How to write tabbed form in html

2k Views Asked by Agnar Renolen At 25 May 2020 at 21:37

Referring to this example on how to create a tabbed form in html: the example works as expected until you embed the code within a <form> element. Then clicking the tabs causes a form submission, and in the case of the example, an error.

Does anyone know a way out of this?

In the example you submit section there is a function called OpenCity that passes a event. To stop it from refreshing or submitting you just have to prevent the default state:

<script>
function openCity(evt, cityName) {

   evt.preventDefault();

   ...
}
</script>

function openCity(evt, cityName) {
 
    evt.preventDefault();

  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(cityName).style.display = "block";
  evt.currentTarget.className += " active";
}

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;
}

.button {
  padding:15px;
  border: none 0px white;
  border-color: white;
  background-color: #318DE8;
  border-radius: 3px;
  color: white;
}
