Is there a way to individually remove a selected radio button and its corresponding label?

Question

Is there a way to individually remove a selected radio button and its corresponding label?

Having trouble removing a selected radio button and its associated label. Struggling to implement the remove function that targets the selected radio button and removes both the button and label.

function removeRadioItem() {
  var radios = document.getElementsByName("attr_radio");
  for (var i = 0; i < radios.length; i++) {
    radio = radios[i];
    if (radio.checked) {
      radio.parentNode.removeChild(radio);
    }
  }
}

Answer №1

When using the addNewRadioItem function to add a new radio box, make sure to enclose it with either a span or div element (combining the radio button and label into one).

Similarly, in the removeRadioButton function, remove the enclosing element that contains the radio button and label.

function addNewRadioItem() {
  var htmlRadio = document.getElementById('radiopreview');
  var optionValue = document.getElementById('txtRadioValue');
  var optionDisplaytext = document.getElementById('txtRadioDisplayValue');

  if (optionValue.value == '') {
    alert('please enter option value');
    optionValue.focus();
    return false;
  }
  if (optionDisplaytext.value == '') {
    alert('please enter option display text');
    optionDisplaytext.focus();
    return false;
  }

  var radiobox = document.createElement("input");
  radiobox.type = 'radio';
  radiobox.value = optionDisplaytext.value;
  radiobox.id = optionValue.value;
  radiobox.name = 'attr_radio';

  var label = document.createElement('label')
  label.htmlFor = optionDisplaytext.value;

  var description = document.createTextNode(optionDisplaytext.value);
  label.appendChild(description);

  var radioDiv = document.createElement('span');
  radioDiv.appendChild(radiobox);
  radioDiv.appendChild(label);

  var container = document.getElementById('radiopreview');
  container.appendChild(radioDiv);

  alert("Option has been added successfully");
  optionValue.value = "";
  optionDisplaytext.value = "";

}

function removeRadioItem() {
  var radios = document.getElementsByName("attr_radio");
  for (var i = 0; i < radios.length; i++) {
    radio = radios[i];
    if (radio.checked) {
        var parentRadio = radio.parentNode;
      parentRadio.parentNode.removeChild(parentRadio);
    }
  }
}

<table border="0" align="float-left" id="radioForm">

    <td align="left">

The answer provided above is correct, but I have also implemented my own solution:

function createNewRadioButton() {
  var radioContainer = document.getElementById("radiopreview");
  var optionValue = document.getElementById("txtRadioValue");
  var optionDisplayText = document.getElementById("txtRadioDisplayValue");

  if (optionValue.value === "") {
    alert("Please enter an option value");
    optionValue.focus();
    return false;
  }
  if (optionDisplayText.value === "") {
    alert("Please enter an option display text");
    optionDisplayText.focus();
    return false;
  }

  var newRadio = document.createElement("input");
  newRadio.type = "radio";
  newRadio.value = optionDisplayText.value;
  newRadio.id = optionValue.value;
  newRadio.name = "attr_radio";

  var label = document.createElement("label");
  label.htmlFor = optionDisplayText.value;

  var description = document.createTextNode(optionDisplayText.value);
  label.appendChild(description);

  radioContainer.appendChild(newRadio);
  radioContainer.appendChild(label);

  alert("Option has been added successfully");
  optionValue.value = "";
  optionDisplayText.value = "";
}

function removeRadioButton() {
  var radioButtonList = document.getElementsByName("attr_radio");
  for (var i = 0; i < radioButtonList.length; i++) {
    let radioButton = radioButtonList[i];
    if (radioButton.checked) {
      let value = radioButton.value;
      radioButton.parentNode.removeChild(radioButton);
      let label = document.querySelector(`[for=${value}]`);
      label.parentNode.removeChild(label);
    }
  }
}

To remove the radio button along with its label, you can first remove the label that is the next sibling of the radio button and then remove the radio button itself

if (radio.checked) {
  radio.nextSibling.remove()
  radio.remove()
}

Check out this runnable example:

function addNewRadioItem() {
  var htmlRadio = document.getElementById('radiopreview');
  var optionValue = document.getElementById('txtRadioValue');
and so on...
...onClick="removeRadioItem();" /></td>
  </tr>

Answer №4

It's not ideal to directly manipulate the DOM like this, especially if you plan on transitioning to a framework like React in the future. It's best to avoid direct DOM manipulation.

My suggestion would be to keep track of all added radios in an array:

let radioArray = [];

Whenever a new radio is added, simply push it to the array:

let newRadio; // Define JSX or element with label for newRadio
radioArray.push(newRadio);

This way, you can easily access all radios in radioArray using methods like map or for-loop.

If you need to remove all radios, just clear the array:

radioArray = [];

You can also use Array.indexOf() to specifically remove a certain radio from the array.
