设置文本区域的最小长度
我正在尝试这样做,以便如果用户没有在文本区域中输入足够的数据,则无法提交我的 WordPress 网站上的评论表单。
我为标题写了这个
<script>
function CheckLength()
{
var msg_area = document.getElementById("Message");
msg_area.innerHTML = "";
if (document.getElementById("commentarea").value.length < 100) {
msg_area.innerHTML = "YOU DID NOT ENTER ENOUGH INFO FOR YOUR REVIEW";
}
else document.getElementById("commentform").submit();
}
</script>
,我的表单看起来像这样
<form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" name="commentform" id="commentform">
<p><input size="36" type="text" name="author" /> Name <span class="required">*</span></p>
<p><input size="36" type="text" name="email" /> Email <span class="required">*</span> (Not Published)</p>
<p><input size="36" type="text" name="url" /> Website</p>
<p><input size="36" type="text" name="server_ip" id="server_ip" /> Server IP/Hostname</p>
<p><?php show_subscription_checkbox(); ?></p>
<p><textarea name="comment" id="commentarea" cols="100%" rows="20"></textarea></p>
<p align="right"><input type="button" name="submit" id="submit" value="Submit Review" tabindex="5" onClick="CheckLength()"></p>
<span id="Message" style="color:#ff0000"></span>
<input type="hidden" name="comment_post_ID" value="<?php echo $id; ?>" />
<?php /* do_action('comment_form', $post->ID); */ ?>
</form>
如果我输入的字符少于 100 个字符,则表单会输出错误“您没有为您的评论输入足够的信息”,但如果我输入的字符多于 100 个字符,则表单会显示错误不提交。如果我更改输入类型以提交,它确实会提交,但如果 << 也没关系。 100
I am trying to make it so that this comment form on my wordpress website can not be submitted if the user does not enter enough data into the textarea.
I wrote this for the header
<script>
function CheckLength()
{
var msg_area = document.getElementById("Message");
msg_area.innerHTML = "";
if (document.getElementById("commentarea").value.length < 100) {
msg_area.innerHTML = "YOU DID NOT ENTER ENOUGH INFO FOR YOUR REVIEW";
}
else document.getElementById("commentform").submit();
}
</script>
And my form looks like this
<form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" name="commentform" id="commentform">
<p><input size="36" type="text" name="author" /> Name <span class="required">*</span></p>
<p><input size="36" type="text" name="email" /> Email <span class="required">*</span> (Not Published)</p>
<p><input size="36" type="text" name="url" /> Website</p>
<p><input size="36" type="text" name="server_ip" id="server_ip" /> Server IP/Hostname</p>
<p><?php show_subscription_checkbox(); ?></p>
<p><textarea name="comment" id="commentarea" cols="100%" rows="20"></textarea></p>
<p align="right"><input type="button" name="submit" id="submit" value="Submit Review" tabindex="5" onClick="CheckLength()"></p>
<span id="Message" style="color:#ff0000"></span>
<input type="hidden" name="comment_post_ID" value="<?php echo $id; ?>" />
<?php /* do_action('comment_form', $post->ID); */ ?>
</form>
The form spits out the error "YOU DID NOT ENTER ENOUGH INFO FOR YOUR REVIEW" if I type in less then 100 chars, but if I type more then a 100 chars the form does not submit. If I change the input type to submit it does submit, but it doesn't matter if < 100

更改输入按钮的名称。
我使用您的标记得到的错误是提交不是一个函数,因为它认为我指的是提交按钮。以下应该有效:
Change the name of your input button.
The error I get using your markup is that submit is not a function, because it thinks I'm referring to the submit button. The following should work:
你能做到这一点吗?
将检查放入表单的“onsubmit”事件中:
您必须更新函数以返回布尔值:
然后从提交按钮中删除 onclick 事件。
Could you do this?
Put the check in the "onsubmit" event for the form:
You'll have to update you function to return a Boolean:
Then remove the onclick event from your submit button.
你能试试这个吗?
Can you try this?
