Question

I’m looking for a Regex that will take this:

?pm=512862895835

And turn it into this:

?pm=512862895835.png

I’d be running the expression on HTML.

Thanks,

rocky

Answer 1

You are not very clear, so I’ll assume those numbers are a variable.

So your pattern is

?pm=n

I’ll also assume

• you don’t want ones with existing .png extensions
• these may appear anywhere in a string

which means this regex will find them

/\?pm=\d+(?!\.png)/

and replace with

$0.png
