全选

全选

function checkAll(str)
{
var a = document.getElementsByName(str);
var n = a.length;
for (var i=0; ia[i].checked = window.event.srcElement.checked;
}
function checkItem(str)
{
var e = window.event.srcElement;
var all = eval("document.hrong."+ str);
if (e.checked)
{
var a = document.getElementsByName(e.name);
all.checked = true;
for (var i=0; i{
if (!a[i].checked){ all.checked = false; break;}
}
}
else all.checked = false;
}

3.8 文件上传过程中判断文件类型

-------------------------------------------------------------------------------------
１．身份证严格验证：

２．验证ＩＰ地址

function isip(s){
var check=function(v){try{return (v<=255 && v>=0)}catch(x){return false}};
var re=s.split(".")
return (re.length==4)?(check(re[0]) && check(re[1]) && check(re[2]) && check(re[3])):false
}

var s="202.197.78.129";
alert(isip(s))

３．加sp1后还能用的无边框窗口！！
