This code will result like this pic http://s24.postimg.org/rlelu0wfp/dynamic_page.png[^]

The question is how to make a Politics News for example show by default without click the button?? I try to think over and over and still doesn't figuring out a way or another to solve this.

Please anyone show me the logic...

Solution 1

add this script tag at end of your body tag. Hope this help.

<script>
    setTimeout("getCatPage('newsCat1')",1000);
</script>
