API trouble with jQuery / AJAX

This is my second day with jQuery & AJAX. I've done as much googleing as I know to do for this. But, with not knowing what I'm looking for, I'm lost. This is very close to working, but I can't quite figure it out.

I'm trying to use my company's ("xyz") API, and it won't work when I have the form action = a url to the page.

I've done this many times in PHP. The APIs URL is:

xyz.com/getdata.php?from=tt&isbn={variable_int}

Can someone give me a hand?

<form method="post" action="xyz.com/getdata.php" id="searchForm">
    <input type="text" name="isbn" placeholder="Search..." />
    <input class="myaccount" id="doSearch" name="doSearch" type="submit" value="Search" />
</form>

<div id="result"></div>

{literal}
<script>
  // attach a submit handler to the form
  $("#searchForm").submit(function(event) {

    // stop form from submitting normally
    event.preventDefault(); 

    // get some values from elements on the page:
    var $form = $( this ),
       term = $form.find( 'input[name="isbn"]' ).val(),
       url = $form.attr( 'action' );

    // Send the data using post and put the results in a div
//    $.开发者_运维技巧post( url, { doSearch: "Search", isbn: term } ,
    $.post( url, { from: "tt", isbn: term } ,
    function( data ) {
          var content = $( data );
          $( "#result" ).html( content );
      }
    );
  });
</script>

Thanks so much (in advance)!

Cross-domain with an AJAX request is not as easy as it seems.

Here's an interesting link you should read: http://james.padolsey.com/javascript/cross-domain-requests-with-jquery/

I'm not sure but if you use the string below

xyz.com/getdata.php?from=tt&isbn={variable_int}

the method to send data is "get". The form uses the method "post". I think there is a conflict.
