jQuery .load POST变量

I have a page where /path (a simple file that echos "test") perfectly:

$("#selector").load("/path");

but not this (it doesn't load anything):

$("#selector").load("/path", {varx:"test"});

anyone have any idea?

If nothing is being loaded, then the script is probably returning no output when the "varx" request parameter is present. Are you sure you only have:

<?php

echo 'hello';

?>

?
