Question

我正在使用Rails 3应用。这里一个视图显示用户上传的所有excel文件。 执行所有复选框选定文件的按钮已经存在，每个文件单独删除。现在我应该添加＆＃39;删除＆＃39;按钮删除所选文件。我已经添加了按钮n修改了这个表单 jus调用的函数来显示＆＃34;在执行＆＃34;和＆＃34;在删除＆＃34;现在检查第二个＆＃39;删除＆＃39;按钮是功能。但是每次点击删除它都会打印＆＃34;执行＆＃34;仅在cmd。我想在视图＆＃39;列表中写的AJAX相关代码＆＃39;是问题。请帮助!!告诉我为什么要一直执行？相关代码在这里：

PS：我曾使用if params[:commit]="Delete"＆amp; if params[:delete_button]也在controller.rb中，但没有帮助

list.html.erb（显示所有文件的视图）

我意识到必须对AJAX的Form.serialize(this)做一些事情，它将所有内容序列化。即无论是否存在提交按钮，它都会调用视图中第一个按钮的功能

添加了提交按钮调用了早期按钮的功能本身
