I'm trying to create a function in javascript that gets an alert to show up when you click the submit button. I managed to get the alert to show but it only pops up when you open the page but doesn't work when you click the submit button.
heres the function i created in javascript
function orderTics(){
//creates alert
var orderTotal=35;
alert("Your order total is $"+orderTotal);
}
I called the function in html like this:
<script>
orderTics();
</script>
I'm still very much a beginner so any and all tips will be greatly appreciated
You can use the below.
$("#FormSelector").on("submit", function() {
//Your code goes here
});
You could use the on submit function like this:
$("form.class-name").on("submit", function() {
alert("I've been submitted.");
});
Vanilla JS onsubmit event:
document.querySelector("form.class-name").addEventListener("submit", function() {
alert("I've been submitted.");
}, false);
You can also use the event.preventDefault(); method to prevent the form from going to another page, like this:
$("form.class-name").on("submit", function(event) {
even.preventDefault();
alert("Do stuff");
});
Vanilla JS onsubmit event with event.preventDefault(); method:
document.querySelector("form.class-name").addEventListener("submit", function(event) {
event.preventDefault();
alert("I've been submitted.");
}, false);
NOTE: when you use the event.preventDefault(); method the form won't redirect to the target page, even if you click the ok button in the alert box.
Finally you can just use the click event on the submit button, like this:
$("button.submit-button-class").on("click", function() {
alert("I've been clicked!");
});
Vanilla JS onclick event:
document.querySelector("button.submit-button-class").addEventListener("click", function() {
alert("I've been clicked!");
}, false);
Call your function like this:
<input type="button" value="myButton" onclick="orderTopics();">

I'm looking to add a Google Analytics event to a form that I can not access the inline html, so I can not add it as a onClick="" event straight to the html.
So my solution has been so far:
$(function() {
$(".form_submit input").on("click", function() {
dataLayer.push({
"event": "Kontakt",
"eventCategory": "Submit",
"eventAction": "Kirjuta meile",
"eventLabel": "Kirjuta meile"
});
});
});
Althought this does not seem to work as clicking the submit button possibly stops all functions and refreshes the page.
How can I run the function before submit and then submit the form after? I've been suggested using preventDefault(); and the after calling the submit again with $('form').one('submit', ... but have been unable to implement this due to lack of skill.
View site: http://avrame.com/en (the form is at the bottom of the page)
Any suggestions appreciated.
You can actually push functions to dataLayer, and it will be executed after the first event.
I would do
delegate the submit watch event to document level (see Jquery .on() submit event)
intercept the first submit, pushing event and preventing default behavior
and insert a function inside dataLayer, which submits the form again, but this time it won't be halted
The code:
window.submitGA = false;
$(function() {
$(document).on('submit','.form_submit',function(event){
if (!window.submitGA)
{
window.submitGA = true;
dataLayer.push({
"event": "Kontakt",
"eventCategory": "Submit",
"eventAction": "Kirjuta meile",
"eventLabel": "Kirjuta meile"
});
dataLayer.push(function(){
$('.form_submit').submit();
});
event.preventDefault();
}
});
});
Working solution ended up using this callback method:
var form = document.getElementsByClassName('.footer__contact form');
form.addEventListener('submit', function(event) {
event.preventDefault();
setTimeout(submitForm, 1000);
var formSubmitted = false;
function submitForm() {
if (!formSubmitted) {
formSubmitted = true;
form.submit();
}
}
ga('send', 'event', 'submit', 'Saada', 'Kirjuta meile', {
hitCallback: submitForm
});
});

<a href="#" class="submit-form show-field" data-show-field="#Product" >View products</a>
This link is dynamically added to the dom, and I fire a jQuery function on click
$('body').on("click", 'a.show-field', function(e) {
if (!$(this).attr('data-show-field')) {
return;
}
$($(this).attr('data-show-field')).parent().show();
e.preventDefault();
});
The event fires fine, but page redirects. I cant understand what I've done wrong
You event is fired before you can prevent it.
