Admin-ajax.php 400错误请求-我的代码有什么问题？

时间：2018-06-08 作者：David Smith

我从管理员ajax收到400个错误请求。php&；pagespeed insights的警告告诉我这是一个问题。

您能在我们的管理ajax中看到代码中的任何明显问题吗。php文件？

通过单击inspect element，然后在打开network选项卡的情况下刷新，然后单击initiator，我可以在代码旁边看到一个红色的x，这似乎是导致问题的原因。这有什么问题？

此处的代码：

var t, e, n, o = 0, u = function(t, e) {
    return "function" != typeof t || t.replaced ? t : (e.replaced = !0,

使用chrome开发工具，我找到了创建http请求的文件。

此文件是主题。min.js，我查看了文件；可以看到“porto\\u refresh\\u cart\\u fragments”，虽然文件已缩小，所以我不知道要删除什么。

在使用网站取消整理文件后，我需要删除的内容更加清晰，因此我从文件中删除了代码，因为网站上没有购物车，所以它已经过时。

管理ajax的http请求。来自porto_refresh_cart_片段的php现在已修复。我只是觉得我应该把这些信息放在这里以备将来参考，以防其他人也遇到同样的问题，虽然这只是因为我们没有购物车才起作用，但它可能会帮助一些人。

结束

特定WordPress页面的JavaScript

我有一个用Wordpress运行的网站。有一个特定的页面，我需要用户上传图片，放大/缩小，并将图片裁剪成圆形打印出来。所有这些都需要通过移动设备完成。我在Github上找到了croppie，并安装了所有文件。但是，脚本不起作用。我认为问题是WP，但尚未在网上找到任何解决方案。J/S和wordpress有问题吗？非常感谢您的帮助！
