how to add and remove div using jquery

Question

I'm making a scenario where user will be able to add a new row with "Remove" option by clicking "Add" button. If they click "Remove" button, the entire row will be deleted. I've put script for it. But, it's not working perfectly. Kindly, take a look on my fiddle: http://jsfiddle.net/learner73/gS8u2/

My problem is:

(1) If user click "Add" button, a new row will be added. That's good. But, it's gone below the "Add" button. I want, the new row will be added above the "Add" button, I mean "Add" button should be always at the bottom.

(2) At my code, if user click "Remove" button on the previously created row, the entire row will be deleted. That's good. But, when they click "Remove" button on dynamically created row, nothing will happened!

HTML:

<div class="optionBox">
    <div class="block">
        <input type="text" /> <span class="remove">Remove Option</span>
    </div>
    <div class="block">
        <input type="text" /> <span class="remove">Remove Option</span>
    </div>
    <div class="block">
        <span class="add">Add Option</span>
    </div>
</div>

jQuery:

$('.add').click(function() {
    $('.optionBox').append('<input type="text" /><span class="remove">Remove Option</span>');
});

$('.remove').click(function() {
    $(this).parent('div').remove();
});

Answer 1

You need to use event delegation on your remove link code:

$('.add').click(function() {
    $('.block:last').before('<div class="block"><input type="text" /><span class="remove">Remove Option</span></div>');
});
$('.optionBox').on('click','.remove',function() {
    $(this).parent().remove();
});

jsFiddle example

Also, you weren't adding a complete div block to match the other code you had. You left out the <div class="block"> and only added the input and span.

Demo http://jsfiddle.net/34Lbu/

API: .before https://api.jquery.com/before/

Hope rest fits your need :)

code

$('.add').click(function () {
    $(this).before('<div class="block"><input type="text" /><span class="remove">Remove Option</span></div>');
});

$(document).on('click', '.remove', function () {
    $(this).parent('div').remove();
});

EDIT http://jsfiddle.net/amdzakir/gS8u2/38/ To check if all the input fields are filled with values.

$('.add').click(function() {
    flag = true;
    $('input').css('border-color','green');
    $('input').each(function(){
        if ($.trim($(this).val())===''){
            $(this).css('border-color','red');
            flag = false;
        }
    });
    if(flag){
    $(this).before('<div class="block"><input type="text" /><span class="remove">Remove Option</span></div>');
    }
});
$(document).on('click','.remove',function() {
    $(this).parent().remove();
});

Answer 3

try this:

$('.remove').click(function() {
$(this).closest('div').remove();
 });

$('.add').click(function() {
$('.block:last').after('<input type="text" /><span class="remove">Remove    Option</span>');
  });

Answer 4

Here is one way - http://jsfiddle.net/gS8u2/3/

$('.add').click(function () {
    $('.block:last').before(' <div class="block"><input type="text" /><span class="remove">Remove Option</span></div>'); // make sure to add the div too
});

$('body').on('click', '.remove', function () { // use event delegation because you're adding to the DOM
    $(this).parent('.block').remove();
});
