Question

我有5个下拉列表依赖于彼此，并且它们填充了来自sql数据库的5个表中的数据。最后一个下拉列表中包含来自具有超链接的列的数据，例如：http://social.msdn.microsoft.com

我应该在第5个下拉菜单中添加哪些信息才能转到该链接网站？它将此时的列解释为文本。下拉列表是简单的样式版本：

<select>
  <option></option>
</select>

Answer 1

给select一些id，f.e：

<select id="selectbox_with_url">
  <option></option> // here will be your items
</select>

然后使用它：

<script type="text/javascript">
    var urlmenu = document.getElementById('selectbox_with_url');

    urlmenu.onchange = function() {
      // if you want to open it on new tab (or popup) - depends on browser settings:
      window.open(this.options[ this.selectedIndex ].value, '_blank');
      // or if you want to follow that location from option's selected item:
      window.location = this.options[ this.selectedIndex ].value;
    };
</script>

<强> window.open（URL，名称，规格，取代）：名称：

_blank - URL is loaded into a new window. This is default
_parent - URL is loaded into the parent frame
_self - URL replaces the current page
_top - URL replaces any framesets that may be loaded
name - The name of the window (Note: the name does not specify the title of the new window)
