JavaScript submit form on click

Forms: event and method submit

The submit event triggers when the form is submitted, it is usually used to validate the form before sending it to the server or to abort the submission and process it in JavaScript.

The method form.submit() allows to initiate form sending from JavaScript. We can use it to dynamically create and send our own forms to server.

Let’s see more details of them.

Event: submit

There are two main ways to submit a form:

Both actions lead to submit event on the form. The handler can check the data, and if there are errors, show them and call event.preventDefault() , then the form won’t be sent to the server.

Both actions show alert and the form is not sent anywhere due to return false :

 First: Enter in the input field  
Second: Click "submit": 

When a form is sent using Enter on an input field, a click event triggers on the .

That’s rather funny, because there was no click at all.

Method: submit

To submit a form to the server manually, we can call form.submit() .

Then the submit event is not generated. It is assumed that if the programmer calls form.submit() , then the script already did all related processing.

Sometimes that’s used to manually create and send a form, like this:

let form = document.createElement('form'); form.action = 'https://google.com/search'; form.method = 'GET'; form.innerHTML = ''; // the form must be in the document to submit it document.body.append(form); form.submit();

Tasks

Modal form

Create a function showPrompt(html, callback) that shows a form with the message html , an input field and buttons OK/CANCEL .

• A user should type something into a text field and press Enter or the OK button, then callback(value) is called with the value they entered.
• Otherwise if the user presses Esc or CANCEL, then callback(null) is called.

In both cases that ends the input process and removes the form.

• The form should be in the center of the window.
• The form is modal. In other words, no interaction with the rest of the page is possible until the user closes it.
• When the form is shown, the focus should be inside the for the user.
• Keys Tab / Shift + Tab should shift the focus between form fields, don’t allow it to leave for other page elements.

showPrompt("Enter something
. smart :)", function(value) < alert(value); >);

P.S. The source document has HTML/CSS for the form with fixed positioning, but it’s up to you to make it modal.

A modal window can be implemented using a half-transparent that covers the whole window, like this:

Because the covers everything, it gets all clicks, not the page below it.

Also we can prevent page scroll by setting body.style.overflowY=’hidden’ .

The form should be not in the , but next to it, because we don’t want it to have opacity .

JavaScript Submit Form on Click

1. Submit a Form by Clicking a Link and Using the submit() Function in JavaScript
2. Submit a Form by Clicking a Button and Using the submit() Function in JavaScript

This tutorial will discuss how to submit a form using the submit() function in JavaScript.

Submit a Form by Clicking a Link and Using the submit() Function in JavaScript

In JavaScript, you can create a form using the form tag, you can give the form an id using the id attribute, and after that, you have to choose a method to submit your form like, you can submit the form when a link or a button is clicked. Now, there are two methods to submit a form, and you can either do it inside the HTML code by using the onclick attribute or do it inside the JavaScript. For example, let’s submit a form inside the HTML using the onclick attribute. See the code below.

form id="FormId">  a href="FormLink" id = "LinkID" onclick="document.getElementById('FormId').submit();"> SubmitForm a>  form> 

You can change the form id and the link id in the above code according to your requirements. This method is not recommended because you are mixing HTML with JavaScript code. You can also do that separately in JavaScript by using the id of both form and link. For example, let’s do the above operation using separate JavaScript. See the code below.

var myform = document.getElementById("FormId"); document.getElementById("LinkId").addEventListener("click", function ()   myform.submit(); >); 

This method is recommended because the HTML and JavaScript are in separate files. Note that you have to use the form id and link id that you have defined in the HTML to get those elements in JavaScript. The form will be submitted when the link is clicked.

Submit a Form by Clicking a Button and Using the submit() Function in JavaScript

You can use a button to submit a form. There are two methods to submit a form, and you can either do it inside the HTML code by using the onclick attribute or do it inside the JavaScript. For example, let’s submit a form inside the HTML using the onclick attribute. See the code below.

form id="FormId">  button id = "ButtonId" onclick="document.getElementById('FormId').submit();"> SubmitForm button>  form> 

Similar to the above method, this method is not recommended because you are mixing HTML with JavaScript code. Let’s do the above operation using separate JavaScript.

var myform = document.getElementById("FormId"); document.getElementById("ButtonId").addEventListener("click", function ()   myform.submit(); >);

JavaScript Submit Form Onclick

In this tutorial we will show you the solution of JavaScript submit form onclick, now to submit form with the help of JavaScript we have to first create a form then we have to write some codes in JavaScript so that after clicking on button our form gets submitted.

So, below we are going to show you an example and let us see the example for better understanding.

Step By Step Guide On JavaScript Submit Form Onclick :-

First question arises here that why we need to create JSON object in JavaScript.

This is because to use array in our codes again we have to stringify the array.

