javascript 取得目前網頁網址 (location)

當你需要利用網址來進行判斷時，可以使用 location 來取得當前網址的資訊。

{code}

<script>

  // https://www.example.com/event/page/?p=1&s=2#hash

  location.hash;

  >> "#hash"

  location.host;

  >> "www.example.com"

  location.hostname;

  >> "www.example.com"

  location.href;

  >> "https://www.example.com/?p=1&s=2#hash"

  location.origin;

  >> "https://www.example.com"

  location.pathname;

  >> "/event/page/"

  location.port;

  >> "" // 大多數瀏覽器不會顯示默認端口（http:80，https:443）

  location.protocol;

  >> "https:"

  location.search;

  >> "?p=1&s=2"

</script>
