html - 如何设置HTML的默认值 <select>元件？(How can I set the default value for an HTML <select> element?)

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:

(我认为在下面的<select>元素上添加"value"属性集会导致默认情况下选中包含我提供的"value"的<option> ：)

 <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.

(但是，这没有按我预期的那样工作。)

How can I set which <option> element is selected by default?
