我正在寻找关于正在推送的表单提交按钮上的页面重新加载工作的建议。我有一个jQuery点击事件，使用AJAX将表单中的信息发送到一个php文件，该文件对从表单收集的数据进行检查，然后将其推送到数据库中。 PHP文件收集信息，信息丢失或提交成功，然后通过AJAX将该信息带回主页面。然后将该信息推送到页面上的错误消息div中，以告知是否存在问题或一切都成功。如果我在1页面上完成所有操作，并且没有其他窗体使用AJAX，这种方式非常有效，但是这一项涉及更多，因此我决定将所有内容都打破以保持整洁。当使用if(array_key_exists("submit",$_POST)) {时，看起来好像在刷新发生后这样做了？那么错误信息就在那里。当我使用AJAX的时候，虽然看起来好像在刷新之前加载了错误消息，但它仍然丢失。以下是我正在处理的内容：表单提交按钮/刷新页面

你可以1.减少你的代码到相关的部分，2.描述你现在的行为相比你想要的行为是什么？ – Jeff
3rd：是否只有_one_ php文件？你应该让他们分开（ui-one和ajax得到它的数据）。 – Jeff
你也应该看看jQuery的[serializeArray（）]（https://api.jquery.com/serializeArray/）！也许读这里：http://stackoverflow.com/questions/1184624/convert-form-data-to-javascript-object-with-jquery/1186309#1186309 – Jeff
