Answer 1

try :

$('input[name="project"]').val("Good Fish");

instead of:

$('input[name="project"]').val()="Good Fish";

Answer 2

The code below should work. I modified the <input> in the html to be formatted correctly as well as changed $('input[name="project"]').val()="Good Fish"; to $('input[name="project"]').val("Good Fish");

$(document).ready(function(){
    $('select[name="job_number"]').change(function() {

        $('input[name="project"]').val("Good Fish");

    });
});

<form action='project_manager' method='post'>
    <input type='text' name='project' value='show Good Fish when user picks an option' />
    <select name='job_number'>
        <option value='1'>job1</option>
        <option value='2'>job2</option>
        <option value='3'>job3</option>
    </select>
</form>
