Get json value from response
提问by slandau
{"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}
If I alert the response data I see the above, how do I access the id
value?
如果我提醒响应数据,我看到了上述内容,我该如何访问该id
值?
My controller returns like this:
我的控制器返回如下:
return Json(
new {
id = indicationBase.ID
}
);
In my ajax success I have this:

success: function(data) {
var id = data.id.toString();
}
It says data.id
is undefined
.

If response is in json and not a string then
如果响应在 json 而不是字符串中,则
alert(response.id);
or
alert(response['id']);
otherwise
除此以外
var response = JSON.parse('{"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}');
response.id ; //# => 2231f87c-a62c-4c2c-8f5d-b76d11942301

Normally you could access it by its property name:
通常你可以通过它的属性名称访问它:
var foo = {"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"};
alert(foo.id);
or perhaps you've got a JSON string that needs to be turned into an object:
或者您可能有一个需要转换为对象的 JSON 字符串:
var foo = jQuery.parseJSON(data);
alert(foo.id);

Use safely-turning-a-json-string-into-an-object
使用安全地将 json-string-into-an-object
var jsonString = '{"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}';
var jsonObject = (new Function("return " + jsonString))();
alert(jsonObject.id);

var results = {"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}
console.log(results.id)
=>2231f87c-a62c-4c2c-8f5d-b76d11942301
results

If the response is in json then it would be like:
如果响应在 json 中,那么它将类似于:
alert(response.id);
Otherwise
除此以外
var str='{"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}';
