在线等！数组循环去掉不同的元素，求指教？怎么回事哈啊？

Question

vara1=[{path:'home'},{path:'index'}]vara2=[{path:'home'},{path:'index'},{path:'delpage'}]两个数组循环，删除不同的对象元素期望a2=[{path:'home'},{path:'index'}]

Answer 1

let leftData = [1,2,3,4,5]  //原数组

let targetKeys = [3,5]  //要删除的元素

let rightData = [6,7]   //最终需要的数组

let leg = this.leftData.length

for (let i = leg - 1; i >= 0; i--) {

    for (let j = 0; j < targetKeys.length; j++) {

        if (leftData[i]) {

            if (leftData[i] == targetKeys[j]) {

                rightData.push(leftData[i])

                leftData.splice(i, 1)

                continue; //结束当前本轮循环，开始新的一轮循环

            }

        }

    }

}
