In a Tinymce textarea, it forces me to double click submit form. In the first send "var a" is empty, in the second click if you have the data and it is sent correctly. How can it be solved?

var a = document.forms["Formularioqr"]["comment"].value;
if (a == null || a == "") {
alert(a);
return false;

I haven't tried it, but i would guess, that '.value' isn't working properly for tinymce textareas.. the tinymce has an dedicated function to get the content. See https://www.tiny.cloud/blog/how-to-get-content-and-set-content-in-tinymce/
I would suggest, trying this way instead this var a = document.forms["Formularioqr"]["comment"].value;
HTML:
<form method="post" name="contact" id="frmContact" action="smail.php">
...
<label for="security" class="smallPercPadTop">Please enter the result:</label> <br /><h3 id="fNum" class="spnSecurity"></h3><h3 id="nCalcType" class="spnSecurity"></h3><h3 id="sNum" class="spnSecurity"></h3> = <input type="text" placeholder="Enter the result" name="security" id="security" class="required input_field_custom" />
<br /><br />
<input type="submit" value="Send" id="submit" name="submit" class="submit_btn" />
<input type="reset" value="Reset" id="reset" name="reset" class="submit_btn" />
</form>
Script:
$('form').on('submit', function(e) {
e.preventDefault();
var vGetResult = $("#security").val();
if (vGetResult == vResult) { //""vResult"" is a value that I set when the page loads...
alert("good");
$("#frmContact").submit();
}
});
What I am trying to do is, once I validate what the user entered is the same as another number then I would like to submit the form. Instead of submitting the form, I keep getting the alert statement infinitely.
How can I fix it?
Move e.preventDefault() to else block when the validation condition fails. Also you don't need to resubmit the form using $("#frmContact").submit()
$('form').on('submit', function(e) {
var vGetResult = $("#security").val();
if (vGetResult == vResult) { //""vResult"" is a value that I set when the page loads...
alert("good");
//$("#frmContact").submit();
}else{
e.preventDefault();
}
});
Or, you just modify statement as
$('form').on('submit', function(e) {
var vGetResult = $("#security").val();
if (vGetResult !== vResult) { //""vResult"" is a value that I set when the page loads...
e.preventDefault();
}
alert("good");
});
Your form goes in infinite loop. try this simple code.
$('form').on('submit', function(e) {
var vGetResult = $("#security").val();
if (vGetResult != vResult)
{
e.preventDefault();
}
});
Return true to allow the form to submit or false to suppress :
$('#frmContact').on('submit', function(e) {
if ($("#security").val() == vResult) {
alert("good");
return true;
} else {
return false;
}
});
Or, if the alert is not needed :
$('#frmContact').on('submit', function(e) {
return $("#security").val() == vResult;
});
You can let the jQuery event get prevented ...and trigger the native event
Just change
$("#frmContact").submit();
To
$("#frmContact")[0].submit();
I have a page where almost every click is handled by delegate().
http://itsneworleans.com/shows/midnight-menu-plus-1/blogs/after-midnight?preview=1
I set up jQuery validate like so
$(document).ready(function(){
$(".commentform form").validate({
rules: {
antispam: { equalToParam: "INO" }
}
});
jQuery.validator.addMethod("equalToParam", function(value, element, param) {
return value == param;
},
"Anti-spam field does not match requested value.");
});
if I check in console with
$.validator.methods['equalToParam']
I get back
function (value, element, param) { return value == param; }
so that looks good.
The validation works on the form submission BUT the equalToParam method has no effect. Only the "required" events occur for it.
The field HTML is
<input name="antispam" type="text" class="required" id="antispam" size="5" />
Where am I going wrong?
EDIT Here is whole form code (generated from PHP script and added to page via AJAX):
<? if ($post = (int) $_POST['pID']) { ?>
<div class="commentform">
<form>
<div class="commenttext">Comment:<br>
<textarea name="comment" class="required"></textarea>
</div>
<div class="commenttext">Your name:<br>
<input type="text" name="name" class="required">
</div>
<div class="commenttext">Your email (will not be publically visible):<br>
<input type="text" name="email" class="required email">
</div>
<div class="commenttext">Type the letters INO here to help us beat spam!<br>
<input name="antispam" type="text" class="required" id="antispam" size="5" />
</div>
<div class="commenttext">
<input type="button" name="submitcomment" class="submitcomment" value="Submit Comment">
<input type="hidden" name="post" value="<?=$post?>">
<? if ($parentComment = (int) $_POST['cID']) { ?>
<input type="hidden" name="parent" value="<?=$parentComment?>">
<? } ?>
</div>
</form>
</div>
<? } ?>
EDIT AGAIN And here's the click delegation code...
