Question

JSON response is as follows:

{"approvals": 
    [
         {"approval":
            {
               "id":"0121920",
               "key":"T100",
               "value":"Ben Tsu"
            }
         },
         {"approval":
            {
               "id":"",
               "key":"T1000",
               "value":"Amy Dong"
            }
         }
    ]
}

I’m trying to loop through all properties in the JSON file and match the value of the “key” property passed in as the parameter.

So, to the plugin I’m passing a value “T1000”. If this value exists as an approval “key” value in the JSON file, I want to display the corresponding approval “value” (in this case Amy Dong).

I’m passing inputFieldDefaultValue as a parameter to the plugin with the value being “T1000”. Hence, o.inputFieldDefaultValue.

Here’s my JQuery plugin code but it’s only spitting out object Object, object Object. So, if I have 5 “approval”, this code spits out object Object 5 times.

$.each(response.approvals, function(index, approvals){ 
    if(approvals.approval.key == o.inputFieldDefaultValue){ 
         approvals.approval.value; 
    } 
});

If I do

$.each(response.approvals, function(index, approvals){ 
    if(approvals.approval.key == o.inputFieldDefaultValue){ 
         alert(approvals.approval.value); 
    } 
});

it alerts the corresponding value (Amy Dong) but it still writes object Object (as many times as the properties in the JSON response).

What am I doing wrong?

Answer 1

If I understood you correctly, and all you need is return the value, you need something like that:

var result = null;
$.each(response.approvals, function(index, approvals){ 
    if(approvals.approval.key == o.inputFieldDefaultValue){ 
         result = approvals.approval.value; 
    } 
});
return result;

I assumed this code is inside some function which is to return the correct value.
