In this tutorial it says:
"Opening the spec runner in a web browser will give the expected outcome:"
But does not mention how to do it. How can I do it?
Example code:
var My = {
sqrt: function(x) {
if (x < ) throw new Error("sqrt can't work on negative number");
return Math.exp(Math.log(x)/2);
}
};
Test code:
describe("sqrt", function() {
it("should compute the square root of 4 as 2", function() {
expect(My.sqrt(4)).toEqual(2);
});
});
There should be a SpecRunner.html file that references jasmine, your code, and your spec files. Looks something like this:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Jasmine Spec Runner v2.0.2</title>
<link rel="shortcut icon" type="image/png" href="libs/jasmine-2.0.2/jasmine_favicon.png">
<link rel="stylesheet" type="text/css" href="libs/jasmine-2.0.2/jasmine.css">

I'm just trying to run this code I got from Vtk.js documentation examples:
<!DOCTYPE html>
<html>
<head>
<title>vtk</title>
</head>
<body>
<script type="text/javascript" src="https://unpkg.com/#babel/polyfill#7.0.0/dist/polyfill.js"></script>
<script type="text/javascript" src="https://unpkg.com/vtk.js"></script>
<script type="text/javascript">
import 'vtk.js/Sources/favicon';
import vtkActor from 'vtk.js/Sources/Rendering/Core/Actor';
import vtkFullScreenRenderWindow from 'vtk.js/Sources/Rendering/Misc/FullScreenRenderWindow';
import vtkMapper from 'vtk.js/Sources/Rendering/Core/Mapper';
import vtkSTLReader from 'vtk.js/Sources/IO/Geometry/STLReader';
</script>
</body>
</html>
But I got a blank page and the console shows me the error:
SyntaxError: Unexpected string literal 'vtk.js/Sources/favicon.'
import call expects exactly one argument. I think my error comes from the my first import.
Thanks in advance
You can run vtk.js on a html page like this:
<!DOCTYPE html>
<html>
<body>
<script type="text/javascript" src="https://unpkg.com/#babel/polyfill#7.0.0/dist/polyfill.js"></script>
<script type="text/javascript" src="https://unpkg.com/vtk.js"></script>
<script type="text/javascript">
var fullScreenRenderer = vtk.Rendering.Misc.vtkFullScreenRenderWindow.newInstance();
var actor = vtk.Rendering.Core.vtkActor.newInstance();
var mapper = vtk.Rendering.Core.vtkMapper.newInstance();
var stlReader = vtk.IO.Geometry.vtkSTLReader.newInstance();
</script>
</body>

I'm trying to give my html an css inline style. But this style gets ignored.
This is the HTML string that I'm using for webView.loadHTMLString(htmlBelow, baseURL: Bundle.main.bundleURL)
let fontsize = 16 //This is an dynamic variable
<!DOCTYPE html>
<html lang=\"en\">
<head>
<meta charset=\"UTF-8\">
<meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\">
<meta http-equiv=\"X-UA-Compatible\"content=\"ie=edge\">
<title>Document</title>
<style>
​html {
font-size:\(fontsize)px; */THIS DOESN'T WORK/*
}
</style>
<link rel=\"stylesheet\" href=\"\style.css\">
<script src=\"jquery-3.4.1.min.js\"></script>
<script src=\"script.js\"></script>
</head>
<body>
<div class=\ "sqr-tree-level\"> \(restOfHtml) </div>
</body>
</html>
I'm trying to set the fontsize dynamically.
When I change the font-size in my css file it works, but I want to set it dynamically. That's why I wanna do it like this.
This is how my document.head.innerHTML looks like
For future reference the fix here was to put the styling in to the <body> tag instead of in the head <style> tag.
<body style=\"font-size:\(fontsize)px;\">
I have an angular 2 app that I built using the angular cli generator: https://github.com/EdmundMai/angular-2-playing
This is the generator: https://github.com/angular/angular-cli
I ran ng serve and now I have a page I can see when I visit http://localhost:4002
My dist/index.html file in the angular 2 app looks like this:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>AngularTwo</title>
<base href="/">
<script src="/ember-cli-live-reload.js" type="text/javascript"></script>

</script>

<script>
window.carbon.importComponents({ components: ['ct-button', 'ct-button/ct-button-link', 'ct-dialog', 'ct-progress'] });

