jQuery Appending unwanted data
<p>Some jQuery function in my code is inserting the string:</p>

<pre><code>jQuery15206649508478338135_1314906667378
</code></pre>

<p>into user-provided feedback. This is happening from multiple forms and it's getting stored in the database, which is really annoying our users. One sample of such code:</p>

<pre><code>$(".sendFeedback").live("click", function() {

    var feedbackText = $(".feedbackText:visible").val();
    var errorElement = $(".feedbackError:first");
    if (isEmptyTrimmed(feedbackText)) {
        errorOut(errorElement, language.pleaseEnterFeedbackText);
        return false;
    }

    var sendFeedback = { email : userSettings.email, firstName : "",lastName : "",primaryRole : "", description : "&lt;br /&gt;Feedback text: &lt;pre&gt;" + feedbackText + "&lt;/pre&gt;",
        sendNotification : false, isPartner : false , formType : 3};

    callService("sendFeedback", sendFeedback);
    currentMessage = language.thankYouForTheFeedback;
    loadScreenByHash("mainScreen");
});

function callService(serviceName, data, callbackFunction) {
    var json = $.toJSON(data);
    json = "{ " + serviceName + ": " + json + " }";
    $.post(serviceUrl, json,
            function(response) {
                if (callbackFunction) {
                    callbackFunction(response);
                }
            }, 'json').error(function() {
        if (callbackFunction) {
            callbackFunction();
        }
    });
}
</code></pre>

<p>The callService function directs to a Java server, so I'm doubting it's getting inserted there. The java server writes to the DB, so I'm pretty sure it's getting inserted in the javascript code.</p>

<p>It happens other places as well, and they follow the same formula: read user input with .val(), pass to callService (sometimes through additional JS function). A sample of the output data:</p>

<blockquote>
  <p>I created a quiz but can not figure out how to run it for my class. 
  there are no buttons that say run
  quizjQuery15206649508478338135_1314906667378? Customer Name</p>
</blockquote>

<p>I've also seen it appended at the end of a string. Let me know if anyone has seen this before.</p>