$("body").delegate(".submitcomment", "click", function(e) {
e.preventDefault();
var theform = $(this).closest("form");
console.log('Posting comment');
if ($(".commentform form").valid()) {
$.ajax({
type: "POST",
url: "/addComment.php",
data: theform.serialize()
}).done(function(html) {
if (html == 'OK') {
$(theform).html("<div class='commentposted'>Your comment has been received. Thank you. A moderator will review it for public viewing.</div>");
} else {
alert(html);
}
});
}
});
EDIT Here is the code which populates the form into the space where the Reply to Post link was:
$("body").delegate(".getcommentform", "click", function(e) {
e.preventDefault();
var pIDval = $(this).attr("data-pid");
var cIDval = $(this).attr("data-cid");
var thebox = $(this).closest("div.commentformcontainer");
console.log('Getting comment form');
$.ajax({
type: "POST",
url: "/commentForm.php",
data: { pID : pIDval, cID : cIDval }
}).done(function(html) {
thebox.html(html);
});
});
When you need to apply the .validate() method to more than one form, you must wrap it within a jQuery .each().
$(".commentform form").each(function() {
$(this).validate({
rules: {
antispam: {
equalToParam: "INO"
}
}
});
});
EDIT:
You need to initialize the plugin AFTER the form is inserted into the page. Assuming this code properly inserts the form... put your .validate() call as the last item inside...
$("body").delegate(".getcommentform", "click", function(e) {
e.preventDefault();
var pIDval = $(this).attr("data-pid");
var cIDval = $(this).attr("data-cid");
var thebox = $(this).closest("div.commentformcontainer");
console.log('Getting comment form');
$.ajax({
type: "POST",
url: "/commentForm.php",
data: { pID : pIDval, cID : cIDval }
}).done(function(html) {
thebox.html(html);
});
$(".commentform form").validate({ // <- initialize plugin AFTER form is inserted
// your rules & options
});
});
EDIT 2:
Include the equalToParam function someplace on your page within a DOM ready event handler.
How would I go about preventing the page from refreshing when pressing the send button without any data in the fields?
The validation is setup working fine, all fields go red but then the page is immediately refreshed. My knowledge of JS is relatively basic.
In particular I think the processForm() function at the bottom is 'bad'.

You can prevent the form from submitting with
$("#prospects_form").submit(function(e) {
e.preventDefault();
});
Of course, in the function, you can check for empty fields, and if anything doesn't look right, e.preventDefault() will stop the submit.
Without jQuery:
var form = document.getElementById("myForm");
function handleForm(event) { event.preventDefault(); }
form.addEventListener('submit', handleForm);
Add this onsubmit="return false" code:
<form onsubmit="return false">
That fixed it for me. It will still run the onClick function you specify.
Replace button type to button:
<button type="button">My Cool Button</button>
One great way to prevent reloading the page when submitting using a form is by adding return false with your onsubmit attribute.
<form onsubmit="yourJsFunction();return false">
<input type="text"/>
<input type="submit"/>
</form>
You can use this code for form submission without a page refresh. I have done this in my project.
$(function () {
$('#myFormName').on('submit',function (e) {
$.ajax({
type: 'post',
url: 'myPageName.php',
data: $('#myFormName').serialize(),
success: function () {
alert("Email has been sent!");
}
});
e.preventDefault();
});
});
This problem becomes more complex when you give the user 2 possibilities to submit the form:
by clicking on an ad hoc button
by hitting Enter key
In such a case you will need a function which detects the pressed key in which you will submit the form if Enter key was hit.
And now comes the problem with IE (in any case version 11)
Remark:
This issue does not exist with Chrome nor with FireFox !
When you click the submit button the form is submitted once; fine.
When you hit Enter the form is submitted twice ... and your servlet will be executed twice. If you don't have PRG (post redirect get) architecture serverside the result might be unexpected.
Even though the solution looks trivial, it tooks me many hours to solve this problem, so I hope it might be usefull for other folks.
This solution has been successfully tested, among others, on IE (v 11.0.9600.18426), FF (v 40.03) & Chrome (v 53.02785.143 m 64 bit)
The source code HTML & js are in the snippet. The principle is described there.
Warning:
You can't test it in the snippet because the post action is not
defined and hitting Enter key might interfer with stackoverflow.
If you faced this issue, then just copy/paste js code to your environment and adapt it to your context.
