I feel kinda silly asking this question but I have tried everything I know and even consulted the api docs all to no avail.
My question is how to fix:
Uncaught TypeError: Cannot read property 'v0' of null
What I am doing is compiling a dart based chrome app with dart2js using dart-sdk version 1.10 I have also tried dart-sdk version 1.9 with the same result.
All of my code is located at:
https://github.com/dragonloverlord/Pages
I am building my project in pycharm community edition 4.5 with the dart plugin if that matters.
I have tried using 'build mode=debug' but no different message was given I had the source maps set up as well but nothing changed.
The os that I am building on is linux ubuntu 15.04
I have found the solution to the issue and it's actually very simple!
All you have to do is move the dart scripts to the body of the document like so:
<!DOCTYPE html>
<html id="html">
<head>
<meta charset="utf-8">
<title>Pages</title>
<link rel="stylesheet" type="text/css" href="./css/index.css">
</head>
<body id="body">
<div id="menubar">
<button class="float-left" id="add-page" type="button">Add Page</button>
</div>
<div id="main-container">
</div>
<script src="packages/chrome/bootstrap.js" type="text/javascript" defer></script>
<script src="main.dart" type="application/dart"></script>
</body>
</html>
Compared to having them in the head of the document like so:
<!DOCTYPE html>
<html id="html">
<head>
<meta charset="utf-8">
<title>Pages</title>
<link rel="stylesheet" type="text/css" href="./css/index.css">
<script src="packages/chrome/bootstrap.js" type="text/javascript" defer></script>
<script src="main.dart" type="application/dart"></script>
</head>
<body id="body">
<div id="menubar">
<button class="float-left" id="add-page" type="button">Add Page</button>
</div>
<div id="main-container">
</div>
</body>
</html>
A very simple fix that is often forgotten!
Also adding defer to the dart script will fix the issue like so:
<!DOCTYPE html>
<html id="html">
<head>
<meta charset="utf-8">
<title>Pages</title>
<link rel="stylesheet" type="text/css" href="./css/index.css">
<script src="packages/chrome/bootstrap.js" type="text/javascript" defer></script>
<script src="main.dart" type="application/dart" defer></script>
</head>
<body id="body">
<div id="menubar">
<button class="float-left" id="add-page" type="button">Add Page</button>
</div>
<div id="main-container">
</div>
</body>
</html>

I am have ASP.Net MVC5 Web application & in need to integrate Angular5 app with it.
Referring to the below link, I am doing the integration.
Integrate Angular 5 with ASP.NET MVC 5
This command can only be run inside of a CLI project
When running the standalone Angular5 app, it runs fine. but when the same component integrating with Razor view, I am getting the below error.
The selector "app-root" did not match any elements
It's been more than a day that I spent on fixing this.
Index.cshtml looks as below.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Home Page - My ASP.NET Application</title>
<link href="/bundles/styles.bundle.js" rel="stylesheet"/>
<script src="/bundles/inline.bundle.js"></script>
<script src="/bundles/polyfills.bundle.js"></script>
<script src="/bundles/scripts.bundle.js"></script>
<script src="/bundles/vendor.bundle.js"></script>
<script src="/bundles/main.bundle.js"></script>
</head>
<body>
<div class="navbar navbar-inverse navbar-fixed-top">
<div class="container">
<div class="container body-content">
<div class="row">
<app-root></app-root>
</div>
<hr />
<footer>
<p>© 2018 - My ASP.NET Application</p>
</footer>
</div>
</body>
</html>
Thanks.
OMG!!
Two steps fixed this big head breaking issue:-
added <base href="/"> in head section
moved the bundles in the bottom of page i.e., just before the closing body tag
#Styles.Render("~/Content/Styles")
#Scripts.Render("~/Scripts/Bundles")
</body>
Hope this helps!!
Keep the code in Index.cshtml as below. It should work.
<html>
<head>
<base href="/" />
</head>
<body>
<app-root></app-root>
<script type="text/javascript" src="~/Scripts/lib/runtime.js"></script>
<script type="text/javascript" src="~/Scripts/lib/polyfills.js"></script>
<script type="text/javascript" src="~/Scripts/lib/vendor.js"></script>
<script type="text/javascript" src="~/Scripts/lib/main.js"></script>
</body>
</html>
I had this problem, but then realised the cause was that I hadn't wrapped my static script references in the #section scripts tag as per the demo, and they were above the app-root tag. The layout needs to write the scripts into the page after the app-root tag. If the tag appears before the references, you'll get that error message.
