使用JavaScript在Rails应用中通过POST发送富文本

Question

I have in APP A the following rich text:

A nice basketball

• because I say so
• because my mother says so
• because my dog says so

In index.html.erb this rich text is accessible through product.body_html , which I load into a Javascript object called myProduct :

var myProduct= new Object(); 
myProduct.desc ='<%= JSON.generate(raw(product.body_html), quirks_mode: true) %>';

Then I send this object via POST to my API in APP B using Javascript:

var url = appBURL + "/myapi/method";
  $.ajax({
      type: "POST",
      url: url,
      data: JSON.stringify(myProduct),
      contentType: "application/json; charset=utf-8",
      dataType: "json",
      success: function(data){
        // data.desc should contain the same rich text
        $(".myDiv").html(data.desc);
      }
  });

And I get an answer back data.desc in app A that should contain the same rich text. But when I display data.desc inside a <div> what I see printed on the screen is this

"<p>A nice basketball</p> <ul> <li>because I say so</li> <li>because my mother says so</li> <li>because my dog says so</li> </ul>" 

And what I'm actually inserting in that <div> (ie, the contents of data.desc ) is this

"<p>A nice basketball</p>
<ul>
<li>because I say so</li>
<li>because my mother says so</li>
<li>kjh</li>
</ul>"

The client in APP A is adding these quotes. Why?

If I add in APP A the description like this:

myProduct.desc ='<%= raw(product.body_html) %>';

Then it works with normal text (and it doesn't add the quotes), but as soon as I have rich text it produces a syntax error when running the javascript.

当您在APP B中渲染文本时，请按以下方式渲染：

(CGI::unescapeHTML data.desc).html_safe
