未捕获到的SyntaxError:意外的令牌}，没有可见的错误? [英] Uncaught SyntaxError: Unexpected token }, no visible error?
问题描述
当我尝试运行Web应用程序的某些功能时(而其他功能似乎运行正常)，我在index.php(行:30)上收到错误消息"Uncaught SyntaxError:Unexpected token}".
I am getting the error "Uncaught SyntaxError: Unexpected token }" on index.php (line: 30) when i try and run certain functions of my web app (while other functions seem to work fine).
我已经稍微缩小了范围.该错误似乎发生在"<?php"开头标记处(我发现这是因为在此标记后添加一行不会改变给出该错误的行，而是在该标记之前添加了一行，并且为该行给出了错误: 31).我已将代码放在记事本++中，以检查隐藏的字符，找不到任何不合适的东西. Dreamweaver没有语法错误...
I've slightly narrowed down the problem. The error seems to occur at the "<?php" opening tag (I found this because adding a line after this tag doesn't change the line the error is given for, but an extra line before the tag and the error is given for line: 31). I've put the code in note-pad++ to check for hidden characters, I couldn't find anything out of place. Dreamweaver gives no syntax errors...
我还查看了我的AJAX JS函数(位于单独的文件中).那里没有语法错误，也没有错位的字符.
I've also looked at my AJAX JS functions (which are in a separate file). No syntax errors there, no out of place characters either.
问题:谁能看到或解释造成此错误的原因?
QUESTION: Can anyone see or explain what is causing this error?
我将把代码放置在行:30"周围，将其视为错误所在.完整的代码在github上(放大后可以在此处发布所有代码):
I'll place the code surrounding "line: 30" where the error is meant to be. The full code is here on github (to large to post all code here):
https://github.com/bcdawber/URL-Vault-Web-Application
代码:
</head>
<body onLoad="showUrl('All URLs')">
//console suggests error is somewhere here?
<?php
session_start();
if(isset($_SESSION['userid'])) {
echo '<div class="container">';
echo '<div class="panel" id="backgroundPanel">';
echo '<div class="row">';
echo '<div class="large-12 columns">';
echo '<div class="panel">';
echo '<p><h2 id="title">URL VAULT</h2>';
echo '<h4 id="title">A Web Application for Storing URLs to Online Media.</h4></p>';
echo '</div>'; // <!-- END PANEL -->
echo '</div>'; // <!-- END COLUMN (12) -->
echo '</div>'; // <!-- END ROW -->
...........
推荐答案
在index.php中，您有以下几行:
In index.php, you have several lines like:
echo '<a href="#" class="small button radius expand" onClick="showUrl("All URLs");return false;"/>All URLs</a>';
echo '<a href="#" class="small button radius expand" onClick="showUrl("Television");return false;"/>T.V URLs</a>';
echo '<a href="#" class="small button radius expand" onClick="showUrl("Movie");return false;"/>Movie URLs</a>';
echo '<a href="#" class="small button radius expand" onClick="showUrl("Music");return false;"/>Music URLs</a>';
showURL的参数被双引号引起来，而对showURL本身的调用也是如此. showURL的参数需要有两个反斜杠.例如
The parameters to showURL are double-quoted, but so is the call to showURL itself. The parameters to showURL need to have a double backslash. E.g.
onClick="showUrl(\\"All URLs\\")
