Random Text From jQuery Array

javascriptjquery

提问by conbask

I am trying to make an array of strings and then pluck a random string and place it in a div with class "quote". Below is my current code.

我正在尝试创建一个字符串数组,然后随机抽取一个字符串并将其放置在一个带有“quote”类的 div 中。下面是我目前的代码。

$(document).ready(function() {

    var quotes = new Array("foo", "bar", "baz", "chuck");
    var randno = Math.floor ( Math.random() * quotes.length );
    $('.quote').add(quotes[randno]);

});

What am I doing incorrectly?

我做错了什么?

Thanks

谢谢

    randno = quotes[Math.floor( Math.random() * quotes.length )];
    $('.quote').text( randno );
});
