Form Action Attribute in JavaScript

1. Form action Attribute in JavaScript
2. Another Example Using Form action JavaScript
3. Alternative Way to Use Form Action Attribute in JavaScript

This article explains JavaScript’s form action attribute. It accesses the form, gets values of all fields, validates form data, and sends it to the right destination. Let’s look at what these action attributes are and how they work.

We can create a form in this way.

form action="/signup" method="post" id="signup">  form> 

Form action Attribute in JavaScript

The action attribute specifies where to send the form data when submitted.

action Attribute Values

1. Absolute URL — it points to another website (like action=»https://www.delftstack.com/tutorial/javascript» )
2. Relative URL — it points to a file within a website (like action=»example.htm» )

Form action Attribute Example Using HTML

Send the form data to a given link to process the input on submitting.

form action="https://www.delftstack.com" method="get">  label for="firstname">First name:label>  input type="text" id="firstname" name="firstname">br>br>  label for="lastname">Last name:label>  input type="text" id="lastname" name="lastname">br>br>  input type="submit" value="Submit">  form> 

Another Example Using Form action JavaScript

The following example includes an HTML from using a form action attribute.

 html lang="en">  head>  title>Form action javascripttitle>  style>  form label    display: inline-block;  width: 100px;  >   form div    margin-bottom: 10px;  >  style>  head>  body>  div class="p-2">  form id="myForm">  div>  label>Name:label>  input id="name" name="name" type="text">  div>  div>  label>Email:label>  input id="email" name="email" type="email">  div>  div>  input id="submit" type="submit">  div>  form>  div>  body>  script>  // setting action on window onload event  window.onload = function ()   setAction('action.php');  >;  // this event is used to get form action as an alert which is set by setAction function by using getAction function  document.getElementById('submit').addEventListener('click', function (e)   e.preventDefault();  getAction();  >);  // this function is used to set form action  function setAction(action)   document.getElementById('myForm').action = action;  return false;  >  // this function is used to get form action assigned by setAction function in an alert  function getAction()   var action = document.getElementById('myForm').action ;  alert(action);  >  script> 

We have added custom form action using JavaScript in the code above.

Alternative Way to Use Form Action Attribute in JavaScript

The same results are achievable using the onsubmit event when a user submits the form.

form onsubmit="myFunction()">  div>  label>Name:label>  input id="name" name="name" type="text">  div>  div>  label>Email:label>  input id="email" name="email" type="email">  div>  div>  input id="submit" type="submit">  div>  form> 

In the example above, the onsubmit event is used to submit form data instead of the form action attribute.

window.onload for executing as soon as page loads

Window.onload function we can use to perform some task as soon as the page finishes loading. This JavaScript function is used in different condition like displaying a print page or directing focus ( keeping the crusher blinking ) to user input field as soon as the page is loaded.

JavaScript Window onload to execute script as soon as page loads and difference between body onload

Using body tag

The other way to achieve the same result is by using onload inside body tag of the page. You can read this article on how to keep the onload event handler to set the focus on input tag once the page loads. �

Let us start some simple example of uses of window.onload function where we will display one Alert box once the page loads.
demo of window onload event →
Here is the script

Difference between window.onload function and body tag onload.

wondow.onload is executed when full page is loaded to the browser ( including all images, style , scripts ,CDN etc )
document.onload is executed when DOM is ready ( Not necessarily all connected script, images etc to be downloaded )

We can’t keep any code to access the property set or any other related objects of the elements present in body of the page by using window.onload function.

Say we want to select the text present inside a text box as soon as the page loads. This is not possible by using window.onload event but this is possible by using body onload command. The code below will generate error message.
