In this I have an issue. The problem is whenever I enter any text in the captcha textbox and press enter key. Then the captcha code is changing, ie, numbers are refreshing.
Also form is getting submit and getting the message ('captcha is wrong').
Can anyone tell me how to stop form submit when we press enter key after entering captcha in textbox?
Well you could disable the Enter button on the captcha input field using jQuery.
An example being:
$('#txtInput').bind("keypress", function (e) {
if (e.keyCode == 13) return false;
});
Where keyCode == 13 is the Enter key
Update
To add the above code in your file, just copy and paste this into your html:
<script type="text/javascript">
$(document).ready(function(){
$('#txtInput').bind("keypress", function (e) {
if (e.keyCode == 13) return false;
});
});
</script>
You can do this using the following jQuery code:
$('#custRegistration').bind("keyup keypress", function(e) {
var code = e.keyCode || e.which;
if (code == 13) {
e.preventDefault();
return false;
}
});
LOL :)
AS dfsq said in comment:
"Why do you press Enter if you don't want to submit the form?"
But to block sending form with enter on input do this:
$('body').on('keydown', '#chaptcha_input', function(e) {
if(e.which == 13 && !e.shiftKey) {
e.preventDefault();
}
});
Try this
$('#txtInput').on("keyup",function(e){
if(e.keyCode == 13)
return false;
// do your stuff here if not enter key pressed
});

In the below code, after clicking on 'Save Data' I want the page to go to another htm page 'confrim.html'. Instead what is happening is its just showing "localhost:3000/confirm.html" and not opening a new page. Can anyone help to fix this, attaching the code for the reference.
I tried to implement the following through the submitInfo() function
Thanks

You could use the window.open method - like so:
function submitInfo(){
var test = document.getElementById('selTest').value;
var product = document.getElementById('selProd').value;
if( product == "EBOD" && test== "BFT" ){
window.open( "confirm.html", "Confirm", "fullscreen=yes,location=no,menubar=yes,resizable=no,scrollbars=no,status=no,toolbar=no" );
}
}
you have a
<form name="myForm" action="confirm.html" method="POST" >
which, on form submit, your browser will look for confirm.html file. I don't know whether you have file named confirm.html, but I think you do. otherwise it'll show 404 error.
As you instructed in your form, browser'll look for confirm.html, and on redirect, it'll show what's in confirm.html file.
you should remove your js script from this file and put it inside confirm.html file. or just replace action="confirm.html" with action=""
I have my HTML and JS, how would I use this form in my JS so if one of the fields are not entered, the form doesnt submit and shows me my original please enter all fields error

change your function name submit() to another because it conflict with builtin JS function, doing onclick="submit()" is same with this.form.submit() or document.getElementById('myForm').submit();

Change button type to "submit" and do validation in onsubmit event handler:
<form onsubmit="return validateMethod()" />
Move all your validation logics into validateMethod, return false if the validation is failed.
Below is an example but I think you should use a jquery lib for this:
function validateMethod(){
var inp1 = document.getElementById('input1').value;
var inp2 = document.getElementById('input2').value;
var inp3 = document.getElementById('input3').value;
if(!inp1 || !inp2 || !inp3)
{
document.getElementById('ErrorMessage').innerHTML = "Please enter all fields";
return false;
}
else{
//do your code here
document.getElementById('ErrorMessage').innerHTML = "";
return true;
}
}
You could simply use document.getElementById('myForm').addEventListener('submit', () => submit());
But you need to change <button id="submitButton" type="button" onclick="submit()"> Submit </button> to <button id="submitButton" type="submit"> Submit </button> (as Barmar said) and you also need to close your <form> tag.
Upon button click of the submission button you can iterate over all the input fields, determine whether or not they have the attribute required and then determine whether or not their value is an empty string (!field.value)
We put this in a try/catch block so that if a field is required and does not have a value, we can break out of the forEach loop by throwing an error and displaying the message Please Enter All Required Fields
let submit = document.querySelector("button");
submit.addEventListener("click", submitFn);
function submitFn() {
try {
document.querySelectorAll("form input").forEach(function(field) {
if (field.hasAttribute("required") && !field.value) {
throw error("not all fields filled in");
}
});
alert("all required fields filled in!")
} catch {
alert("please enter all required fields");
}
}
<form>
<label>first name </label><input required/>
<br/>
<label>last name</label><input required/>
<br/>
<label>email ( not required )</label><input />
<hr>
<button type="button">submit</button>
</form>
Note: It would be better code if you changed the type of the submit button to submit and changed the event from the above code from click to submit, but I've no idea if there was a reason for your markup or not so I leave that to your discretion.

How to do validation for 10 digit mobile number Using jQuery Ajax?Only numbers are allowed cannot use characters or alphanumeric characters.So how can i use jquery Ajax to do validation.I want to show on above input box that Invalid Email .and (dont want to show alert)
This will work for you...
$(document).ready(function(){
$("#mobile-num").on("blur", function(){
var mobNum = $(this).val();
var filter = /^\d*(?:\.\d{1,2})?$/;
if (filter.test(mobNum)) {
if(mobNum.length==10){
alert("valid");
$("#mobile-valid").removeClass("hidden");
$("#folio-invalid").addClass("hidden");
} else {
alert('Please put 10 digit mobile number');
$("#folio-invalid").removeClass("hidden");
$("#mobile-valid").addClass("hidden");
return false;
}
}
else {
alert('Not a valid number');
$("#folio-invalid").removeClass("hidden");
$("#mobile-valid").addClass("hidden");
return false;
}
});
});
.hidden{
display: none;

Try this code in your jquery function
var mobileNum = $(this).val();
var validateMobNum= /^\d*(?:\.\d{1,2})?$/;
if (validateMobNum.test(mobileNum ) && mobileNum.length == 10) {
alert("Valid Mobile Number");
}
else {
alert("Invalid Mobile Number");
}
Try this code. It contains the ten digits number validation for mobile:

Use this pattern only to validate Sri Lankan numbers. In above code line only validate mobile number starting with 0.

Next I click ok in the alert popup and the expected result appears:

Following is the code of my jsp where there are two input fields regNo and studentName.
I want the user to enter only numbers in regNo field. It should not contain any spaces and the length of the digits should be only 12.
I added the check for characters and I added CSS and now my Search button isn't working.

<script src="http://code.jquery.com/jquery.min.js"></script>

#mycontainer, h1, h3 {

form {

#errorMsgNumber {
display: none;
background: brown;
color: white;
}
</style>
<script>
var regNoField = document.getElementById('regNo');
var regNoMessage = document.getElementById('regNoErrorMsgNumber');
var inputFieldsButton = document.getElementById('inputFields');
regNoField.addEventListener('keydown', onChange);
function onChange(e) {
if (e.keyCode < 48 || e.keyCode > 57) {
regNoMessage.style.display = 'block'
};
if(/^\d+$/.test(regNoField.value)) {
inputFieldsButton.disabled = false;
} else {
inputFieldsButton.disabled = true;
}
}
$(document).ready(function(){
$('#inputFields').click(function(event){
if (document.getElementById('regNo').value !=""){
$("#number").submit();

I made little modification in your code. It was the ordering of javascript code. I have put your java script code after the elements. Now it will work.

You can do one more thing instead of referring the jquery from website itself you can refer the google hosting look at the link for the benefit http://encosia.com/3-reasons-why-you-should-let-google-host-jquery-for-you/
