Ajax into same page

[newtomysql]

Dear All,
I have tab when I press will call a javascript and in that I call it like this. The problem now the whole page get refresh. The tabTest1.php is the same page not another page. How can I pass the value without refreshing the page.

if(tabID=="driverDetails")
	{
		var Result = 55;
    location.href="tabTest1.php?Result=" + Result;

		document.getElementById("driverDetails").className = "show"; 
		document.getElementById("driverLicenses").className = "hide";
