问题描述

我有一个php变量:

$name_of_current_page

在我的视图中可用，我想将该值提供给jquery.最好的方法是像下面这样吗?

which I have available in my view, and I want to make the value available to jquery. Is the best way to do it like the following?

$(document).ready(function () {
            var current page = "<?php echo $name_of_current_page; ?>" ;

});

推荐答案

这实际上取决于您是否使用某种模板引擎.

It really depends if you are using some sort of a template engine.

1. 如果您使用的是纯PHP，则唯一的选择是echo变量:

var current page = "<?php echo $your_var; ?>";

Twig 引擎:

var current page = "{{ your_var }}";

聪明和 RainTPL 引擎:

Smarty and RainTPL engines:

var current page = "{$your_var}";

如您所见，还有其他方法.他们都工作正常.这实际上取决于您要如何编写和组织代码.我个人使用Twig，发现它确实非常容易，快速和简单.

As you can see, there are other ways. All of them work fine. It really depends on how you'd like to write and organize your code. I personally use Twig and find it really easy,fast and straightforward.

此外，正如其他人指出的那样，您可以对服务器进行AJAX调用，并像这样获取变量.我发现该方法耗时，效率低下且不安全.如果选择此方法，则将请求发布到脚本.每个人都可以向该脚本发布/获取请求，从而为一些僵尸程序和DoS/DDoS攻击打开了大门.

Also, as others have pointed out, you can do AJAX calls to the server and fetch the variables like that. I find that method time-consuming, inefficient and insecure. If you choose this method, you will be posting requests to a script. Everybody will be able to do post/get requests to that script which opens your doors to some bots and DoS/DDoS attacks.
