function waitSubmit(){

下面為jsp提交時候的js

var doSave = function(){
	$('#transitionPersonName').val($('#transitionPerson_userId option:selected').text());
	$("#nextText").val($('#nextTransaction1 option:selected').text());
	mainForm.action = "${pageContext.request.contextPath}/approval/doSave.action?flag=${param.flag}";
	waitSubmit();
	mainForm.submit();
}
