Question

我试图使用escape_javascript/1，但收到错误。

这是我的＆＃39; poster_controller.ex＆＃39;动作：

def index(conn, params) do
  posts = Repo.all(Post)
  render conn, %{posts: posts}
end

相应的＆＃39; poster_view.ex＆＃39;：

def render("index.json", %{posts: posts}) do
  render("index.js", %{})
end

注意 - 在我让渲染工作之前，我没有将帖子传递到模板中。

以下是被触发的js＆quot; index.js.eex＆＃39;：

$("#foobar").append("<%= escape_javascript(render("foobar.html", %{})) %>");

我尝试渲染的模板＆fo; foobar.html.eex＆＃39;：

<h2>i was placed dynamically</h2>

我尝试渲染的模板foobar.html.eex＆＃39;于：

<div id="foobar"></div>

我看到的错误：

Answer 1

试试这个

$("#foobar").append("<%= escape_javascript(render('foobar.html')) %>");

与Elixir Phoenix一起使用escape_javascript的问题
