<>前沿
这是笔者用来自己笔记用的。
<>一 ，给json中动态添加多个键值对
给数组中的每一个json对象动态添加n个键值对 let jsonArray = [ { name: "张三" }, { name: "李四" }, {
name: "王五" } ]; let indexCodeLists = [ { age: "12" }, { age: "16" } ]; for (let
rt= 0; rt < jsonArray .length; rt++) { for (let g = 0; g < indexCodeLists.length
; g++) { jsonArray [rt][`DatumName${g}`] = indexCodeLists[g].age; } } console.
log(jsonArray);---------------------------------> jsonArray = [ { name: "张三",
DatumName0:"12", DatumName1:"16", }, { name: "李四", DatumName0:"12", DatumName1:
"16", }, { name: "王五", DatumName0:"12", DatumName1:"16", } ];
<>二，获取json对象的key和value
let filterJson = { name:"张三"， age:"12", sex:"男" }; for (var key in filterJson)
{ console.log(key); //获取key值 console.log(json[key]); //获取对应的value值 }
