标签:ascii码 返回值 string int 应该 alert script func rip
var map = Array.prototype.map var a = map.call("Hello World",function(x){ return x.charCodeAt(0); })
// a的值为[72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100]
// 字符转ascii码:用charCodeAt();
// ascii码转字符:用fromCharCode();
function returnInt(e){ return parseInt(e,10); } ["1","2","3"].map(returnInt); // 此时会返回[1,2,3]
