Question

In javascript, If i have a text block like so

Line 1
Line 2
Line 3

What would i need to do to lets say delete the first line and turn it into:

Line 2
Line 3

Answer 1

The cleanest way of doing this is to use the split and join functions, which will let you manipulate the text block as an array of lines, like so:

// break the textblock into an array of lines
var lines = textblock.split('\n');
// remove one line, starting at the first position
lines.splice(0,1);
// join the array back into a single string
var newtext = lines.join('\n');
