A数组:
var aa = [ {name:‘Anne‘, age: 23, gender:‘female‘}, {name:‘Leila‘, age: 16, gender:‘female‘}, {name:‘Jay‘, age: 19, gender:‘male‘}, {name:‘Mark‘, age: 40, gender:‘male‘} ]
一、筛选出Jay的资料: 用filter方法,判断name是否为目标名字即可
console.log(aa.filter(item=>item.name===‘Jay‘)); //[{…}] //0: {name: "Jay", age: 19, gender: "male"} //length: 1 //__proto__: Array(0)
二、筛选出Jay、Mark的资料:用for循环遍历目标数组,然后用find方法找到后push到结果数组里
let bb=[‘Jay‘,‘Mark‘] let result = [] for(let i = 0; i < bb.length; i++) { result.push(aa.find(item => item.name = bb[i])) } //输出为 [{name:‘Anne‘, age: 23, gender:‘female‘},{name:‘Jay‘, age: 19, gender:‘male‘}]
三、筛选出Jay或者23岁的资料:用filter方法,判断条件之间是或的关系。
aa.filter(item => item.name == ‘Jay‘ || item.age == 23)
