为什么点饥后不去检验这段javascript脚本有没有什么错误啊
------解决方案--------------------这个名字(documentviewTelephoneCheckList)找不到,有关提交验证,只要验证脚本中有问题,报出错误,默认为提交,而不是验证失败,不提交,看不到错误的原因,提交后已经转向其它页面.
------解决方案--------------------查看 <s:datetimepicker name= 'toDate ' displayFormat= 'yyyy-MM-dd ' /> - <s:datetimepicker name= 'fromDate ' displayFormat= 'yyyy-MM-dd ' />
这个控件
