html文件Js写输入框和弹框调接口jQuery

发布时间：2023年12月30日

?业务场景：需要使用写一个html文件，实现输入数字，保存调接口。

1、使用 JS原生写法，?fetchAPI调接口，使用 alert 方法弹框会阻塞线程，所以写了一个弹框。

      <div class="tip-content">提示内容</div>

    </div>
  </div>
  <script>
    let url = 'http://1x.1x.6.1xxx:12xxx';
    let api = '/base/xxxxxDXZZConfig';

    function handleInputChange(event) {
      event.target.value = Number(event.target.value).toFixed(2);
    }

    function handlekeyDown(event) {
      console.log(event);

        showTip('请输入有效的数值');
        return;
      }

      let data = { value };
      // 使用 URLSearchParams 将数据对象转换为查询字符串
      let params = new URLSearchParams(data).toString();
      let requestUrl = `${url}${api}?${params}`;
      let options = { method: "GET" }

      try {
        fetch(requestUrl, options)
          .then(res => res.json())
          .then(json => {

    function showTip(message) {
      tipBox.querySelector('.tip-content').innerHTML = message;
      tipBox.style.display = 'block';
    }

    function hideTip() {
      tipBox.style.animation = 'tip-hide .3s forwards';
      setTimeout(function () {
        tipBox.style.display = 'none';
        tipBox.style.animation = '';
      }, 300);
    }

  </script>
</body>

</html>

?2、使用jQuery，先 npm install jquery，然后引入
