如何设置 HTML select 元素的默认值？

Question

I thought that adding a "value" attribute set on the <select> element below would cause the <option> containing my provided "value" to be selected by default:

<select name="hall" id="hall" value="3">
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>
</select>

However, this did not work as I had expected. How can I set which <option> element is selected by default?

Set selected="selected" for the option you want to be the default.

<option selected="selected">
3
</option>
