javascript实现随机读取数组的方法

本文实例讲述了javascript实现随机读取数组的方法。分享给大家供大家参考。具体如下：

function write_quote() {

var quotes = [

'no animals were harmed while making this page',

'made in ulm',

'this page was handmade',

'Get <a href="http://www.mozilla.org/products/firefox/">FireFox</a> :-)'

];

var r = Math.round(Math.random() * (quotes.length-1));

// write the quote

document.write(quotes[r]);

// or replace an HTML element:

// document.getElementById("quote").innerHTML = quotes[r];

}

希望本文所述对大家的javascript程序设计有所帮助。
