从字符串中获取第二个和第三个单词 [英] Get second and third words from string

问题描述

我在jQuery中有字符串:

I have strings in jQuery:

var string1 = 'Stack Exchange premium';
var string2 = 'Similar Questions'; //  only two
var string3 = 'Questions that may already have your answer';

我如何从第二个和第三个单词中得到答案?

How can i get from this second and third words?

var second1 = ???;
var third1 = ???;
var second2 = ???;
var third2 = ???;
var second3 = ???;
var third3 = ???;

推荐答案

首先，您没有在jQuery中"的字符串和变量.jQuery与此无关.

First, you don't have strings and variables "in jQuery". jQuery has nothing to do with this.

第二，更改您的数据结构，如下所示:

Second, change your data structure, like this:

var strings = [
    'Stack Exchange premium',
    'Similar Questions',
    'Questions that may already have your answer'
];

然后使用第二个和第三个单词创建一个新的数组.

Then create a new Array with the second and third words.

var result = strings.map(function(s) {
    return s.split(/\s+/).slice(1,3);
});

现在您可以像这样访问每个单词:

Now you can access each word like this:

console.log(result[1][0]);

这将为您提供第二个结果的第一个单词.

This will give you the first word of the second result.
