you need to set a value there as well...

$("#list").load("selectcity.php?testvar=true");

right now "testvar" is empty, so echoing it will echo an empty string... hard to see an empty string that way...

If you want the string 'testvar' to show in the URL use this:

$("#list").load("selectcity.php?testvar="+testvar);

You can also pass parameters like this:

$("#list").load("selectcity.php",{
   testvar: testvar,
   moreparam1: "some value",
   evenmore: 124
});

Because you set the variable "testvar" but do not put any thing in it.

$("#list").load("selectcity.php?testvar=foobar");

Should work.

Just try with:

$("#list").load("selectcity.php", {
    testvar: testvar
});

You didn't set the value, only the variable name in the URL.

Change to:

$("#list").load("selectcity.php?testvar=" + encodeURIComponent(testvar));
