Question

I have two strings such as:

sometext~somemoretext~extratext

and

sometext~otherextratext

I wish to crop off the last tilde (~) and all text to the right. For instance, the above two strings would result in:

sometext~somemoretext

and

sometext

Thanks

Answer 1

• lastIndexOf(char) returns the position of the last found occurrence of a specified value in a string

• substring(from, to) extracts the characters from a string, between two specified indices, and returns the new sub string

For instance:

var txt = 'sometext~somemoretext~extratext';
txt = txt.substring(0, txt.lastIndexOf('~'));
