有一个这样的数组,我不知道怎么递归遍历返回出成为这样的数组形式
[{
text:‘北京市‘,
value:‘北京市‘,
children:[
{
text:‘东城区‘,
value:‘东城区‘
}
]
},{
text:‘北京市‘,
value:‘北京市‘,
children:[
{
text:‘东城区‘,
value:‘东城区‘
},
{
text:‘西城区‘,
value:‘西城区‘
}
]
}]
?请问一下怎么写这个递归的函数?
var newarr = [];
for(var i=0;i<arr.length;i++){
newarr[i] = {
text : arr[i].name,
value : arr[i].name,
childern : [{
text : arr[i].regions[0].name,
value : arr[i].regions[0].name
}]
};
}
console.log(newarr);
整理一下:
function abc(arr) {
var arr1 = [];
for(var i = 0, l = arr.length; i < l; i++) {
arr1[i] = {
text: arr[i].name,
value: arr[i].name,
children: [{
text: arr[i].regions[0].name,
value: arr[i].regions[0].name
}]
}
}
return arr1;
}
var a = abc(arr);
console.log(a)
这是我在:https://segmentfault.com/q/1010000008641909?_ea=1702980上看到的一个问题
