How can I select an element by name with jQuery?

In jQuery, you can use the general attribute selector to target elements by their name attribute, like so:

$('[name="myElementName"]').css('border', '1px solid red');

This will select all elements whose name attribute matches "myElementName" (e.g., <input name="myElementName" />, <select name="myElementName">, etc.).

How It Works

• [name="myElementName"]: This is the attribute selector that looks for an element with a name of myElementName.
• .css('border', '1px solid red'): A simple example applying a red border to any matching element. You can use any jQuery method (.val(), .text(), .hide(), etc.) once you have your selection.

Example: Getting the Value of an Input by Name

<input type="text" name="username" placeholder="Enter your username" />

var usernameValue = $('[name="username"]').val();
console.log(usernameValue); 

This code extracts the value that the user typed in the input field named "username".

Why Use Name Selection?

• Forms: Commonly used in form handling where multiple inputs share the same name (e.g., radio buttons).
• Backwards Compatibility: Some older HTML code may rely on name instead of unique IDs.
• Efficiency: Quick way to select elements with the same name attribute without adding a new class or ID.

Bottom Line:
Simply use the jQuery attribute selector [name="something"] to select elements by their name attribute. This is particularly useful for handling groups of inputs or legacy code where name attributes are the primary identifiers.
