POError with JSON in javascript : unexpected non-whitespace character after JSON data
text
Body
copied!<p>My question is about an error I have when I use jQuery.ajax in my javascript function. I searched and found similar question, but none of these questions helped me.</p> <p>So, what's really weird is that it was working before. I spent a few days working on translations problems with UTF-8 and when I tried it again after, it was working anymore. I can't see what happened so maybe you can help me find out. </p> <p>Here is the code from my controller action which is called for ajax.</p> <pre><code>$project =$_GET['project']; //Call private function getQuota $quotaTab = $this->getQuota($project); $this->_helper->getHelper('viewRenderer')->setNoRender(); Zend_Layout::getMvcInstance()->disableLayout(); // Encode data to return $return = array( 'quota' => $quotaTab[0], 'usedSpace' => $quotaTab[1], 'usedPercentage' => $quotaTab[2] ); $return = Zend_Json::encode($return); $this->getResponse()->setBody($return); </code></pre> <p>And this is my javascript function containing the ajax function</p> <pre><code>function changeQuota() { var fileset = document.getElementById('fileset'); jQuery.ajax({ url: '/filesets/quota/', data: ({ project: fileset.value, ajaxCall: true}), success: function(response) { //Decode the JSON response var result = response.evalJSON(); // Set the new value of current quota $('currentQuota').value = result.quota; var strUsed = <?php echo "' ".$this->translate("used")."'";?>; $('usedQuota').innerHTML = result.usedPercentage.concat(strUsed); var suggestQuota = Math.round(parseFloat(result.quota) + parseFloat(result.quota/10)); $('quota').value = suggestQuota; $('usedSpace').value = Math.round(result.usedSpace); } }); } </code></pre> <p>So I debug my script with Firebug, and the exact error that it returns is <strong>"JSON.parse: unexpected non-whitespace character after JSON data</strong><br> <strong>return JSON.parse(json); prototype.js (line 720)"</strong></p> <p>I have this error in both functions when I use jQuery.ajax. The error happens when trying to evalJSON().</p> <p>Any idea why it doesn't work anymore ? Could it be because of the encoding(currently UTF-8) of the files ? </p> <p>Thanks in advance for your help ! </p> <p>P.S. Maybe it's not linked, but when I open prototype.js with Zend Studio, I have some warnings and 2 errors("missing semi-colon" at line 4235 and "Syntax error on token ",", . expected" at line 4000. When I noticed that, I downloaded latest version and it didn't change.</p>
