嗨,有人可以告诉我下面的代码有什么问题吗?

Selected="selected" not working for me.

Selected="selected" 对我不起作用。

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
    <select id="tstselect" name="tstselect" onchange="showselected(this.value);">
    <option value="0" >0</option>
    <option value="1" >1</option>
    <option value="2" >2</option>
    <option value="3" selected="selected">3</option>
    </select>

Thanks in advance

提前致谢

You probably have something on your page selecting the value. You mightbe able to quickly verify that if the same value is still selected after changing the order of the options in the html...

您的页面上可能有一些选择该值的内容。您也许能够快速验证在更改 html 中选项的顺序后是否仍然选择了相同的值...
