the jscript code we have on our store website is not working properly - jscript

Question

I have this code installed on my website and what it is suppose to do is see if a product has a single or double attribute and then it disables products from there that are out of stock so customers can't click on it. The code works great for the single attribute products but it doesn't seem to work for the double attribute products.
Single Attribute Product link - https://true-grit-running-company.shoplightspeed.com/goodr-sunglasses.html
Double Attribute Product link - https://true-grit-running-company.shoplightspeed.com/womens-bondi-7.html?id=65554420&quantity=1
`
// A quick check to see if it is a product being viewed (checking the microdata) - to avoid running the rest of the code if viewing a page other than the product page
if ($('[itemtype*="//schema.org/Product"]').length > 0) {
//Check the url to see if a variant is being viewed or not
var curl = location.href;
//choose the appropriate ajax url
if (curl.indexOf('?') > -1) {
var url = curl + '&format=json';
} else {
var url = '?format=json';
}
//Start the ajax call
$.ajax({
url: url,
})
// Add the disabled attribute to the variants that aren't available
.done(function(obj) {
//create a variable with the product variants
var data = obj.product.variants;
//fun a function on each variant
$.each(data, function(index, value) {
//check if any of the variants aren't available for purchase
if (!value.stock.available) {
//CODE FOR DOUBLE ATTRIBUTE VARIANTS
//check if the variants are double attribute
if (value.title.indexOf(',') > -1) {
console.log('Double Attribute matrix!');
var attribute1 = value.title.replace(/"/g,'').split(',')[0].split(": ")[1];
//only disable the variants for which the first attribute is being viewed
if ($('select[name*="matrix"]:first()').val() == attribute1) {
var option = value.title.replace(/"/g,'').split(',')[1].split(":")[1];
$('select[name*="matrix"] option:contains(' + option + ')').each(function(){
if ($(this).text() == option) {
$(this).attr('disabled', 'true');
}
});
}
//CODE FOR SINGLE ATTRIBUTE VARIANTS
} else {
console.log('Single Attribute matrix!');
var option = value.title.split(': ')[1];
var selectname = value.title.split(': ')[0];
$('select[name*="matrix"] option:contains(' + option + ')').each(function(){
if ($(this).text() == option) {
$(this).attr('disabled', 'true');
}
});
}
}
})
});
} else {
console.log('not a product page!');
