How to duplicate div by checking box?

Question

I want a user to be able to create an undetermined number of questions. Once a user has created one question I want another one (question 2) to appear and so on..

How would I go about this?

Thanks

Answer 1

you can try something like this

HTML

<div class="input-container">
  <input class="question" placeholder="Question" type="text"/>
</div>

<div class="add-option">+</div>

JS

//click the '+' sign
$(".add-option").click(function(){

   //find the first input and clone it then append it to the container
   $(".input-container input:first").clone().appendTo(".input-container");

   //clear any value from the next input had there been any added
   $(".input-container input:last").val("");
});

FIDDLE

UPDATE

I left out the part about the checkbox, from a UI perspective I don't think you need a checkbox to acomplish this, not sure it suggests "this is done and i want to move on" but that's up for you to decide. Here is a new fiddle

HTML

<div class="input-container">
  <input class="question" placeholder="Question" type="text"/>
</div>

<div class="add-option"><input type="checkbox"/></div>

JS

//click the checkbox
$(".add-option input[type=checkbox]").click(function(){

 //find the first input and clone it then append it to the container
 $(".input-container input:first").clone().appendTo(".input-container");

 //clear any value from the next input had there been any added
 $(".input-container input:last").val("");

 //reset the checkbox
 $(this).prop("checked", false);
});

NEW FIDDLE

Answer 2

I would do something like:

function addClone() {
    var cloned = document.getElementById('test').cloneNode(true); //clone the element
    document.body.appendChild(cloned); //add the cloned element to the page
}

<div id='test'>iadwjoam</div>
<input type="checkbox" id="xxx" name="xxx" onchange="addClone()" />

cloneNode() - https://developer.mozilla.org/en-US/docs/Web/API/Node.cloneNode

In javascript you can do like this

var i = 0;

function addMore() {
  i++;
  var parentDiv = document.createElement("div");

  var childLabel = document.createElement("label");
  childLabel.appendChild(document.createTextNode("Enter Value " + i));

  var childTextBox = document.createElement("input");
  childTextBox.type = "text";
  childTextBox.id = "txtInput" + i;

  var childCheckBox = document.createElement("input");
  childCheckBox.type = "checkbox";
  childCheckBox.onchange = addMore;

  parentDiv.appendChild(childLabel);
  parentDiv.appendChild(childTextBox);
  parentDiv.appendChild(childCheckBox);
  document.body.appendChild(parentDiv);

}

<div>
  Add Items
  <input type="checkbox" onchange="addMore()">
</div>

Hope this help

Here's more or less what I would do using pure JavaScript (see comments for explanation)

// Create a copy of a blank Question node
question_template = document.getElementById("questions").firstElementChild.cloneNode(true);
// A nice cloning wrapper
new_question = function(){return question_template.cloneNode(true);};
// Something to do when the user is finished putting in questions
alrt = function(){
    alert(Array.prototype.map.call(document.getElementById(
      "questions").getElementsByTagName("input"),
      function(elt){return elt.value;}));
};
// Hook for when text is placed in textbox
addnew = function(){
    // Remove the event listener (If you don't do this, then on every
    //   keystroke a new box will be created
    document.getElementById("questions").lastElementChild.oninput = function(event){};
    // Add a new line
    document.getElementById("questions").appendChild(document.createElement("br"));
    // Add a new question box
    document.getElementById("questions").appendChild(new_question());
};

<div id="questions">
<input type="text" oninput="addnew()"/>
</div>
<input type="button" value="Done" onclick="alrt()"/>

UPDATE: I just saw your elaboration in the main post's comment section. You could implement that with something like this:

// Create a copy of a blank Question node
question_template = document.getElementById("questions").firstElementChild.cloneNode(true);
// A nice cloning wrapper
new_question = function(){return question_template.cloneNode(true);};
// Something to do when the user is finished putting in questions
alrt = function(){
    alert(Array.prototype.map.call(document.getElementById(
      "questions").getElementsByTagName("input"),
      function(elt){return elt.value;}));
};
// Hook for when text is placed in textbox
addnew = function(){
    // Add a new line
    document.getElementById("questions").appendChild(document.createElement("br"));
    // Add a new question box
    document.getElementById("questions").appendChild(new_question());
};

<div id="questions">
    <input type="text"/>
    </div>
<input type="button" value="Add Another" onclick="addnew()"/>
    <input type="button" value="Done" onclick="alrt()"/>

This can be implemented with most any input element with the right events. The W3 Schools has a nice reference, if you need it.
