How to allow only one radio button to be checked?
提问by Clinteney Hui
{% for each in AnswerQuery %}
<form action={{address}}>
<span>{{each.answer}}</span><input type='radio'>
<span>Votes:{{each.answercount}}</span>
<br>
</form>
{% endfor %}
This is a part my djangotemplate, what it supposed to do is to print out several radio buttons, corresponding to the answers assigned to the buttons. But I don't know why I can check multiple radio buttons, which messed me up. It is supposed to only let me check on one radio button and I had that somehow but I lost it. Any help? Thank you.
这是我的django模板的一部分，它应该做的是打印出几个单选按钮，对应于分配给按钮的答案。但我不知道为什么我可以检查多个单选按钮，这让我很困惑。它应该只让我检查一个单选按钮，我以某种方式拥有它，但我失去了它。有什么帮助吗？谢谢你。

All radio buttons have to have the same name:
所有单选按钮必须具有相同的名称：
<input type='radio' name='foo'>
Only 1 radio button of each group of buttons with the same name can be checked.
每组同名按钮中只能勾选 1 个单选按钮。

Give them the same name, and it will work. By definition Radio buttons will only have one choice, while check boxes can have many.
给它们起相同的名字，它会起作用。根据定义，单选按钮只有一种选择，而复选框可以有多种选择。
<input type="radio" name="Radio1" />
<input type="radio" name="Radio1" />

Just give them the same name throughout the form you are using.
只需在您使用的整个表单中为它们指定相同的名称。
<form><input type="radio" name="selection">
<input type="radio" name="selection">
..
..
</form>

All the radio buttons options must have the same name for you to be able to select one option at a time.
所有单选按钮选项必须具有相同的名称，以便您能够一次选择一个选项。
回答by SuKu
Add "name" attribute and keep the name same for all the radio buttons in a form.
添加“名称”属性并保持表单中所有单选按钮的名称相同。
i.e.,
IE，
<input type="radio" name="test" value="value1"> Value 1
<input type="radio" name="test" value="value2"> Value 2
<input type="radio" name="test" value="value3"> Value 3
Hope that would help.
希望这会有所帮助。
