6,122 PointsPoint of Setting a Value
Hey guys, can someone explain to me the purpose for setting a value this way? Under what circumstances would we use this method?
I'm also a little unclear on what is meant by Input here... :P
Hope these questions make sense. Thanks!

<input id="fullName" name="fullName" value="" disabled>
what the task wants you to do is to set a value for this input field. In this case it will be the value inserted in the prompt so you have to set the input value equal to the promt that is stored in the variable "fullName" like this
$('#fullName').val(fullName);
There are lots of reasons why you would want to get a value from a prompt. You may want to print the results to your page for example. Or maybe you have a story game and every user input will be added to the story.

6,122 PointsThanks for the help, but I'm still not sure I understand the difference between this and what we did in previous JS courses, where we might have written something like
var answer = prompt("Give an answer")
Is it that using jQuery methods allows us to affect our html?
