使用JSON在JavaScript错误：在JSON数据意外非空白字符字符、空白、意外、错误

2023-09-10 18:17:29 作者：涼

我的问题是关于一个错误的我，当我在我的JavaScript函数中使用jQuery.ajax。我搜索，发现类似的问题，但这些问题的帮助了我。

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.

那么，什么是真正奇怪的是，这是工作之前。我花了几天工作的翻译问题，UTF-8，当我之后再次试了一下，这是工作了。我看不到发生了什么，所以也许你可以帮我了解一下。

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.

下面是我的控制器行动的code这就是所谓的AJAX。

Here is the code from my controller action which is called for ajax.

$project =$_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);

这是我的包含AJAX功能的JavaScript功能

And this is my javascript function containing the ajax function

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);
         }
      });       
}

所以，我调试我与萤火虫脚本，它返回是确切的错误 JSON.parse：意外非空格后的JSON数据字符返回JSON.parse（JSON）;的prototype.js（行720）

So I debug my script with Firebug, and the exact error that it returns is "JSON.parse: unexpected non-whitespace character after JSON data return JSON.parse(json); prototype.js (line 720)"

我在当我使用jQuery.ajax两个功能此错误。试图evalJSON（）时，错误发生。

I have this error in both functions when I use jQuery.ajax. The error happens when trying to evalJSON().

任何想法，为什么它不工作了吗？难道是因为这些文件的编码（目前为UTF-8）的？

Any idea why it doesn't work anymore ? Could it be because of the encoding(currently UTF-8) of the files ?

在此先感谢您的帮助！

Thanks in advance for your help !

P.S。也许它没有联系，但是当我打开的prototype.js与Zend Studio的，我在4000行一些警告和2个错误（在行4235和语法错误令牌，缺少分号，。预计。当我发现，我下载了最新版本，并没有改变。

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.
