How to remove part of string in javascript

Question

I have a string btnHome . How can I remove btn and only get Home from it in javascript / jQuery?

I used slice like str.slice(3, -1) but it gives me Hom whereas I need Home .

Answer 1

Remove the -1 part (just use str.slice(3) ).

The -1 argument says slice to 1 character from the end of the string .

Answer 2

Try like

alert(str.slice(3));

Need not to give -1 there.So it will slice it from starting of the string.

Answer 3

两种简单的方法可以做到这一点：

str.split('btn')[1]; // Home

str.slice(3); // Home

Answer 4

您应该使用substr（）方法：

  target.substr(3);

Answer 5

Demo

  var txt="btnHome";
  txt.slice(3,txt.length)

By using substring

 txt.substring(3,txt.length);
