phpcms中使用js时遇到的难题估计还没有人关注过

Jun 23, 2016 pm 01:40 PM

比如
$('#moveImage').bind('dblclick',function(){
      window.location.href='{APP_PATH}index.php?m=special&c=index&a=special&siteid={$siteid}';
})
中的要写大括号标签,这么写肯定不行,要被解析错误的
但是要转义,试了一下也不行

$('#moveImage').bind('dblclick',function(){
      window.location.href='\{APP_PATH\}index.php?m=special&c=index&a=special&siteid=\{$siteid\}';

})
那么问题来了,难道js中真的没有办法写入phpcms的标签符号吗,我估计这么多年了,我是第一个关注这种问题的,因为全论坛没有这方面的帖子.


回复讨论(解决方案)

应该是你写的不符合规范,否则就不可能只有你会遇到问题

1、APP_PATH 是什么?
如果是常量,那么你这样写在串中是错误的
如果不是常量,则一定有替换字符串为值的地方。那么该不该有大括号括起就是个问题了。即替换时是否会将大括号一起替换掉
这要看看做这事的代码了
2、在 js 中,除非有特殊需要是不必书写而外的路径的,如果写了则必须是绝对路径,否则就会被解释为子目录了
而你的 APP_PATH 显然是项目目录
3、你可以在浏览器中查看网页源文件,看看这部分变成什么了

不好意思刚睡醒脑子有点不清醒不太理解你的意思。

PHPCMS的模板引擎比较简单高效,也就是说只要花括号开始闭合都在同一行内且中间没有空格(loop、for、if、pc、php以及调用函数和允许出现空格 ),那么都会被模板引擎匹配到(常量、变量、自增自减等)。
详细的可以看模板引擎phpcms/libs/classes/template_cache.class.php中template_parse()方法。

然后看你最后一句,我暂且理解为在模板文件中script里调用模板标签,可以准确的告诉你是可以的,因为在模板引擎中,并没有对标签调用位置进行判断。

<script type="text/javascript">alert({APP_PATH});</script>
Copy after login

会弹出站点地址

所以,只要是在模板文件中,绝对可以在script中调用模板标签,反之,如果要在script中输出"{APP_PATH}",貌似只能通过加转义实现。
当然如果任性地在js文件中调用那就.......2333333333333333

<script type="text/javascript">alert("{APP_PATH}");</script>
Copy after login
Copy after login
Copy after login
Copy after login

行不行的?

<script type="text/javascript">alert("{APP_PATH}");</script>
Copy after login
Copy after login
Copy after login
Copy after login

这样能运行么

<script type="text/javascript">alert("{APP_PATH}");</script>
Copy after login
Copy after login
Copy after login
Copy after login

这样能运行么


那个楼主在PHPCMS论坛提问了然后就放弃这边结贴了,个西八= =。回复楼上,可以的~!!!

var path='{APP_PATH}';
$('#moveImage').bind('dblclick',function(){
window.location.href=path+'index.php?m=special&c=index&a=special&siteid={$siteid}';
})

呵呵

随便看看,偶不说话


<script type="text/javascript">alert("{APP_PATH}");</script>
Copy after login
Copy after login
Copy after login
Copy after login

这样能运行么

想要得分很简单,你只要解决这个问题就行,又想得分,又不想解决问题,你回家问问你妈,有这好事吗

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
