HTML PushButton type Property: A Comprehensive Guide

The type property of the HTML <button> element specifies the type of button to render. For push buttons, the type attribute defines the button’s behavior within a form. Understanding the different button types is crucial for creating effective and accessible forms. This guide provides a detailed overview of the type property, its attributes, and practical examples.

What is the type Property?

The type property of the <button> element determines the button’s role and behavior. For push buttons, the most common types are button, submit, and reset. Each type has a specific function within an HTML form:

• button: A generic button that doesn’t have any default behavior. It is commonly used with JavaScript to trigger custom actions.
• submit: Submits the form data to the server. This is the default behavior if the type attribute is not specified.
• reset: Resets all the form controls to their initial values.

Syntax

The syntax for using the type property in an HTML <button> element is as follows:

<button type="button|submit|reset">Button Text</button>

Attributes

The type property accepts the following values:

Examples

Let’s explore some practical examples to demonstrate the usage of the type property.

Basic Button

A simple button that performs no action by default. JavaScript can be used to define its behavior.

<button type="button" onclick="alert('Button Clicked!')">Click Me</button>

When the button is clicked, it triggers a JavaScript alert.

Submit Button

A button that submits the form data to the server.

<form id="myForm">
  <label for="name">Name:</label>
  <input type="text" id="name" name="name" /><br /><br />
  <button type="submit">Submit</button>
</form>

When the “Submit” button is clicked, the form data is sent to the server.

Reset Button

A button that resets the form fields to their default values.

<form id="resetForm">
  <label for="email">Email:</label>
  <input type="email" id="email" name="email" value="[email protected]" /><br /><br />
  <button type="reset">Reset</button>
</form>

Clicking the “Reset” button will clear the email field and set it back to “[email protected]”.

Using button type with JavaScript for Canvas Interaction

Here’s an example that combines a button type with JavaScript to manipulate a canvas element.

<canvas id="myCanvasButtonType" width="200" height="100" style="border:1px solid #d3d3d3;">
Your browser does not support the HTML canvas tag.</canvas>
<br>
<button type="button" onclick="drawRectangle()">Draw Rectangle</button>

<script>
  function drawRectangle() {
    const canvas_buttonType = document.getElementById("myCanvasButtonType");
    const ctx_buttonType = canvas_buttonType.getContext("2d");
    ctx_buttonType.fillStyle = "green";
    ctx_buttonType.fillRect(20, 20, 150, 60);
  }
</script>

In this example, clicking the “Draw Rectangle” button executes the drawRectangle function, which draws a green rectangle on the canvas.

Tips and Best Practices

• Accessibility: Always provide meaningful text within the <button> element to ensure accessibility for users with disabilities.
• Form Submission: Use the submit type for buttons intended to submit form data. This ensures that the form is submitted correctly.
• JavaScript Interaction: For buttons that require custom behavior, use the button type and attach JavaScript event listeners.
• Reset Behavior: Use the reset type sparingly, as it can be disruptive to users if they accidentally reset their form data.
• CSS Styling: Style buttons appropriately using CSS to match the design of your website.

Conclusion

The type property of the HTML <button> element is essential for defining the behavior of buttons within a form. By understanding the different button types and their use cases, you can create more effective and user-friendly forms. Whether it’s submitting form data, resetting fields, or triggering custom JavaScript actions, the type property is a fundamental aspect of HTML form design.
