Passing an array to an object as an argument

Question

I'm new to javascript and probably trying to do something stupid since an hour of googling didn't result in any examples.

I'm trying to learn objects so I made a constructor function like this:

//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;
};

Next I will create a new instance of that object with something like:

livingroomTable = new clip("livingroomTable");

...but now I'm really stuck because the next parameter I should pass to the function is actually a huge array with hundreds of values..

I tried to put the array inside the argument like this:

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

but this gives me a syntax error.

I don't want to make this array a global variable either. What is the correct syntax of passing an array of values as a part of the function call's arguments?

EDIT:

Here is the actual code:

//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

352, //firstVisibleFrame

2058, //playStart

2304, //playEnd

2175, //defaultFrame

-1000, //seqLoopStart

-1000, //seqLoopEnd

1 //backStateLevel

);

Hmmmm actually I think my problem is the semicolon at the end of array right? :D

If you're getting a SyntaxError, you'll need to show your actual code to get help. — user1106925

You might want to consider passing JSON to the constructor, it's nicer. — Csongor Fagyal

You're getting a SyntaxError because you have a ; semicolon at the end of the Array.

Remove that, and the error should go away.

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

It should look like this...

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

You may want to consider using a code validator like JSHint.

There is nothing wrong with the principle that you are using.

You can put the array in a variable, and pass that to the function:

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

Or you can use an array literal directly in the call:

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

Thanks for the assurance! I noticed my syntax error was caused by the semicolon (and earlier by and extra comma) :S Sorry for this!

So, your constructor don't expect string and array parameters. You must call like that:

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