[英]I can't call a function created inside another function using Node.JS
[英]How can i call a function, whose name is dynamically created by combining some variables in node.js?
我在Node.js中有一個構造函數
function Response() {
var numberOfArguments = arguments.length;
var getArguments = arguments;
var newConstructor = arguments.callee.name + i; // ie, (Constructor Name + numberOfArguments)
/* Here i want to call the constructor with the value in newConstructor and pass the arguments in getArguments*/
// ie, call function like Response0();
// Response1(getArguments[0]);
}
function Response0() {
//Constructor Body for Response0()
}
function Response1(sid) {
//Constructor Body for Response0()
}
現在我的問題是我該如何調用這些函數Response0()或Response1(),具體取決於進入Response構造函數的參數數量。
我沒有嘗試過,但是也許這是一種方法:
Response0() {
//Constructor Body for Response0()
}
Response1(sid) {
//Constructor Body for Response0()
//NOTE: sid will be an array of length 1
}
//here we create kind of a lookup table that binds constructors to a specific number of arguments
var dictionary = {
0 : Response0,
1 : Response1
};
Response() {
var args = Array.prototype.slice.call(arguments),
numberOfArguments = args.length;
if (dictionary.hasOwnProperty(numberOfArguments) {
//here we call the constructor and give an array of the current args to work with
new dictionary[numberOfArguments](args);
}
}
