[jQuery] Re: Global Object, Scope question

[MorningZ]

simply saying

var ThisVar = whatever;

makes it "global"

so in your code, it would be like

<script type="text/javascript">
var FormData = {};

$(document).ready(function(){
       $(":input").each(function() {
             FormData[this.id] = $(this).val();
       });
});

function resetField(id) {
       if (FormData[id] != null) {
             $("#" + id).val(FormData[id]);
       }
}
</script>
