Removed HTML element. What is the easiest way to get it back?

Question

In my main page I have a simple form. I have made it so I when the user clicks the "submit" button I send the form data to the server side and also just after submit I remove the form using Jquery. However, I would like to have a way so that when I click a button after geting the form removed it would appear again exactly as it was before geting removed.

When I click the form submit button I don't want the form to be invisible; I want the form to be removed from the page. Do I have to make a new form everytime I remove it to be exactly as the removed one or is there a way to get it back when clicking the "recovering" button?

Just in case, I am using JADE for rendering some other stuff... I am not sure if it is needed for this. Sorry for any mistakes, I am quite newbie in programming. I can give more information if needed.

Answer 1

You can use .is() to check if element is in document, .detach()

var div = $("div");
$("button").click(function() {
  if (div.is("button + div")) div.detach();
  else div.insertAfter(this)
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button>toggle div</button>
<div>abc</div>

Just hide the form when you submit, then show it when you want by clicking recover button :

$('#my-submit').on('click', function(e){
  e.preventDefault();
  
  $('#my-form').hide(); //Hide the form
})

$('#recover').on('click', function(){
  $('#my-form').show(); //Show the form
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="my-form">
  First name : <input name="f_name"/>
  <br>
  Last name : <input name="l_name"/>
  <br>
  <input type="submit" value='Submit' id="my-submit"/>
</form>
<br>
<button type="button" id='recover'>Recover</button>

Hope this helps.

Or you could also clone the form before submit using .clone(true) (The true indicating whether event handlers should be copied along with the elements. As of jQuery 1.4, element data will be copied as well) , then show it when user click on recuver button :

var my_form="";

$('#my-submit').on('click', function(e){
  e.preventDefault();
  
  my_form = $('#my-form').clone(true); //Save the form
  $('#my-form').remove();
})

$('#recover').on('click', function(){
  $('body').prepend(my_form); //Show the form
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="my-form">
  First name : <input name="f_name"/>
  <br>
  Last name : <input name="l_name"/>
  <br>
  <input type="submit" value='Submit' id="my-submit"/>
</form>
<br>
<button type="button" id='recover'>Recover</button>

Just save the element to a JS variable before removing the element, e. g.:

var form = document.getElementById('example-form');
form.parentNode.removeChild(form); // The form is removed.

Then you will be able to insert the element into document again, e. g.:

someElement.appendChild(form); // The form is restored.

It seems that you would like to show / hide particular element.

IMO, the toggle() would be the best option.

$('div').toggle();

If you want to remove it from DOM, you can use remove / detach as well.

$( "p" ).detach(); or $( "p" ).remove();

var p;
$('button').click(function(){
  if ( p ) {
    p.appendTo( "body" );
    p = null;
  } else {
    p = $( "p" ).remove();
  }
});

p
{
  color: red; 
}
