雨夜带刀

最近在看司徒正美的ajax框架代码的时候发现一段有意思的代码：

"get post".replace( dom.rword, function(method){
	dom[ method ] = function( url, data, callback, type ) {
		if ( dom.isFunction(data) ) {
			type = type || callback;
			callback = data;
			data = undefined;
		}
		return dom.ajax({
			type: method,
			url: url,
			data: data,
			success: callback,
			dataType: type
		});
	};
});
