Javascript之【函数回调】

1. 以函数为回调参数(建议使用)var callbackParam = {test:"callbackParam"};asysc( asyscCallback, callbackParam);//回

1. 以函数为回调参数(建议使用)

var callbackParam = {test:"callbackParam"};asysc( asyscCallback, callbackParam);//回调函数function asyscCallback(data, callbackParam){    console.info("called asysc successfully");}/** * callback 回调函数 * paramObj 回调参数 */function asysc(callbackFunc, callbackParam){    var data = {data:"data"};    callbackFunc.apply(this, [data, callbackParam]);    //callbackFunc(data, callbackParam);}

2.以函数名(字符串)为回调参数

需要用到Function：var func = new Function('param1', 'param2',...,'paramN', 'funcBody');

var callbackParam = {test:"callbackParam"};asysc( "asyscCallback", callbackParam);//回调函数function asyscCallback(data, callbackParam){    console.info("called asysc successfully");}/** * callback 回调函数 * paramObj 回调参数 */function asysc(callbackFunc, callbackParam){    var data = {data:"data"};    var strFuncName = "return " + callbackFunc + "(data, callbackParam)";    func = new Function('data', 'callbackParam', strFuncName);    func(data, callbackParam);}
