I want to get 4 type of alert box in different condition, first two alert box is working but last 2 alert does'nt work because of the php variable correctly not coming to the ajax success call back function, How I can solve the above issue?我想在不同条件下获得 4 种类型的警报框,前两个警报框正在工作,但最后 2 个警报不起作用,因为 php 变量没有正确地进入 ajax 成功回调函数,我如何解决上述问题?
You're declaring a variable $temp
within the POST request.您在 POST 请求中声明了一个变量
$temp
。 So it's basically to late to inject this variable - this needs to be done on the initial GET request where the resource (index.html containing your JS for example) is build.因此,注入此变量基本上为时已晚 - 这需要在构建资源(例如包含您的 JS 的 index.html)的初始 GET 请求上完成。
You have two options here.您在这里有两个选择。
General: You should not use plain text responses - especially if you are processing them with JS.一般:您不应该使用纯文本响应 - 特别是如果您使用 JS 处理它们。 Better encode your response as JSON, where you are able to give a structured response.
更好地将您的响应编码为 JSON,您可以在其中提供结构化响应。 See json_encode ( https://www.geeksforgeeks.org/php-json_encode-function/ ).
