Question

我是javascript的新手并且可能尝试做一些愚蠢的事情，因为一小时的谷歌搜索没有导致任何例子。

我正在尝试学习对象，所以我创建了一个像这样的构造函数：

//generic object
function clip(name, xposition, firstVisibleFrame, lastVisibleFrame, playStart, playEnd, defaultFrame, seqLoopStart, seqLoopEnd, backStateLevel){
this.name = name;
this.xposition = xposition;
this.outlinesArray =[];
this.firstVisibleFrame = firstVisibleFrame;
this.lastVisibleFrame = lastVisibleFrame;
this.outlinePath = ("outlines/" +this.name +"_");
this.playStart = playStart;
this.playEnd = playEnd;
this.defaultFrame = defaultFrame;
this.seqLoopStart = seqLoopStart;
this.seqLoopEnd = seqLoopEnd;
this.backStateLevel = backStateLevel;
};

接下来，我将使用以下内容创建该对象的新实例：

livingroomTable = new clip("livingroomTable");

...但是现在我真的被卡住了因为我应该传递给函数的下一个参数实际上是一个包含数百个值的巨大数组..

我试着将数组放在参数中，如下所示：

 livingroomTable = new clip("livingroomTable", [value1, value2, value3, value4, value5 and so on and so on]);

但这给了我一个语法错误。

我也不想让这个数组成为全局变量。将值数组作为函数调用参数的一部分传递的正确语法是什么？

编辑：

以下是实际代码：

//generic object
function clip(name, xposition, firstVisibleFrame, lastVisibleFrame, playStart, playEnd, defaultFrame, seqLoopStart, seqLoopEnd, backStateLevel){
this.name = name; //objektin nimi tulee funktion kutsusta
this.xposition = xposition;
this.outlinesArray =[];
this.firstVisibleFrame = firstVisibleFrame;
this.lastVisibleFrame = lastVisibleFrame;
this.outlinePath = ("outlines/" +this.name +"_");
this.playStart = playStart;
this.playEnd = playEnd;
this.defaultFrame = defaultFrame;
this.seqLoopStart = seqLoopStart;
this.seqLoopEnd = seqLoopEnd;
this.backStateLevel = backStateLevel;
};


livingroomTable = new clip(
"livingroomTable", //name

//xposition

352, //firstVisibleFrame

545, //lastVisibleFrame

2058, //playStart

2304, //playEnd

2175, //defaultFrame

-1000, //seqLoopStart

-1000, //seqLoopEnd

1 //backStateLevel

);

实际上，我认为我的问题是阵列末尾的分号是对的吗？：d

Answer 1

您正在使用的原则没有任何问题。

您可以将数组放入变量中，并将其传递给函数：

theArray = [1,2,3,4,5];
livingroomTable = new clip("livingroomTable", theArray);

或者您可以直接在调用中使用数组文字：

livingroomTable = new clip("livingroomTable", [1,2,3,4,5]);

Answer 2

你得到一个 SyntaxError ，因为你在数组的末尾有一个;分号。

删除它，错误应该消失。

["1220.69","1220.69", ..., "-1048.08","-1048.08","-1048.08"];, // <-- right here

看起来应该是这样......

["1220.69","1220.69", ..., "-1048.08","-1048.08","-1048.08"], // <-- just a comma

您可能需要考虑使用代码验证程序，例如JSHint。

Answer 3

因此，构造函数不期望字符串和数组参数。你必须这样打电话：

livingroomTable = new clip("livingroomTable", value1, value2, value3, value4, ...);

将数组作为参数传递给对象
