One problem encountered:

use js Process the contained string into an array containing these numbers ？

answer ：

One 、 Use regular ： for example

var str ="d567unt7jk80o9hkghftjs123ldka78sdassdfd653";

str.match(/\d+/g);//["567", "7", "80", "9", "123", "78", "653"]

Two 、 The other is not regular , Can you write it down , For guidance

 

function test(str){

    var ret = [];

    var isNum = false;

    for(var i = 0, iLen = str.length; i < iLen; i++){

        var charCode = str.charCodeAt(i);

        if(charCode >= 48 && charCode <= 57){

            if(isNum){

                ret[ret.length - 1] += str[i];

            }else{

                ret.push(str[i]);

            }

            isNum = true;

        }else{

            isNum = false;

        }

    }

    return ret;

}

test('d567unt7jk80o9hkghftjs123ldka78sdassdfd653');
