how can i get an attribute value of all links on a page?

Question

i'm trying to get a list of values of 'data-ctorig' property on all links marked with 'gs-title' class on this page.

i can get one the value of first link document.querySelector('a.gs-title').getAttribute('data-ctorig') but can have others. also, i can get a list of nodelist (idk what is this) using document.querySelectorAll('a.gs-title') but i dont know how can i get a list of attribute values based in this node list.

also i've tried use :nth-of-type() but i got only null after first value

var x = document.querySelector("a.gs-title:nth-of-type(1)").getAttribute("data-ctorig")

i'm also using python with selenium webdriver to do this so if someone know how to do it on python 'll help me on the same way.

Answer 1

You meant this? :)

 var links = document.querySelectorAll('a.gs-title'); var list = []; links.forEach((link) => { list.push(link.getAttribute('data-ctorig')); }); console.log(list); 

 <a class="gs-title" data-ctorig="Test1"><b>AMANDA</b> MIZUKAMI</a> <a class="gs-title" data-ctorig="Test2"><b>AMANDA</b> MIZUKAMI</a> <a class="gs-title" data-ctorig="Test3"><b>AMANDA</b> MIZUKAMI</a> 

Answer 2

First use querySelectorAll to get all the .gs-title nodes.

var gstitles = document.querySelectorAll('a.gs-title')

You can use gstitles.length now to determine how many there are.

gstitles.length;

Next we need to setup a for loop. Check out the code snippet below.

for (i=0;i<gstitles.length;i++) 
{
console.log(gstitles[i].getAttribute('data-ctorig'));
}

 var gstitles = document.querySelectorAll('a.gs-title') for (i=0;i<gstitles.length;i++) { console.log(gstitles[i].getAttribute('data-ctorig')); }
