[jQuery] Auto populate form elements using jquery, ajax, and mySQL?


Any way to autopopulate form elements using jquery and its ajax
function from a MySQL database?
Individually, I have gotten the form element to populate another
element with a submit button using the JQuery Form Plugin.
Also, I have gotten a form element to auto submit when a select option
is selected and open a new page with the populated child element.
However, I am not able to autosubmit an element and populate a second
element from a mySQL database with jQuery and Ajax (no reload).
Any suggestions or plugins?
