我创建了一个数据输入页面。此页面有几个输入框。目前，当用户在输入框中输入数据后按下返回键时，表单被提交。我希望仅在焦点位于提交按钮时才按下返回键启用表单提交。另外，它应该转向下一个输入。我尝试了几种方法，没有用。请建议一种方式
<?php
session_start();
require_once('Connections/hari.php');
$dateindian = date('d-m-Y');
$dateus = date('Y-m-d');
if (isset($_SESSION['EMPNO'])) {
$ECNO = $_SESSION['EMPNO'];
mysql_select_db($database_hari, $hari);
$auth_sql2 = "SELECT pdw FROM users WHERE emp_no='$ECNO'";
$result2 = mysql_query($auth_sql2)or die(mysql_error());
$row2 = mysql_fetch_array($result2);
$count = mysql_num_rows($result2);
$_SESSION['pdw_priv'] = $row2['pdw'];
mysql_free_result($result2);
if ($count == 0 or $_SESSION['pdw_priv'] == 'N') {
header('Location:unauthorised.php');
exit();
}
} else {
header('Location:esl_login.php');
exit();
}
?>

在stackoverflow中搜索类似的问题之后，我发现这正在完成一半的工作。
jQuery('.wql').keypress(function(e){
if ( e.which == 13 )
e.preventDefault();
});
但是这会阻止表单提交，但它不会将焦点转移到下一个输入。有什么方法吗？
答案 0 :(得分：0)
你需要这样的东西，这是Jquery focus on next element with class
的返工请注意，并非所有输入都有允许输入标签的类，包括提交
