You had a unescaped "in the onclick handler, escape it with \"

How to reproduce this error:
如何重现此错误：
SyntaxError: missing ) after argument list
This code produces the error:
此代码产生错误：
<html>
<body>
<script type="text/javascript" src="jquery-2.1.0.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
}
</script>
</body>
</html>
If you run this and look at the error output in firebug, you get this error. The empty function passed into 'ready' is not closed. Fix it like this:
如果您运行此程序并查看 firebug 中的错误输出，则会收到此错误。传递给 'ready' 的空函数没有关闭。像这样修复它：
<html>
<body>
<script type="text/javascript" src="jquery-2.1.0.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
}); //<-- notice the right parenthesis and semicolon
</script>
</body>
</html>
And then the Javascript is interpreted correctly.
然后 Javascript 被正确解释。

For me, once there was a mistake in spelling of function
对我来说，曾经有一次函数拼写错误
For e.g. instead of
例如代替
$(document).ready(function(){
});
I wrote
我写
$(document).ready(funciton(){
});
So keep that also in check
所以也要检查一下

I faced the same issue in below scenario yesterday. However I fixed it as shown below. But it would be great if someone can explain me as to why this error was coming specifically in my case.
我昨天在下面的场景中遇到了同样的问题。但是我修复了它，如下所示。但是，如果有人能向我解释为什么在我的情况下会出现此错误，那就太好了。
pasted content of index.ejs file that gave the error in the browser when I run my node file "app.js". It has a route "/blogs" that redirects to "index.ejs" file.
当我运行我的节点文件“app.js”时，index.ejs 文件的粘贴内容在浏览器中给出了错误。它有一个路由“/blogs”，重定向到“index.ejs”文件。
<%= include partials/header %>
<h1>Index Page</h1>
<% blogs.forEach(function(blog){ %>
<div>
<h2><%= blog.title %></h2>
<image src="<%= blog.image %>">
<span><%= blog.created %></span>
<p><%= blog.body %></p>
</div>
<% }) %>
<%= include partials/footer %>
The error that came on the browser:
浏览器上出现的错误：
SyntaxError: missing ) after argument list in /home/ubuntu/workspace/RESTful/RESTfulBlogApp/views/index.ejs while compiling ejs
SyntaxError: missing ) 在 /home/ubuntu/workspace/RESTful/RESTfulBlogApp/views/index.ejs 中的参数列表之后编译 ejs
How I fixed it: I removed "=" in the include statements at the top and the bottom and it worked fine.
我是如何修复它的：我在顶部和底部的包含语句中删除了“=”，它运行良好。

SyntaxError: missing ) after argument list.
SyntaxError: missing ) 在参数列表之后。
the issue also may occur if you pass string directly without a single or double quote.
如果您直接传递字符串而没有单引号或双引号，也可能会出现此问题。
$('#contentData').append("<div class='media'><div class='media-body'><a class='btn' href='" + type + "' onclick=\"(canLaunch(' + v.LibraryItemName + '))\">View »</a></div></div>").
so always keep the habit to pass in a quote like
所以总是保持传递这样的引用的习惯
onclick=\"(canLaunch(\'' + v.LibraryItemName + '\'))"\

用：
my_function({width:12});
Instead of:
代替：
my_function(width:12);
