Correct method according to W3C will be selected = "selected" as noted here http://www.w3.org/TR/html-markup/option.html#option
根据 W3C 的正确方法将被选择 = "selected" 如此处所述 http://www.w3.org/TR/html-markup/option.html#option

If you want set selected more than 1 option in select, dont forget add to select attribute multiple and add to name of select [] else it doesnt work.
如果您想在选择中设置多于 1 个选项，请不要忘记添加选择属性多个并添加到选择 [] 的名称，否则它不起作用。
<select name="mega_select[]" multiple>
<option value="some" selected="selected">some</option>
<option value="value" selected="selected">value</option>
<option value="non">non</option>
</select>
