Question

i am trying to prevent the form from executing if the search field is blank.

html

<form id="form" action="">
<input type="text" id="lookup"><input type="submit" id="find" value="Look Up">

</form>

jquery

$('#find').click(function(){
var s = ('#lookup').attr('value');
if(s!=""){
$.ajax({
url: result/,
type:'POST',

action="result" //form the form

$('#find').click(function(){
var s = ('#lookup').attr('value');
if(s!=""){
$("#form").submit();
}
});
