enter activate function

Hello all i have the following:


$(document).ready(function(){
$("#getInfo").bind("click", function(){
var keyword = $("#keyword").val();
$("#content").html('Gathering data... <img src="loader.gif" />');
$.ajax({
type: "GET",
data: 'keyword=' + keyword,
url: 'proccess.php',
cache: false,
error: function(html){
$("#content").html(
"<span class=\"red\">Error: Network connection low, please try again later.</span>" + html
);},
success:
function(html){
$("#content").html(html);
}
});
});
});
setTimeout(ready, 500000);


When a button is clicked, away it goes. But if you type info in the input box, and press enter, obviously nothing happens. how do i activate function when data is inserted and then enter is pressed?

no? nobody?

$("#keyword").keyup(function(e) {
if(e.keyCode == 13) {

// do stuff


//and stop Enter submitting the form
e.preventDefault();
return false;
}
});
