Sending Values With JQuery's Get Function

I am currently coding something to check my database to check for duplicate errors. It is a form and I am having the following function check for duplicate values using jQuery.get.

Solution 1:

I believe

$.get(url,{sheetnum: '$("input#sheetnum").val()'},verifyDb);

should be

$.get(url,{sheetnum: $("input#sheetnum").val()},verifyDb);
