[jQuery] Ajax firing at page load

[Greg F]

Hi,

This script (below) is firing at page load. Are there any ideas how
not to get it to fire until and event happens. Thanks for the help.

$(document).ready(function () {
if($('#DrainStackDiameter').val() != null){
$('#PowerPipeConfigurations').change(function(){ getResults
(); }).change();
$('#TotalApartmentsServed').blur(function(){ getResults(); }).blur();
$('#TotalWashroomsPerApartment').blur(function(){ getResults(); }).blur
();
$('#TotalPowerPipeUnits').blur(function(){ getResults(); }).blur();
$('#DrainStackLength').blur(function(){ getResults(); }).blur();
$('#DrainStackDiameter').change(function(){     getResults(); }).change();
}
function getResults(){
         var params = {
       PowerPipeConfigurations: $('#PowerPipeConfigurations').val(),
           TotalApartmentsServed: $('#TotalApartmentsServed').val(),
           TotalWashroomsPerApartment:$('#TotalWashroomsPerApartment').val
(),
       TotalPowerPipeUnits: $('#TotalPowerPipeUnits').val(),
       DrainStackLength: $('#DrainStackLength').val(),
       DrainStackDiameter: $('#DrainStackDiameter').val()
     };

         $('#RecommendedPowerPipeModel').load('recommend.php',params);
}
