javascript - 使用javascript或jquery使用数组中的多个值过滤数组对象

Question

行用户数组看起来像。

var users = [{name: 'John',address: 'USA',year:2010 },{name: 'John',address: 'USA',year:2011 },{name: 'John',address: 'USA',year:2012 },{name: 'John',address: 'USA',year:2013 },{name: 'John',address: 'USA',year:2014}];

过滤器数组是，

var filter_year = ['2010','2011','2012'];

我如何获得使用 filter_year 中的年份过滤的结果数组，我需要获得类似的结果数组。

var users = [{name: 'John',address: 'USA',year:2010 },{name: 'John',address: 'USA',year:2011 },{name: 'John',address: 'USA',year:2012 }];

Answer 1

您可以使用以下代码获取给定年份的所有用户。

var filter_year = ['2010','2011','2012'],
    users = [{name: 'John',address: 'USA',year:2010 },{name: 'John',address: 'USA',year:2011 },{name: 'John',address: 'USA',year:2012 },{name: 'John',address: 'USA',year:2013 },{name: 'John',address: 'USA',year:2014}],
    filteredUsers = []
    allYears = filter_year.join("|");
    
    for(var user in users) { 
    	if(allYears.indexOf(users[user].year) !== -1) {
      		filteredUsers.push(users[user]);
       }
    }
    
    console.log(filteredUsers);