I have setup Angular 2 with ASP.NET core, using:
dotnet new --install Microsoft.AspNetCore.SpaTemplates::*
I followed the standard setup but the App.component.html is duplicating the html and body tags.
When Pressing Control U (to view source) the html looks like:
<html>
<head>
....
</head>
<body>
<app>
<html>
<head>
<style>
...
</style>
</head>
</app>
</body>
</html>
</app>
...
</body>
</html>
redacted
None of my components have html or body tags in them. the only one that has html or body tag is the initial page
My _Layout.cshtml html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>#ViewData["Title"] - HotSnail</title>
<base href="/" />
<script src="~/content/modules/jquery/jquery-3.2.1.min.js"></script>
<script src="~/content/modules/bootstrap-3.3.7-dist/js/bootstrap.js"></script>
<link rel="stylesheet" href="~/dist/vendor.css" asp-append-version="true" />
<link href="~/content/modules/font-awesome-4.7.0/css/font-awesome.css" rel="stylesheet" />
<link href="~/content/modules/animate/animate.css" rel="stylesheet" />
<link href="~/content/global.css" rel="stylesheet" />
</head>
<body>
#RenderBody()
#RenderSection("scripts", required: false)
</body>
</html>
My Index.cshtml
<script src="~/dist/vendor.js" asp-append-version="true"></script>
#section scripts {
<script src="~/dist/main-client.js" asp-append-version="true"></script>
}
The above code is what should be served, now the first bit of angular should be the app.component
app.component.html
<ribbon></ribbon>
<div id="content">
<router-outlet></router-outlet>
</div>
ribbon.component.html:
<div id="ribbon">
<span class="ribbon-button-alignment">
<span id="refresh" class="btn btn-ribbon" data-action="resetWidgets" data-title="refresh" rel="tooltip" data-placement="bottom" data-original-title="<i class='text-warning fa fa-warning'></i> Warning! This will reset all your widget settings." data-html="true" data-reset-msg="Would you like to RESET all your saved widgets and clear LocalStorage?"><i class="fa fa-refresh"></i></span>
</span>
<!-- breadcrumb -->
<ol class="breadcrumb"><li>Home</li><li>Outlook</li><li>Inbox</li></ol>
</div>
This is all the components that should be injected on the first page
UPDATE*
So I have done some more research and it seems to be a known bug. As it says here:
https://github.com/aspnet/JavaScriptServices/issues/662
I cant quiet figure out their hacky solution
Here is hacky code that fixes this:
return requestZone.run>(() =>
platform.serializeModule(AppModule)).then(html => { resolve({ html:
html.slice(27, html.length - 14).replace('', '') }); },
reject);
Also in index.cshtml I advice changing app to div because we already
have app tag returned from Universal.
Loading...
I'm not sure where that code would go..
UPDATE
This also happens in the DEFAULT project created when doing
dotnet new angular
Does anyone know who maintains these templates as I'd like to post a bug with the development team
Same problem for angular 5.
I fixed it like in suggestion from last comment on https://github.com/aspnet/JavaScriptServices/issues/662 (last comment by salarcode):
boot.server.ts file change the code to this:
resolve({
html: (() => {
let apphtml = state.renderToString();
apphtml = apphtml.replace('<html><head><style>', '<style>').replace('</head><body><app', '<app').replace('</app></body></html>', '</app>');
return apphtml;
})()});
First of all I have seen every single question stating the same issue on Stack and non of them applied to mine
I was building my First PhoneGap App and i want to use jQueryMobile libraries
anyways, the JQuery Styles is not working properly,

<script type="text/javascript">
app.initialize();
</script>
</body>
</html>
And the results are
as you can see the button inline and corner all attributes worked fine but still that is not the expectedP
You didnt reference them properly
Remove the dot. I following the folder structure of where your css files are, your java script files should be here /js not ./js
So reference like this
[code]
[/code]
Getting this error $(..).tabs not a function.
here are my imports

<script type="text/javascript" src="js/jquery-ui-1.10.4.js"></script>
<script type="text/javascript" src="js/home.js"></script>
Can you help debugging that.

