Javascript 打印jquery中url传递的值

这是我的测试

require 'sinatra'

require  'json/pure'

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

 content_type :json

 {

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

 }.to_json

end

这一切都很好，比如当我通过url localhost:4567/2015/Anil/teaching/Sunil访问时，但当我在jquery中访问此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>

$.getJSON（'/2015/：teachername/teaching/：subjectname'，函数（数据）{
警报（数据、消息）；
});

您必须通过在Javascript中添加参数来构造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>

var teachername='Anil'；
var subjectname='Sunil'；
$.getJSON（'/2015/'+teachername+'/teaching/'+subjectname，函数（数据）{
警报（数据、消息）；
});
