推荐答案

<script language="Javascript">
__doPostBack('__Page', 'MyCustomArgument');
</script></script>

以下是解释：

[]

function ValidateMonthandYear() {
 debugger;
 var bReturn=true;
 var monthformat = { 'Jan': 01, 'Feb': 02, 'Mar': 03, 'Apr': 04, 'May': 05, 'Jun': 06, 'Jul': 07, 'Aug': 08, 'Sep': 09, 'Oct': 10, 'Nov': 11, 'Dec': 12 };

 document.getElementById('<%=lblDateofPurchaseValidation.ClientID%>').innerHTML = '';
 document.getElementById('<%=lblMonthandYearofManufacturingvalidation.ClientID%>').innerHTML = ''; 

 //this is the selected Date 
 var Manufyear = document.getElementById('<%=ddlManufatureyear.ClientID%>').value ;
 var Manufmonth = document.getElementById('<%=ddlManufaturemonth.ClientID%>').value;
 var ManufDay = document.getElementById('<%=ddlManufatureDay.ClientID%>').value;

 if (Manufyear != "0" && Manufmonth != "0" && ManufDay != "0") {
     var date = Manufyear - +Manufmonth - +ManufDay; 
 }
 else { 
     bReturn = false; 
 }

 return bReturn;
}
