复制代码 代码如下:

var controldate;
function checkDate(){
controldate= document.getElementById(\"sendDate\").value;
if(controldate==\"\"){
alert(\'日期不能为空\');
return false;
}else{
var day = new Date(); var Year = 0;
var Month = 0;
var Day = 0;
var CurrentDate = \"\";
//初始化时间
Year = day.getFullYear();
Month = day.getMonth()+1;
Day = day.getDate();

CurrentDate += Year + \"-\";

if (Month >= 10 )
{
CurrentDate += Month + \"-\";
}
else
{
CurrentDate += \"0\" + Month + \"-\";
}
if (Day >= 10 )
{
CurrentDate += Day ;
}
else
{
CurrentDate += \"0\" + Day ;
} //alert(CurrentDate);//当前日期

var startDate = new Date(CurrentDate.replace(\"-\",\",\")).getTime() ;
var endDate = new Date(controldate.replace(\"-\",\",\")).getTime() ; if( startDate > endDate )
{
alert(\'选择日期不能小于当前日期！\');
document.getElementById(\"sendDate\").focus();
return false;
