ASP一些常用的辅助代码(网络收藏)

var copytoclip=1

function HighlightAll(theField) {
var tempval=eval("document."+theField)
tempval.focus()
tempval.select()
if (document.all&&copytoclip==1){
therange=tempval.createTextRange()
therange.execCommand("Copy")
window.status="Contents highlighted and copied to clipboard!"
setTimeout("window.status=''''",1800)
}
}
//-->
</SCRIPT>

屏蔽JAVASCRIPT错误
<script language="JavaScript">
<!--
function killErrors(){
return true;
}
window.onerror = killErrors;
-->
</script>

关闭子窗口时刷新父窗口
<script language="JavaScript">
<!--
self.opener.location.reload();
window.close()
-->
</script>

背景色变换
<form>
<p><input TYPE="button" VALUE="背景色变换" onClick="BgButton()"></p>
</form>
<script>function BgButton(){
if (document.bgColor==''#00ffff'')
{document.bgColor=''#ffffff'';}
else{document.bgColor=''#00ffff'';}
}
</script>

检查一段字符串是否全由数字组成
<script language="Javascript"><!--
function checkNum(str){return str.match(//D/)==null}
alert(checkNum("1232142141"))
alert(checkNum("123214214a1"))
// --></script>

判断是否是字符
if (/[^/x00-/xff]/g.test(s)) alert("含有汉字");

点击刷新代码:
<form>
<p><input TYPE="button" VALUE="刷新按钮一" ONCLICK="ReloadButton()"></p>
</form>
<script language="JavaScript"><!--
function ReloadButton(){location.href="allbutton.htm";}
// --></script>

让层不被控件复盖代码:
<div z-Index:2><object xxx></object></div> ＃ 前面
<div z-Index:1><object xxx></object></div> ＃ 后面
<div id="Layer2" style="position:absolute; top:40;width:400px; height:95px;z-index:2"><table height=100% width=100% bgcolor="#ff0000"><tr><td height=100% width=100%></td></tr></table><iframe width=0 height=0></iframe></div>
<div id="Layer1" style="position:absolute; top:50;width:200px; height:115px;z-index:1"><iframe height=100% width=100%></iframe></div>

让层的相对定位
<div id="Layer1" style="position:relative; left:0px; top:0px; width:0px; height:0px;z-index:1">
<div id="Layer2" style="position:absolute; left:500px; top:0px; width:220px; height:220px; z-index:1">
内容
</div></div>
