ANCC h5 Object doesn't support property or method 'gotoAndStop'

[chenjil43641795]

I want to make a key to control the movie clip's function.

But not running properly.

this.stop()
js = 0

window.addEventListener("keydown", lr, false);
function lr(e)
{
switch(e.keyCode)
{
  case 37:

   js = js -1

   name = "exportRoot.a" + js

   alert(name)

   name.gotoAndStop(2)

   break;

  case 39:
   js = js + 1
   name = "exportRoot.a" + js
   //alert(name)
   name.gotoAndStop(2)
   break;
}
}

Hint is  Object doesn't support property or method 'gotoAndStop'

Of course name doesn't support gotoAndStop; name is a string, not an object reference. If you want a variable reference to an object, you have to use bracket notation.

js++;

name = "a" + js;

exportRoot[name].gotoAndStop(2);

Or just...

exportRoot["a" + ++js].gotoAndStop(2);

By the way, I really hope you're declaring name somewhere as a var because otherwise you're making it a global variable. That's bad.

And you're missing semicolons at the end of all your lines of code.

I'm sorry.

I checked the system.

I found out there was something wrong with my browser before the code went wrong.

My problem is that all the code is a hint

"Object doesn't support property or method "

Even if I only write 1 alerts ("1").

Found that there was a conflict between a software.

Uninstall the software, it's all right now.

About your help, thank you.

Calling variables across scopes, I'm not very skilled.

Writing habits and symbols, do have a problem, will pay attention to.

I've been doing this for 1 days.

The code still can't run after the software conflict problem is resolved

I finally found out the problem.

I'm so stupid.

Should have noticed that HTML5 started at 0.

Jump to frame 2nd is actually jump to frame 3rd

Modified into gotoAndStop (1);

It's going to run smoothly now.

Thank you for your help.

this.stop()

window.addEventListener("keydown", lr, false);

var js = 0;

function lr(e)

{

switch(e.keyCode)

{

  case 37:

   exportRoot["a" + js--].gotoAndStop(0);

   break;

  case 39:

   exportRoot["a" + ++js].gotoAndStop(1);

   break;

}

}
