js去除数组中对象某个属性
适用场景:类似树状图的数组中对象的children属性,数组长度是否为0,若为0,则去除该节点,反之,保留改属性
通过递归方式实现,主要代码如下:
let arr = [ {id:1,lable:"父节点",children:[{id:11,lable:"子节点1"}]}, {id:2,lable:"父节点2",children:[{id:11,lable:"子节点1"},{id:11,lable:"子节点1-2",children:[{id:111,lable:"子节点1-2-1"}]}]}, ] let newArr = isChildrenFun(arr) function isChildrenFun(arr){ if (arr.length) { for (let i in arr) { if (arr[i].children.length) { isChildrenFun(arr[i].children) } else { delete arr[i].children; } } } return arr }
