I have a contact form with many field forms. The form sends an e-mail, and I'd like to show a div (the div has css atributes display none, visible hidden) after the submit is complet.
When I use onClick, the div appear if I click a button with all empty forms.
Any help?
My JavaScript function:
$(document).ready(function () {
$('.ipva_form_calculation').submit(function(event){
$('.ipva_result').show();
return false;
});
});
My HTML form:
<form action="http://localhost/pedespachante/" method="post" class="avia_ajax_form av-form-labels-hidden avia-builder-el-4 el_after_av_heading avia-builder-el-last ipva_form_calculation av-centered-form av-custom-form-color av-light-form" data-avia-form-id="1" data-avia-redirect="" style="display: none;">...</form>
Use jQuery submit() handler instead: https://api.jquery.com/submit/
$('#myForm').submit(function(event) {
//do some form validations
$(this).find('input[type="text"]').each(function() {
if ($(this).val() == '') {
//one or more fields is empty, hence stop here
return false;
}
});
$('.div').show();
});
Use submit event of JQuery
$('#ur_form_id').submit(function(e) {
$('.div_class_name').show();
});
here is form
<form action="http://localhost/pedespachante/" method="post" id="form_id">
<input type="text" name="contact" />
<div class="error" style="display:none;">Please Fill Contact</div>
</form>
here is jquery
$('#form_id').submit(function() {
$(this).find('input[type="text"]').each(function() {
if ($(this).val() == '') {
//one or more fields is empty, hence stop here
return false;
}
});
$('.error').show();
});
Hope its work for you!

I am trying to check if all form fields are filled on click a button & if valid then i am trying to add a check an alert using jquery.
jQuery("button#btn_place_order").click(function(event){
jQuery("form").validate({
submitHandler: function(form) {
alert('ok');
}
});
});
This is what i have tried but its not working, i just want to check if all fields are ok valid & filled & there is no form related error then just console or alert to check. Webpage has two or more html forms. Is their any way we can check using jquery ?
Thanks
First of you will have to prevent the default behavior of a form submit. Afterwards add a event listener to your button and check for validation of each input. (whatever that means for you). Is this what you wanted?
var el = document.getElementById("form");
el.addEventListener("submit", function(event) {
event.preventDefault();
}, true);
document.getElementById("btn").addEventListener("click", validate);
function validate(){
let valid = true;
[...document.getElementById("form").elements].forEach((input) => {
if(input.value.length == 0){
valid = false;
}
});
if(valid) alert("valid");
}
<form id="form">
<input type="text" name="TEST" id="test">
</form>
<button class="button" name="Send" value="Send" id="btn">Check</button>
I have one submit button, on click of which normal submission of a form should work.
I have another element, a check box on click of which I need to submit the form.
Is it possible?
If yes, how?
Javascript:
var checkbox = document.yourForm.yourCheckbox; // getting yourCheckbox
checkbox.onclick = function() { // a function that is executed when the checkbox is clicked
if (checkbox.checked == true) { // if checkbox is checked:
document.yourForm.submit(); // submit the form
}
};
HTML:
<form name="yourForm">
<input type='checkbox' name='yourCheckbox'>
</form>
http://www.w3schools.com/jsref/met_form_submit.asp
You can do something like below
<input type='checkbox' onclick='handleClick(this);'>Checkbox
function handleClick(cb) {
if(cb.checked)
{
document.getElementById("myForm").submit();
}
}
Hope this helps you.
I am checking the textbox value in javascript. and saving to database. where as my save is of submit type. I want if textbox value is greater than 100 then it should alert. and after alert , page should not submit.
Firstly, bind the click event of that button to a function. Secondly, use event.prevent default to stop that button from submitting the form. Thirdly, validate the value you want. If validated, use form id to submit the form. Something like this:
$("#ButtonId").on("click", function(event) {
event.preventDefault ? event.preventDefault() : event.returnValue = false;
if ($("#InputBoxID").val() < 100) {
$("#FormId").submit();
}
else {
alert("your message");
}
});
Above code is in jQuery, so do not forget to add the reference to jQuery.
I think you're looking for something like:
<form id="myForm" onsubmit="return validateForm();">
<input type="text" id="textfield"/>
<button type="submit">submit</button>
</form>
<script>
function validateForm(){
var value=parseInt(document.getElementById('textfield').value);
if(value>100){
alert('value is no good. larger then 100');
return false;
}
}
</script>
If you can show me your code I'd be happy to help you implementing such a feature.
