问题 This question already has answers here : Splitting a string into chunks by numeric or alpha character with JavaScript (3 answers) Closed 3 years ago . I'd like to split strings like 'foofo21' 'bar432' 'foobar12345' into ['foofo', '21'] ['bar', '432'] ['foobar', '12345'] Is there an easy and simple way to do this in JavaScript? Note that the string part (for example, foofo can be in Korean instead of English). 回答1: Check this sample code var inputText = "'foofo21' 'bar432' 'foobar12345'";
