读取只由字母数字组成的字符串中的数字，并组成数组

语言：JavaScript
//例如：输入 a133gv88a，输出 [133,88]

let line = readline();
let arr = line.split('');
let len = arr.length;
let out = [];
let tmpstr = '';
arr.forEach((el,index)=>{
    if(/\d+/.test(el)){
        tmpstr += el;
        if(index+1 == len&&tmpstr!='')
           out.push(tmpstr);
    }else{
        if(tmpstr!=''){
            out.push(tmpstr);
            tmpstr = '';
        }
    }
});
console.log(out);
