The split function of a string displays an undefined result

My goal is to extract all characters that come after the equal sign within a URL:

let url = this.$route.query.item
      console.log(typeof(url)) // outputs string

     let status = url => url.split('=')[1]

When I run the code, it shows 'split' as undefined. What could be causing this issue and how can it be resolved?

Answer №1

Below is the solution you need:

const text = "hello=world";
console.log(typeof (text)) // prints string

const value = text => text.split('=')[1]

console.log(value(text));// "world"

Answer №2

It seems that the this.$route.query.item does not have an = character in it. If you are trying to get the current URL, you can try the following code snippet:

let url = this.$router.currentRoute;
console.log(url); // Check if this is the expected URL
let status = 'url does not contain = char';
if(url.includes('='){
   status = url.split('=')[1];
}
console.log(status);

Note: If you really need to split the this.$route.query.item, log it and verify if it contains an = character or consider adding a check for it.
