点击进入提交文本区域 [英] Submitting textarea when clicked enter
问题描述
首先，针对此类问题有很多答案，但由于我使用的是多种形式，因此它们对我都不起作用.
First of all, there are many answers for this type of questions but none of them work for me because I am using multiple forms.
我的问题是，我需要一个脚本，该脚本将在单击Enter时在textarea内提交数据，但是该脚本必须与以下代码一起使用.
My question is, I need a script which will submit the data inside the textarea when clicked enter but the script must work with the code below.
<?php
$inputValue = NULL;
$id = "[1,2,3];"
if(isset($_POST['inputName'])){
$inputValue = $_POST['inputName'];
echo "<br>Input Value: " . $inputValue;
}
if(isset($_GET['id'])){
$getValue = $_GET['id'];
echo "<br>Get Value: " . $getValue;
}
?>
<html>
<head>
<title>Multiple Forms in One Page</title>
</head>
<body>
<br>
<a href="index.php">Main Page</a>
<br>
<?php for($i = 0; $i < 3; $i++){ ?>
<form action="index.php?id=<?php echo $id[$i] ?>" method="post" name="formName">
<textarea name="inputName"></textarea>
<input type="submit" name="submitName">
</form>
<?php } ?>
</body>
</html>
我以前在下面使用此表单，如果一页中有多个表单，则该表单不起作用.
I used to use this one below, which doesn't work if there are multiple forms in one page.
<script>
$(function() {
$('textarea#inputName').on('keydown', function(e) {
if(e.keyCode == 13 && !e.shiftKey){
document.getElementById('formName').submit();
}
});
});
</script>
为了明确起见，如果我在页面中创建单个表单(例如订阅网站新闻)，则上面的脚本将起作用.但是，如果页面中有多个表单(例如，每条帖子后都有Facebook的评论框)，则上述脚本将无法使用.谢谢.
Just to make it clear, If I create a single form in a page (like subscription for newsletter of a site) the script above will work. But if you have more than 1 form in a page (like facebook's comment boxes right after every post) the script above will not work. Thank you.
推荐答案
如何解决
$(this).closest('form').submit();
代替此
document.getElementById('formName').submit();
通过这种方式，仅提交当前文本区域所属的表单.
In this way, only the form to which the current textarea belongs will be submitted.
