A fragment identifier is defined by RFC 3986 as an optional component of a URI reference, and it must conform to a certain syntax. The syntax requires that the fragment identifier be separated from the rest of the URI reference by a # (number sign) character. The separator is not considered part of the fragment identifier.

Basically it looks like http://www.foo.org/foo.html#fragment-identifier.

To use it in Javascript, it is simply "window.location.hash"

This is an imitation of PHP $_GET, in pure Javascript.

From http://www.11tmr.com/11tmr.nsf/D6Plinks/MWHE-695L9Z

function getURLParam(strParamName){
      var strReturn = "";
      var strHref = window.location.href;
      if ( strHref.indexOf("?") > -1 )
    {
            var strQueryString = strHref.substr(strHref.indexOf("?")).toLowerCase();
            var aQueryString = strQueryString.split("&");
            for ( var iParam = 0; iParam < aQueryString.length; iParam++ ){
                      if (
                aQueryString[iParam].indexOf(strParamName.toLowerCase() + "=") > -1 ){
                        var aParam = aQueryString[iParam].split("=");
                        strReturn = aParam[1];
                        break;
                  }
            }
      }
      return unescape(strReturn);
}

今天又學到了一個幫助CSS在IE7、IE6和Firefox上都能跑得一樣，但屬旁門左道的小技巧。　只能心裡腹誹IE不遵守規範…

以下例的css作為例子：
.context_bar_form_field
{
height: 15px;
#height: 15px;
_height: 21px;
}

The first setting will apply to all browsers,

The second setting will only apply to Microsoft Internet Explorer browsers

The third setting will only apply to IE browsers 6.0 and older

今天在跟BT Box的網頁頁面的css奮鬥了一整天，一直無法將下拉式選單蓋過其下面的頁面元素。 就在要放棄之餘，突然發現了這篇文章:

http://css-discuss.incutio.com/?page=OverlappingAndZIndex

才知道原來 z-index 是不能亂設的。 譬如說想要一個dd元素可以蓋過別的頁面元素，這個dd元素的母元素盡量不要設z-index， 而只為此dd元素設一個高過想要蓋過的頁面元素的 z-index 的 z-index。 但似乎這個文章所說尚不止如此，得要好好再讀一下。
