我有名为 1,2 和 3 的按钮。下面是 a、b、c、d 按钮。当我单击第一个按钮并单击“A”按钮时，我收到 (Test Test2) 警告。但我无法单击第二个按钮并单击“A”按钮。我想再发出一个警告。例如：我单击第一个按钮，然后单击 A 按钮，如屏幕上显示的 (Test Test6)，但我不能。谢谢。

var firstButtonPressed = false;
function onFirstButtonClick() {
  firstButtonPressed = true;
}

function onfourButtonClick() {
  if(firstButtonPressed) {
    alert('Test Test2');
    firstButtonPressed = false;
  } else {
    alert('Test2');
  }
  return;
}


var secondButtonPressed = false;
function onSecondButtonClick(){
  secondButtonPressed = true;
}

function onFourButtonClick(){
  if(secondButtonPressed){
    alert('Button2 Test');
    secondButtonPressed = false;
  }else {
    alert ('61 Tes-t')
  }
}
