【中文标题】如何在不完成 Bootstrap 中的一个步骤的情况下禁用进入下一步？【英文标题】：How to disable going to next step without completing one step in Bootstrap? 【发布时间】：2016-08-25 09:27:32 【问题描述】：我创建了一个 Bootstrap 小部件进度显示表单。它有 6 个步骤。我的问题是
-
当用户在第一步时，如何禁用所有其他步骤？
当用户完成第一步后，授予移动到第二步的权限并禁用所有其他步骤，直到用户完成当前步骤。
如何阻止转到上一步？
这是我的代码
<?php
include_once 'dbconnect.php';
?>
<?php
if (isset($_POST['btn-signup']))
$Mnumber = $_POST['Mnumber'];
$emailErr = "";
$email = $_POST['email'];
if (!filter_var($email, FILTER_VALIDATE_EMAIL))
$emailErr = "Invalid email format";
$fname = $_POST['fname'];
$address = $_POST['address'];
$sitename = $_POST['sitename'];
$payment = $_POST['payment'];
$title = $_POST['title'];
$descr = $_POST['descr'];
$step1 = $_POST['step1'];
$new_fname = $_POST['sitename'];
$xxx = mysql_query("SELECT fname FROM txfgf WHERE sitename = '$new_fname'") or die(mysql_error());
$yyy = mysql_fetch_row($xxx);
if (mysql_num_rows($xxx) > 0)
echo "<script type='text/javascript'>alert('From this Name already there is a website,Tryout with different Web site Name !')</script>";
else
$query = mysql_query("INSERT INTO txfgf(Mnumber,email,fname,address,sitename,payment,title,descr) VALUES('$Mnumber','$email','$fname','$address','$sitename','$payment','$title','$descr')");
echo "<script>
alert(' You have registered Successfully !');
</script>";

【问题讨论】：
【参考方案1】：here is plunker 解决您的问题
我已将disabled 课程添加到其他尚未完成的潜水中。
如果上一部分已完成，请编写一个脚本来删除下一个 disabled 类。
这是css
.disabled
cursor: not - allowed;
pointer - events: none;
opacity: .65;
修改了html代码
<div class="row step">
<div id="div1" class="col-md-2" onclick="javascript: resetActive(event, 0, 'step-1');">
<span class="fa fa-file-text-o"></span>
<p>Registration Form</p>
