How can I get a match for this?

var str = 'https://www.example.com/cart.html?Product_Code1=&Quantity1=&';
var zR=/^https:\/\/www.example.com\/cart.html?Product_Code1=&Quantity1=&/i;
if(zR.test(str)) {
 alert('Match Found');
}

You don't need a regex for this : https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/indexOf

if( str.indexOf(url) >= 0 ) {
 alert('Match Found');
}

The reason your expression was not working is that the question mark is a special character in regex (it indicates the previous character or group is optional), so you need to escape it like the (forward-)slashes.

var zR=/^https:\/\/www.example.com\/cart.html\?Product_Code1=&Quantity1=&/i;
