Get input field value by appending properties within a JSON object?

Question

I'm wondering if this is at all possible to do...

Essentially I'm storing information of the form (i.e. select, input, textarea) within a json object.

var inputs = {
    "name": {
        errorMsg: "Please enter a name!",
        inputName: "name",
        inputType: "input"
    }
}

From there, I want to construct the input value with jQuery such as:

$('input#name').val();

and have it actually return the value of the input field.

I was thinking of maybe doing something like this:

var inType = inputs.name.inputType;
var inName = inputs.name.inputName;
var stringType = $("'" + inType + "#" + inName + "'");
alert(stringType.val());

But that gives me an undefined value.

Here is the html I'm using:

 <input name="name" id="name" value="test" />

I've noticed that if I add add to the json object: value: $('input#name').val() after inputType and then go alert(inputs.name.value) it gives me the proper value. So should I construct the string and then prop it to the my inputs object?

var stringType = $("'" + inType + "#" + inName + "'");

The quotes are not necessary. this should be:

var stringType = $(inType + "#" + inName);

use this:

var inType = inputs.name.inputType;
var inName = inputs.name.inputName;

var selector = inType + '#' + inName ;
var stringType = $(selector);
