How Can I Efficiently Select HTML Elements by Name Using jQuery?

Targeting Elements by Name with jQuery

jQuery's powerful selector engine allows for precise element selection. While class names offer a versatile means of targeting, this article delves into the efficient selection of elements by their name attribute.

Consider the following scenario: you need to manipulate a table column named "tcol1," expanding and hiding it dynamically. Class names prove effective when applied, but attempts to select by name fail.

To overcome this challenge, jQuery offers attribute selectors. By utilizing the "name" attribute, you can access the desired elements.

$('td[name="tcol1"]')   // Matches exactly 'tcol1'
$('td[name^="tcol"]')  // Matches those that begin with 'tcol'
$('td[name$="tcol"]')  // Matches those that end with 'tcol'
$('td[name*="tcol"]')  // Matches those that contain 'tcol'

In the provided HTML example, all three instances of the second column can be targeted using:

$('td[name="tcol1"]')

By leveraging attribute selectors, you can create precise jQuery collections based on element names, ensuring efficient element manipulation and DOM interaction.
