data.forEach(function (object, index) {
console.debug(object.output);
//this consists of array object like below
//how to loop through these using higher order function so that I don't have to use for loop
[0]{"id": "453", "name":"keren"},
[1]{"id": "453", "name":"amy"},
[2]{"id": "453", "name":"samta"}
我得到的错误说,object.output不是一个函数。 我更喜欢高阶函数的原因是避免嵌套for循环获取数组的长度然后循环遍历主数组中的嵌套数组。
即使我使用传统的for循环,我也无法获得object.output的长度。
这是记录在内的内容:data.forEach(function (object, index) {....}
现在,我如何遍历每个输出对象?
根据Geeky回答编辑:
data.forEach(function (object, index) {
Object.keys(object).forEach(function (key){
if (typeof object[key] == 'object') {
console.debug(object[key]);
//how to iterate through each object here?
object[key].forEach(function(x){
console.debug(x);
});
}
});
});
答案 0 :(得分:1)
检查以下代码段
var arr=[ {"id": "453", "name":"keren"}
,{"id": "453", "name":"amy"}
,{"id": "453", "name":"samta"}
]
var object={"output":arr}
Traverse(object);
function Traverse(object){
Object.keys(object).forEach(function (key){
console.log(object[key]);
if(typeof(object[key])==="object")
Traverse(object[key]);
});
}

希望有所帮助
