在javascript中动态推送即将到来的id和value

document.getElementById("myInput").addEventListener("input", function(event) {
  var id = event.target.id;
  var value = event.target.value;
  // 进行相应的处理
});

var previousId = "";
var previousValue = "";

setInterval(function() {
  var element = document.getElementById("myInput");
  var id = element.id;
  var value = element.value;
  
  if (id !== previousId || value !== previousValue) {
    // 进行相应的处理
    previousId = id;
    previousValue = value;
  }
}, 1000); // 每隔1秒检查一次

var observer = new MutationObserver(function(mutationsList) {
  for (var mutation of mutationsList) {
    if (mutation.type === "attributes" && (mutation.attributeName === "id" || mutation.attributeName === "value")) {
      var id = mutation.target.id;
      var value = mutation.target.value;
      // 进行相应的处理
    }
  }
});

var element = document.getElementById("myInput");
observer.observe(element, { attributes: true });
