Remove all characters before “-” on each line of multiline textarea text

Question

I am getting some text from a multiline textarea, each line is separated by a line break:

 1 - test1
 2 - test2
 3 - test3
 4 - test4

How can I remove on each line all text before the - , so the text will look like:

 test1
 test2
 test3
 test4

Answer 1

You could look for no dashes and a dash and replace with an empty string for multiline data.

 var string = ' 1 - test1\\n 2 - test2\\n 3 - test3\\n 4 - test4', result = string.replace(/^[^-]+-/gm, ''); console.log(result); 

Answer 2

You can do it using split and splice.

 const mytext = ' 1 - test1'; const arr = mytext.split('-'); const splice = arr.splice(1,1 ,''); const final = splice.toString(); console.log(final); 

Answer 3

this could be solved with a regular expression. Try to put down your string to check if it is possible.
