我的表单未遵守“评论”字段的required
属性。我想要它,以便当用户提交表单时,它显示“请填写字段”,但用户可以立即提交表单。
<form class="form-part" method="post" action="contact_form.php" name="contactform" id="contactform" onSubmit="return checkForm1();">
<input id="name" type="text" name="name" size="30" title="Name" required>
<input id="email" type="text" name="email" size="30" title="Email" required>
<textarea rows="3" id="comments" name="comments" cols="40" title="Tell us what you think!" required></textarea>
<input type="submit" name="Submit" alt="Send">
</form>

一个非常简单的检查功能可能是:
function checkForm1(frm){
if (frm.comments.value==''){
alert('Please leave a comment.' );
return false;
else return true;
}
为此,您需要将表单标记扩展为:
<form ... onsubmitt="return checkForm1(this)">

在您的代码中从标记中删除
<form class="form-part" method="post" action="contact_form.php" name="contactform" id="contactform">
<input id="email" type="text" name="email" size="30" title="Email" required>
<textarea rows="3" id="comments" name="comments" cols="40" title="Tell us what you think!" required></textarea>
<input type="submit" name="Submit" alt="Send" onSubmit="return checkForm1();">
</form>
现在运行。并告诉我表格是否显示。
