Question

Im using thess functions to limit titles to 3 words:

function trim_words(text, limit){
var words = text.split(/\b[\s,\.-:;]*/,limit);
theNewString=words.join(" ");
return theNewString;
}
jQuery('#title').keyup(function(){
    jQuery(this).val(trim_words(jQuery(this).val(),3));
});

My problem is that i cant use number as separate words.
For example

“Hello my2 test”

its ok
But if i try

“Hello 2 test”

number 2 gets deleted.

I know the problem must be in the regex but i know nothing about it. I tried

text.split(/\b[\s,\.-:;\d]*/,limit);

but no luck at all.
Thanks for your help guys!

Escape the - character. [\.-:] means “everything between . and :“. which includes digits.

text.split(/\b[\s,\.\-:;]*/,limit);
