如何检查字符串是否包含JavaScript中的字符串数组中的子字符串

Question

我仍在学习JavaScript，但似乎找不到找到字符串是否包含子字符串的方法。

基本上，我有一些个人的标题，我想看看标题中是否包含诸如“ President”或“ Sr”之类的字符串，这是我到目前为止所能使用的，但似乎无法正常工作。

var title = "President of Sales";
var arrayOfTitles = ["President","Chief","VP","SVP","Director","Manager","Mrg","Sr","Senior","Executive Assistant","Principle Architect","GM","Technical Advisor"];

var re = new RegExp(arrayOfTitles.join("|"),"i");

for(i = 0; i < arrayOfTitles.length; i++){
        if ( re.test(gr.title)){
            return; 
                }
     }

但是，此代码不适用于“ Jr VP”或“ President of Sales”之类的String。 有没有办法建立这些字符串的正则表达式数组？

任何帮助将非常感谢

Answer 1

您不需要运行循环

 var title = "President of Sales"; var arrayOfTitles = ["President","Chief","VP","SVP","Director","Manager","Mrg","Sr","Senior","Executive Assistant","Principle Architect","GM","Technical Advisor"]; var regex = new RegExp(arrayOfTitles.join("|"), "i"); //The regex will return true if found in the array if ( regex.test(title) ){ console.log("has"); } 

Answer 2

简单的东西怎么样：

 var title = "President of Sales"; var arrayOfTitles = ["President","Chief","VP","SVP","Director","Manager","Mrg","Sr","Senior","Executive Assistant","Principle Architect","GM","Technical Advisor"]; var matches = (function() { for(var i=0; i < arrayOfTitles.length; i++) { if(title.indexOf(arrayOfTitles[i]) > -1) { return true; } } return false; }()); 

Answer 3

您也可以使用include（）函数代替indexOf（）。

     var title = "President of Sales";
       var arrayOfTitles = ["President","Chief","VP","SVP","Director","Manager","Mrg","Sr","Senior","Executive Assistant","Principle Architect","GM","Technical Advisor"];
       var matches = (function() {
         for(var i=0; i < arrayOfTitles.length; i++) {
               if(title.includes(arrayOfTitles[i])) { return true; }
         }
         return false;
       }());
