How to test if a URL string is absolute or relative - JavaScript?
To test for a URL string, use regular expression.
Example
Following is the code −
var regularExpressionForURL = /^https?:\/\//i;
var originalURL1 = "https://www.example.com/index";
var originalURL2 = "/index";
if (regularExpressionForURL.test(originalURL1)) {
console.log("This is absolute URL");
}
else {
console.log("This is relative URL");
}
if (regularExpressionForURL.test(originalURL2)) {
console.log("This is absolute URL");
}
else {
console.log("This is relative URL");
}To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo266.js
Output
This will produce the following output on console −
PS C:\Users\Amit\javascript-code> node demo266.js This is absolute URL This is relative URL
