hi,
please refer the following code
function CheckNull()
{
var txtVolNo=null;
txtVolNo=CheckNullValue('ctl00_ContentPlaceHolder1_txtVolNo');
var txtIssueNo=null;
txtIssueNo=CheckNullValue('ctl00_ContentPlaceHolder1_txtIssueNo');
var txtIssueDate=null;
txtIssueDate=CheckNullValue('ctl00_ContentPlaceHolder1_txtIssueDate');
if (txtVolNo=='0') //NULL
{
alert('Please enter volume no.');
document.getElementById('ctl00_ContentPlaceHolder1_txtVolNo').value='';
document.getElementById('ctl00_ContentPlaceHolder1_txtVolNo').focus();
return false;
}
else if (txtVolNo!='0')
{
var VolumeNuValue=null;
VolumeNuValue=document.getElementById('ctl00_ContentPlaceHolder1_txtVolNo').value;
if (isNaN(VolumeNuValue))
{
alert('Please enter valid volume no.');
document.getElementById('ctl00_ContentPlaceHolder1_txtVolNo').focus();
return false;
}
}
if (txtIssueNo=='0')
{
alert('Please enter issue no.');
document.getElementById('ctl00_ContentPlaceHolder1_txtIssueNo').value='';
document.getElementById('ctl00_ContentPlaceHolder1_txtIssueNo').focus();
return false;
}
else if (txtIssueNo!='0')
{
var IssueNuValue=null;
IssueNuValue=document.getElementById('ctl00_ContentPlaceHolder1_txtIssueNo').value;
if (isNaN(IssueNuValue))
{
alert('Please enter valid issue no.');
document.getElementById('ctl00_ContentPlaceHolder1_txtIssueNo').focus();
return false;
}
}
