In jquery validation for textbox as numeric

To make user ID validation for only numeric values ! here is my code please suggest me where am making wrong in my code
function login() {
UserID = $('#txtLoginScreen_UserId').val();
password = $('#txtLoginScreen_MPIN').val();
if (UserID.length == 0) {
alert("Please enter User ID");
} else if (password.length == 0) {
alert("Please enter MPIN");
}
/* Here am unable to make USer ID validation for restricting only numeric values upto 12 */
/* else if (isNaN(parseInt($("#txtLoginScreen_UserId").val()))) {
alert('It must be numbers');
return false;
}*/
/* Validate for UserID */
/* $("#txtLoginScreen_UserId").keypress(function(e) {
alert("validate");
//if the letter is not digit then display error and don't type anything
if (e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57)) {
//display error message
$("#errmsg").html("Digits Only").show().fadeOut("slow");
return false;
}
});
*/
else {
}

if()$.isNumeric(UserID){
} else{
alert("not numaric");
}

Try this,
if (parseInt(UserID) > 0) {
alert("Please enter alphanumeric characters only");
}

How to validate multi-functions using Javascript in .asp

I am attempting to validate 6 functions on a form. I am getting the appropriate alerts set for each function but the form does not seem to be validating correctly and is submitting the form when the 'Generate' button is pressed.
I would be extremely grateful for any advice on this
This is how I have it set at present:
function ValidateFields(){
//Validate all Required Fields
if (RequiredTextValidate()&& CheckDateTime()&& ReasonAbsenceValidate()&&
ReturnDateChanged() && FirstDateChanged() && ActualDateChanged())return true;
}
<script type="text/javascript" language="Javascript">
function RequiredTextValidate() {
//check all required fields are completed
if (document.getElementById("<%=CompletedByTextBox.ClientID%>").value == "") {
alert("Completed by field cannot be blank");
document.getElementById("<%=CompletedByTextBox.ClientID%>").focus();
return false;
}
if (document.getElementById("<%=CompletedExtTextBox.ClientID %>").value == "") {
alert("Completed By Extension field cannot be blank");
document.getElementById("<%=CompletedExtTextBox.ClientID %>").focus();
return false;
}
if (document.getElementById("<%=EmployeeNoTextBox.ClientID %>").value == "") {
alert("Employee No field cannot be blank");
document.getElementById("<%=EmployeeNoTextBox.ClientID %>").focus();
return false;
}
if (document.getElementById("<%=EmployeeNameTextBox.ClientID %>").value == "") {
alert("Employee Name field cannot be blank");
document.getElementById("<%=EmployeeNameTextBox.ClientID %>").focus();
return false;
}
return true;
}
function CheckDateTime() {
// regular expression to match required date format
re = /^\d{1,2}\/\d{1,2}\/\d{4}$/;
if (document.getElementById("<%=SickDateTextBox.ClientID %>").value != '' && !document.getElementById("<%=SickDateTextBox.ClientID %>").value.match(re)) {
alert("Invalid date format: " + document.getElementById("<%=SickDateTextBox.ClientID %>").value);
document.getElementById("<%=SickDateTextBox.ClientID %>").focus();
return false;
}
// regular expression to match required time format
re = /^\d{1,2}:\d{2}([ap]m)?$/;
if (document.getElementById("<%=SickTimeTextBox.ClientID %>").value != '' && !document.getElementById("<%=SickTimeTextBox.ClientID %>").value.match(re)) {
alert("Invalid time format: " + document.getElementById("<%=SickTimeTextBox.ClientID %>").value);
document.getElementById("<%=SickTimeTextBox.ClientID %>").focus();
return false;
}
return true;
}
function ReasonAbsenceValidate() {
//check that reason for absence field is completed
if (document.getElementById("<%=ReasonTextBox.ClientID%>").value == "") {
alert("Reason for absence field cannot be blank");
document.getElementById("<%=ReasonTextBox.ClientID%>").focus();
return false;
}
return true;
}
function ReturnDateChanged() {
// check that either Return date or Date Unknown fields are completed
var ReturnDateValid = document.getElementById("<%=ReturnDateTextBox.ClientID%>").value;
var ReturnDateUnknown = document.getElementById("<%=ReturnUnknownCheckBox.ClientID%>").checked;
if (ReturnDateUnknown.checked)
{
ReturnDateValid.disabled = false;
ReturnDateUnknown.disabled = "disabled";
}
if (ReturnDateValid == "" && ReturnDateUnknown == "") {
alert("You must enter at least one field for anticipated return");
return false;
}
return true;
}
function FirstDateChanged() {
// check that either First date of sickness or Date Unknown fields are completed
var FirstDateValid = document.getElementById("<%=FirstDateTextBox.ClientID%>").value;
var FirstDateUnknown = document.getElementById("<%=FirstDateUnknownCheckBox.ClientID%>").checked;
if (FirstDateUnknown.checked)
{
FirstDateValid.disabled = false;
FirstDateUnknown.disabled = "disabled";
}
if (FirstDateValid == "" && FirstDateUnknown == "") {
alert("You must enter at least one field for first day of sickness");
return false;
}
return true;
}
function ActualDateChanged() {
// check that either Actual date of return or Date Unknown fields are completed
var ActualDateValid = document.getElementById("<%=ActualDateTextBox.ClientID%>").value;
var ActualDateUnknown = document.getElementById("<%=ActualDateUnknownCheckBox.ClientID%>").checked;
if (ActualDateUnknown.checked)
{
ActualDateValid.disabled = false;
ActualDateUnknown.disabled = "disabled";
}
if (ActualDateValid == "" && ActualDateUnknown == "") {
alert("You must enter at least one field for actual date of return");
return false;
}
return true;
}
function ValidateFields(){
//Validate all Required Fields
if (RequiredTextValidate()&& CheckDateTime()&& ReasonAbsenceValidate()&&
ReturnDateChanged() && FirstDateChanged() && ActualDateChanged())return true;
}
</script>

