?>

回答1:

See the problem?

...
success: function(data){ 
    $("#result").data($data); 
}
...

You take the data as data but try to access it as $data, which is a different, uninitialized variable.

Also, you cannot use .val() on an a element, use .html() instead to get the inner HTML. You probably want to use .html() instead of .data() on #result also.

Otherwise your example seems all right.

回答2:

it should be:

success: function(data) {

    $("#result").html(data);
}

回答3:

Looks like you've got an extra dollar sign on the $data variable, should be:

success: function(data) {
    $("#result").data(data);
}
