Replace all occurences of “-” between numbers with “:” in javascript

Question

I have a string which looks like this:

1,87-99,88:12,sds-554,sdsd,787,99-145

If a "-" appears in the middle of 2 numbers, I want to change it to a ":". What is the shortest way to do this in javascript? Thanks for help.

Answer 1

try:

text='1,87-99,88:12,sds-554,sdsd,787,99-145';
tex2=text.replace(/(\d)-(\d)/g,'$1:$2');
console.log(tex2);

Answer 2

Here's my variant.

var a = '1,87-99,88:12,sds-554,sdsd,787,99-145'
var b = a.replace(/(\d)-(\d)/g,'$1:$2')

$1 and $2 puts matched digits back into string.

Answer 3

Try

'1,87-99,88:12,sds-554,sdsd,787,99-145'.replace(/(\d)-(\d)/g, '$1:$2'));​

Answer 4

var a = '1,87-99,88:12,sds-554,sdsd,787,99-145'
var b = a.replace(/(\d)-(\d)/g, '$1:$2');

"b" will give you what you want
