I have a date and I want to replace all the slashes with dots. This is what I have but it's not working:

var TheDate = "3 / 29 / 2017";
TheDate = TheDate.replace(/'/'/g,'.');
alert(TheDate);

What's not right? There's a jsFiddle here to test.

Reset to default 3

Your expression should be /\//g

var d = "3 / 29 / 2017";
d = d.replace(/\//g,'.');
document.body.append(d);

Replace /'/'/g with /[/]/g

  • / - start of the regex

  • [/] match characters inside square brackets

  • /g end of the regex

Regex resources:

  • http://regexr./

Try this TheDate.replace(/\//g, '.')

var TheDate = "3 / 29 / 2017";
TheDate = TheDate.replace(/\//g,'.');     
alert(TheDate);

You need to escape the / character. You do it by prepending it with a \.