So, without doing that we can create JSON object directly. Below we are going to show an example in which we understand how to create JSON object in JavaScript.

So, without wasting more time let us see the codes for better understanding.

        
TalkersCode
 
JavaScript submit form on click
 
 Enter your name here: 
  
Enter Your Email id here: 
  
Enter Your Password here: 
 
 
Submit Data 
 function formSubmission ()  

1. As we here see that we today write only JavaScript codes in our example.
2. In previous tutorials, we already many times create a full code example in which we first create an HTML form with its basic structure. Inside that structure, we use HTML, head, title, body, and script tags.
3. Now, one thing to note here that JavaScript codes are always written under script tag. Whereas script tag is a paired tag. So, let us see the above codes given in script tag to see how to submit form using onclick with the help of JavaScript.
4. Now, inside above example you see that we create a form there with the help of form tag. And inside this form we create some inputs like name, email, and password. And after this we create a button to submit form.
5. Now, after creating a form we write some JavaScript codes inside the JavaScript codes we create a function that gets called when we click on the button, you can see the onclick function that we applied on button. And then when we click the button our function gets called. Inside this function we get the form by using getdocumentbyid and then submit the form using submit() function.
6. After submission of form we can also alert data or can save the data into database. There is already some articles of us with help of which you can see how to save data into database using JavaScript, but this is remaining work. And we have done the concept of submit form using onclick in JavaScript.

Conclusion :-

At last, in conclusion, here we can say that with the help of this article we can understand how submit form by onclick using JavaScript.

I hope this tutorial on JavaScript submit form onclick helps you and the steps and method mentioned above are easy to follow and implement.

submit

Событие submit возникает, когда пользователь отправляет валидную форму. Если форма невалидна и её нельзя отправить, то и submit не будет.

Как пишется

На submit можно подписаться и отреагировать, например, сказать спасибо:

 document.addEventListener('submit', function ()  alert('Спасибо, что заполнили форму!')>) document.addEventListener('submit', function ()  alert('Спасибо, что заполнили форму!') >)    Скопировать Скопировано Не удалось скопировать   

Как понять

Пользователь может отправить форму (и создать для нас событие submit ) разными способами. Например, нажать клавишу Enter внутри поля или кликнуть по кнопке .

Если мы вытащим, например, кнопку из формы, то событие submit при клике на кнопку уже не произойдёт, потому что связи с формой больше нет. В то же время, нажатие Enter внутри поля будет работать.

    Нажмите Enter в поле:   Или кликните тут  div> form> label for="input-field">Нажмите Enter в поле:label> input id="input-field" type="text"> form> div> div> button>Или кликните тутbutton> div>    Скопировать Скопировано Не удалось скопировать

🛠 За отправкой формы лучше всегда наблюдать через подписку именно на событие submit .

Это удобнее и правильнее, ведь submit связан сразу с каждым элементом формы, а пользователь может отправить её разными способами. Например, нажать на клавишу Enter в поле ввода и не трогать вовсе красивую кнопку подтверждения. В то же время подписка на другие события, например на click по кнопке, будет лишь косвенно связано с отправкой формы.

В примере ниже подпишемся на событие click по кнопке формы и выведем сообщение с названием элемента, на котором сработает click . Попробуйте нажать Enter внутри поля ввода ⌨️.

 const button = document.getElementById('submit-button') button.addEventListener('click', function (event)  alert(`Событие поймано на $`)>) const button = document.getElementById('submit-button') button.addEventListener('click', function (event)  alert(`Событие поймано на $event.currentTarget>`) >)    Скопировать Скопировано Не удалось скопировать   

Хотя мы не трогаем кнопку, событие click на ней всё равно возникает. При отправке формы браузер «синтетически» кликает по кнопке на случай, если какое-то действие привязано к ней, а не к submit . Но выходит мы работаем с одним элементом, а событие возникает на другом.

Иначе с submit — мы точно работаем с формой в целом вместо отдельных элементов и улучшаем доступность для пользователей без мыши.

Как выполнить onclick и submit одновременно?

Артём Сергеев: а что у Вас по клику должно случиться? Какая-то анимация или изменение значение полей в форме?

Артём Сергеев: тогда я советую вам сменить тип кнопки на button, а после отправления ajax запроса в callback засунуть submit формы. Так и запрос успеет уйти и форма успешно отправится.

 function one() < document.getElementById('snd').submit(); return false; >function two() 

Как я понял, Вы хотите сначала выполнить действия с объектом #savers по нажатию, а потом отправить форму. Судя по всему используется jQuery, тогда я бы сделал так:

и

$('#submit-test').on('click', function(event) < // Отменяем отправку по нажатию. event.preventDefault(); // Тут выполняем нужные действия: // инициируем нажатие на объект #savers. $('#savers').trigger('click'); // Отправляем форму. $(this).closest('form').submit(); >);
