html里面 监听回车事件
监听回车，若回车按下，执行相应操作
document.onkeypress=kDown;
if (document.layers)
{
window.captureEvents(Event.KEYDOWN);
}
function kDown(e)
{
var key = 0 ;
if(window.event)
{
key = window.event.keyCode;
}
else if(e)
{
key = e.which ;
}
if(key==13)
{
checkfindPsw();//要执行的函数
return false;
}
}<!DOCTYPE html>

c 字符串分割
str为要分割的字符串
delimiter 为分割字符
分割到内容存放到splite_arry数组里
类似于js里的
var arr = new Array();
var tmp = "2420@1@you tel num?@1@453763leaq72";
arr = tmp.split("@");/*splite string, get tne answer to the use input(start)
