js map 修改数据

Question

替换数据中所有front_name 改为 label（包括lab内的front_name）

  var kvArray = [
      {key: 1, value: 10, front_name:'出库', lab:[{id: 1, front_key: "chuku-list", front_name: "出库列表1"},{id: 2, front_key: "chuku-list", front_name: "出库列表2"}]},
      {key: 2, value: 20, front_name:'入库', lab:[{id: 1, front_key: "chuku-list", front_name: "入库列表1"},{id: 2, front_key: "chuku-list", front_name: "入库列表2"}]},
      {key: 3, value: 30, front_name:'存库', lab:[{id: 1, front_key: "chuku-list", front_name: "存库列表1"},{id: 2, front_key: "chuku-list", front_name: "存库列表2"}]}
  ]; 
  var reformattedArray = kvArray.map(function(obj) { 
       var rObj = {};
       rObj['label'] = obj.front_name;
       return rObj;
   });
   console.log( JSON.stringify(reformattedArray) )

没太理解你的提问，如果是指将front_name这个属性名改成label的话，试试下面这样。

var reformattedArray = kvArray.map(function(obj) { 
     obj.label = obj.front_name;
     delete obj.front_name;
     return obj;
 });
