title: nodejs express, ajax posting w/ jquery and receiving response
body: <p>Having some trouble getting express to respond properly to my jquery ajax request. The actual posting is working fine, but no matter what I try I cant seem to actually get a data response from my app that I can use. At first it was just posting and hanging constantly, and like a minute later it would respond with an alert that said something like "XML Document loaded" (have no idea where it was coming from) -- Anyways, now its giving me</p>
  
  <p>SyntaxError: Unexpected token ILLEGAL
      at parse (native)
      at IncomingMessage.
  
  <p>In my express App, I have:</p>
  
  <pre><code>    app.post('/save', function(req, res) {
        console.log(req.body.objectData);
        res.contentType('json');
        res.send({ some: 'json' });
      });
  </code></pre>
  
  <p>and in my jquery:</p>
  
  <pre><code>  $.ajax({
      url: "/save",
      type: "POST",
      dataType: "json",
      data: {objectData: someObject},
      contentType: "application/json",
      cache: false,
      timeout: 5000,
      complete: function() {
        //called when complete
        console.log('process complete');
      },
  
      success: function(data) {
        console.log(data);
        console.log('process sucess');
     },
  
      error: function() {
        console.log('process error');
      },
    });
  </code></pre>
