Is using custom attributes valid?

Question

I want to cancel any links and add extra attributes to each one. Below is how I\'ve achieved this.

function anularEnlaces(){
    $(\'nav a\').each(function()         


        

Answer 1

No, you should use data() instead for custom element attributes, and attr() ( or better yet prop() ) for standard html attributes .

Example of data() usage :

test

// getter
var customValue = $('a').data('custom');
var customUndefined = $('a').data('testing');

Now customValue contains "value" string, and customUndefined contains undefined

// setter
$('a').data('custom', 'test');
$('a').data('testing', true);
