I have like no JS experience, but I need help.
So I have a code that allows a user to manually enter a URL.
Well, If they leave the value blank and click out it "NULLS". I want a way to detect that null and revert back to "/" or the same page instead of /null
function url(){
swal("Enter a URL:", {
content: "input",
})
.then((value) => {
location.replace(value);
});
}
// PROD Fix, needs a zero-null failure-fix. Find a way to prevent zero-data/null.You can add a test for the null value before the location.replace() and change the value to the url you want as default.
function url(){
swal("Enter a URL:", {
content: "input",
})
.then((value) => {
if (value === null) value = "your replacement url";
location.replace(value);
});
}
Careful with the check if (value === null) if you can receive either null or an empty string. The condition will fail, if you receive an empty string.
I would use if (!value) instead to cover both null && "".
