I am typing in a v simple example into sublime text. I have the SublimeLinter and JSLint plugins installed, but am getting the following error:
#1 Expected '(end)' and instead saw '<!'.
The code is a simple HTML file, which may be my problem. I don't know.
The code is as follows:
<!doctype html>
<html>
<head>
<title></title>
</head>
<body>
</body>
</html>
If it is true that either linting plugin is causing this error what should I do?
The error is generated by JSLint. By default, it runs on files with extensions .js, .json, .html, .sass, and .less. To prevent the error without disabling or removing JSLint, try removing HTML files from this list.
To do this, open JSLint.sublime-settings. Around line 35 you should see the following property.
,"filename_filter": "(\\.js|\\.json|\\.html|\\.sass|\\.less|\\.html)$"
Erase both |\\.html entries so that you're left with this.
,"filename_filter": "(\\.js|\\.json|\\.sass|\\.less)$"
Save your file. You may need to restart Sublime Text. Also note that you can still run JSLint on an HTML file using the following shortcut.

My javascript was working properly and then all of the sudden it wasn't. Chrome give me the Uncaught SyntaxError: Unexpected token ILLEGAL error on line 1 of my JS file called para2.js. I removed script from the file except for the following and I still get the error:
$( window ).ready(function() {
});
My jQuery file is included in the head of my document:
<script src="../shared/jquery.js" type="text/javascript"></script>
<script src="js/para2.js" type="text/javascript"></script>
When I look at my js file in Chrome developer tools on the Sources tab, it displays the script in Chinese:
兪敵祲搨捯浵湥⥴爮慥祤昨湵瑣潩⡮笩⥽
When I view the source of the js file, it looks fine. I have read similar posts that say copy and pasting from JSFiddle can include some hidden characters that may cause it, but I have started from scratch writing this file from a blank text file and copy and pasting nothing. It is strange that it was working and now it is not. Did my server get hacked or something? And help is appreciated.
You should use the charset attribute to indicate which charset you are using.
<script src="../shared/jquery.js" type="text/javascript" charset="UTF-8">
I had the same problem with jquery-1.5.1.min.js. Chrome kept evaluating it as Chinese (scripts worked fine in IE). I finally solved the problem by re-encoding the .js files using "convert to UTF-8" in Notepad++. Note, not UTF-8 without BOM, but UTF-8.
for some reason when i try to load jquery via cdn, it works perfectly
script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"
however, when i try to load it using the local files, it does not work
script type="text/javascript" src="javascripts/jquery-1.11.2.min.js"
and displays this error:
Uncaught SyntaxError: Unexpected token < jquery-1.11.2.min.js:1
i must say that my server is running on node.js
it seems you have syntax error with your tag.
try this.
<script type="text/javascript" src="javascripts/jquery-1.11.2.min.js"></script>
It seems as though there is an error occurring inside jquery-1.11.2.min.js. Not in the document which contains the script tag. So, the question is: why does your local copy of jquery-1.11.2.min.js contain a <? The answer is that it most likely doesn't. The request for jquery-1.11.2.min.js is probably resulting in a HTML response, which the browser attempts to load as JavaScript, and fails on the first character. Ensure that javascripts/jquery-1.11.2.min.js is the correct path to your JavaScript file.
It can be shown that this is the case because a SyntaxError is a JavaScript error. MDN says the following (emphasis mine):
A SyntaxError is thrown when the JavaScript engine encounters tokens or token order that does not conform to the syntax of the language when parsing code.
So, the error is being thrown by the JavaScript engine, which means that the browser is actually trying to load a script file. As you can see from the error message, the error is thrown at jquery-1.11.2.min.js:1, which is line one of jquery-1.11.2.min.js. You can reproduce the same error message using the following code saved in a file named foo.html:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="foo.html"></script>
</head>
<body></body>
</html>
Alternatively, you can view a demonstration of equivalent code here (check your console).
I'm using Notepad++ to write a simple JavaScript program. I tried to run it with Firefox but the page was blank. I saved it as a HTML file but still nothing. Where am I going wrong?
Here is the code:
<!DOCTYPE html>
<html>
<head>
<title>Exercise 1 </title>
</head>
<body>
<script type = “text/javascript”>
var myName = "type your name!!";
document.write("Hello World");
</script>
</body>
</html>
These look like left quote/right quote characters:
<script type = “text/javascript”>
^ ^
They should be regular double-quote characters <script type="text/javascript">, or you can leave them out entirely, as all browsers default to using Javascript:
<script>
</script>
Additionally, it is not recommended to use document.write any longer. You should use some of the DOM manipulation methods available instead.
