Rather than returning null, use a message to indicate the absence of a value in JavaScript

After successfully downloading and installing Wishlist for Shopify, everything works well. However, I encountered an issue where it displays a blank page when there are no items in the wishlist. My goal is to have it show a message like "You have no wishlist item" instead.

The current script I am utilizing is:

(Script code here)

I attempted the following solutions:

(First attempt code here)

and

(Second attempt code here)

Unfortunately, none of them worked as expected. I would appreciate any help in resolving this matter. Thank you!

Note: The initial script will not be displayed due to limitations in providing real-time coding assistance.

Answer №1

Feel free to test out the code snippet below to resolve your bug. If it doesn't work, please inform me so I can attempt an alternative approach to display an empty statement.

const showEmptyStatement = () => {
  const emptyStatement = "Your wishlist is currently empty.";
  const resetWishlist = emptyStatement;
  setWishlist([emptyStatement]);

  document.getElementById("oasis-wishlist").innerHTML = showEmptyStatement();
};

Answer №2

When fetching Wishlist products, you can include a condition to handle different scenarios. If the length of the product array is equal to 0, then set the inner HTML of Wishlist to display "Wishlist empty". Otherwise, if there is data available, you can choose how to display it. Unfortunately, I cannot provide the exact code as it may impact your existing code structure. Just implement the mentioned logic accordingly to resolve the issue in your code.

fetch(url).then((res)=>
{
if(res.data.length)
    setwihslist([res.data])
else
    wishlist.innerHTML="emptywishlist";
}
