数组间的比较过滤/JS取出两个数组相同元素或者不同元素
取出两个数组相同元素,组成一个新的数组对象
let data = [ {name: "name一",isSelected: false,value: 111}, {name: "name二",isSelected: false,value: 222}, {name: "name三",isSelected: false,value: 333}, {name: "name四",isSelected: false,value: 444} ]; let arr1 = [ { isHas: true , id: 111, title: "no image11" },{ isHas: false , id: 222, title: "no image22" },{ isHas: true , id: 333, title: "no image33" }]; let newArr = []; let isExit; for (let i = 0; i < arr1.length; i++) { for (let j = 0; j < data.length; j++) { if(data[j].value === arr1[i].id){ isExit = true; } } isExit && newArr.push(arr1[i]) } console.log(newArr)
