Php 如何为验证码添加重新加载链接？

php javascript ajax forms

Php 如何为验证码添加重新加载链接？,php,javascript,ajax,forms,captcha,Php,Javascript,Ajax,Forms,Captcha,我对这个问题做了一些研究，但是每个php表单都不同，所以其他人的解决方案可能不适合我。我想有一个链接，说重新加载验证码，当它点击它重新加载而不刷新页面。我的表单确实使用了AJAX和javascript，我猜这就是正确实现这一点所需要的我的表单的javascript如下所示： jQuery(document).ready(function() { $('.contactform').submit(function() { var action = $(this).attr('acti

我对这个问题做了一些研究，但是每个php表单都不同，所以其他人的解决方案可能不适合我。我想有一个链接，说重新加载验证码，当它点击它重新加载而不刷新页面。我的表单确实使用了AJAX和javascript，我猜这就是正确实现这一点所需要的

我的表单的javascript如下所示：

jQuery(document).ready(function() {

          '<img src="assets/ajax-loader.gif" class="loader" />');
    $('.message', this).slideUp(750, function() {
        $(this).hide();
        $.post(action, {
            name: $('.name', form).val(),
            email: $('.email', form).val(),
            phone: $('.phone', form).val(),

我把$msg中的电子邮件HTML去掉了，因为它的代码太多了，我认为没有必要包含它

    $('.message', this).slideUp(750, function() {
        $(this).hide();
        $.post(action, {

            email: $('.email', form).val(),

有人知道我应该一步一步地做什么吗？注意：我仍然是php和ajax的业余爱好者。。。哦，不，如果您认为：

这应该给您一个启动，这将对image.php生成的图像进行计算，并更新session/cookie变量，那么我不想使用reCaptcha。我们更新映像以包含一个缓存破坏字符串，以便它应该更新映像和会话变量

HTML

显然没有经过测试，但应该会给你一个很好的开始来实现它。

你的第一句话是关于做研究的承诺，但是在PHP代码的页面之后，你失去了我。试着做一个最小的测试用例，或者至少切掉一大块不相关的代码错误记录，等等来帮助我们。另外，解释一下什么方法最接近你，什么方法不起作用——就我个人而言，我更愿意解决一个特定的问题/bug，而不是在业余时间做一件工作。第一个是有趣的，第二个只是工作。当然，这只是我的看法。是什么为您生成了验证码图像？这样想吧。。。当页面加载时，服务器会写出一个标记，告诉用户的浏览器请求验证码图像。您需要jQuery请求新的验证码图像，然后使用jQuery将原始验证码图像替换为新的验证码图像。我知道你们是来帮忙的，我非常感谢，我也尽了最大努力解释。上面的长php代码是我提交查询的php处理表单。。。我把代码放在那里，以防你们需要看到它来理解我的表单是如何工作的。通常我会被告知我没有包含所有必要的代码，所以我习惯于发布我认为相关的所有相关信息。@monkey扳手-非常有意义！现在对于像我这样的业余爱好者来说，用拇指吮吸代码并写出代码来让它工作是另一回事了。哈哈。这就是为什么我需要你们的帮助。把问题分解成更小的部分总是比较容易的。您试图添加的功能就是一个很好的例子，通过这样做，您可以学到很多东西。创建一个测试页面，在那里抛出一个和一个，并尝试在单击div时使用jQuery切换图像。操作简单，jQuery文档站点上有大量的示例。在解决整个问题之前，您需要了解各个概念是如何工作的。
