Just to show how UTTERLY BRAINDEAD that code is, try this:

var txt = "In math, 3 < 5 is true and 10 > 12 is false";
alert( removeHtmlTag( txt, 9999 ) );

using that removeHtmlTag code, as written.

You get an alert of In math, 3 12 is false

The stupid code thinks that "< 5 is true and 10 >" is an HTML tag!!!

*********

Anyway, aside from the code being both braindead and ugly as pig snot, if you don't want to eliminate HTML tags from the blogposts, then you *could* simply change that function to

function removeHtmlTag( strx, chop ) { return strx; }

If you do want to remove HTML tags, then do it right:

function removeHtmlTag( strx, chop ) /* ignores chop! */
{
    var re = /\<\/?[a-z][^\>]*\>/ig;
    return strx.replace( re, "" );
}
