Total up the cost of all items in an Amazon wishlist

gistfile1.js

var list = $$("#item-page-wrapper .list-items table tbody .lineItemMainInfo .lineItemPart strong");
var total=0;
for(i=0; i<list.length;i++){
  total += parseFloat(list[i].innerText.replace("$",""));
}
alert(list.length+" items for a total of: $"+total.toFixed(2));

Made it a bookmarklet:

javascript: (function(){
var list = document.querySelectorAll('span.a-color-price.a-size-base');
var total=0;
for(i=0; i<list.length;i++){
  total += parseFloat(list[i].innerText.replace("$",""));
}
alert(list.length+" items for a total of: $"+total.toFixed(2));
}() );

Fixed it to work when any items are unavailable:

var list = $$("span.a-size-base.a-color-price");
var total=0;
for(i=0; i<list.length;i++){
  var n = parseFloat(list[i].innerText.replace("$","").replace(",",""));  
  if(n === Number(n)) total += parseFloat(n);
}
alert(list.length+" items for a total of: $"+total.toFixed(2));

For amazon.in, the following works for me:

var list = $$('.price-section');
var total=0;
for(i=0; i<list.length;i++){
  total += (parseFloat(list[i].innerText.replace(',','')));
}
alert(list.length+" items for a total of: Rs. "+total.toFixed(2));

Here's my $0.05

var list = $$('.a-price'); var total=0; for(i=0; i<list.length;i++){ total += parseFloat(list[i].innerText.split("\n")[0].substring(1).replace(',','')); } "Total: $" + Math.ceil(total);

Paste that into the console with the relevant whishlist visible on Amazon.com and it will give you the total (rounded up to nearest dollar)

CAVEAT
If you don't scroll to the bottom before running it, you'll only get whatever is visible on screen due to dynamic loading amazon now uses.

amazon.es

var list = $$(".a-offscreen");
var total=0;
var numHidden = 0;
var temp=0;
for(i=0; i<list.length;i++){
temp = parseFloat(list[i].innerText.replace(" €","").replace(',','.'));
numHidden += isNaN(temp);
total += isNaN(temp) ? 0 : temp;
}
console.log(list.length - numHidden +" items for a total of: "+total.toFixed(2) + "€ less " + numHidden + " Hidden Items");
​

amazon br

var list = $$('.a-price'); var total=0;

for (var i = 0; i < list.length; i++) {
	total += parseFloat(list[i].innerText.split("R$")[1].replace(',','.')) ;
}

console.log("Total = " + total);

You can use the data-price attribute on the li. Tested on amazon com.

$$("li[data-price]").reduce((amount, li) => amount + parseFloat(li.getAttribute('data-price'), 0), 0.0)

This version takes into account elements without a price (such as items not available)

$$("li[data-price]").reduce((amount, li) => amount + Math.max(0, parseFloat(li.dataset['price'])), 0.0)

Latest Version:

$$('.a-price').map(_ => _.firstChild.innerText.replace('$', '')).map(_ => parseFloat(_)).reduce((a, v) => a + v)
