Remove dynamically created elements in a form

Question

I know this is a basic questions, but I am working on making a dynamic form and was having a bit of trouble figuring out how to delete elements that share the same class. I have looked around on the web and other posts for a means to accomplish this, but still was unable to figure it out.

I am new to this so I apologize for the basic question. Below, I have pasted the relevant code and my attempt at this. Would anyone be able to assist me?

var ingCounter = 1;
var dirCounter = 1;
var limit = 10;

function addIngredient(divName){
    if (ingCounter == limit)  {
          alert("You have reached the add limit");
    }
    else {
          var newdiv = document.createElement('div');
          newdiv.innerHTML = "<div class='ingredientSet'><input class='ingredientInput' type='text' name='ingredients[]'><button class='deleteIngredientButton' type='button' onClick='removeElement('directionSet');'>X</button></div>";
          document.getElementById(divName).appendChild(newdiv);
          ingCounter++;
    }
}

function addDirection(divName){
    if (dirCounter == limit)  {
          alert("You have reached the add limit");
    }
    else {
          var newdiv = document.createElement('div');
          newdiv.innerHTML = "<div class='directionSet'><input class='directionInput' type='text' name='directions[]'><button class='deleteDirectionButton' type='button'>X</button></div>";
          document.getElementById(divName).appendChild(newdiv);
          dirCounter++;
    }
}

function removeElement(elementId) {
    // Removes an element from the document
    var element = document.getElementById(elementId);
    element.parentNode.removeChild(element);
}

Thanks for any help.

In your code you are using getElementById but there is no id called directionSet its a class.

You can simply use parentElement and remove to remove the newly added dynamic inputs by calling an onClick function.

In the onClick function removeElement() - this refers to the elements we have clicked and it will remove from the form.

 var ingCounter = 1; var dirCounter = 1; var limit = 10; function addIngredient(divName) { if (ingCounter == limit) { alert("You have reached the add limit"); } else { var newdiv = document.createElement('div'); newdiv.innerHTML = "<div class='ingredientSet'><input class='ingredientInput' type='text' name='ingredients[]'><button class='deleteIngredientButton' type='button' onClick='removeElement(this);'>X</button></div>"; document.getElementById(divName).appendChild(newdiv); ingCounter++; } } function addDirection(divName) { if (dirCounter == limit) { alert("You have reached the add limit"); } else { var newdiv = document.createElement('div'); newdiv.innerHTML = "<div class='directionSet'><input class='directionInput' type='text' name='directions[]'><button class='deleteDirectionButton' onClick='removeElement(this);' type='button'>X</button></div>"; document.getElementById(divName).appendChild(newdiv); dirCounter++; } } function removeElement(elementId) { // Removes an element from the document elementId.parentElement.remove() }
