How can I check if variable contains Chinese/Japanese characters?

Question

How do I check if a variable contains Chinese or Japanese characters? I know that this line works:

if (document.body.innerText.match(/[\\u3400-\\u9FBF]/))
         


        

Answer 1

afaik you can to the same with a variable... document.body.innerText just returns the text of the body. Therefore you can just do

myvar.match(...)
