HTML＆JS-如何显示包含一个以上文本字段的DIV

Question

I am new to development. Right now I have a requirement in a form as I need to display a field with Add and Remove buttons. If user clicks on Add button, app should display one more field. If user clicks on Remove button, app should hide the respective field.

Please suggest me how can I make a Text field to display more than once. Moreover I need get the text field data in PHP hence I should have different name for fields.

Thank you in advance!

It must be helpful for you.

html:

<h2><a href="#" id="addScnt">Add Another Input Box</a></h2>

<div id="p_scents">
<p>
    <label for="p_scnts"><input type="text" id="p_scnt" size="20" name="p_scnt" value="" placeholder="Input Value" /></label>
</p>
</div>

Css:

* { font-family:Arial; }
h2 { padding:0 0 5px 5px; }
h2 a { color: #224f99; }
a { color:#999; text-decoration: none; }
a:hover { color:#802727; }
p { padding:0 0 5px 0; }

input { padding:5px; border:1px solid #999; border-radius:4px; -moz-border-radius:4px; -web-kit-border-radius:4px; -khtml-border-radius:4px; }

javascript:

$(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++;
            return false;
    });

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

Thanks
