有些AS3函数处理通过允许使用约定的参数任意数量的超载
公共职能DoSomething的(...休息):无效;
我是在一个情况下,我需要一个数组(任意长度)的所有值传递到这种类型的函数......我不知道如何做到这一点。建议?
下面是一个黑客攻击的解决方案,但它是不可扩展的:
开关(args.length){
情况下0:DoSomething的();打破;
案例1:DoSomething的(参数[0]);打破;
案例2:DoSomething的(参数[0],的args [1]);打破;}
解决方案
查看Function#Apply().它可以让你通过参数数组。
doSomething.apply(contextObj,参数);
Some as3 functions handle overloading by allowing for an arbitrary number of parameters using the convention:
public function doSomething( ... rest ):void;
I am in a situation where I need to pass all the values of an array (of arbitrary length) into this type of function... I am not sure how to do this. Suggestions?
Here is a hack solution, but it is not extensible:
switch (args.length) {
case 0: doSomething(); break;
case 1: doSomething(args[0]); break;
case 2: doSomething(args[0], args[1]); break;}
解决方案
Check out Function#Apply(). It lets you pass the parameters as an array.
doSomething.apply(contextObj, args);
