html_options is a custom function that creates html option group with provided data. It takes care of which item(s) are selected by default as well. Required attributes are values and output, unless you use options instead.
自定义函数 html_options 根据给定的数据创建选项组. 该函数可以指定哪些元素被选定. 要么必须指定 values 和 ouput 属性,要么指定 options 替代.
If a given value is an array, it will treat it as an html OPTGROUP, and display the groups. Recursion is supported with OPTGROUP. All output is XHTML compatible.
如果给定值是数组,将作为 OPTGROUP 处理,且支持递归. 所有的输出与 XHTML 兼容.
If the optional name attribute is given, the <select name="groupname"></select> tags will enclose the option list. Otherwise only the option list is generated.
如果指定了可选属性 name,该选项列表将将被置于<select name="groupname"></select>标签对中. 如果没有指定,那么只产生选项列表.
All parameters that are not in the list above are printed as name/value-pairs inside the <select>-tag. They are ignored if the optional name is not given.
上表未提到的其它参数在 <select> 标签中以"名称/属性"对的方式显示. 如果没有指定可选属性 name 这些参数将被忽略.
