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

Posted by Tom Kaufman

Assigning value of a prompt to an element.

I'm a bit lost here. It seems straightforward enough but I'm getting an error.

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

//Select Input with the id of #fullName
var $InputFullName=$("input#fullName")
//Insert value in to full name input
$InputFullName=fullName.val();
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>

:point_right: Your usage of val isn't quite right.

When you use val for setting, you attach the method name directly to the element that you want to set. Then, you pass the value that you want to give it as an argument. You won't need an assignment operator (=).

Check the jQuery documentation for further info and usage examples.

Adding an example: var fullName = prompt("What is your full name?"); //Store the result from the promp in the variable

var $InputFullName=$("#fullName"); //Store the jQuery object in $InputFullName

$InputFullName.val(fullName); //Use the .val() method to change the input value.