Here you have an example of how to do it. I used a limit of 10 characters to make the test easier: Try if yourself
HTML:
<input type="text" id="myTextBox" onkeyup="checkValue(this)" maxlength="10"></input>
<input id="sendButton" type="submit" value="SEND"></inpu
JAVASCRIPT:
function checkValue(textbox) {
if (textbox.value.length > 10) {
alert("TEXT TOO LONG");
document.getElementById("sendButton").disabled = true;
}
else
document.getElementById("sendButton").disabled = false;
}
I'm sure I must have missed something really obvious, but can't for the life of me see what it is.
I have the below javascript, that (in theory) looks at the form when I click submit, and tells me if I have left the 'RefNo' field blank (in the final form there will be various fields to check, so I have used class='required' to identify them all). But so far, when I click submit, nothing happens (except the form is submitted with the missing data).
I've tried various options that I have found on the internet, and this seemed the most promising.
If anyone can see what I have done wrong it would be really appreciated.
<html>
<head>
<script language="JavaScript" src="jquery.js" type="text/javascript"></script>
<script type="text/javascript">
function submitForm()
{
$("#Form1").submit(function()
{
$('.required input').each(function()
{
if ($(this).val() == '')
{
$(this).addClass('highlight');
}
}
);
if ($('.required input').hasClass('highlight'))
{
alert("Please fill in a Ref Number and try again");
return false;
}
}
);
}
</script>
</head>
<body>
<form method="POST" action="test9.php" name="Form1" ID="Form1">
<input TYPE="text" ID="RefNo" NAME="RefNo" VALUE="" size="25px" class="required"></input>
</br>
<p>
<input type="submit" Name="submit" id="submitButton" value="Report History" onClick='submitForm()'></input>
</p>
</form>
</body>
Your selectors should be $('input.required'), not $('.required input').
First, I think you should use Jquery validation plugin.
Ohterwise, this code should work :
-add a onsubmit="return submitForm()" in your Form tag
<form method="POST" action="test9.php" name="Form1" ID="Form1" onsubmit="return submitForm();">
-get rid of the onclick on the submit button
-and here is the submitForm function :
function submitForm() {
var valid = true;
$('input[class="required"]').each(function() {
if ($(this).val() === '') {
alert("One field is empty and try again");
valid = false;
}
});
return valid;
}
But I really recommend jquery.validate.js
Your selector appears to be a bit off:
It should be $('.required')
The way you have it tries to select an input nested inside a Required class.
Instead of doing it on form submit, remove the submit input type from the button and just have it be a regular button.
With that in mind, your javascript should be:
<script>
$('#submitButton').click(function () {
$('input.required').each(function() {
if ($(this).val() == '') {
$(this).addClass('highlight');
}
});
if ($('.highlight').length > 0) {
alert("Please fill in a Ref Number and try again");
return false;
}
else {
$('#Form1').submit();
}
});
</script>
Otherwise, the way that you're doing it, you would have to cancel the event until you run your check for missing data, and then submit the form anyway. This way keeps you from having to cancel the action, as older IE browsers do that differently than the other browsers, and even newer versions of IE. So it makes your code more readable.
The selector should be either $('input.required') or $('#RefNo').
$('#RefNo') is more faster since it uses native getElementById method.
I am a JavaScript newbie. I have an input text field that I wish to clear after pressing the form submit button. How would I do that?
In your FORM element, you need to override the onsubmit event with a JavaScript function and return true.
<script type="text/javascript">
function onFormSubmit ()
{
document.myform.someInput.value = "";
return true; // allow form submission to continue
}
</script>
<form name="myform" method="post" action="someaction.php" onsubmit="return onFormSubmit()">
<!-- form elements -->
</form>
If a user presses the submitbutton on a form the data will be submitted to the script given in the action attribute of the form. This means that the user navigates away from the site. After a refresh (assuming that the action of the form is the same as the source) the input field will be empty (given that it was empty in the first place).
If you are submitting the data through javascript and are not reloading the page, make sure that you execute Nick's code after you've submitted the data.
Hope this is clear (although I doubt it, my English is quite bad sometimes)..
function testSubmit()
{
var x = document.forms["myForm"]["input1"];
var y = document.forms["myForm"]["input2"];
if (x.value === "")
{
alert('plz fill!!');
return false;
}
if(y.value === "")
{
alert('plz fill the!!');
return false;
}
return true;
}
function submitForm()
{
if (testSubmit())
{
document.forms["myForm"].submit(); //first submit
document.forms["myForm"].reset(); //and then reset the form values
}
}
First Name: <input type="text" name="input1"/>
<br/>
Last Name: <input type="text" name="input2"/>
<br/>
<input type="button" value="Submit" onclick="submitForm()"/>
</form>
After successfully submitting or updating form or password you can put empty value.
CurrentPasswordcontroller.state.confirmPassword = '';
