You can do this with javascript very simply by adding an onclick="click();" property to the button or link you are trying to get, then writing a small function click() { to handle the var value = document.GetElementById('textBoxId').value.

EDIT: This is to "get" a variable, not "set" a variable, but you can still use these ideas to perform an action based on the user clicking the button and then retrieving the value of the field.

jQuery is the library, ajax is not. Ajax is an implementation of the XHR Object written as a jQuery method.

$.ajax({
    type: 'POST',
    url: 'path/to/my/controller.ext',
    data: 'myvar=something'
});

PHP.

if(isset($_POST['myvar'])):
    //you now have reference to myvar, which has a value of something.
endif;
