我想检索数组中包含关键字卧室"的所有元素.我怎样才能达到这样的结果?

我尝试了不同的方法，但都没有得到想要的结果.我应该如何进行?

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

推荐答案

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 (仅在现代浏览器中):

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

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