如何解析字符串的JSON对象 [英] How to parse a JSON object for a string

问题描述

我有一个JSON对象

{
    "data": [{
        "user_id":"1",
        "user_name":"test",
        "user_phone":"2147483647",
        "user_email":"[e-mail]"
    }]
}

和jQuery循环功能

and a jQuery loop function

$.each(responseData, function(index, ProfileData) {
    profiles.push(
        application.getModel("Profile", [ ProfileData.user_id, ProfileData.user_name, ProfileData.user_phone, ProfileData.user_email ] )
    );
});

但是当JSON对象变成这个时

But when the JSON object becomes this

{
    "data": [{
        "firm_id":"1",
        "firm_name":"Firm",
        "firm_phone":"2147483647",
        "firm_email":"[e-mail]"
    }]
}

然后我要检查JSON数据是否具有user或firm扩展名，并且还需要在push()中使用它.

Then I want to check whether the JSON data has user or firm extensions, and also need to use this in the push() instead.

application.getModel( "Profile", [ ProfileData.user_id, ProfileData.user_name, ProfileData.user_phone, ProfileData.user_email ] )

推荐答案

您可以像这样检查对象内部是否存在属性:

You can check for the existence of a property inside an object like so:

if('user_id' in ProfileData)

所以您的解决方案可能看起来像这样:

So your solution might look like this:

$.each(responseData, function(index, ProfileData) {
    if('user_id' in ProfileData) {
        profiles.push(
            application.getModel("Profile", [ ProfileData.user_id, ProfileData.user_name, ProfileData.user_phone, ProfileData.user_email ] );
        );
     } else {
        profiles.push(
            application.getModel("Profile", [ ProfileData.firm_id, ProfileData.firm_name, ProfileData.firm_phone, ProfileData.firm_email ] );
        );
     }
});

另一种方法是合并不同的属性，并使用定义的任意一种:

Another approach would be to coalesce the different properties, and use whichever one is defined:

$.each(responseData, function(index, ProfileData) {
    profiles.push(
        application.getModel("Profile", [ 
            ProfileData.user_id    || ProfileData.firm_id, 
            ProfileData.user_name  || ProfileData.firm_name, 
            ProfileData.user_phone || ProfileData.firm_phone, 
            ProfileData.user_email || ProfileData.firm_email
        ] );
    );
});
