問題描述
我在 HTML 方面沒有太多經(jīng)驗.我希望創(chuàng)建一個簡單的列表框，但要求之一是禁止多選.列表框的大部分代碼都是這樣的 -
I don't have much experience in HTML. I am looking to create a simple listbox, but one of the requirements is to DISALLOW multiple selection. Most of the code for listboxes goes like this -
<select name="sometext" multiple="multiple">
<option>text1</option>
<option>text2</option>
<option>text3</option>
<option>text4</option>
<option>text5</option>
</select>
但這允許多選.
這里，有人問了類似的問題，但最佳"答案被否決了.所以我不確定這還能怎么做.請幫忙.
Here, a similar question was asked, but the "best" answer has been downvoted. So I am not sure how else this could be done. Please help.
推薦答案
只要使用size屬性即可:
Just use the size attribute:
<select name="sometext" size="5">
<option>text1</option>
<option>text2</option>
<option>text3</option>
<option>text4</option>
<option>text5</option>
</select>
為了澄清，添加 size 屬性并沒有刪除多選.
To clarify, adding the size attribute did not remove the multiple selection.
單選有效，因為您刪除了 multiple="multiple" 屬性.
The single selection works because you removed the multiple="multiple" attribute.
添加 size="5" 屬性仍然是個好主意，這意味著至少要顯示 5 行.查看完整參考這里
Adding the size="5" attribute is still a good idea, it means that at least 5 lines must be displayed. See the full reference here
