Question

I’m trying to replace all of the leading spaces in a string with something

Here’s what I tried so far

var str = '     testing    1   2   3    ',
    regex = /^\s*/,
    newStr = str.replace(regex, '.');

document.write(newStr)

I want to get a result like:

'.....testing    1   2   3    '

Is there something I’m missing?

Answer 1

Try this:

var s = "   a b c";
print(s.replace(/^\s+/, function(m){ return m.replace(/\s/g, '.');}));

which prints:

...a b c