/*
* inForm points to the form
*/
var inForm = document.getElementById('idGetUserFrm');
/*
* IE submits the form twice
* To avoid this the boolean isSumbitted is:
* 1) initialized to false when the form is displayed 4 the first time
* Remark: it is not the same event as "body load"
*/
var isSumbitted = false;
function checkEnter(e) {
if (e && e.keyCode == 13) {
inForm.submit();
/*
* 2) set to true after the form submission was invoked
*/
isSumbitted = true;
}
}
function onSubmit () {
if (isSumbitted) {
/*
* 3) reset to false after the form submission executed
*/
isSumbitted = false;
return false;
}
}
<!DOCTYPE html>
<html>
<body>
<form id="idGetUserFrm" method="post" action="servletOrSomePhp" onsubmit="return onSubmit()">
First name:<br>
<input type="text" name="firstname" value="Mickey">
<input type="submit" value="Submit">
</form>
</body>
</html>
The best solution is onsubmit call any function whatever you want and return false after it.
onsubmit="xxx_xxx(); return false;"
Most people would prevent the form from submitting by calling the event.preventDefault() function.
Another means is to remove the onclick attribute of the button, and get the code in processForm() out into .submit(function() { as return false; causes the form to not submit. Also, make the formBlaSubmit() functions return Boolean based on validity, for use in processForm();
katsh's answer is the same, just easier to digest.
(By the way, I'm new to stackoverflow, give me guidance please. )
In pure Javascript, use: e.preventDefault()
e.preventDefault() is used in jquery but works in javascript.
document.querySelector(".buttonclick").addEventListener("click",
function(e){
//some code
e.preventDefault();
})
The best way to do so with JS is using preventDefault() function.
Consider the code below for reference:
function loadForm(){
var loginForm = document.querySelector('form'); //Selecting the form
loginForm.addEventListener('submit', login); //looking for submit
}
function login(e){
e.preventDefault(); //to stop form action i.e. submit
}
Personally I like to validate the form on submit and if there are errors, just return false.
$('form').submit(function() {
var error;
if ( !$('input').val() ) {
error = true
}
if (error) {
alert('there are errors')
return false
}
});
http://jsfiddle.net/dfyXY/
$("#buttonID").click(function (e) {
e.preventDefault();
//some logic here
}
If you want to use Pure Javascript then the following snippet will be better than anything else.
Suppose:
HTML:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Form Without Submiting With Pure JS</title>
<script type="text/javascript">
window.onload = function(){
/**
* Just Make sure to return false so that your request will not go the server script
*/
document.getElementById('simple_form').onsubmit = function(){
// After doing your logic that you want to do
return false
}
}
</script>
</head>
<body>
</body>
</html>
<form id="simple_form" method="post">
<!-- Your Inputs will go here -->
<input type="submit" value="Submit Me!!" />
</form>
Hope so it works for You!!
Just use "javascript:" in your action attribute of form if you are not using action.
In my opinion, most answers are trying to solve the problem asked on your question, but I don't think that's the best approach for your scenario.
How would I go about preventing the page from refreshing when pressing the send button without any data in the fields?
A .preventDefault() does indeed not refresh the page. But I think that a simple require on the fields you want populated with data, would solve your problem.
<form id="prospects_form" method="post">
<input id="form_name" tabindex="1" class="boxsize" type="text" name="name" placeholder="Full name*" maxlength="80" value="" required/>
<input id="form_email" tabindex="2" class="boxsize" type="text" name="email" placeholder="Email*" maxlength="100" value="" required/>
<input id="form_subject" class="boxsize" type="text" name="subject" placeholder="Subject*" maxlength="50" value="FORM: Row for OUBC" required/>
<textarea id="form_message" class="boxsize" name="message" placeholder="Message*" tabindex="3" rows="6" cols="5" maxlength="500"></textarea>
</form>
Notice the require tag added at the end of each input. The result will be the same: not refreshing the page without any data in the fields.
<form onsubmit="myFunction(event)">
Name : <input type="text"/>
<input class="submit" type="submit">
</form>
<script>
function myFunction(event){
event.preventDefault();
//code here
}
</script>
function ajax_form(selector, obj)
{
var form = document.querySelectorAll(selector);
if(obj)
{
var before = obj.before ? obj.before : function(){return true;};
var $success = obj.success ? obj.success: function(){return true;};
for (var i = 0; i < form.length; i++)
{
var url = form[i].hasAttribute('action') ? form[i].getAttribute('action') : window.location;
var $form = form[i];
form[i].submit = function()
{
var xhttp = new XMLHttpRequest();
xhttp.open("POST", url, true);
var FD = new FormData($form);
/** prevent submiting twice */
if($form.disable === true)
return this;
$form.disable = true;
if(before() === false)
return;
xhttp.addEventListener('load', function()
{
$form.disable = false;
return $success(JSON.parse(this.response));
});
xhttp.send(FD);
}
}
}
return form;
}
Didn't check how it works. You can also bind(this) so it will work like jquery ajaxForm
use it like:
ajax_form('form',
{
before: function()
{
alert('submiting form');
// if return false form shouldn't be submitted
},
success:function(data)
{
console.log(data)
}
}
)[0].submit();
it return nodes so you can do something like submit i above example
so far from perfection but it suppose to work, you should add error handling or remove disable condition
Sometimes e.preventDefault(); works then developers are happy but sometimes not work then developers are sad then I found solution why sometimes not works
first code sometimes works
$("#prospects_form").submit(function(e) {
e.preventDefault();
});
second option why not work?
