我在用户输入数据并提交后禁用输入字段。但是,如果我们刷新或按ctl + F5,禁用的字段将启用并变为可编辑状态。下面是我的代码,即使刷新,我该怎么做才能让它被禁用?谢谢。

<script type="text/javascript">
  document.getElementById('myButton').onclick = function() {
    document.getElementById('firstname').disabled = true;
    document.getElementById('lastname').disabled = true;
    document.getElementById('email').disabled = true;
  };
</script>

我使用localstorage来存储数据

最简单的解决方案是使用sessionStorage:

<script type="text/javascript">
  const disableInputs = function() {
    sessionStorage.disableInputs = 'true';
    document.getElementById('firstname').disabled = true;
    document.getElementById('lastname').disabled = true;
    document.getElementById('email').disabled = true;
  };
  if (sessionStorage.disableInputs === 'true') disableInputs();
  document.getElementById('myButton').onclick = disableInputs;
</script>

如果您希望禁用效果持续超过会话,请改用localStorage

使用sessionStorage:

    <script type="text/javascript">
      var disable = function() {
        document.getElementById('firstname').disabled = true;
        document.getElementById('lastname').disabled = true;
        document.getElementById('email').disabled = true;
        sessionStorage.setItem("isDisabled", true);
      };
    document.getElementById('myButton').onclick = disable;
    if(sessionStorage.getItem("isDisable") === 'true') {
      disable();//call your function
    }
    </script>

将设置置于

COOKIE版

function disablefield(){
        document.getElementById('firstname').disabled = true;
        document.getElementById('lastname').disabled = true;
        document.getElementById('email').disabled = true;
}
        document.getElementById('myButton').onclick = function() {

           $.cookie("is_disable", 1);
           disablefield();
        };

        if ($.cookie("is_disable")==1) disablefield();


      </script>

会话版

   function disablefield(){
            document.getElementById('firstname').disabled = true;
            document.getElementById('lastname').disabled = true;
            document.getElementById('email').disabled = true;
    }
            document.getElementById('myButton').onclick = function() {
               $.session.set("is_disable", "1");
               disablefield();
            };

            if ($.session.get("is_disable")==1) disablefield();


          </script>
