alert_Ok").click(function()...{

$.unblockUI();
setTimeout(function()...{
eval(callback);
},500);
});
}


这里我故意把alert改为了大写的Alert,因为我觉得如果重写以前的alert方法,调试不太方便;

三、在页面调用的时候需要引用的资源文件
<link href="/css/DialogUI.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="/js/blockUI.js" ></script>
<script type="text/javascript" src="/js/commondialog.js" charset="gb2312"></script>
<script src="/js/jquery-1.2.1.js" type="text/javascript"></script>


四、分析css文件
div.blockUI{...}{
border:1px solid red;
background-color:#335577;
}

//整体的DIV层样式
.DialogContainer{...}{
width:400px;
height:200px;
cursor:default;
}

//提示框里面的样式
.DialogContainer .Title{...}{
background-color:#7199b1;
color:white;
font:caption;
text-align:left;
padding-top:3px;
padding-bottom:3px;
padding-left:5px;
}

//标题样式
.DialogContainer .Content{...}{
font-size:12px;
line-height:25px;
height:160px;
padding-top:20px;
padding-left:15px;
text-align:left;
}
//内容样式

.DialogContainer .buttons{...}{
text-align:right;
padding-right:20px;
padding-bottom:10px;
}

//按钮样式
.DialogContainer .buttons input{...}{
margin-left:20px;
text-align:center;
background-color: #ffffff;
border-right: #7199b1 2px solid;
padding-right: 8px;
border-top: #7499ae 1px solid;
padding-left: 8px;
font-size: 14px;
background-image: url(../images/anniu/out.gif);
border-left: #7499ae 1px solid;
cursor: hand;
color: #053152;
padding-top: 5px;
padding-bottom: 0px;
border-bottom: #7199b1 2px solid;
}