As pointed out you are using the wrong type of quotes. Note that you can download jshint for notepad++ which can be very useful as it catches these types of bugs before you run. At the time of writing this answer, you can get it from sourceforge here. It includes jslint and jshint.
JSHint is a community-driven tool to detect errors and potential
problems in JavaScript code and to enforce your team's coding
conventions. It is very flexible so you can easily adjust it to your
particular coding guidelines and the environment you expect your code
to execute in.
I've just downloaded D3.js from d3js.org (link to zip file), unzipped it, and referenced it in the following HTML page:
<html>
<head>
<title>D3 Sandbox</title>
<style>
</head>
<body>
<script src="/d3.v3.js"></script>
</body>
</html>
But when I load this page, my console (in Chrome) is giving me this error:
Uncaught SyntaxError: Unexpected token ILLEGAL: line 2
It doesn't like the pi and e symbols at the start of the file. Errrr... what can I do about this? I am serving the file with python's SimpleHTTPServer.
Update: yes I know I can just link to a CDN version, but I would prefer to serve the file locally.
Try specifying the UTF-8 charset on the HTML host document :
<meta http-equiv="content-type" content="text/html; charset=UTF8">
D3 contains UTF-8 symbols (like π) invalids in non-UTF8 documents.
That sounds like a problem with encoding. I recommend The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!). Despite the somewhat condescending title, it contains some very useful information. Specifically, it sounds like your server is serving the d3.v3.js file with the wrong encoding.
Add 'charset="utf-8"'
<script src="/d3.v3.js" charset="utf-8"></script>
I tried setting the charset in the doc and in the script tag itself, but Chrome doesn't seem to care. Not sure if i'm doing something wrong.
I did find success by running it through uglify with the --ascii-only option first.
UPDATE: Turns out my View->Encoding setting in Chrome was not on Auto-Detect, but some Western encoding. Not sure why, but changing that resolved the problem. Ridiculous that that setting would trump a charset property right on the script tag. Considering that users might be in the same situation and not be able to figure it out, i'll still be using uglify to ensure success.
Check if you have a plus sign between all of your string concatenations, if you do not this error will be generated.
I am getting the following error:
Microsoft JScript runtime error: 'Sys'
is undefined
While trying to execute:
<head id="Head1" runat="server">
<title>Untitled Page</title>
<script language="javascript" type="text/javascript">
//ERROR IN THIS LINE!!!
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(onUpdated());
function onUpdated() {
// get the update progress div
var pnlPopup = $get("div2");
// make it invisible
}
</script>
</head>
Ensure you have a Scriptmanager on the page and the script is below the scriptmanager. Maybe try to put your script tag into body and see what happens.
I don't know how you can fix that that its not in the body, but maybe there is a callback from Sys when its loaded
You don't need brackets to tell which function is neeeded:
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(onUpdated);
If that is your full code, then the problem is that the Microsoft AJAX libraries aren't being included. If it isn't your full code, then you need to post more as it's a little hard to get beyond the fact that the library isn't included. Somewhere in your file -- prior to the line you are having problems with you need to have a javascript include like:
<script type="text/javascript" src="/scripts/MicrosoftAjax.js" />
As well as probably a few others.
Note: I'm talking about the generated source. Showing more complete markup would probably also suffice.
I'm a bit late to the discussion here, but a simple solution is to create a "ASP.NET AJAX-Enabled Web Site" in Visual Studio and then merge the web.config from that site with your existing site.
In this way you get all the configuration you need without having to carefully read through a lot of docs. Speed is of the essence and all that :)
You can fix this issue by setting the EnableCDN property to "true".refer this link
I had the same issue , after all findings I found that the required script files ("MicrosoftAjax.js", "WebForms.js","jquery", "bootstrap" etc..) were not loaded properly which was causing me 3 errors "Sys' is undefined", "webform_docallback is undefined" and "webform_initcallback' is undefined", my actual problem was I had reference to these files which where not included in my propject, my bad I have not noticed it, I have tried all the possible solutions from the internet before I really found that my js files were not included and thats the reason its not loaded properly.
Hope this helps..
