How to add remote method validation to array of inputs using class name
`

input type="text" id="ApplyAuthTCSCDT1" name="ApplyAuthTCSCDT[1]" class="form-control scdDateTime formPadding scdDataDT" required=""
input type="text" id="ApplyAuthTCSCDT2" name="ApplyAuthTCSCDT[2]" class="form-control scdDateTime formPadding scdDataDT" required=""

input type="text" id="ApplyConfirmpnSCTCDT1" name="ApplyConfirmpnSCTCDT[1]" class="form-control scdDateTime formPadding scdDataDT" required=""
input type="text" id="ApplyConfirmpnSCTCDT2" name="ApplyConfirmpnSCTCDT[2]" class="form-control scdDateTime formPadding scdDataDT" required=""

input type="text" id="RemoveAuthTCSCDT1" name="RemoveAuthTCSCDT[1]" class="form-control scdDateTime formPadding scdDataDT" required=""
input type="text" id="RemoveAuthTCSCDT2" name="RemoveAuthTCSCDT[2]" class="form-control scdDateTime formPadding scdDataDT" required=""

Have tried to use the following jquery validation rule function but getting error Uncaught TypeError: e.nodeName is undefined. Exception occurred when checking element ApplyConfirmpnSCTCDT1, check the 'remote' method. .

The following are the jquery code.

$(".scdDataDT").each(function() {
$(this).rules('add', {
required: true,
remote: {
url: "check-time.php",
type: "POST",
async: false,
data: {
scdDT: function() {
console.log($(this).val()) ;
return $( "#"+$(this).attr("id")).val();
},
pbId: function() {
return $( "#SCDApplyRemovePBId" ).val();
},
pbNo: function() {
return $( "#SCDApplyRemovePBNo" ).val();
}
}
},
messages: {
required: "*",
remote:"#"
}
});
});
