Show more entries on click
You will have to accomplish this without pagination. This is a non-javascript way.

{% set page = craft.request.getParam('page') ? craft.request.getParam('page')|number_format : 1 %}
{% set batch = 3 %}
{% set limit = page * batch %}
{% set newPage = page + 1 %}

{% set items = craft.entries.section('projects').limit(limit) %}

{% for item in items %}
    &lt;h2&gt;{{ item.title }}&lt;/h2&gt;
    {# other markup for each item #}
{% endfor %}


&lt;a href="?page={{ newPage }}"&gt;More&lt;/a&gt;


This just increases the limit by the page number and the factor of BATCH while providing the next page number for the button url.
