JS load order with jQuery on load inside a function that executes immediately -

-

can this?

var myfunction = function(){     $(function(){         // jquery code here         $("#myfield").hide();     })     }();

i had code worked fine everywhere discovered worked 80% of time in ff 9.0.1. fix this:

var myfunction = function(){     $(function(){         // jquery code here         $("#myfield").hide();     })     }; myfunction();

now i'm bit puzzled why necessary

edit: can see bit confusing. maybe should have done have been instead:

var myfunction = function(){      // jquery code here     $("#myfield").hide();        };  $(function(){     myfunction(); });

the problem not correctly defining function , putting jquery code, when javascript parser reads code ignore var definition , execute jquery defined on document ready. in case don't know:

 $(function(){})  // equivalent   $(document).ready(function(){}).

the best option create function like:

 function myfunction(){        $("#myfield").hide();   }   $(function(){      //after whenever want      myfunction();   })
