获取匹配词后的下一个单词在Javascript中

Question

想要从字符串“申请2项保险”后得到第一个单词。

var Number = 2; 
var text = "Apply for 2 insurances or more"; 

在这种情况下，我想找到Number后的字符串，所以我的预期结果为：“保险”

Answer 1

呦ü可以简单地使用正则表达式号之后拿到的第一个字，就像这样......

var number = 2; 
 
var text = "Apply for 2 insurances test"; 
 
var result = text.match(new RegExp(number + '\\s(\\w+)'))[1]; 
 

 
console.log(result);

Answer 2

与findIndex一个解决方案，该号码后得到只有两个字：

var number = 2; 
 
var text = "Apply for 2 insurances or more"; 
 
var words = text.split(' '); 
 

 
var numberIndex = words.findIndex((word) => word == number); 
 
var nextWord = words[numberIndex + 1]; 
 

 
console.log(nextWord);

Answer 3

var number = 2; 
 
var sentence = "Apply for 2 insurances or more"; 
 

 
var othertext = sentence.substring(sentence.indexOf(number) + 1); 
 
console.log(othertext.split(' ')[1]); 
 

 
//With two split 
 
console.log(sentence.split(number)[1].split(' ')[1]);
