JavaScript循环遍历JSON数组? [英] JavaScript loop through JSON array?
本文介绍了JavaScript循环遍历JSON数组?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在尝试遍历以下 json 数组:
I am trying to loop through the following json array:
{
"id": "1",
"msg": "hi",
"tid": "2013-05-05 23:35",
"fromWho": "hello1@email.se"
}, {
"id": "2",
"msg": "there",
"tid": "2013-05-05 23:45",
"fromWho": "hello2@email.se"
}
并尝试了以下
for (var key in data) {
if (data.hasOwnProperty(key)) {
console.log(data[key].id);
}
}
但由于某种原因,我只得到第一部分,id 1 值.
But for some reason I'm only getting the first part, id 1 values.
有什么想法吗?
推荐答案
您的 JSON 应该如下所示:
Your JSON should look like this:
var json = [{
"id" : "1",
"msg" : "hi",
"tid" : "2013-05-05 23:35",
"fromWho": "hello1@email.se"
},
{
"id" : "2",
"msg" : "there",
"tid" : "2013-05-05 23:45",
"fromWho": "hello2@email.se"
}];
你可以像这样循环数组:
You can loop over the Array like this:
for(var i = 0; i < json.length; i++) {
var obj = json[i];
console.log(obj.id);
}
或者像这样(由 Eric 建议)小心 IE 支持
Or like this (suggested from Eric) be careful with IE support
json.forEach(function(obj) { console.log(obj.id); });
