跟我做背景变暗,弹出提示层的功能,而且增加了对Select对象的支持
其实很简单,我也是学习别人的代码学习来的,
注意:密码是123

插入一个代码吧,方便你们用;)没办法,不能上传文件,还是贴代码吧;(
方法二 popup的方式
<script language="JavaScript">...
<!--
var oPopup=window.createPopup();
var oPopBody=oPopup.document.body;
var colorArr=["#F7F7F7","#E7E7E7","#D7D7D7","#D4D4D4","#BCBCBC","#ACACAC"];
var i=0;
var iMaxLength=6;
var timer=null;
function showPopup()...{
var oBody=document.body;
oPopBody.attachEvent("oncontextmenu",cancelEvent);
oPopBody.bgColor="#FFFFFF";
var strHTML=""
strHTML+='<center><div align="center" style="border:solid 2px #00FFFF;valign:middle; width:400; height:200">请您选中要操作的信件!<input type="button" value="确定" onclick="parent.hidePopup()"></div></center>';
oPopBody.innerHTML=strHTML;
oPopup.show(0,0,oBody.clientWidth,oBody.clientHeight,document.body);
chgBgcolor();
}
function chgBgcolor()...{
if(i<iMaxLength)...{
oPopBody.bgColor=colorArr[i++];
timer=setTimeout(chgBgcolor,100);
}
else...{
clearTimeout(timer);
i=0;
}
}
function cancelEvent()...{
return false;
}
function hidePopup()...{
oPopup.hide();
}
//-->
</script>
<input type="button" onclick="showPopup()" value="操作有误">
再加一个方法,带渐变效果的
<script language="JavaScript">...
<!--
var oPopup=window.createPopup();
var oPopBody=oPopup.document.body;
var colorArr=["#F7F7F7","#E7E7E7","#D7D7D7","#D4D4D4","#BCBCBC","#ACACAC"];
var i=0;
var iMaxLength=6;
var timer=null;
function showPopup()...{
var oBody=document.body;
oPopBody.attachEvent("oncontextmenu",cancelEvent);
oPopBody.bgColor="#FFFFFF";
var strHTML=""
strHTML+='<center><div align="center" style="border:solid 2px #00FFFF;valign:middle; width:400; height:200">请您选中要操作的信件!<input type="button" value="确定" onclick="parent.hidePopup()"></div></center>';
oPopBody.innerHTML=strHTML;
oPopup.show(0,0,oBody.clientWidth,oBody.clientHeight,document.body);
chgBgcolor();
}
function chgBgcolor()...{
if(i<iMaxLength)...{
oPopBody.bgColor=colorArr[i++];
timer=setTimeout(chgBgcolor,100);
}
else...{
clearTimeout(timer);
i=0;
}
}
function cancelEvent()...{
return false;
}
function hidePopup()...{
oPopup.hide();
}
