Remotipart JS不执行

Question

I have a form that needs to submit a .csv file to the server and then append the words in it to a textarea in my page. I am using Remotipart to upload the .csv using AJAX but I cannot get the javascript in the server response to execute. Here are the relevant parts of my code:

The Form:

=form_tag(upload_canvas_words_admin_page_widget_widget_instance_path(widget.page, widget),:method=>'post',:remote=>true,:multipart=>true,:class=>"upload_words_csv") do
        = label_tag "Upload File"
        = file_field_tag "file"
        = submit_tag "Upload"

The Controller:

def upload_canvas_words
    @csv_text = params[:file].read
end

The .js.haml file:

= remotipart_response do
    - if remotipart_submitted?
        alert('#{@csv_text}');
        alert('!');
    - else 
        alert('WHYYYYY?');

When I look at the response I see the javascript being wrapped in a bunch of html, which I assume has something to do with the iFrame transport. But the javascript never actually executes.

Answer 1

Refer this issue. And try to follow the solution given here.

So what happens is that reponse arrives to the browser with html entity (like " ) inside the textarea. When the js code for evaluation is extracted the html entities are replaced by theirs respective characters (like " to ').

That's a characteristic of a textarea. So it doesn't get executed

在表单中添加data: {type: :script}应该可以解决
