My link in Add_Reviewer.html <a href="#" id="advance_add">Advance Add</a>

My jQuery Code

var $advance_add = $('<div></div>')
    .html('<iframe src="Advance_Add.html" width="100%" name="test" frameborder="0" scrolling="auto" height="100%">')
    .dialog({
        autoOpen: false,
        bgiframe: true,
        width:650,
        minWidth: 650,
        height: 550,
        closeOnEscape:true,
        modal:true,
        title: 'Addvance Add',
        buttons : {

                    "Close" : function() {
                                  $(this).dialog("close");
                                          }
        }
    });
