Access object property in array of objects
提问by A Super Awesome
I have this set
我有这一套
var data = [
{"outlet_name":"Easy Lane Supermart","20130102_20130108":"0"},
{"outlet_name":"Eunilaine Foodmart Kalayaan","20130102_20130108":"0"},
{"outlet_name":"PUREGOLD PRICE CLUB, INC - VISAYAS","20130102_20130108":"0"}
];
$.each(data, function (i, item) {
$.each(item, function (k,v) {
$('#result').append(k,v);
});
});
How can I make it only view all the values of outlet_namewithout using the item.outlet_name?
我怎样才能让它只查看所有的值outlet_name而不使用 item.outlet_name？
回答by Strille
$.each(data, function (i, item) {
console.log(item.outlet_name);
});
Or without jQuery:
或者没有 jQuery：
for (var i=0;i<data.length;i+=1) {
console.log(data[i].outlet_name);
}
Ok, if you want to iterate over each object you can write:
好的，如果你想遍历每个对象，你可以写：
$.each(data, function (i, item) {
console.log("Values in object " + i + ":");
$.each(item, function(key, value) {
console.log(key + " = " + value);
});
});

{"outlet_name":"PUREGOLD PRICE CLUB, INC - VISAYAS","20130102_20130108":"0"}
];
for(i=0;i<data.length;i++){
for(var x in data[i]){
console.log(x + " => " + data[i][x]);
}

If anyone is needing to do this from a JSON string for example
例如，如果有人需要从 JSON 字符串执行此操作
var myJson = [{"Code":"slide_1.png","Description":"slide_1"},{"Code":"slide_2.png","Description":"slide_2"},{"Code":"slide_3.png","Description":"slide_3"}]
You can use
var newJsonArray = JSON.Parse(myJson)and you will get
Array[3]
0
:
Object
1
:
Object
2
:
Object
你可以使用
var newJsonArray = JSON.Parse(myJson)，你会得到 Array[3] 0 : Object 1 : Object 2 : Object
At which point you can access it by simply saying newJsonArray[i].Codeor whatever property inside the array you want to use. Hope this helps!
在这一点上，您可以通过简单地说出newJsonArray[i].Code或您想要使用的数组中的任何属性来访问它。希望这可以帮助！
