我設計了一個表單來發送帶有提交按鈕的消息,但是對於每條消息,我必須使用我的光標單擊submit.How纔會通過點擊我的「Enter」鍵發送消息鍵盤。這裏是我的代碼通過點擊'Enter'鍵發送消息
<div class="message_post" id="myForm">
<form action="" method="POST">
<?php
if($user_to == "new") {
echo "Send a message to your friend <br><br>"; ?>
To: <input type='text' onkeyup='getUsers(this.value, "<?php echo $userLoggedIn; ?>")' name='q' placeholder='Search Username' autocomplete='off' id='search_text_input'>
<?php
echo "<div class='results'</div>";
}
else { // MESSAGE BOX
if($userLoggedIn == $user_to)
echo "<p style='margin-left:275px;'>You can't send message to yourself</p>";
else {
echo "<textarea name='message_body' id='message_textarea' placeholder='Send a message'></textarea>";
echo "<input type='submit' name='post_message' class='info' id='message_submit' value='Send'>";
}
}
?>
</form>
</div>
<script> // Javascript to automatically scrolling down to recent message
var div = document.getElementById("scroll_messages");
if(div != null) {
div.scrollTop = div.scrollHeight;
}
</script>

PHP與客戶端交互無關。 – chris85
這是所有相關的代碼?如果你在一個'form'中有一個'',那麼點擊表單中的Enter將會提交它。 https://codepen.io/anon/pen/LLbxyd –
