javascript - Inline Javascript not working properly on rerendering a partial in ruby on rails 3.1

Question

In my project we have inline javascript in a partial which is using some instance variables. When we are rerendering that partial after successful ajax call that script is not running.

Can you please help me that how I can solve that problem?

For e.g.

_partial.html.erb

 <div class="someclass"></div>
 <script>
    $(document).ready(function(){
       $(".someclass").hide();
    });
 </script>

The scrip tag is not running on replacing this partial from js.erb file.

Answer 1

您的页面已加载。这ready件事很久以前就过去了，现在没人听了。

因此，如果您$(document).ready在 Ajax 中加载了脚本，则代码将永远不会被执行。

解决方案：

删除“就绪”事件并直接触发代码：

 <div class="someclass"></div>
 <script>
   $(".someclass").hide();
 </script>

Answer 2

在我看来，在 ajax 成功事件上手动更新 DOM 后未触发就绪事件，因此未执行回调函数。

Answer 3

最后，我发现我认为非常适合我的要求的答案是将 javascript 放入部分中并相应地在和 otherjs.erb中呈现它。html.erbjs.erb files
