Setting value code challenge, jquery

I don't even know what this is asking? Can someone please rephrase what this is asking for? I have been trying to figure it out and am just blocked completely.

I know this isn't right, but I'm stumped on what to do at all.

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

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

First it's asking you to find the DOM object. We typically save this to a variable so we can access it again.

var $name =  $("#fullName");

Next the val function has two basic forms.

  1. Getting -- Takes the value out. input = $num.val();
  2. Setting -- Changes the value to something else. $num.val(input);

In this example you want to use #2, to set it to the value stored in fullName.

See if you can put it together.

Thanks, this helped me understand how val works. I find the explanations in the jquery api pretty unhelpful at this stage, but maybe it will make more sense as I go along.

I had problems with this one too, probably because the id name and the variable name were the same. It was much more simple than most of the things I was trying.

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

//Select Input with the id of #fullName
$name = $("#fullName");

//Insert value in to full name input
$name.val(fullName);

I never would have got this. I guess I didn't understand the val function after all. Still not sure I do.
