Question

这是我的test.rb

require 'sinatra'

require  'json/pure'

get '/2015/:teachername/teaching/:subjectname' do

 content_type :json

 {

     "message" => "#{params[:teachername]} teaching #{params[:subjectname]}."   

 }.to_json

end

一切都很好，比如当我通过url localhost：4567/2015 / Anil / teaching / Sunil访问时，但是当我在jquery中访问这个url时，我无法通过：teachername和：subjectname。

这是我的test.html

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>


<script>

  $.getJSON('/2015/:teachername/teaching/:subjectname', function(data) {

    alert(data.message);

  });

</script>

Answer 1

您必须通过在Javascript中附加参数来构建URL字符串。

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script>
  var teachername = 'Anil';
  var subjectname = 'Sunil';

  $.getJSON('/2015/'+teachername+'/teaching/'+subjectname, function(data) {
    alert(data.message);
  });
</script>

在jquery中打印来自url的传递值
