在ruby HAML中指定过滤器的选项 [英] Specify options for a filter in ruby HAML

问题描述

我想这样做：

 ：javascript {：'data-turbolinks-eval'=> 'false'，：foo => 'bar'} 
 if（someCondition）{
 doSomething（）; 
} 
  

结果是：

 < script'data-turbolinks-eval'='false''foo'='bar'> 
 if（someCondition）{
 doSomething（）; 
} 
< / script> 
  

我能得到的最接近的是：

 ％script {：'data-turbolinks-eval'=> 'false'，：foo => 'bar'} 
 if（someCondition）{
 doSomething（）; 
 
 
 
 
 
 $ b 
缺点是你不能在HAML中缩进你的JS，重新使用：JavaScript过滤器。我很清楚，在大多数情况下，如果您最终在HAML模板中使用复杂的脚本，那么您可能会遇到一些问题。 ，这意味着你做错了，这不是我正在寻找的答案。
解决方案
没有办法将额外的属性传递给：javascript 过滤器。但是，您可以使用：plain 过滤器以及普通的脚本标记来缩进您的JavaScript代码：
 ％script {：'data-turbolinks-eval'=> 'false'，：foo => 'bar'} 
：plain 
 if（someCondition（））{
 doSomething（）; 
 
 $ / code> 

产生：



 < script data-turbolinks-eval ='false'foo ='bar'> 
 if（someCondition（））{
 doSomething（）; 
} 
< / script> 
  




Is there any way to add options (HTML attributes) to HAML filters?

I wanted to do something like this :

:javascript{:'data-turbolinks-eval' => 'false', :foo => 'bar'}
  if(someCondition){
    doSomething();
  }

And the result would be :

<script 'data-turbolinks-eval'='false' 'foo'='bar'>
  if(someCondition){
    doSomething();
  }
</script>

The closest I could get is :

%script{:'data-turbolinks-eval' => 'false', :foo => 'bar'}
  if(someCondition){
  doSomething();
  }

The drawback is that you can't indent your JS in HAML unless you're using the :javascript filter. It's ok for a few lines, but it can get messy quickly.

I'm well aware that in most cases if you end up with a complex script in a HAML template, it means you're doing something wrong and that's not the answer I'm looking for.

解决方案

There is no way to pass extra attributes to the :javascript filter like this. You could however use a :plain filter along with a normal script tag to allow indenting your javascript code:

%script{:'data-turbolinks-eval' => 'false', :foo => 'bar'}
  :plain
    if(someCondition()) {
      doSomething();
    }

produces:

<script data-turbolinks-eval='false' foo='bar'>
  if(someCondition()) {
    doSomething();
  }
</script>
