I have a form which should submit data after pressing the submit button. After tagging a few input fields as required the form always shows me when there is no input in the required field after pressing the submit button - so far, so good.
What I would like to realize is that there is a redirection to another page if the submission was successful. If there are some empty required fields the form should show me, without redirecting me to another page.
By now I have the following code:
Submit button:
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" name="submityes" id="submityes" class="btn btn-danger">Submit</button>
</div>
</div>
Also I have the following js function to submit the form and to redirect me to another page:
$('document').ready(function () {
"use strict";
$(function () {
$('#submityes').click(function () {
$.ajax({
type: "POST",
/* url: "process.php", //process to mail
data: $('form.contact').serialize(), */
success: function (msg) {
window.location.replace("/submit_resolved.php");
},
error: function () {
alert("error");
}
});
});
});
});
The problem I have right now is that I will always be redirected to the "submit_resolved.php" page, whether all required fields are complete or not.
How can I solve this problem? I only want to be redirected when all required fields are not empty.
You should bind to the submit event, not click event:
UPDATED TO MATCH THE COMMENTS
$(function () {
var submityesClicked;
//catch the click to buttons
$('#submityes').click(function () {
submityesClicked = true;
});
$('#submitno').click(function () {
submityesClicked = false;
});
$('#webform').submit(function (e) {
e.preventDefault();//prevent the default action
$.ajax({
type: "POST",
/*url: "process.php", //process to mail
data: $('form.contact').serialize(),*/
success: function (msg) {
window.location.replace(submityesClicked ? "/submit_resolved_yes.php" : "/submit_resolved_no.php");
},
error: function () {
alert("error");
}
});
});
});
The submit event is triggered only if the form is valid.
Note that the submit event is triggered by the form but the click event is triggered by the input element.
Do redirection on complete. Not on success
$('document').ready(function () {
"use strict";
$(function () {
$('#submityes').click(function () {
$.ajax({
type: "POST",
/* url: "process.php", //process to mail
data: $('form.contact').serialize(), */
success: function (msg) {
//window.location.replace("/submit_resolved.php");
},
complete: function () {
window.location.replace("/submit_resolved.php");
},
error: function () {
alert("error");
}
});
});
});
});
I assume you are validating form in process.php so, you have to return error if validation fail from process.php like this.
header('HTTP/1.1 500 Internal Server Booboo');
header('Content-Type: application/json; charset=UTF-8');
die(json_encode(array('message' => 'ERROR', 'code' => 1337)));
check this link: Return errors from PHP run via. AJAX?
Hope this may be helpful to you.
The simplest thing you can do is to add "required" attribute to you input elements.Example:
<form action="/action_page.php">
Username: <input type="text" name="usrname" required>
<input type="submit">
</form>
It's a HTML5 attribute, so no JavaScript required. And it is supported by all major browsers. Check this link:
http://caniuse.com/#search=required
Anyway, you shouldn't rely just on front-end verification. Check those inputs on back-end, too.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<form action="">
Username: <input type="text" id="usrname" required>
<button type="button" name="submityes"
id="submityes" class="btn btn-danger">Submit</button>
</form>
</div>
function isValid(){
var usrname = $("#usrname").val();
if(usrname == ""){
return false;
}
return true;
}
$(function () {
$('#submityes').submit(function () {
if(isValid() == true){
$.ajax({
type: "POST",
/*url: "process.php", //process to mail
data: $('form.contact').serialize(),*/
success: function (msg) {
alert("success");
window.location.replace("/submit_resolved.php");
},
});
}else{
alert("error");
}
});
});

I am trying to submit a form using jquery. I am running a Django server.
