用id数组去对象数组寻找id对应的对象

var tabbar = [{id:'1',name:'张三'}，{id:'2',name:'李四'}，{id:'3',name:'小赵'}];
var ids=['1','2'];//id数组
 var selected_tab=[];//临时定义数组，用来存数据
 var selected = [];//最终结果
 ids.map(function (item) {
   selected_tab=tabbar.filter(function (obj) {
      return obj.id == item
   });
  selected.push(Object.assign({},...selected_tab))
})
console.log(selected); // 打印结果为[{id:'1',name:'张三'}，{id:'2',name:'李四'}]
