JAVA实现scp功能,JavaScprit

JavaScprit---基础代码

var text = "Hello World";

document.write("

" + text.indexOf("Hello")  + "

document.write("

" + text.indexOf("World")  + "

document.write("

" + text.indexOf("world")  + "

document.write(text.match("Hello"));

document.write(text.match("World"));

document.write(text.match("Supan"));

document.write(text.replace(/Hello/, "Supans"));  //输出Supans World

document.write("
");

document.write(text);

document.write(Date());  //Sat Mar 01 2014 22:58:22 GMT+0800

var d=new Date();   //当前日期时间

document.write("从 1970/01/01 至今已有：" + d.getTime() + " 毫秒。");

d.setFullYear(1992,10,3);   //设置日期

document.write(d);

var d = new Date();

var weekday = new Array(7);

weekday[0]="星期日";

weekday[1]="星期一";

weekday[2]="星期二";

weekday[3]="星期三";

weekday[4]="星期四";

weekday[5]="星期五";

weekday[6]="星期六";

document.write("今天是：" + weekday[d.getDay()]);

数字始终代码：

function startTime(){

var today = new Date();

var h = today.getHours();

var m = today.getMinutes();

var s = today.getSeconds();

//add a zero in front of numbers < 10

m = checkTime(m);

s = checkTime(s);

document.getElementById("txt").innerHTML = h + ":" + m + ":" + s;

//setTimeout 方法用于在指定的毫秒数后调用函数或计算表达式。

setTimeout('startTime()',500);

}

//分钟，秒不足10的前面加上一个字符0

function checkTime(i){

if(i < 10){

i = "0" + i;

}

return i;

}

数组：

var mycars = new Array();

mycars[0] = "Saab";

mycars[1] = "Volvo";

mycars[2] = "bmw";

for(var i = 0; i < mycars.length; i++)

{

document.write(mycars[i] + "");

}

//数组的for循环，x是mycars的下标

for( x in mycars){

document.write(mycars[x] + "");

}
