JavaScript jQuery Basics (2014) Creating a Mobile Drop Down Menu Setting a value

Code using attr() rather than val() method

This might have already been suggested, I haven't looked through every single post on this particular topic but it's a different approach to the val() method that has been suggested by most.

$("input").attr("value", fullName);

However, it's worth noting that the 'value' attribute of an input element is usually the default. I'm sure others with more jQuery expertise can expand upon this better than I as to whether this is a good or bad method for solving this challenge.

js/app.js 
//Show Prompt Window and store value
var fullName = prompt("What is your full name?");

//Select Input with the id of #fullName

//Insert value in to full name input
index.html 
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<label for="fullName">Full Name</label><input id="fullName" name="fullName" value="" disabled>
<script src="//code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>
<script src="js/app.js" type="text/javascript" charset="utf-8"></script>
</body>
</html>

I'm not familiar with '.var()'. But if you mean '.val()', it's essentially just a shorthand for '.attr("value")' and the two can be used interchangably.

Typo (now edited) :) and I appreciate the clarification. I think it's the fact that we don't need to actually select the 'value' attribute for the input element to have it's 'value' changed that seems counter intuitive, at least for me. But I like a good shorthand where it's available.
