Introduction

This article shows how to handle or target a control's attribute using jQuery. We already talked about how to modify the appearance of controls in a web page when user hovers the mouse or clicks the mouse. For this we used .addClass(), .removeClass(), .css(), .toggleClass() etc. I'm going to cover some cool stuff using a problem and solution approach. So, let's start looking at first problem.

Problem 1

If you simply want to open all URLs on a new tab, a quick jQuery code can do this using .attr() method.

Note: For more read this.

.attr() Method

.attr() gets the value of an attribute for the first element in the set of matched elements.

Problem 2

If you have a website that uses a huge list of images and you forgot to place alt (alternative) text (for when an image is not found, that will be displayed), how to fix this. I mean how you will add a brand new attribute to an existing list of controls? Don't worry, here is the fix.

Look at the result in the browser.
