How to remove whitespace from a string in typescript?

Question

In my angular 5 project, with typescript I am using the .trim() function on a string like this, But it is not removing the whitespace and also not giving any error.

this.maintabinfo = this.inner_view_data.trim().toLowerCase();
// inner_view_data has this value = "Stone setting"

https://www.typescriptlang.org/docs/handbook/release-notes/typescript-1-4.html This docs clearly say that .trim() is part of the typescript.

What is best way to remove whitespace in from a string in typescript?

Problem

The trim() method removes whitespace from both sides of a string.

Solution

You can use a Javascript replace method to remove white space like

"hello world".replace(/\s/g, "");

Example

var out = "hello world".replace(/\s/g, "");
console.log(out);

Answer 2

Trim just removes the trailing and leading whitespace. Use .replace(/ /g, "") if there are just spaces to be replaced.

this.maintabinfo = this.inner_view_data.replace(/ /g, "").toLowerCase();

Answer 3

The trim() method removes whitespace from both sides of a string.

To remove all the spaces from the string use .replace(/\s/g, "")

 this.maintabinfo = this.inner_view_data.replace(/\s/g, "").toLowerCase();
