单个json对象
var data = {id:"1001",name:"null",age:"10",sex:"null",phone:"null"}
遍历对象判断是null并且设置为想要的值
for(attr in data){ //在遍历对象判断是null并且设置为想要的值
if(data[attr]==="null")data[attr]='未记录'
}
console.log(data)
输出结果
{id:"1001",name:"未记录",age:"10",sex:"未记录",phone:"未记录"}
请求接口获取到一个json字符串
var data=[
{id:"1001",name:"null",age:"10",sex:"null",phone:"null"},
{id:"1002",name:"null",age:"10",sex:"null",phone:"null"},
{id:"1003",name:"null",age:"10",sex:"null",phone:"null"},
]
遍历对象两次，第二次判断是null并且设置为想要的值
for(attr in data){
var data2 = data[attr] //第一次遍历拆成单个json，
for(attr in data2){ //在遍历对象判断是null并且设置为想要的值
if(data2[attr]==="null")data2[attr]='未记录'
}
}
console.log(data2)
输出结果
{id:"1001",name:"未记录",age:"10",sex:"未记录",phone:"未记录"}
