🙋 Introduction

The formtarget attribute is a useful feature in HTML that allows developers to specify where to display the response that is received after submitting a form. This attribute can be applied to the <form> element and individual form controls, such as buttons and input fields.

By utilizing the formtarget attribute, developers can control the behavior of form submissions and decide whether the response should be displayed in the same window, a new window, or a specific frame.

🎯 Purpose of formtarget Attribute

The primary purpose of the formtarget attribute is to define the target window or frame where the response to a form submission should be displayed. By default, when a form is submitted, the response is displayed in the same window/tab. However, there are scenarios where developers may want to change this behavior, such as displaying the response in a new browser window or a specific iframe within the page.

💎 Values

The formtarget attribute accepts various values to determine the target location for displaying the form response. Some of the common values include:

_self: This is the default value. It specifies that the response should be displayed in the same window/tab that the form was submitted from.
_blank: This value opens the response in a new browser window/tab.
_parent: This value targets the parent window or frame of the current window.
_top: This value targets the top-level browsing context (the entire window).
framename: If the value is the name of a specific frame or iframe, the response is displayed in that frame.

📄 Implementation Example:

Let's illustrate the usage of the formtarget attribute with an example:

index.html

Copied

<form action="submit.php" method="post" target="_blank">
  <label for="username">Username:</label>
  <input type="text" id="username" name="username">
  
  <label for="password">Password:</label>
  <input type="password" id="password" name="password">
  
  <input type="submit" value="Submit" formtarget="_parent">
</form>

🧠 How it Works

In this example, the form has its target attribute set to "_blank", which means the response will open in a new browser window/tab by default. However, the submit button has its formtarget attribute set to "_parent", instructing the browser to display the response in the parent window instead.

🔄 Dynamic Values with JavaScript

Similar to other HTML attributes, the formtarget attribute can also be set dynamically using JavaScript. This allows developers to change the target location based on user interactions or certain conditions. Here's a basic example:

index.html

Copied

<script>
  // Dynamically set the formtarget attribute
  document.getElementById("myForm").setAttribute("formtarget", "_top");
</script>

🧠 How it Works

In this script, the formtarget attribute of a form with the id "myForm" is dynamically set to "_top", instructing the browser to display the form response in the top-level browsing context.

🏆 Best Practices

Consider the user experience and usability when choosing the target for form submissions. Opening responses in new windows or frames should be done judiciously to avoid confusing users.
Ensure compatibility with different browsers and devices, as the behavior of formtarget may vary.
Test your forms thoroughly to ensure that the desired target behavior is achieved and that the user experience is seamless.
