Can someone help me understand, why is my switch case returning the default value. Even when I change all values it only returns the default at first I thought it was a hoisting issue in my code but after debugging it's I found it's the statement, it ignores all other cases. (p.s please don't be mean I just want to understand, the other examples I've seen aren't simply explained and don't have much up votes so I did try.)
var shippingMethod = document.querySelector("[name=r_method]:checked").value;
var shippingChoice;
switch(shippingMethod) {
case "usps":
shippingChoice = 2;
break;
case "ups":
shippingChoice = 3;
break;
default:
shippingChoice = 0;
break;
}
console.log(shippingChoice);I would suggest adding an if statement to verify there is a value for shippingMethod. As well, when querying for the value, make sure to include quote ("") around the value of the name.
var shippingMethod = "default";
var shippingChoice;
if (document.querySelector('[name="r_method"]:checked') != null)
{
shippingMethod = document.querySelector('[name="r_method"]:checked').value;
}
switch(shippingMethod) {
case "usps":
shippingChoice = 2;
break;
case "ups":
shippingChoice = 3;
break;
default:
shippingChoice = 0;
break;
}
console.log(shippingChoice);
