在阵列过滤字符串基于内容 [英] Filter strings in Array based on content

问题描述

我遇到了一个问题，我有一个字符串在JS类似数组：

I am running into an issue, I have a similar array of Strings in JS:

var myArray = ["bedroomone", "bedroomonetwo", "bathroom"];

和我想检索包含关键字卧室的阵列中的所有元素。我怎样才能达到这样的结果？

And I would like to retrieve all the elements in the array that contains the keyword 'bedroom'. How can I achieve such result ?

我尝试以不同的方式没有得到所期望的结果。我该如何操作？

I tried in different ways without getting the desired result. How should I proceed ?

推荐答案

的 String.prototype.indexOf ：

var PATTERN = 'bedroom',
    filtered = myArray.filter(function (str) { return str.indexOf(PATTERN) === -1; });

正则表达式：

var PATTERN = /bedroom/,
    filtered = myArray.filter(function (str) { return PATTERN.test(str); });

String.prototype.includes （只有在MODERM浏览器）：

String.prototype.includes (only in moderm browsers):

var PATTERN = 'bedroom',
    filtered = myArray.filter(function (str) { return str.includes(PATTERN); });
