复制代码 代码如下:

<script type="text/javascript">

function check(){

//开始时间比结束时间大的验证

var validtime = document.form1.validtime.value;

var invalidtime = document.form1.invalidtime.value;

var beginTimes=validtime.substring(0,10).split('-');

var endTimes=invalidtime.substring(0,10).split('-');

validtime=beginTimes[1]+'/'+beginTimes[2]+'/'+beginTimes[0]+'/'+ validtime.substring(10,19);

invalidtime=endTimes[1]+'/'+endTimes[2]+'/'+endTimes[0]+'/'+invalidtime.substring(10,19);

var a =(Date.parse(invalidtime)-Date.parse(validtime))/3600/1000;

if(a<0){

alert("失效时间不能小于生效时间!");

return;

}

var emergency = document.form1.emergency.value;

if(emergency==""||regnull.test(emergency)){

alert("请输紧急程度!");

document.form1.emergency.focus();