This doesn't work because jquery or other javascript library not loading properly you can check it in console that all jquery and javascript files are loaded properly or not.
This solves my problem. I hope this will be helpful for you.
I hope this will be the last answer
$('#the_form').submit(function(e){
e.preventDefault()
alert($(this).serialize())
// var values = $(this).serialize()
// logic....
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="the_form">
Label-A <input type="text" name='a'required><br>
Label-B <input type="text" name="b" required><br>
Label-C <input type="password" name="c" required><br>
Label-D <input type="number" name="d" required><br>
<input type="submit" value="Save without refresh">
</form>
You can do this by clearing the state as below. add this to very beginning of the document.ready function.
if ( window.history.replaceState ) {
window.history.replaceState( null, null, window.location.href );
}
I am trying to post contact page data to my view, but it stopped working when I included if else statements.
Here is my script:
<script>
function Submit()
{
var name = document.getElementById('contact-name').value;
var email = document.getElementById ('contact-email').value;
var subject = document.getElementById ('contact-subject').value;
var message = document.getElementById ('contact-message').value;
var data = {"name":name,"email":email,"subject":subject,"message":message,csrfmiddlewaretoken:'{{ csrf_token }}'};
if (name && email && message)
{
$.ajax({ // create an AJAX call...
data: data, // get the form data
type: "POST", // GET or POST
url: "", // the file to call
dataType: "json",
success: function(response) { // on success..
alert(response['message']);
}
});
}else
{
return true;
}
}
</script>
And here is my form:
<form class="contact-form">
{% csrf_token %}
<p class="input-block">
<label for="contact-name"><strong>Name</strong> (required)</label>
<input type="text" name="name" value="" id="contact-name" required>
</p>
<p class="input-block">
<label for="contact-email"><strong>Email</strong> (required)</label>
<input type="email" name="email" value="" id="contact-email" required>
</p>
<p class="input-block">
<label for="contact-subject"><strong>Subject</strong></label>
<input type="text" name="subject" value="" id="contact-subject">
</p>
<p class="textarea-block">
<label for="contact-message"><strong>Your Message</strong> (required)</label>
<textarea name="message" id="contact-message" cols="88" rows="6" required></textarea>
</p>
<div class="hidden">
<label for="contact-spam-check">Do not fill out this field:</label>
<input name="spam-check" type="text" value="" id="contact-spam-check" />
</div>
<input type="submit" value="Submit" onclick="javascript:Submit();">
<div class="clear"></div>
</form>
Without the if else it was working fine but now all pages are reloading with all form data as query parameters. How can I correct this?
First you need to prevent the default action if you are trying to do AJAX.
Since, I see you are already using jQuery. I recommend adding the following to the top of your <script>:
$("#contact-form").submit(function(e){
e.preventDefault();
Submit();
});
Obviously, you won't need this anymore..
onclick="javascript:Submit();"
Now run this code in any sort of javascript debugger (Chrome and Safari both have good ones) and you should be good!
Try this please..i hope it works...
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$(".contact-form").submit(function(e){
e.preventDefault();
Submit();
});
});
</script>
<script>
function Submit()
{
var name = document.getElementById('contact-name').value;
var email = document.getElementById ('contact-email').value;
var subject = document.getElementById ('contact-subject').value;
var message = document.getElementById ('contact-message').value;
var data = {"name":name,"email":email,"subject":subject,"message":message,csrfmiddlewaretoken:'{{ csrf_token }}'};
if (name && email && message)
{
$.ajax({ // create an AJAX call...
data: data, // get the form data
type: "POST", // GET or POST
url: "", // the file to call
dataType: "json",
success: function(response) { // on success..
alert(response['message']);
}
});
return false;
}
}
You need to return a false from your Submit() function. Also, call the function from the form tag using onsubmit handle.
<form class="contact-form" onsubmit="Submit();">
and in Submit() function:
success: function(response) { // on success..
alert(response['message']);
}

Do not use javascript: in an onxxx event handler. javascript: is a protocol specifier that goes on a URL, but the onclick handler expects raw javascript, not a URL.
You need to return false from the onclick to prevent the default action of submitting the form. I assume you do want to prevent the default and use AJAX instead?
