如何根据点击的元素在javascript中设置告警内容？

var button = document.getElementById("myButton");
button.addEventListener("click", function() {
  // 在这里设置告警内容的逻辑
});

var button = document.getElementById("myButton");
button.addEventListener("click", function() {
  var alertContent = "这是一个告警内容";
  alert(alertContent);
});

var button1 = document.getElementById("button1");
var button2 = document.getElementById("button2");

button1.addEventListener("click", function() {
  var alertContent = "这是按钮1的告警内容";
  alert(alertContent);
});

button2.addEventListener("click", function() {
  var alertContent = "这是按钮2的告警内容";
  alert(alertContent);
});
