我想制作一个简单的验证表单,它会在取消选中时显示警告消息<div>
。
这是什么,我到现在为止。
<form action="result.php" method="post">
<b>1st question:</b><br />
Option 1 <input type="radio" name="question1" value="Option1" /><br />
Option 2 <input type="radio" name="question1" value="Option2" /><br />
Option 3 <input type="radio" name="question1" value="Option3" /><br />
Option 4 <input type="radio" name="question1" value="Option4" /><br />
<br />
<b>2nd question:</b><br />
Option 1 <input type="radio" name="question2" value="Option1" /><br />
Option 2 <input type="radio" name="question2" value="Option2" /><br />
Option 3 <input type="radio" name="question2" value="Option3" /><br />
Option 4 <input type="radio" name="question2" value="Option4" /><br />
<br />
<input type="submit" value="submit" />
</form>`
