未捕获到的SyntaxError：意外令牌}，没有可见错误？

Question

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). 当我尝试运行我的Web应用程序的某些功能时，而在index.php（行：30）上收到错误消息“ Uncaught SyntaxError：Unexpected token}”（而其他功能似乎运行正常）。

I've slightly narrowed down the problem. 我已经稍微缩小了范围。 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). 该错误似乎发生在"<?php"开始标签上（我发现这是因为在此标签后添加一行不会改变给出错误的行，但是在标签和错误之前给出了额外的一行行：31）。 I've put the code in note-pad++ to check for hidden characters, I couldn't find anything out of place. 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 gives no syntax errors... Dreamweaver没有给出语法错误...

I've also looked at my AJAX JS functions (which are in a separate file). 我还查看了我的AJAX JS函数（在单独的文件中）。 No syntax errors there, no out of place characters either. 那里没有语法错误，也没有错位字符。

QUESTION: Can anyone see or explain what is causing this error? 问题：谁能看到或解释造成此错误的原因？

I'll place the code surrounding "line: 30" where the error is meant to be. 我将把代码放置在“行：30”周围的错误所在。 The full code is here on github (to large to post all code here): 完整的代码在github上（放大后可以在此处发布所有代码）：

                            echo '</div>'; // <!-- END PANEL --> 
                        echo '</div>'; // <!-- END COLUMN (12) --> 
                    echo '</div>'; // <!-- END ROW -->

In index.php, you have several lines like: 在index.php中，您可以看到几行内容：

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>';

The parameters to showURL are double-quoted, but so is the call to showURL itself. showURL的参数被双引号引起，而showURL本身的调用也被双引号引起来。 The parameters to showURL need to have a double backslash. showURL的参数需要有两个反斜杠。 Eg 例如

onClick="showUrl(\\"All URLs\\")
