The trim() method in Vue.JS does not properly handle trimming a passed string

I've been attempting to eliminate white space from a property of one of the returned objects using the .trim() function, but it's not working as expected.

Even after trying JavaScript functions like .replace(/\s/g,''), the issue persists.

<script>
export default {
    name: 'navigation',
    props: ["navigation"],
    methods:{
        whiteSpace: function(a){
            var str = a;
            str.toLowerCase();
            str.trim();
            console.log(str);


            return str;
        }
    }
}
</script>

HTML

<li>
  <router-link :to="{ path: whiteSpace(nav.linkTitle) }">
       {{nav.linkTitle}}
  </router-link>
</li>

The intended outcome is to have a string without any white space characters, however, the current implementation does not remove them effectively.

Answer №1

This piece of code demonstrates how to manipulate a string in JavaScript:

str.toLowerCase();

Instead of modifying the original value, it creates a new one. To correctly modify and log the updated string, you could follow this approach:

var str = a;
str = str.toLowerCase();
str = str.trim();
console.log(str);

Alternatively, you can simplify this process and directly return the trimmed lowercase value with the following code snippet:

export default {
    name: 'navigation',
    props: ["navigation"],
    methods: {
        whiteSpace: function (a) {
            return a.toLowerCase().trim();
        }
    }
}

When you utilize the trim method, remember that it does not alter the original object but instead generates a new string.

To implement this, simply include return str.trim().
