Hey there,

when I try to include JavaScript into my template, it behaves weirdly. Sometimes it works sometimes I get:

"SyntaxError: expected expression, got '<'".

As soon as I remove the JavaScript includes, it works again.
Anyone have an idea?

Code:
        $this->view = new Smarty();
        $this->view->setCompileDir(__DIR__ . '/../views/smarty-compile');
        $this->view->setTemplateDir(__DIR__ . '/../views');
        $this->view->display("login/login.tpl");


login.tpl

Code:
<!DOCTYPE HTML>
<html>
<head>
    {literal}
    <script src='app/libs/jquery-3.2.1.js'></script>
    {/literal}
    <meta charset="UTF-8">
</head>
<body>
    <form id="login">
        <input id="usr" type="text" value="username"><br>
        <input id="pw" type="password" value="password"><br>
        <input type="submit">
    </form>
{literal}
    <script src='app/js/login.js'></script>
{/literal}

</body>
</html>
[/code]


Thanks!

Must be "<!DOCTYPE html>".
XML doctype declaration is case-sensitive.

{/literal}

{literal} here is useless.

{/literal}

Move this include into the header and use either body onload, or form change events.

I see nothing in your template that could prompt the issue, which make me believe you are not reading your error messages correctly and not paying attention to your JS code.

If there is more to this code than what was posted, and if the error message is coming from the browser's javascript engine and is shown in the javascript error console, as opposed to PHP throwing the error and showing it in the document window, then there may a situation like this:
Code:
var x = <?php echo $data ?>

This is caused by the PHP code not being executed.

So, let's have a look at login.js (we can assume jquery.js is fine).
