JavaScript version of this jQuery line [closed]

Question

I am searching for a javascript alternative for the following code:

$('a[href*="vivo.sx/"]').attr('href')

I have never worked with javascript. This may be very simple for someone who's more experienced with javascript.

Answer 1

I've done a version that does it both way for comparison..

Please note I've used document.querySelector, not document.querySelectorAll, if you use the All variant, remember you need to loop the result.

console.log( $('a[href*="vivo.sx/"]').attr('href') );
console.log( document.querySelector('a[href*="vivo.sx/"]').href );
