如何使用正则表达式计算textarea中的单词和数字？

Question

I have problem on regular expression, its like i am trying to count the number of word in text area but i am not getting desired output. The main problem is, that it does not count the numbers for example "Hello world 123" it counts only 2. and for "123" it does not count at all. my regular expression isresponse.trim().replace(/\b[\s,-:;'"_]*\b/gi, ' ').split(' ');

Answer 1

You should use /\b|\d+/gi to search for word boundaries or numbers, then count the number of elements in the array.

var array = response.trim().match(/\b|\d+/gi);
var count = array.length;
