ANCC HTML5 .How to make a click event execute only 1 times

[chenjil43641795]

I use the code below to manipulate.

Use gotoAndStop to jump to this frame,

will be again "var kg = True"

Causes the button to click again.

Is there any other way to make the button perform only 1 times?

var kg = true

this.on("click", pd);
function pd()
{

if(kg)
{
  this.play();
  kg = false
}

}
this.stop();

[kglad]

among the ways to do this:

var alreadyExecuted;

if(!alreadyExecuted){

alreadyExecuted=true;

var pdF=pd.bind(this);

this.addEventListener('click',pdF);

}

function pd(){

this.removeEventListener('click',pdF);

this.play();

}

The code is still invalid,

When the movie loops and then jumps to the start, the button can be executed again, unable to implement 1 times.

Just use on with the "once" flag set.

https://createjs.com/docs/easeljs/classes/EventDispatcher.html#method_on

this.on("click", this.play, this, true);

And DON'T let your movie loop to the start.

Everyone's methods have been tried,

When you jump to this frame, it will count again.

Sometimes  for this kind of problem I use a variable like

var active = 1;

if(active ==1){

// do something

active = 0;

}

This way since your variable has been set to 0 the action will not repeat since it is not reset to 1 if that makes sense.

[chenjil43641795]

If you jump to this frame again.

Active will be equal to 1 again.

It caused the failure.

If you write to the global function directly then there is no problem.( active = 1;Do not use Var)

I want to know the way to not use global functions.

Then do not go back to the initial frame. I put most of my code on frame 1 and then control everything from there. I have been totally successful controlling plays exactly as I want especially when I want something to happen only once.

[chenjil43641795]

Because special needs must jump to the code frame.

Fortunately, it is. Kglad's answer was implemented only once

[kglad · Accepted solution]

use:

if(!this.alreadyExecuted){

this.alreadyExecuted=true;

var pdF=pd.bind(this);

this.addEventListener('click',pdF);

}

function pd(){

this.removeEventListener('click',pdF);

this.play();

}
