递归遍历JS的对象的每个属性

递归遍历JS的对象的每个属性

1）使用constructor

<span style="font-size:14px;">var model = {
fullName: {
firstName: 'paradise',
lastName: 'fang'
},
age: 25,
sex: 'female',
array : [1,2,3]
};
buildModel(model);

function buildModel(model) {
for (var i in model) {
if (model[i] != null) {
if (model[i].constructor == Object) {
buildModel(model[i]);
} else {
console.log(i + "\t" + model[i]);
}
}
}
}</span>

2）使用typeof

<span style="font-size:14px;">var model = {
fullName: {
firstName: 'paradise',
lastName: 'fang'
},
age: 25,
sex: 'female',
array : [1,2,3]
};
buildModel(model);

function buildModel(model) {
for (var i in model) {
if (model[i] != null) {
if (typeof model[i] == "object") {
buildModel(model[i]);
} else {
console.log(i + "\t" + model[i]);
}
}
}
}</span>