The JS Code and HTML are as follows:
document.addEventListener('DOMContentLoaded', function() {
// Submit comment form
document.querySelector('#comment-form').addEventListener("submit", function(event){event.preventDefault()});
document.querySelector('#comment-form').addEventListener('submit', () => save_comment());
});
function save_comment() {
console.log('Save function triggered');
frm = document.querySelector('#comment-form');
data_submit = {
updated_comment: frm.querySelector('#comment-editbox').value,
month: frm.querySelector('#comment-mth').value,
gl_code: frm.querySelector('#comment-gl').value,
csrfmiddlewaretoken: jQuery("[name=csrfmiddlewaretoken]").val(),
};
console.log('Save function triggered 2');
frm.submit(function (e) {
console.log('Submit triggered');
e.preventDefault();
$.ajax({
type: frm.attr('method'),
url: frm.attr('action'),
data: data_submit,
success: function (data) {
console.log("successful");
},
error: function(data) {
console.log("failed");
}
});
console.log('save ended');
return false;
});
}
<!-- The Modal -->
<div id="myModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<label id="comment-heading">Comments <span id="comment-subheading"></span></label>
<form action="{% url 'comment' %}" method="post" id='comment-form'>
{% csrf_token %}
<textarea id="comment-editbox" name="comment-editbox"></textarea><br>
<input type="hidden" id="comment-mth" name="comment-mth" value="">
<input type="hidden" id="comment-gl" name="comment-gl" value="">
<input class="btn btn-primary" type="submit" value="Save" id='comment-save'>
</form>
</div>
</div>
"Save function triggered" and "Save function triggered 2" get logged onto the console when I submit the form. But "Submit triggered" does not.
The form does get submitted to the server which returns a json response and causes the form to navigate to the response route. I do not want the form to redirect to the response route or reload the page.
What am I doing wrong?
Why are you using?
frm.submit(function (e) {
...
});
You are calling submit method on the DOM and passing in a function to it. There is no function with submit(); Those two lines should be removed.
document.addEventListener('DOMContentLoaded', function() {
document.querySelector('#comment-form').addEventListener('submit', save_comment);
});
function save_comment(e) {
e.preventDefault();
console.log('Save function triggered');
const frm = document.querySelector('#comment-form');
const data_submit = {
updated_comment: frm.querySelector('#comment-editbox').value,
month: frm.querySelector('#comment-mth').value,
gl_code: frm.querySelector('#comment-gl').value,
csrfmiddlewaretoken: jQuery("[name=csrfmiddlewaretoken]").val(),
};
$.ajax({
type: frm.attr('method'),
url: frm.attr('action'),
data: data_submit,
success: function(data) {
console.log("successful");
},
error: function(data) {
console.log("failed");
}
});
console.log('save ended');
}
I have a form on click of submit the input box is highlighted with the red color border if it is empty. Now i have jquery ajax form submission on success of the form i will display a message "data submitted" and i will reset the form so all the input fields will be highlighted in red color. Now i want to empty the fields after the success of form submission and it should not be highlighted in red color.
HTML
(function() {
'use strict';
window.addEventListener('load', function() {
var form = document.getElementById('index-validation');
form.addEventListener('submit', function(event) {
if (form.checkValidity() === false) {

event.stopPropagation();
}
form.classList.add('was-validated');
}, false);
}, false);
})();
$(".index-form").submit(function(e) {
e.preventDefault();
return false;
}

console.log('An error occurred.');
console.log(data);

I'm not clear with your question, Do you want to reset form or remove the error class. But anyways I'll try solving out both :
SCRIPT
<script type="text/javascript">
(function() {
'use strict';
window.addEventListener('load', function() {
var form = document.getElementById('index-validation');
form.addEventListener('submit', function(event) {
if (form.checkValidity() === false) {
event.preventDefault();
event.stopPropagation();
}
form.classList.add('was-validated');
}, false);
}, false);
})();
$(".index-form").submit(function(e) {
e.preventDefault();
return false;
} else {
var ins_date=new Date($.now()).toLocaleString();
var parms = {
name : $("#name").val(),
email : $("#email").val(),
inserted_date:ins_date
};
var url2="http://localhost:3000/api";
$.ajax({
method: 'POST',
url: url2 + "/homes",
async: false,
dataType : "json",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(parms),
success: function(data){
console.log('Submission was successful.');
//if you are removing specific property from class
$(".alert-success").css('display', 'none');
$(".alert-success").fadeTo(2000, 500).slideUp(500, function(){
$(".alert-success").slideUp(500);
});
$("form")[0].reset();
console.log(data);
}, error: function (data) {
console.log('An error occurred.');
console.log(data);
},
})
}
});
</script>
Jquery doesn't support any method such as reset() of javascript, So you can trigger javascript's reset() method.
Feel free to ask doubts if stuck. Happy coding....!!!!!
$(this.('.index-form').find("input[type=text]").val("");
You can just empty the form value by giving the .val() as empty, you have to give this on after your ajax response.
and also instead of using fade in and fade out just try to use hide and show function both may work like same.
I'm trying to add validation to my ResetPassword function. validation its work fine, but I got another problem my ResetPassword function not going to work after I add validation.Can anyone direct me in the right direction? thx.
