Question

Is there a way to use a wildcard in a javascript bookmarklet?

For example, I have this:

javascript:(function(){var b=document.getElementsByName('send');for(var j=0;j<b.length;j++){if(b[j].value.match(/^Send Pattarapim a Thank you gift$/i)){b[j].click();break;}}})()

That worked great when the item was for “Pattarapim”. But that “name” will change each time. Could I do anything to make that JS work regardless of what was in place of Pattarapim?

Thank You!

Answer 1

You can change the regex from

/^Send Pattarapim a Thank you gift$/i

to

/^Send .* a Thank you gift$/i

The . means “match any character here”, and the * following it means “match zero or more of the preceding thing”. So combined they mean, “match zero or more of any character here.” (Or you might use + instead of *; + means “match one or more”.) Note that that may be too broad, it depends on the text you’ll be processing, but since you’re starting with a ^, that tends to anchor it a bit and it’ll probably be fine.
