JQuery detects keyup() and change() for same form AJAX request

I have a search form that I want to trigger an AJAX request, which contains both <input type="text"> and <select></select> form elements.

I'd like to have the the AJAX request happen when someone starts typing, so I originally used:

$('#searchform').keyup(function() {
   //GRAB TEXT FROM INPUT AND START AJAX
});

but now the form has drop downs, so to tackle that I changed it to:

$('#searchform').change(function() {
   //GRAB VALUES FROM INPUT AND DROPDOWNS AND START AJAX
});

but that means it no longer starts the request whenever someone types anything in the <input type="text"> field until I modify something else.

Is it possible to have a function run based on whether the form "changes" or whether the input field is typed in? Should I write two functions or is there a selector that accomplishes this?

If you delegate the event, you could have your function run on both events, like so:

$('#searchform').on('keyup change', function() {
   //GRAB VALUES FROM INPUT AND DROPDOWNS AND START AJAX;
});

Just put a space between the events. Here is a quick and dirty example.

Write a function to call the ajax and pass the value as parameter

function foo(x) {
   // ajax call with x
}

$('#searchform').keyup(function() {
   //GRAB TEXT FROM INPUT AND START AJAX
   foo($(this).val());
});

$('#searchform').change(function() {
   //GRAB VALUES FROM INPUT AND DROPDOWNS AND START AJAX
   foo($(this).val());
});

You will need to listen to both events, but you can simplify this by connecting both to a single callback, namely, update.

var update = function() {
    // Handle update to form.
};

$('#searchform').keyup(update);
$('#searchform').change(update);
