<script type="text/javascript"> getJson('age'); function getJson(key){ var jsonObj={"name":"傅红雪","age":"24","profession":"刺客"}; //1.使用eval方法 var eValue=eval('jsonObj.'+key); alert
需求是将b根据a的值替换对象中的key值 let a = ["code","name","date","font"]; let b = [{1:2,2:3,3:4},{1:2,2:3,3:4},{1:2,2:3,3:4}]; //[{'code':2,'name':3,'date':4},{'code':2,'name':3,'date':4},{'code':2,'name':3,'date':4}]; let c = b.
一 .for in 循环 1.获取json中的键(key)与值(value): var data = {name:'张三',age:'20岁',sex:'男'}; for (var a in data) { console.log(a); /*属性名*/ console.log(data[a]); /*属性值*/ }; 2.获取数组中的值 var a = ['apple','banana','pear']; for(var i in a){ console.log(i); /*在数组中的位置*/
Js代码 <script type="text/javascript"> getJson('age'); function getJson(key){ var jsonObj={"name":"张三","age":"24","profession":"工程师"}; 遍历Json串获取其属性 for(var item in jsonObj){ if(item
