🙋 Introduction

jQuery empowers developers with robust tools for building interactive and dynamic web pages. Among these tools is the :enabled selector, which enables you to target HTML elements that are currently enabled. Understanding and utilizing this selector effectively can enhance your ability to create responsive and user-friendly web interfaces.

In this guide, we'll explore the usage of the jQuery :enabled selector with clear examples to help you grasp its significance.

🧠 Understanding :enabled Selector

The :enabled selector in jQuery allows you to select HTML elements that are currently enabled, such as input fields, buttons, and other form elements. It comes in handy when you need to perform actions or apply styles to elements based on their enabled state.

💡 Syntax

The syntax for the :enabled selector is straightforward:

syntax.js

Copied

$(":enabled")

📝 Example

Selecting Enabled Form Elements:

Suppose you have a form with input fields and buttons, and you want to select all the enabled elements. You can achieve this using the :enabled selector as follows:
index.html
Copied
```
<input type="text" id="username" disabled>
<input type="password" id="password">
<button id="submitBtn" disabled>Submit</button>
```
example.js
Copied
```
$(":enabled").each(function() {
    console.log($(this).attr('id'));
});
```
This will log the IDs of the enabled elements (password) to the console.
Styling Enabled Elements:

You can dynamically apply CSS styles to enabled elements using jQuery. For example, let's change the background color of enabled buttons:
index.html
Copied
```
<button id="submitBtn">Submit</button>
<button id="resetBtn" disabled>Reset</button>
```
example.js
Copied
```
$(":enabled").css("background-color", "lightgreen");
```
This will set the background color of the enabled button with the ID submitBtn to light green.
Handling Events on Enabled Elements:

You can bind events to enabled elements to enhance interactivity. Here's an example where we alert a message when a button is clicked:
index.html
Copied
```
<button id="submitBtn">Submit</button>
```
example.js
Copied
```
$("#submitBtn").click(function() {
    alert("Button clicked!");
});
```
Disabling Elements Programmatically:

jQuery allows you to disable elements based on certain conditions. For instance:
example.js
Copied
```
$("#disableBtn").click(function() {
    $("#submitBtn").prop("disabled", true);
});
```
This will disable the button with the ID submitBtn when a button with the ID disableBtn is clicked.

🎉 Conclusion

The jQuery :enabled selector is a valuable tool for targeting and interacting with enabled HTML elements. Whether you need to select elements, apply styles, handle events, or manipulate the enabled state programmatically, this selector provides a convenient solution.

By mastering its usage, you can create more responsive and user-friendly web interfaces with ease.
