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。
