When iteration is involved, it is inevitable that there will be abnormal terminations or forced skips. In jQuery's each function, the following relationships exist:
The continue: return true;
Break: return false.
Direct return also pops out of jQuery.

Set the drop-down list to select and terminate the iteration
$("#area option").each(function(){ 
$(this).attr("selected", "selected");// 
return false;
