:Reset Selector in jQuery
All elements that are specifically marked as reset buttons in your HTML document can be targeted with jQuery’s :reset selector, a specialised form selection. This indicates that it chooses any tag with the type property set to reset.
Syntax:
When using selectors with jQuery, the basic syntax is $(selector).action. This corresponds to the following for the :reset selector:
$(':reset')- jQuery is defined or accessed using the $ symbol.
- In order to locate the appropriate HTML components, the selector (‘:reset’) functions as a “query”.
- When an element or elements are selected, the jQuery action or method that will be applied is represented by.action().
How It Works
Using $(‘::reset’) allows jQuery to quickly search the Document Object Model (DOM) for every instance of . After that, it encapsulates these components into a jQuery object so you may use other jQuery functions on them. This method is a component of jQuery’s idea to enable you “write less, do more” by making basic web development tasks like event handling and HTML page browsing easier.
You can use this selector to:
Apply styles: Use styles to dynamically alter the background colour, text colour, and borders of reset buttons.
Attach event handlers: When a reset button is operated upon, such as when a user clicks it, attach event handlers to define particular actions. By resolving inconsistencies that can be a problem for web developers using plain JavaScript, jQuery’s event handling features guarantee cross-browser compatibility.
Manipulate properties: Change the reset buttons’ characteristics or properties by manipulating them.
Non-obtrusive scripting, a recommended practice in which JavaScript code is entirely isolated from HTML markup, is encouraged by this technique. You can assign events and define callback methods in a single, central area within your JavaScript code with jQuery, as opposed to explicitly inserting event handlers into HTML attributes.
Code Example
Using the :reset selector to style a reset button and add a click event handler is illustrated in this useful example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>jQuery :reset Selector Example</title>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<style>
.highlight-reset-button {
background-color: #ffdddd;
color: #333;
border: 2px solid red;
padding: 8px 12px;
font-weight: bold;
cursor: pointer;
}
</style>
</head>
<body>
<h2>Sample Form</h2>
<form id="sampleForm">
<label>Name: <input type="text" name="name"></label><br><br>
<label>Email: <input type="email" name="email"></label><br><br>
<input type="submit" value="Submit">
<input type="reset" value="Reset Form">
</form>
<script>
// Ensure DOM is fully loaded
$(document).ready(function() {
// Style the reset button
$(':reset').addClass('highlight-reset-button');
// Attach click event to reset button
$(':reset').click(function(event) {
alert("Reset button clicked. The form will be cleared.");
// To prevent form reset behavior, uncomment the next line:
// event.preventDefault();
});
});
</script>
</body>
</html>Output:
Sample Form
Name:
Email:
Submit Reset Form
In this example:
- Since $(document).ready() loads the HTML document and builds the DOM, the jQuery code is not run until then. Because jQuery cannot select and operate with elements before they are in the DOM, this is crucial.
- ‘:reset’.Using the reset button’s type, addClass(‘highlight-reset-button’); immediately picks it and gives it a custom CSS class. This shows that, if a form element has a specific type, styling it is simple and does not require the use of its id or class properties as stated in HTML.
- ‘:reset’.Click(function(event) {… }); adds a click event handler to the selected reset button. Clicking the button displays the alert. To prevent the browser’s default action (resetting form fields), use event.preventDefault().
The simple :reset selector in jQuery’s huge library of selectors and filters improves code readability and web development.
Conclusion
To sum up, jQuery’s :reset selector is a strong and effective tool that lets programmers quickly target and work with any element in an HTML document. Without depending on certain IDs or classes, developers can use this selector to apply dynamic styles, add event handlers, and change the settings of reset buttons. This improves web development’s flexibility and maintainability. Furthermore, jQuery encourages non-intrusive scripting techniques by guaranteeing a clearer distinction between JavaScript behaviour and HTML structure. All things considered, the :reset selector is a great tool for developing interactive and user-friendly web forms since it perfectly embodies jQuery’s fundamental principles of streamlining DOM manipulation and improving code readability.
