按钮提交两次rails表单

With rails code:

使用rails代码：

= button_to "-", availability_time_span_path(ts) ,:method  =>  :delete, :remote  =>  true

I generate html form, which should be posted via ajax:

我生成html表单，应该通过ajax发布：

<form action="/availability_time_spans/175" class="button_to" data-remote="true" method="post">
  <div>
    <input name="_method" type="hidden" value="delete">
    <input type="submit" value="-">           
    <input name="authenticity_token" type="hidden" value="n962qRxizeXeoEwWYv2AlMfT4nKxxp9ITUxm5wp1nZo=">
  </div>
</form>

When I click on the submit button it is posted twice. Once as: text/javascript from jquery.js:8417 , second time as: text/html from Other

当我点击提交按钮时，它会被发布两次。一次为：来自jquery.js的文本/ javascript：8417，第二次为：来自其他的text / html

2 个解决方案

#1

SOLVED

Problem was I previously inject code using ajax, but renderer response with layout, so the whole jquery was initialized for the second time.

问题是我之前使用ajax注入代码，但渲染器的布局响应，所以整个jquery第二次初始化。

respond_with @ra

If I render response to ajax call with no layout, then it is fine.

如果我在没有布局的情况下呈现对ajax调用的响应，那么就可以了。

respond_with @ra, :layout => false

This could happen for a couple of reasons

这可能由于几个原因而发生

1. You might have the Javascript cached in your browser. Try clearing your cache or opening the page up in a different browser.
2. 您可能在浏览器中缓存了Javascript。尝试清除缓存或在其他浏览器中打开页面。
3. You might be serving up precompiled assets. Make sure you have config.serve_static_assets = false in your config file.
4. 您可能正在提供预编译资产。确保配置文件中有config.serve_static_assets = false。