HTML code:
<div class="PopUpBG">
<div class="PopUp">
<h3 class="modal-title">
<span>Reset PAssword</span>
</h3>
<form id="form">
<input type="email" name="ResetEmail" id="ResetEmail" placeholder="Email Adresse" required/>
<input type="submit" class="btn btn-success" value="Send" onclick="ResetPassword(this)"/>
</form>
</div>
</div>
ResetPassword & validation code:
function ResetPassword(e) {
var email = $("#ResetEmail").val();
if ($("#form").validate()) {
return true;
} else {
return false;
}
$(".PopUp").html("We have sent mail to you");
$.ajax(
{
type: "POST",
url: "/Account/loginRequestResetPassword",
dataType: "json",
data: {
Email: email,
},
complete: function () {
console.log("send");
$(".PopUpBG").fadeOut();
}
})
}
The issue is because you're always exiting the function before you send the AJAX request due to your use of the return statement in both conditions of your if statement.
Change your logic to only exit the function if the validation fails:
function ResetPassword(e) {
if (!$("#form").validate())
return false;
$.ajax({
type: "POST",
url: "/Account/loginRequestResetPassword",
dataType: "json",
data: {
Email: $("#ResetEmail").val().trim(),
},
success: function() {
console.log("send");
$(".PopUp").html("We have sent mail to you");
setTimeout(function() {
$(".PopUpBG").fadeOut();
}, 10000); // fadeout the message after a few seconds
},
error: function() {
console.log('something went wrong - debug it!');
}
})
}
Also note that I amended the logic to only show the successful email message after the request completes. Your current code can show the 'email sent' message to the user, even though there is still scope for the function to fail.
I have the following form:
<form class="footer-newsletter-form" id="footer-newsletter" method="post" action="http://xxxxxx.us1.list-manage.com/subscribe/post-json?u=xxxxxxxxxxxxxxxxxxxxxxxxx&id=xxxxxxxxxx&c=?">
<input id="email" name="EMAIL" type="email" class="input-text required-entry validate-email footer__newsletter-field" value="{% if customer %}{{ customer.email }}{% endif %}" placeholder="{{ 'general.newsletter_form.email_placeholder' | t }}" aria-label="{{ 'general.newsletter_form.newsletter_email' | t }}">
<button type="submit" title="Subscribe" class="button button1 hover-white footer__newsletter-button">SUBSCRIBE</button>
<div id="subscribe-result"></div>
</form>
And the following jquery bit:
<script type="text/javascript">
$(document).ready(function () {
function register($form) {
jQuery.ajax({
type: "GET",
url: $form.attr('action'),
data: $form.serialize(),
cache : false,
dataType : 'jsonp',
contentType: "application/json; charset=utf-8",
error : function(err) { console.log('error') },
success : function(data) {
if (data.result != "success") {
console.log('success');
} else {
console.log('not success');
//formSuccess();
}
}
});
}
jQuery(document).on('submit', '.footer-newsletter-form', function(event) {
try {
var $form = jQuery(this);
event.preventDefault();
register($form);
} catch(error){}
});
});
</script>
Which submits correctly. However, when I press the submit button what I expect to happen is that the page does not refresh and when I check the browser console I'll either see "success" or "not success". Instead what happens is I'm sent to a page that displays the following JSON message: ?({"result":"success","msg":"Almost finished... We need to confirm your email address. To complete the subscription process, please click the link in the email we just sent you."}).
So how do I take that success message (or error if there's an error) and have the page not only remain as is, but also capture the success message so I can display a "Success" alert? The success alert I know how to do. I just need help having the browser remain where it is and tell the difference between success and error.
P.S. I'm not sure if this is relevant but the platform is Shopify. I don't think Shopify does anything to prevent the submission from going through as it should or the response coming back so I don't think it is relevant.
The whole issue was the $(document).ready(function () {}); part. For some reason unbeknownst to me that causes the event.preventDefault(); method from running and the form submits regularly. If you remove the $(document).ready(function () {}); part it'll work as intended.
