Dynamically add and remove <input> jQuery

Add a remove link to delete the lastly added element. Refer the below link

http://jsfiddle.net/sqn9Y/4/

$("#remove").click(function(e){
if($('#teamArea input').length>1) {//remove all except one
     $('#teamArea input:last').remove();
}
});

check the below fiddle

http://jsfiddle.net/sqn9Y/3/

$("#addRemoveTeam").click(function(e) {

   e.preventDefault();
   var newField = $('#tag_' + tagCount);
   tagCount--;
  newField.remove();
});

This would remove the last one.Similarly if u want to remove all the inputs just run it in a loop.Hope this helps. enter code here This would remove the last one.Similarly if u want to remove all the inputs just run it in a loop.Hope this helps.

<div class="control-group">
<div id="teamArea"class="controls">
<input type="text" name="teamName[]">
<input type="text" name="teamName[]">
</div>
<a id="addNewTeam">Add another</a>
<a id="removeNewTeam">Add another</a>
</div>

$("#addNewTeam").click(function(e) {
//Append new field
e.preventDefault();
var newField = $('#teamArea input:first').clone();
newField.val("");
$("#teamArea").append(newField);
});
$("#removeNewTeam").click(function(e) {
var currentChildren=$("#teamArea").children();
var currentChidlrenLength=currentChildren.length;
$("#teamArea").children()[currentChidlrenLength-1].remove()
});

There are a few things I'm not clear on about what you want. Do you want the remove button at the bottom with the add button? Do you want only one remove button for all newly added input fields?

Assuming the answer to both of those questions is 'yes' AND that you want the remove button to remove the inputs in the reverse order they were added, the simplest idea I can think of is to hide/show the remove button.

The example code (including your code) would be:

HTML

 <div class="control-group">
    <div id="teamArea"class="controls">
      <input type="text" name="teamName[]">
      <input type="text" name="teamName[]">
    </div>
   <a id="addNewTeam">Add another</a>
   <a id="removeLastTeam" style="display:none;">Remove Last</a>

JavaScript

$("#addNewTeam").click(function(e) {
    //Append new field
    e.preventDefault();
    var newField = $('#teamArea input:first').clone();
    newField.val("");
    $("#teamArea").append(newField);
  });

$('#removeLastTeam').click(function() {
    if ($('div.controls').find('input').length > 2)
    {
        $("#teamArea input:last-child").remove();
    }
});

$('.control-group').click(function(e) {

    if ($('div.controls').find('input').length > 2)
    {
        $('#removeLastTeam').show();
    }
});

 </div>

I'd like to expand on Kevins awesomely succinct example above, say for instance that you wanted to limit the amount of input fields a user could add. You can add a simple counter to help you achieve your goal.

In my example, I was building a form that would allow users to add multiple input names if they had more than one dog.

    var counter = 0
    jQuery(function () {
      $(".newDog").click(function(){
        counter ++;
        if (counter < 4) {
          var elem = $("<input/>",{
            type: "text",
            name: `dogname${counter}`
        });
        } else {
          alert("You can only add 4 Dog Names")
        }
        
        var removeLink = $("<span/>").html("X").click(function(){
            $(elem).remove();
            $(this).remove();
            counter --;
        });
        
        $(".dogname-inputs").append(elem).append(removeLink);
    });
    })
