Question

asp如何让文本框输入的类型只能为数值?

var popUpWin=0;
function showModWin(URLStr,width, height, winname,left, top)
{
var left = (left==''||left==null)?(screen.width/2) - width/2:left;
var top = (top==''||top==null)?(screen.height/2) - height/2:top;

if(popUpWin)
{
if(!popUpWin.closed) popUpWin.close();
}
var winnames = (winname=='')?'popUpWin':winname;

popUpWin = window.showModalDialog(URLStr,
"","help:0;resizable:0;status=0;scrollbars=0;dialogWidth:"+width+"px;dialogHeight:"+height+"px;center=true");

}

还有这个谁可以帮忙解释下

用JS判断

for(i=96;i<=105;i++)
if(window.server.key<>i){alert("请输入数字！")}
requrn true
next

不知道写正确没 呵呵
