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
}
