Question

$('#foo').live('keyup', function (e) {
  var input = $(this).val();
  // code to process input
});

This is used in a post form and I need to run the code inside the live() when the document is ready. Is there a way, other than to wait for a key press, to invoke it?

Answer 1

$(function() { 
   // add the event
  $('#foo').live('keyup', function (e) { 
  var input = $(this).val(); 
      // code to process input 
    }); 
  $('#foo').trigger('keyup');  //trigger the event
});
