Pixi.js:onclick change Texture

[Ollie]

Hello,
I want to judge which PNG should be displayed in the click event,
How can I modify it?

var aTexture =new PIXI .Texture.from("A.png" );

var bTexture =new PIXI .Texture.from("B.png”);

var testBtn = new PIXI.Sprite(aTexture);

testBtn.on('click', (event) => {

if（true）{

testBtn.PIXI.Sprite(aTexture);

}

else{

testBtn.PIXI.Sprite(bTexture);

}

})

app.stage.addChild(testBtn);

TKS。