update function like following:
You need to return flase in case of invalid input to prevent form from being posted.
function ValidateFields() {
//Validate all Required Fields
if (RequiredTextValidate() && CheckDateTime() && ReasonAbsenceValidate() && ReturnDateChanged() && FirstDateChanged() && ActualDateChanged()) {
return true;
} else {
return false;
}
}
Update
if (document.getElementById("<%=SickTimeTextBox.ClientID %>").value != '' &&
!document.getElementById("<%=SickTimeTextBox.ClientID %>").value.match(re))
condition seems to be wrong. It should be like following.
if (document.getElementById("<%=SickTimeTextBox.ClientID %>").value == '' &&
!document.getElementById("<%=SickTimeTextBox.ClientID %>").value.match(re))
Use == instead of != operator.

Getting a form element to enter only at 11 characters

Right now i have it to tab on enter but i would like to get it to ONLY enter the element when there is 11 characters. How would i do it?
function getNextElement(field) {
var form = field.form;
for ( var e = 0; e < form.elements.length; e++) {
if (field == form.elements[e]) {
break;
}
}
return form.elements[++e % form.elements.length];
}
function tabOnEnter(field, evt) {
if (evt.keyCode === 13) {
if (evt.preventDefault) {
evt.preventDefault();
} else if (evt.stopPropagation) {
evt.stopPropagation();
} else {
evt.returnValue = false;
}
getNextElement(field).focus();
return false;
} else {
return true;
}
}

Maybe just something simple like that:
if(field.value.length === 11)
getNextElement(field).focus();

Event is not defined error in javascript only Firefox

I use the following script to validate the text box to enter only numbers and (.) which means it is decimal textbox validation. It was work fine in Internet Explorer and Google Chrome. If I execute the function in FireFox I get the following Error:
Event Is not Defined.
How to solve this?
function abc(event) {
if (event.keyCode > 47 && event.keyCode < 58) {
return true;
}
if (event.keyCode == 8 || event.keyCode == 46)
{
return true;
}
return false;
}
I call this function like this:
$('.decimalValidate').live('keypress',function(){
var decimalid=$(this).attr("id");
var decimalval=$('#'+decimalid).val();
var decimalvalidate=abc(decimalval);
if(decimalvalidate == false)
return false;
});
I assign this validation for text box like this:
input type="text" id="Total" class="abc"

