Question

<h2><a href="#" id="addScnt">Add Another Input Box</a></h2>  <div id="p_scents">     
<p id="test">
<input type="text" id="p_scnt" size="20" name="p_scnt" value="" placeholder="Input Value" />    
<input type="text" id="p_scnt" size="20" name="p_scnt" value="" placeholder="Input Value" />
</p> </div> 


$(function() {
        var scntDiv = $('#p_scents');
        var i = $('#p_scents p').size() + 1;

        $('#addScnt').live('click', function() {
                $('<p><label for="p_scnts"><input type="text" id="p_scnt" size="20" name="p_scnt_' + i +'" value="" placeholder="Input Value" /></label> <a href="#" id="remScnt">Remove</a></p>').appendTo(scntDiv);
                i++;

             alert(

                 $("#test > input").size()

             );

                return false;
        });

        $('#remScnt').live('click', function() {
                if( i > 2 ) {
                        $(this).parents('p').remove();
                        i--;
                }
                return false;
        });
});

if i click then value = 2. this is good. and added new input, but if i again click then value agan = 2, should be = 3. I cant use $i. how can i modified function size(), that checked live?

Answer 1

You’re still getting 2 because you have appended the new input outside of your #test paragraph. Update your size() call to check the proper container, by replacing:

$("#test > input").size()

with

scntDiv.find('input').size()
