在django表单HTML中将`a‘标记与` `href`’链接

Question

我有一个django表单，我试图创建一个向上的表单，当您完成一个部分时，在同一个HTML模板中单击go下一节的旁边：

我已经创造了一切都很好，但我被卡住按钮的下一个按钮。我已经设置了一个id并将其链接到一个href，但没有按要求打开下一个表单。

以下是我试图让它更容易解释的东西：

          <ul class="nav nav-pills mb-3" id="ex-3" role="tablist">
            <!-- General Information -->
            <li class="nav-item" role="presentation">
              <a class="nav-link active" id="ex-3-tab-1" data-mdb-toggle="pill"
                href="#generalInformation"
                role="tab" aria-controls="pills-1" aria-selected="true"
                >General Information</a>
            </li>
            <!-- Contact Information -->
            <li class="nav-item" role="presentation">
              <a
                class="nav-link"
                id="tab_contactInformation"
                data-mdb-toggle="pill"
                href="#contactInformation"
                role="tab" aria-controls="pills-2" aria-selected="false"
                >Contact Information</a
              >
            </li>
        </ul>

在一般信息部分中，我添加了一个a标记来链接到href="#contactInformation"，与顶部显示的导航药片相同，但它并没有导致这一点。只是在同一个地方说。

                    <a
                      href="#contactInformation"
                      >Contact Information</a
                    >

我的问题

如何添加a标记，并将href链接到下一部分？我做错了什么，我该如何解决呢？谢谢你事先的解释，让我明白。

Answer 1

如果我没有错，当你点击'a‘标签时，你想移动到另一个部分。您可以尝试创建一个div标记，其中“id”作为“contactInformation”，作为hashtag，如果我没记错的话，可以链接到“id”值。因此，如果要保持#contactInformation，您将需要一个id='contactInformation‘的div标记。

我想你说的是多步形式:-

​

var currentTab = 0; // Current tab is set to be the first tab (0)
showTab(currentTab); // Display the current tab

function showTab(n) {
  // This function will display the specified tab of the form...
  var x = document.getElementsByClassName("tab");
  x[n].style.display = "block";
  //... and fix the Previous/Next buttons:
  if (n == 0) {
    document.getElementById("prevBtn").style.display = "none";
  } else {
    document.getElementById("prevBtn").style.display = "inline";
  }
  if (n == (x.length - 1)) {
    document.getElementById("nextBtn").innerHTML = "Submit";
  } else {
    document.getElementById("nextBtn").innerHTML = "Next";
  }
  //... and run a function that will display the correct step indicator:
  fixStepIndicator(n)
}

function nextPrev(n) {
  // This function will figure out which tab to display
  var x = document.getElementsByClassName("tab");
  // Exit the function if any field in the current tab is invalid:
  if (n == 1 && !validateForm()) return false;
  // Hide the current tab:
  x[currentTab].style.display = "none";
  // Increase or decrease the current tab by 1:
  currentTab = currentTab + n;
  // if you have reached the end of the form...
  if (currentTab >= x.length) {
    // ... the form gets submitted:
    document.getElementById("regForm").submit();
    return false;
  }
  // Otherwise, display the correct tab:
  showTab(currentTab);
}

function validateForm() {
  // This function deals with validation of the form fields
  var x, y, i, valid = true;
  x = document.getElementsByClassName("tab");
  y = x[currentTab].getElementsByTagName("input");
  // A loop that checks every input field in the current tab:
  for (i = 0; i < y.length; i++) {
    // If a field is empty...
    if (y[i].value == "") {
      // add an "invalid" class to the field:
      y[i].className += " invalid";
      // and set the current valid status to false
      valid = false;
    }
  }
  // If the valid status is true, mark the step as finished and valid:
  if (valid) {
    document.getElementsByClassName("step")[currentTab].className += " finish";
  }
  return valid; // return the valid status
}

function fixStepIndicator(n) {
  // This function removes the "active" class of all steps...
  var i, x = document.getElementsByClassName("step");
  for (i = 0; i < x.length; i++) {
    x[i].className = x[i].className.replace(" active", "");
  }
  //... and adds the "active" class on the current step:
  x[n].className += " active";
}

您必须首先创建节并为节提供id。

如果您单击“联系人节”，它会将yo放入联系人部分，您可以在这里使用is作为菜单和菜单部分，代码如下：

<a href="#contact">Contact Section</a>

<section id="contact">

<h5>Address</h5>
<h5>Phone</h5>
<p>some text</p>

</section>