Try this
function abc(event) {
if(!event)
event= window.event;
if (event.keyCode > 47 && event.keyCode < 58) {
return true;
}
if (event.keyCode == 8 || event.keyCode == 46)
{
return true;
}
return false;
}
and
$('.decimalValidate').live('keypress',function(e){
var decimalid=$(this).attr("id");
var decimalval=$('#'+decimalid).val();
var decimalvalidate=abc(evt); //keypress event
if(decimalvalidate == false)
return false;
});

decimalval is not an Event object, and you have to pass it to the abc function in ordert to find out which key you pressed:
$('.decimalValidate').live('keypress',function(ev){
var decimalid=$(this).attr("id");
var decimalval=$('#'+decimalid).val();
var decimalvalidate=abc(ev);
if(decimalvalidate == false)
return false;
});

$('.decimalValidate').live('keypress',function(e){
var decimalvalidate=abc(e); //this will point to the event of the keypress.
if(decimalvalidate == false)
return false;
});
I am not sure why you did all of the decimalid and decimalval operations, but if you want the event, do as I wrote in the edited code above.
Good luck.

$('.decimalValidate').on('keypress',function(event){
var decimalid = $(this).attr("id");
var decimalval = $('#'+decimalid).val();
var decimalvalidate = abc(event);
if(decimalvalidate == false)
return false;
});
function abc(event) {
if (event.keyCode > 47 && event.keyCode < 58) {
return true;
}
if (event.keyCode == 8 || event.keyCode == 46)
{
return true;
}
return false;
}
It helps you..

Javascript Focus Is Not Working on Aspx Page

Hy Guys,
Please Look at the code and Try to Help Out. The function ive written is not working but its RUNNING properly. Its about To set focus on next content on page im using it on an ASPX page. Heres my code Below :
function SetFocusOnSave(CTag,NTag)
{
alert('Running'+CTag+NTag);
var CurrentTag=document.getElementById(CTag);
var NextTag = document.getElementById(NTag);
if ( (event.keyCode==13)||(event.keyCode==9) )
{
if(CurrentTag.value=="")
{
alert("Please Enter Detail First");
CurrentTag.focus();
}
if(CurrentTag.value!="")
{
event.returnValue=true;
document.getElementById(NextTag).focus();
}
}
}
snametxt.Attributes.Add("onkeypress",
SetFocusOnSave('<%=snametxt.ClientID%>','<%=sdesctxt.ClientID%>');");

have you tried to replace
document.getElementById(NextTag).focus();
with
NextTag.focus();
?

You have to add return false; after you found the false in validation otherwise the flow will continue till end.
Try this function:
function SetFocusOnSave(CTag, NTag) {
alert('Running' + CTag + NTag);
var CurrentTag = document.getElementById(CTag);
var NextTag = document.getElementById(NTag);
if ((event.keyCode == 13) || (event.keyCode == 9))
{
if (CurrentTag.value == "")
{
alert("Please Enter Detail First");
CurrentTag.focus();
return false;
}
if (CurrentTag.value != "") {
event.returnValue = true;
NextTag.focus();
return false;
}
}
};

Hy Guys Ive Tried A NEW CODE AND Fortunately Its Working Fine Here its my Code
function Navigation(CTag, NTag, Number) {
var CurrentTag = document.getElementById(CTag);
var NextTag = document.getElementById(NTag);
var IsNumber = Number; //Checking if value is number
if (NextTag.disabled == true) {
NextTag.disabled = false;
NextTag.className = "txt";
}
if (event.keyCode == 9) {
CurrentTag.focus();
event.returnvalue = false;
}
if (event.keyCode != 9) {
if (event.keyCode == 13) {
if (IsNumber == "Y") {
if (NextTag.disabled == true) {
NextTag.disabled = false;
}
if (CurrentTag.value != "") {
NextTag.focus();
event.returnvalue = true;
}
if (CurrentTag.value == "") {
alert('Please Enter Value To Proceed Further.');
CurrentTag.focus();
event.returnvalue = false;
}
if (isNaN(CurrentTag.value)) {
alert("Please Enter A Valid Number");
CurrentTag.value = "";
CurrentTag.focus();
}
}
if (IsNumber == "N") {
if (CurrentTag.value == "") {
alert('Please Enter Value To Proceed Further.');
CurrentTag.focus();
event.returnvalue = false;
}
if (CurrentTag.value != "") {
NextTag.focus();
event.returnvalue = true;
}
}
}
}
};
Thanks ya'll !! :)