My final code for anyone looking in the future:
Form:
<form class="footer-newsletter-form" method="POST" id="footer-newsletter" action="https://xxxxxxxxxxxxx.us1.list-manage.com/subscribe/post-json?c=?">
<input type="hidden" name="u" value="xxxxxxxxxxxxxxxxxxxxxxxxxxx">
<input type="hidden" name="id" value="xxxxxxxxxx">
<input id="email" name="EMAIL" type="email" class="input-text required-entry validate-email footer__newsletter-field">
<button type="submit" title="Subscribe" class="button button1 hover-white footer__newsletter-button">SUBSCRIBE</button>
<div id="subscribe-result"></div>
</form>
And the JS:
<script>
function register($form) {
$.ajax({
type: "GET",
url: $form.attr('action'),
data: $form.serialize(),
cache: false,
dataType: 'json',
contentType: "application/json; charset=utf-8",
error: function (err) {
console.log('error')
},
success: function (data) {
if (data.result != "success") {
console.log('Error: ' + data.msg);
} else {
console.log("Success");
$($form).find("div#subscribe-result").html("<p class='success-message'>Almost finished... We need to confirm your email address. To complete the subscription process, please click the link in the email we just sent you!</p>");
setTimeout(function() { $($form).find("div#subscribe-result").hide(); }, 7000);
}
}
});
}
$(document).on('submit', '#footer-newsletter', function (event) {
try {
var $form = jQuery(this);
event.preventDefault();
register($form);
} catch (error) {}
});
</script>
I'm having the following problem with my code below: when 'productSearchResult' is populated via AJAX, the contents are not included when the form is submitted using the 'Add' button.
UPDATE 1:
Strangely it is working, but only the first time productSearchQuery is populated. Any subsequent populations of productSearchQuery run into the problem above.
HTML:
<form name="productSearch">
<input name="productSearchQuery" type="textbox">
</form>
<form name="productAdd">
<div id="productSearchResult"></div>
</form>
<a>Add</a>
<div id="addResult"></div>
HTML loaded via AJAX into productSearchResult:
<input type="radio" name="productId" value="3944">
<input type="radio" name="productId" value="3946">
<input type="radio" name="productId" value="3999">
JS:
<script type="text/javascript">
function postData(type, url, data, targetDiv) {
$.ajax({
type: type,
url: url,
data: data,
success: function(response) {
$(targetDiv).html(response);
},
error: function() {
alert('Error! Plese try again.');
}
});
return false;
};
$(document).ready(function() {
$('input[name=productSearchQuery]').keyup(function() {
// submit the form
postData('POST', 'search.php', $('form[name=productSearch]').serialize(), '#productSearchResult');
});
$('a').click(function() {
postData('POST', 'add.php', $('form[name=productAdd]').serialize(), '#addResult');
});
});
</script>
UPDATE 2:
OK, first off I want to apologise for not including this code in my original post, I honestly didn't suspect it could be the cause. I've fixed my code after rolling back the JS which is returned with the radio buttons. I can't understand why the new JS causes the problem above, whereas the old JS does not.
Here's the old JS that works fine:
$('tr.product input[type=radio]').hide();
$('tr.product').mouseover(function() {
$(this).addClass('blueHover');
}).mouseout(function() {
$(this).removeClass('blueHover');
});
$('tr.product').click(function(event) {
$('tr.product').removeClass('blueChecked');
$(this).closest('tr').addClass('blueChecked');
if (event.target.type !== 'radio') {
$(':radio', this).attr('checked', true);
}
});
Here's the new JS that causes the problems above:
$('tr.product input[type=radio]').hide();
$(document).on({
mouseenter: function () {
$('td', $(this).parent()).addClass('blueHover');
},
mouseleave: function () {
$('td', $(this).parent()).removeClass('blueHover');
},
click: function (event) {
$('tr.product').removeClass('blueChecked');
$(this).closest('tr').addClass('blueChecked');
if (event.target.type !== 'radio') {
$(':radio', $(this).parent().parent()).attr('checked', false);
$(':radio', $(this).parent()).attr('checked', true);
}
}
}, 'tr.product td');
Try this instead
<script type="text/javascript">
function postData(type, url, data, targetDiv) {
$.ajax({
type: type,
url: url,
contentType: 'application/json',
data: data,
success: function(response) {
$(targetDiv).html(response);
},
error: function() {
alert('Error! Plese try again.');
}
});
return false;
};
$(document).ready(function() {
$('input[name=productSearchQuery]').keyup(function() {
// submit the form
postData('POST', 'search.php', $('form[name=productSearch]').serialize(), '#productSearchResult');
});
$('a').click(function() {
postData('POST', 'add.php', $('form[name=productAdd]').serialize(), '#addResult');
});
});
</script>
You have to use jQuery on method.
$('body').on('click', 'a', function() {
postData('POST', 'add.php', $('form[name=productAdd]').serialize(), '#addResult');
});
