How to dynamically create and remove div's with inputs with jquery

Question:

I need to dynamically create and remove div´s for a form I have, I've done it using a table, but now I was asked for div´s . I tried to make an adaptation but I couldn't, what I need is to create a button to insert the div´s and one to remove them if necessary.

My complete form was:

<section>
   <div class="container">
      <div class="container">
         <div class="row">
            <header class="text-center margin-top-20">

            <br>                    
            <header class="text-center margin-top-20">

I have several rows in this form, but the one I need to insert the most is this one:

<div class="row">
 <div class="col-md-4 col-sm-4">
    <input type="text" name="BancoAutorizado" id="BancoAutorizado" value="" class="form-control required" tabindex="2" placeholder="Banco">
    <i class="fancy-arrow"></i> 
 </div>
 <div class="col-md-4 col-sm-4">
    <input type="text" name="AgenciaAutorizado" id="AgenciaAutorizado" value="" class="form-control required" tabindex="2" placeholder="Agência">
    <i class="fancy-arrow"></i> 
 </div>
 <div class="col-md-4 col-sm-4">
    <input type="text" name="CCAutorizado" id="CCAutorizado" value="" class="form-control required" tabindex="2" placeholder="Conta Corrente">
    <i class="fancy-arrow"></i> 
 </div>
</div>

My form has this ID:

<form id="frmCadastro" class="sky-form clearfix" action="" method="post" target="_blank">

I won't post what I tried to do because honestly it won't be of any use.

Answer:

I suggest you create a div to .row you want to add. Why? Because it will make adding the new .row . As they are loose in the middle of the <form> , it would be too complicated to add the new ones.

I created a div with id="dadosbanco" and put the two .row inside it. This way we will have this div as a reference and the work becomes extremely simple.

I created an Add button to add the new .row and a Remove button on each line to remove the respective line. I also put a code in the function that prevents all lines from being removed, and at least one must remain.

See the example below that you should adapt to your Bootstrap:

var cloneform = $('#dadosbanco').html();
$(document).on('click','.remDiv, .addDiv', function(e){
   var thisClass = Array.from(e.target.classList);
   ~thisClass.indexOf('remDiv')
      ?
      ($('.remDiv').length > 1
         ?
         $(this).closest('.row').prev().add($(this).closest('.row')).remove()
         :
         0)
      :
      $('#dadosbanco').append(cloneform);
});

GRADES

  • Added [] to field names to be sent in array form.
  • Regarding the id 's of the fields, if they are not to be used, I suggest you remove them, because when you create a new line, the id 's will be repeated and this will cause problems if you are using them. I suggest instead of id 's use classes.