In my rails view, I am trying to include these JS files:
<script src="http://localhost:4200/vendor/es6-shim/es6-shim.js"></script>
<script src="http://localhost:4200/vendor/reflect-metadata/Reflect.js"></script>
<script src="http://localhost:4200/vendor/systemjs/dist/system.src.js"></script>
<script src="http://localhost:4200/vendor/zone.js/dist/zone.js"></script>
<script src="http://localhost:4200/system-config.js"></script>
<script src="http://localhost:4200/main.js"></script>
However, it's not working and complaining that main.ts:1Uncaught ReferenceError: require is not defined
Is there a proper way of doing this?
You need to change the <base href="/"> tag (line 6) in the generated
dist/index.html
to <script>document.write('<base href="' + document.location + '" />');</script>
I followed these instructions for my app:
https://github.com/yeoman/generator-angular#readme
My Index (before build)
<!-- Place favicon.ico and apple-touch-icon.png in the root directory -->
<!-- build:css(.) styles/vendor.css -->
<!-- bower:css -->
<link rel="stylesheet" href="bower_components/bootstrap/dist/css/bootstrap.css" />
<!-- endbower -->
<!-- endbuild -->
<!-- build:css(.tmp) styles/app.css -->
<link href="app.less" type="text/css" rel="stylesheet/less">
<!-- endbuild -->
My dist Index (in text-editor)
<html ng-app="myApp"> <head> <meta charset="utf-8"> <title>Datavalidering</title> <meta name="description" content=""> <meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no"> <!-- Place favicon.ico and apple-touch-icon.png in the root directory --> <link rel="stylesheet" href="styles/vendor.2ac5f564.css"> <link rel="stylesheet" href="styles/app.d41d8cd9.css"> </head> <body>
Dist index (browser)
<head>

<meta name="description" content="">

<style type="text/css">body { display: none !important }</style></head>
<body>
The problem may be in gruntfile.js
http://plnkr.co/edit/r2hdhWY7olIw0pBHJ4VF?p=preview
Thank you in advance for your answers!
This happens because of (less.js):
// Simulate synchronous stylesheet loading by blocking page rendering
if (!options.async)
{
css = 'body { display: none !important }';
head = document.head || document.getElementsByTagName('head')[0];
style = document.createElement('style');
style.type = 'text/css';
if (style.styleSheet) {
style.styleSheet.cssText = css;
} else {
style.appendChild(document.createTextNode(css));
}
head.appendChild(style);
}
so, all you need to do is add this before less.js
<script>
less = {
async: true
}
</script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/less.js/2.6.1/less.min.js"></script>
I'm not using Angular, but had a similar problem where this <style type="text/css">body { display: none !important }</style> suddenly appears at the end of head tag, effectively renders the whole page to not displaying anything.
I found out that the culprit was less.js. Simply commenting the line fixes it.
I have found a solution and the culprit.
It comes from the "Jetpack".
This image shows the location of the code in WordPress Directory:
in my data_feed controller and bar action, there's only one line in bar.html.erb:
[1,2,3,4]
My expected output by requesting http://localhost:3000/data_feed/bar is just one line I wrote above.
However, rails help me add some html heads into that page, as below:
<!DOCTYPE html>
<html>
<head>
<title>Guustock</title>
<link href="/assets/application.css?body=1" media="all" rel="stylesheet" type="text/css" />
<link href="/assets/charts.css?body=1" media="all" rel="stylesheet" type="text/css" />
<link href="/assets/data_feed.css?body=1" media="all" rel="stylesheet" type="text/css" />
<link href="/assets/show.css?body=1" media="all" rel="stylesheet" type="text/css" />
<script src="/assets/jquery.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery_ujs.js?body=1" type="text/javascript"></script>

<script src="/assets/data_feed.js?body=1" type="text/javascript"></script>
<script src="/assets/show.js?body=1" type="text/javascript"></script>
<script src="/assets/application.js?body=1" type="text/javascript"></script>

<meta content="lhHWCW82xtqQ8fmgBZemDggL2DGJe+4chXM8MY1LKvs=" name="csrf-token" />
</head>
<body>
[1,2,3,4]
How can I avoid rails doing this?
Thanks!
Env:
linux mint 11.0
ruby 1.9.3 with rvm
rails 3.2.1
EDIT:
Actually I want to provide the json format data in this page as an ajax data source. So these heads will not helpful but break the data.
You're probably rendering within the layout (a view template, which lives in app/views/layouts/), which is the default. If you want to render an action without the layout, use something like
render :bar, :layout => false
in the appropriate action.
See also: http://guides.rubyonrails.org/layouts_and_rendering.html
EDIT:
Please see the documentation linked above. For JSON rendering, you might use this directly from the controller:
render :json => #product
or in your case
render :json => [1,2,3,4]
You could also use JSON view templates (for which you'll need to render again). Using a bar.html.erb template for json is not only tricky as you noticed, it will also produce the wrong content type headers.
