Filter strings in Array based on content

问题:

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

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

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

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

回答1:

String.prototype.indexOf:

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

Regexp:

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

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

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

回答2:

var bedrooms = myArray.filter(name => name.includes('bedroom'))

Improved Microfed's answer to this

var textToSearch = 'bedroom';
var filteredArray = myArray.filter((str)=>{
  return str.toLowerCase().indexOf(textToSearch.toLowerCase()) >= 0; 
});
