#1 Created at ... [Delete] [Delete and Lock User]

function string2int(s) { 
return s==='0'?0:s.split("").reduce(function(x,y){
         return x*10+(y-0);
    });  
}

#2 Created at ... [Delete] [Delete and Lock User]

附上我的代码：

function string2int(s) {
  return s.split("").map(Number).reduce(function(x, y) {
    return x * 10 + y;
  });
}
