string String.prototype.format(params object[])
实现这个方法,是因为我太习惯cSharp里的String.Format方法。这个自然没有它功能强大,仅仅实现按照参数和格式序号简单替换。
String.prototype.format = function(){ if(arguments.length == 0) return this; var _this = this, i = 0, matches = _this.match(/{\d+}/g), l = Math.min(arguments.length, matches.length), _i, _s; if(matches.length == 0){ _this = null; i = null; matches = null; l = null; _i = null; _s = null; return this; } for(; i < l; i++) if(!isNaN(_i = parseInt((_s = matches[i] + '').substr(1)))) _this = _this.replace(_s, arguments[_i] + ''); i = null; matches = null; l = null; _i = null; _s = null; return _this; }
