javascript - JavaScript通过json数组循环？(JavaScript loop through json array?)

Question

I am trying to loop through the following json array:(我试图遍历以下json数组：)

{ "id": "1", "msg": "hi", "tid": "2013-05-05 23:35", "fromWho": "[email protected]" }, { "id": "2", "msg": "there", "tid": "2013-05-05 23:45", "fromWho": "[email protected]" } And have tried the following(并尝试了以下) for (var key in data) { if (data.hasOwnProperty(key)) { console.log(data[key].id); } } But for some reason i am only getting the first part, id 1 values.(但是由于某种原因，我只得到第一部分，id 1值。) Any ideas?(有任何想法吗？)   ask by Alosyius translate from so

Answer 1

Your JSON should look like this:(您的JSON应该如下所示：)

var json = [{ "id" : "1", "msg" : "hi", "tid" : "2013-05-05 23:35", "fromWho": "[email protected]" }, { "id" : "2", "msg" : "there", "tid" : "2013-05-05 23:45", "fromWho": "[email protected]" }]; You can loop over the Array like this:(您可以像这样遍历数组：) for(var i = 0; i < json.length; i++) { var obj = json[i]; console.log(obj.id); } Or like this (suggested from Eric) be careful with IE support(或像这样（由Eric建议）应注意IE支持) json.forEach(function(obj) { console.log(obj.id); });
