Uncaught syntaxerror missing after argument list ошибка

The JavaScript exception «missing ) after argument list» occurs when there is an error
with how a function is called. This might be a typo, a missing operator, or an unescaped
string.

Message

SyntaxError: missing ) after argument list (V8-based & Firefox)
SyntaxError: Unexpected identifier 'x'. Expected ')' to end an argument list. (Safari)

Error type

What went wrong?

There is an error with how a function is called. This might be a typo, a missing
operator, or an unescaped string, for example.

Examples

Because there is no «+» operator to concatenate the string, JavaScript expects the
argument for the log function to be just "PI: ". In that case,
it should be terminated by a closing parenthesis.

console.log('PI: ' Math.PI);
// SyntaxError: missing ) after argument list

You can correct the log call by adding the + operator:

console.log('PI: ' + Math.PI);
// "PI: 3.141592653589793"

Alternatively, you can consider using a template literal, or take advantage of the fact that console.log accepts multiple parameters:

console.log(`PI: ${Math.PI}`);
console.log('PI: ', Math.PI);

Unterminated strings

console.log('"Java" + "Script" = "' + 'Java' + 'Script");
// SyntaxError: missing ) after argument list

Here JavaScript thinks that you meant to have ); inside the string and
ignores it, and it ends up not knowing that you meant the ); to end the
function console.log. To fix this, we could put a' after the
«Script» string:

console.log('"Java" + "Script" = "' + 'Java' + 'Script"');
// '"Java" + "Script" = "JavaScript"'

Что делать с ошибкой Uncaught SyntaxError: missing ) after argument list

Здесь сложно дать какую-то общую инструкцию, потому что каждый раз всё индивидуально и дело в нюансах, но мы попробуем.

На всякий случай действительно проверьте, не потерялась ли у вас закрывающая скобка. Маловероятно, но всё-таки.
Проверьте код на опечатки. Если пропустить букву в команде, то браузер может воспринимать её как новую функцию с кучей параметров, после которых должна всё-таки быть закрывающая скобка.
Посмотрите, правильно ли вы используете параметры при вызове, нужны ли внутри точки, запятые или другие скобки.
Если есть кавычки внутри кавычек — используйте разные кавычки для внутреннего и внешнего, например так: " Привет, это журнал 'Код' ".
Посчитайте, все ли параметры вы передаёте при вызове. Возможно, вы пытаетесь передать в функцию что-то лишнее, например, три параметра вместо двух.

Попробуйте сами. Найдите ошибки в этих фрагментах кода:

$(document).ready(function () {
  $("#anim").parents().eq(1).hover(
    function () {
      $(this).addClass('animated bounce');
    },
    function () {
      $(this).removeClass('animated bounce');
    },
    function () {
      $(this).css('animation-duration', 3s);   // ❌ говорит, что тут ошибка
    });
});

$.each(elements, fucntion(index, val){  // ❌ говорит, что тут ошибка
  console.log(index);
  console.log(val);
});

I am getting the syntax error:

SyntaxError: missing ) after argument list

From this jQuery code:

$('#contentData').append(
  "<div class='media'><div class='media-body'><h4 class='media-heading'>" + 
  v.Name + "</h4><p>" + v.Description + "</p><a class='btn' href='" + 
  type + "'  onclick="(canLaunch('" + v.LibraryItemId + " '))">
  View &raquo;
  </a></div></div>")

What kinds of mistakes produce this Javascript Syntax error?

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

$('#contentData').append("<div class='media'><div class='media-body'><h4 class='media-heading'>" + v.Name + "</h4><p>" + v.Description + "</p><a class='btn' href='" + type + "'  onclick="(canLaunch('" + v.LibraryItemId + " '))">View &raquo;</a></div></div>")

How to reproduce this error:

SyntaxError: missing ) after argument list

This code produces the error:

<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:

<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.

For me, once there was a mistake in spelling of function

For e.g. instead of

$(document).ready(function(){

});

I wrote

$(document).ready(funciton(){

});

So keep that also in check

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.

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.

<%= 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 :

SyntaxError: missing ) after argument list in /home/ubuntu/workspace/RESTful/RESTfulBlogApp/views/index.ejs while compiling ejs

How I fixed it : I removed «=» in the include statements at the top and the bottom and it worked fine.

SyntaxError: missing ) after argument list.

the issue also may occur if you pass string directly without a single or double quote.

$('#contentData').append("<div class='media'><div class='media-body'><a class='btn' href='" + type + "'  onclick="(canLaunch(' + v.LibraryItemName +  '))">View &raquo;</a></div></div>").

so always keep the habit to pass in a quote like

 onclick="(canLaunch('' + v.LibraryItemName  + ''))"

use:

my_function({width:12});

Instead of:

my_function(width:12);

Sometimes, we may run into the ‘SyntaxError: missing ) after argument list’ when we’re developing JavaScript apps.

In this article, we’ll look at how to fix the ‘SyntaxError: missing ) after argument list’ when we’re developing JavaScript apps.

Fix the ‘SyntaxError: missing ) after argument list’ When Developing JavaScript Apps

To fix the ‘SyntaxError: missing ) after argument list’ when we’re developing JavaScript apps, we should make sure we have corresponding closing parentheses for each opening parentheses in our JavaScript code.

On Edge, the error message for this error is SyntaxError: Expected ')'.

And on Firefox, the error message for this error is SyntaxError: missing ) after argument list.

For instance, if we write:

console.log('PI: ' Math.PI);

then the error will be thrown because we’re missing the comma between 'PI: ' and Math.PI.

To fix this, we write:

console.log('PI: ',  Math.PI);

The error will also be thrown if we have unterminated strings.

For instance, if we write:

console.log('"Java"' + 'Java' + 'Script");

then we’ll get the error since we don’t have a closing single quote in the 'Script" string.

To fix this, we write:

console.log('"Java"' + 'Java' + 'Script"');

Conclusion

On Edge, the error message for this error is SyntaxError: Expected ')'.

And on Firefox, the error message for this error is SyntaxError: missing ) after argument list.
