Need a script to validate the current catalog item is already in the cart list

[swetha53]

I have   selected a catalog item and clicked on "Add to cart" twice. catalog item was added twice to the request.In order to avoid this i need to validate on   click on                     "add to cart item" this should throw a pop-up like "Catalog item is already selected do you want to continue?"

Try this

Previously, I just had a comment snippet in there instructing you what to code in that place. This script is updated with the actual code.

function onSubmit() {

checkCart() ;

function checkCart() {
//alert('inside function');

  var catItem = gel("sysparm_id").value;

  var cart = new GlideAjax('CheckCart');

  cart.addParam('sysparm_name', 'checkCart');

cart.addParam('sysparm_catItem', catItem);

  cart.getXMLWait();

  var resp = cart.getAnswer();

  if (resp) {

// prompt user with confirm()

confirm('This item already exists in your cart - would you like to order another?');

}

// Otherwise, allow submission.

  return true;

}
}

that should be:

return confirm('This item already exists in your cart - would you like to order another?');

Sorry - I did it quick and didn't put my own comment in there   🙂   Very close but this time I get the comment even if there isn't already an item in the cart - i get it on ordernow and add to cart before I have one item there.

What value are you getting back from the script include? Can you print your resp variable? I wrote all of that really quickly as an example, so this will just confirm that it's working. Go ahead and

alert(resp);

on the line before the confirm.

Returns false
