Question

why can’t i select the div i need using $.post?

trying at callback function:

$.post("file.php", { param_s: $('#input').val()},
               function(data) {
                 $('#'+donde).html(data.find('#router').html);

});

And firebug jumps:

data.find is not a function

normally i would $('#where').load('file.php?param=foo #myDiv') but this file responds by $_POST..

how can i manipulate the data response so i can filter the desired selector?

Answer 1

Since find is a jQuery method and data is not a jQuery object, find is undefined.

Simply wrap data in a jQuery object:

$.post("file.php", { param_s: $('#input').val() }, function(data) {
     $('#'+donde).html( $(data).find('#router').html() );
});