This was working until today, i don't know why it stopped working & console is throwing me error tabs is not defined function
The structure would need to look like this:
page.html
-js (folder)
--jquery-2.1.1.js
--jquery-ui-1.10.4.js
The html file would then have the references as you've show above:
<link rel="stylesheet" href="css/jquery-ui-1.10.4.css" type="text/css"></link>
<script type="text/javascript" src="js/jquery-2.1.1.js"></script>
<script type="text/javascript" src="js/jquery-ui-1.10.4.js"></script>
<script type="text/javascript" src="js/home.js"></script>
You could also use chrome dev tools (F12) to check if the resources have loaded
NOTE: if you're home.js is using any jquery functionality, this file should always be added after the jquery files.
EDIT: based on comment
make sure you're using it like $("#name").tabs(); and not $("#name").tabs;
I had included jquery.js in one of the included jsp page which was causing the issue & the browser was not able to load the jquery files.
I have main html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=0" />
<title>Home</title>
<link rel="stylesheet" href="js/jquery.mobile-1.2.0/jquery.mobile-1.2.0.css" type="text/css" media="screen" title="no title" charset="utf-8" />
<link rel="stylesheet" href="css/Home.css" type="text/css" media="screen" title="no title" charset="utf-8" />
<link rel="stylesheet" href="css/theme-addon.css" type="text/css" media="screen" title="no title" charset="utf-8" />
<script src="js/jquery-1.7.2.min.js" type="text/javascript" charset="utf-8"></script>
<script src="js/jquery.mobile-1.2.0/jquery.mobile-1.2.0.min.js" type="text/javascript" charset="utf-8"></script>
</head>
<body id="content" style="display: none">
<div data-role="page" id="homePage">
<div data-role="header"><div class="ui-title">Home</div></div>
<div data-role="content" style="text-align: center">
<a data-role="button" id="login" class="fullWidth">Login</a>
</div>
</div>
<script src="js/initOptions.js"></script>
<script src="js/Home.js" type="text/javascript" charset="utf-8"></script>
<script src="js/messages.js"></script>
</body>
Then in Home.js:
// Worklight comes with the jQuery framework bundled inside. If you do not want to use it, please comment out the line below.
window.$ = window.jQuery = WLJQ;
function wlCommonInit(){
// Common initialization code goes here
}
$("#homePage").live('pagecreate', function(event,ui) {
$('#login').click(function(){
$.mobile.changePage($('#nextPage.html'));
});
});
When I tap on login button, it gives error $.mobile is undefined on this line:
$.mobile.changePage($('#nextPage.html'));
Is there anyone can give insight what's wrong with my code? I believe I do the right things? In addition, I use 5.0.2.407-developer-edition Worklight version.
Finally I solved this issue by:
<script src="js/jquery-1.9.1.min.js" type="text/javascript" charset="utf-8"></script>
<script>
var jq = jQuery.noConflict();
</script>
<script src="js/jquery.mobile-1.3.1/jquery.mobile-1.3.1.min.js" type="text/javascript" charset="utf-8"></script>
and later in js:
jq.mobile.changePage("the.html");
instead of
$.mobile.changePage("the.html");
Worklight is already bundled with jQuery, so you shouldn't add it a second time as you did at the bottom of the HTML. Also, you shouldn't place it at the bottom anyway, rather in the HEAD - remove that line.
Additionally, move the reference to jQuery Mobile to the HEAD a as well.
Using Worklight 5.0.6.1 (the latest version, which you seem not to use) and jQuery Mobile 1.3.1, I created a new project and application, and modified the HTML as follows:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8">
<title>testapp</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=0">
<link rel="shortcut icon" href="images/favicon.png">
<link rel="apple-touch-icon" href="images/apple-touch-icon.png">
<link rel="stylesheet" href="css/testapp.css">
<script src="jqueryMobile/jquery.mobile-1.3.1.min.css"></script>
<script src="jqueryMobile/jquery.mobile-1.3.1.min.js"></script>
<script>window.$ = window.jQuery = WLJQ;</script>
</head>
<body id="content" style="display: none;">
<div data-role="page">
testapp
</div>
<script src="js/initOptions.js"></script>
<script src="js/testapp.js"></script>
<script src="js/messages.js"></script>
</body>
</html>
I place the minified .css and .js files in a folder, and referenced them inside the HEAD element.
I added inside the BODY element.
Build All and Deploy
Preview via Worklight Console
Works...
I suggest you start small like the above (including using the latest versions of Worklight and jQuery Mobile), and build on that (working) foundation).
You can get the latest version of Worklight from the Eclipse Marketplace (in Eclipse, look at the Help menu >> Marketplace).
