Json values in jQuery foreach loop
提问by Simpanoz
I'm getting the following JSON response from the server:
我从服务器收到以下 JSON 响应：
[{"id":"1","pid":"0","type":"Individual","code":"i","status":"1"},
{"id":"2","pid":"0","type":"Group","code":"g","status":"1"},
{"id":"15","pid":"0","type":"asdasd","code":"asd","status":"1"},
{"id":"16","pid":"0","type":"asdas","code":"asd","status":"1"},
{"id":"17","pid":"0","type":"my check","code":"mt","status":"1"}]
How can I make jQuery foreach loop and get only values of idand type.

var json = '[{"id":"1","pid":"0","type":"Individual","code":"i","status":"1"},{"id":"2","pid":"0","type":"Group","code":"g","status":"1"},{"id":"15","pid":"0","type":"asdasd","code":"asd","status":"1"},{"id":"16","pid":"0","type":"asdas","code":"asd","status":"1"},{"id":"17","pid":"0","type":"my check","code":"mt","status":"1"}]';
$.each($.parseJSON(json), function() {
alert(this.id + " " + this.type);
});

var json =
[
{"id":"1","pid":"0","type":"Individual","code":"i","status":"1"},
{"id":"2","pid":"0","type":"Group","code":"g","status":"1"},
{"id":"15","pid":"0","type":"asdasd","code":"asd","status":"1"},
{"id":"16","pid":"0","type":"asdas","code":"asd","status":"1"},
{"id":"17","pid":"0","type":"my check","code":"mt","status":"1"}
];
$.each(json,function(i,el)
{
alert(el.id+' - '+el.type);
});
Hereis that stupid example running
这是运行的愚蠢示例
EDIT:

As enoyhssaid this could also be achieved with pure javascript which would be a faster solution. Hereis a benchmark of looping arrays in javascript vs jQuery:
正如enoyhs所说，这也可以通过纯javascript来实现，这将是一个更快的解决方案。 这是 javascript 与 jQuery 中循环数组的基准测试：

Snippet to create new array of objects that only contain id and type keys:
创建仅包含 id 和 type 键的新对象数组的片段：
var json = [{"id":"1","pid":"0","type":"Individual","code":"i","status":"1"},{"id":"2","pid":"0","type":"Group","code":"g","status":"1"},{"id":"15","pid":"0","type":"asdasd","code":"asd","status":"1"},{"id":"16","pid":"0","type":"asdas","code":"asd","status":"1"},{"id":"17","pid":"0","type":"my check","code":"mt","status":"1"}];
var arr = [];
$.each(json, function(key, value){
arr.push({
id: value.id,
type: value.type
});
});
console.log(arr);

Try:
尝试：
<script type="text/javascript">
$(document).ready(function () {
var x = { "A" : {"A1": "1" } };
$.each(x, function(i,v) {
alert(i);
console.log(i);
});
});
</script>
