Adding And Removing Input Fields With Jquery

I have a problem while adding input fields with jQuery. I set limit to 5 input fields. But if i try to remove input fields, my limit dont work . My var x when i use x-- is not pr

Solution 1:

The problem is you are adding the remove handler inside the add handler instead of using event delegation. So the previously added remove elements will get multiple remove handlers causing x to be decremented multiple times

jQuery(function ($) {
    var max = 5;
    var x = 0;
    $('#add').click(function (e) {
        if (x < max) {
            $('#inp').append('<div><input class = "new_input" type=text name="name[]" placeholder="Unesite podatak"/><a class="remove_field "href="#"> X</a><div><br/>');
            x++;
        }
    });
    $('#inp').on('click', '.remove_field', function (e) {
        e.preventDefault();
        $(this).parent('div').remove();
        x--;
    })
});

Here is a small example, See this link

Hope this will help you.

HTML :

<formid="myForm"><divstyle="margin-bottom:4px;"class="clonedInput"><inputtype="button"class="btnDel"value="Delete"disabled="disabled" /><inputtype="text"name="input1" /></div><div><inputtype="button"id="btnAdd"value="add another name" /></div></form>

JS:

$(document).ready(function() {

    var inputs = 1; 

    $('#btnAdd').click(function() {
        $('.btnDel:disabled').removeAttr('disabled');
        var c = $('.clonedInput:first').clone(true);
            c.children(':text').attr('name','input'+ (++inputs) );
        $('.clonedInput:last').after(c);
    });

    $('.btnDel').click(function() {
        if (confirm('continue delete?')) {
            --inputs;
            $(this).closest('.clonedInput').remove();
            $('.btnDel').attr('disabled',($('.clonedInput').length  < 2));
        }
    });


});
