Split a number from a string in JavaScript [duplicate]

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'";
function processText(inputText) {
    var output = [];
    var json = inputText.split(' ');
    json.forEach(function (item) {
        output.push(item.replace(/\'/g, '').split(/(\d+)/).filter(Boolean));
    });
    return output;
}

console.log(JSON.stringify(processText(inputText)));

Second solution:

var num = "'foofo21".match(/\d+/g);
// num[0] will be 21

var letr =  "foofo21".match(/[a-zA-Z]+/g);
/* letr[0] will be foofo.
   Now both are separated, and you can make any string as you like. */

You want a very basic regular expression, (\d+). This will match only digits.

whole_string="lasd行書繁1234"
split_string = whole_string.split(/(\d+)/)
console.log("Text:" + split_string[0] + " & Number:" + split_string[1])
