如何在jQuery中实现“类似撤销”的翻译功能

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

<input type="text" id="inputText">
<button id="translateButton">翻译</button>

$(document).ready(function() {
  $("#translateButton").click(function() {
    var inputText = $("#inputText").val();
    $.ajax({
      url: "翻译接口地址",
      method: "POST",
      data: { text: inputText },
      success: function(response) {
        // 处理翻译结果
      },
      error: function() {
        // 处理错误
      }
    });
  });
});

success: function(response) {
  $("#translationResult").text(response.translation);
},

<button id="undoButton">撤销</button>

var previousTranslation = ""; // 保存上一次的翻译结果

$(document).ready(function() {
  $("#translateButton").click(function() {
    var inputText = $("#inputText").val();
    $.ajax({
      url: "翻译接口地址",
      method: "POST",
      data: { text: inputText },
      success: function(response) {
        $("#translationResult").text(response.translation);
        previousTranslation = response.translation;
      },
      error: function() {
        // 处理错误
      }
    });
  });

  $("#undoButton").click(function() {
    $("#translationResult").text(previousTranslation);
  });
});
