HTML：如何在html中每次点击标签时刷新page/document？

Question

我准备了一个带有标签的 html 页面。每个选项卡都有输入字段。下面是 html 代码。

<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
body {font-family: Arial;}

/* Style the tab */
.tab {
  overflow: hidden;
  border: 1px solid #ccc;
  background-color: #f1f1f1;
}

/* Style the buttons inside the tab */
.tab button {
  background-color: inherit;
  float: left;
  border: none;
  outline: none;
  cursor: pointer;
  padding: 14px 16px;
  transition: 0.3s;
  font-size: 17px;
}

/* Change background color of buttons on hover */
.tab button:hover {
  background-color: #ddd;
}

/* Create an active/current tablink class */
.tab button.active {
  background-color: #ccc;
}

/* Style the tab content */
.tabcontent {
  display: none;
  padding: 6px 12px;
  border: 1px solid #ccc;
  border-top: none;
}
</style>
</head>
<body>



<div class="tab">
  <button class="tablinks" onclick="openTab(event, 'One')" id="defaultOpen">One</button>
  <button class="tablinks" onclick="openTab(event, 'Two')">Two</button>
  <button class="tablinks" onclick="openTab(event, 'Three')">Three</button>
</div>

<div id="One" class="tabcontent">
  <h3>One</h3>
  One :
<input type="number" min="0.0"   id="txtOne"  autofocus="autofocus"  />
</div>

<div id="Two" class="tabcontent">
  <h3>Two</h3>
 Two :
<input type="number" min="0.0"   id="txtTwo"  autofocus="autofocus"  />
</div>

<div id="Three" class="tabcontent">
  <h3>Three</h3>
  Three : 
<input type="number" min="0.0"   id="txtThree"  autofocus="autofocus"  />
</div>

<script>
function openTab(evt, Name) {
  var i, tabcontent, tablinks;
  tabcontent = document.getElementsByClassName("tabcontent");
  for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].style.display = "none";
  }
  tablinks = document.getElementsByClassName("tablinks");
  for (i = 0; i < tablinks.length; i++) {
    tablinks[i].className = tablinks[i].className.replace(" active", "");
  }
  document.getElementById(Name).style.display = "block";
  evt.currentTarget.className += " active";
  document.getElementById("txtOne").focus();
document.getElementById("txtTwo").focus();
document.getElementById("txtThree").focus();

}

// Get the element with id="defaultOpen" and click on it
document.getElementById("defaultOpen").click();

</script>

</body>
</html>

我第一次单击每个选项卡并在输入字段中输入了一些值。第二次单击每个选项卡时，输入字段已输入 values.Now 我想清除输入字段或 reload/refresh 页面，同时进一步单击选项卡并希望设置自动聚焦输入字段.指导我的情况。提前致谢。

Answer 1

尝试重置值

function reset(Name) {
  document.getElementById("txt"+Name).value = '';
}

function openTab(evt, Name) {
  reset(Name);
  // your code
}
