脚本永不出错
<SCRIPT LANGUAGE="JavaScript">
<!-- Hide
function killErrors() {
return true;
}
window.onerror = killErrors;
// -->
</SCRIPT>
选择了哪一个Radio
<HTML><script language="vbscript">
function checkme()
for each ob in radio1
if ob.checked then window.alert ob.value
next
end function
</script><BODY>
<INPUT name="radio1" type="radio" value="style" checked>Style
<INPUT name="radio1" type="radio" value="barcode">Barcode
<INPUT type="button" value="check" onclick="checkme()">
</BODY></HTML>
日期减去天数等于第二个日期
<script language=JavaScript>
function cc(dd,dadd)
{
//可以加上错误处理
var a = new Date(dd)
a = a.valueOf()
a = a - dadd * 24 * 60 * 60 * 1000
a = new Date(a)
alert(a.getFullYear() + "年" + (a.getMonth() + 1) + "月" + a.getDate() + "日")
}
cc("12/23/2002",2)
</script>
TEXTAREA自适应文字行数的多少
<textarea rows=1 name=s1 cols=27 onpropertychange="this.style.posHeight=this.scrollHeight">
</textarea>
怎么判断是否是字符
if (/[^/x00-/xff]/g.test(s)) alert("含有汉字");
else alert("全是字符");
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>
在打开的子窗口刷新父窗口的代码里如何写？
window.opener.location.reload()
让弹出窗口总是在最上面:
<body onblur="this.focus();">
屏蔽功能键Shift,Alt,Ctrl
<script>
function look(){
if(event.shiftKey)
alert("禁止按Shift键!"); //可以换成ALT CTRL
}
document.onkeydown=look;
</script>
光标是停在文本框文字的最后
<script language="JavaScript">
function cc()
{
var e = event.srcElement;
var r =e.createTextRange();
r.moveStart("character",e.value.length);
r.collapse(true);
r.select();
}
</script>
<input type=text name=text1 value="123" onfocus="cc()">