$('body').on("click", 'a.show-field', function(e) {
e.preventDefault();
if (!$(this).attr('data-show-field')) {
return;
}
$($(this).attr('data-show-field')).parent().show();
/*e.preventDefault(); */
});
If the page redirects then I think your listener is not working well.
Here you are a plunker with a use case.
With and whithout document ready
I don´t know where you put your code, but if it's outside the "document ready" that listener never fires.
$('body').on("click", 'a.show-field', function(e) {
alert("First attemp is attached");
});
$(document).ready(function() {
$('body').on("click", 'a.show-field', function(e) {
alert("Second attemp is attached");
if (!$(this).attr('data-show-field')) {
return;
}
$($(this).attr('data-show-field')).parent().show();
e.preventDefault();
});
});
PD: sorry for my english
I am using a beforeonload function but I want when the user submits the form beforeunload shouldn't work. Here is my code, which works fine in Chrome but not in Firefox.
window.form_submitted = '';
jQuery(document).ready(function() {
jQuery(window).on('beforeunload', function() {
if (form_submitted == '') {
return "Are you sure to leave that page";
}
});
});
jQuery('#form').on('submit', function (e) {
e.preventDefault();
jQuery(window).off('beforeunload');
form_submitted = 1;
site_redirect(resp.payment_url);
}
return false;
});
You have several syntax issues, and you have to place the submit block inside the DOMReady handler, otherwise JS will attempt to bind the event to an element which doesn't yet exist in the DOM. Also note you can remove the the global flag variable as you are unbinding the beforeunload event on form submission. Try this:
jQuery(document).ready(function($) {
$(window).on('beforeunload', function() {
return "Are you sure to leave that page";
});
$('#form').on('submit', function (e) {
e.preventDefault();
$(window).off('beforeunload');
site_redirect(resp.payment_url);
});
});
Also note that by doing a redirect when the form is submit (assuming that's what the site_redirect function is doing) then the content of the form will be lost.
I have this button that I can't change, nor can I edit toCashier():
<input type="button" value="Till kassan" onclick="toCashier()">
And I want to track if it's clicked and execute some javascript.
$(document).ready ( function () {
$('button[value="Till kassan"]').on('click', function(){
alert("Night button clicked");
});
});
I tried that but it doesn't seem to work. I tried various things but can't get it to work.
You have mismatched input and button, try the following :
$(document).ready ( function () {
$('input[value="Till kassan"]').on('click', function(){
alert("Night button clicked");
});
});
Or
$(document).ready ( function () {
$('input[type="button"][value="Till kassan"]').on('click', function(){
alert("Night button clicked");
});
});
button !== input
You need to use the correct selector.
$('input[value="Till kassan"]')
If you make the click with function, toCashier() function need to create :
function toCashier(){
alert("Night button clicked");
}
I have a form with a submit input and I need that when the button gets clicked, my script do some Ajax actions. Also I need to disable that button during the Ajax request. So I need a jQuery command to avoid real form submit when input is clicked. I tried to use this:
$('input.searchplease').click(function () {
$(this).attr('disabled', 'disabled');
alert('Yep');
//Do Ajax
});
This didn't worked. I mean, the alert shown correctly but form is submitted. So what is your suggestion?
Try this:
$('input.searchplease').click(function (e) {
$(this).attr('disabled', 'disabled');
alert('Yep');
//Do Ajax
e.preventDefault();
});
$('input.searchplease').click(function () {
alert('yep');
return false;
});
This should work
You can do this:
$('form').submit(function(){
... ajax things
return false;
});
I would rather not disable the button (and then enable it), unless I have to.
try this way :
$("#id-of-your-form").submit(function() {
$("#id-of-your-submit-input").attr("disabled", true);
// do-ajax
// you can use jquery's ajax complete handler to enable the submit button again
return false;
});
I think this will do the trick:
$('form').submit(function(event) {
event.preventDefault();
$('#submit-button-ID').attr('disabled', 'disabled');
$.ajax({
...,
success: function() {
$('#submit-button-ID').removeAttr('disabled');
}
});
});
