How can I test in Cypress that the background image I get is working and the image is loaded properly in the preview?
The best solution I can think of is to test the URL of the background image with a cy.request().
It's a bit involved, but I can't see anything on the page that indicates a failed load for the image.
For example, this simple page:
<html>
<head>
<style>
body {
background-image: url("https://www.w3schools.com/cssref/paper.gif");
background-color: #cccccc;
}
</style>
</head>
<body>
<h1>The background-image Property</h1>
<p>Hello World!</p>
</body>
</html>
Tests like this,
cy.get('body')
.should('be.visible')
.and('have.css', 'background-image', 'url("https://www.w3schools.com/cssref/paper.gif")')
.then($el => {
const url = $el.css('background-image').match(/url\("(.*)"\)/)[1]
cy.request({url, failOnStatusCode: false})
.its('status')
.should('eq', 200)
})
cy.get('yourSelector').should('have.attr', 'height', 'yourHeight');
or
cy.get('yourSelector').should('have.css', 'background-image');

Very simple question, can I use functions like await inside paperjs?
I can chain together a lot of .then's and it's going fine, but as soon as I add await in front of it I get the error
SyntaxError: Unexpected token (4:22)
Please tell me they didn't make it so that I have to start wrapping everything in insanely long chains in order to integrate functions like fetch into paperjs. Below my code:
<script type="text/paperscript" canvas="myCanvas">
getCollectionList = async function() {
var collectionlist = [];
collectionlist = await fetch('/api/graph/<%= database %>');
console.log(collectionlist);
}
getCollectionList();
</script>
<canvas id="myCanvas" resize></canvas>
Your are writing your code as PaperScript which implies that Paper.js uses a JavaScript parser to parse it and apply some transformations to it.
The problem is that by default, the JavaScript parser used by Paper.js does not support ES6 features.
You have to load a more recent version of the parser (Acorn) before loading Paper.js to solve your issue.
See my answer to an analog issue here for more details.

Using paperjs if I rotate p.view.rotate(update.deg); it is working fine with out issue.
If I refresh the page and call the above function p.view.rotate(update.deg); onload then the view is different. it is displaying a slight zoom.
default image rotation
After reloading the page I am rotating p.view with the previous value. then it is displaying as
Here is my js file

I was not able to run your code but I would suggest, for an easier project state preservation, that you use transformations (scale, rotation, ...) through layer rather than through view.
That would allow you to easily export/import your project whithout having to manually restore state by calling view.rotate() like methods on window reload.
Here is a fiddle demonstrating the solution.
It simulates window reload by exporting/importing a project from one canvas to another empty one.

i want that when u put mouse on text it show image in div i m trying to do it but it not working.
Forget javascript for this one! CSS is the answer. Put a hover state on ID:img1 and the images inside the div (if u don't do the latter, mousing over the images will cancel out the div mouse over. So it will look like this (not inline styles due to mouse over states declaration):
#img1 {
Background-image: none;
}
#img1:hover, img1:hover img {
Background-image: url(your URL);
}
You could change the IDs to classes, so the CSS can be reused and keep the IDs for coding (javascript etc)
Has anyone had any luck with this?
I copied and pasted the exact example code here http://www.jqplot.com/deploy/dist/examples/barTest.html into my text editor. I added all the .js files and .css file required. when I run the page in any browser, I am not seeing the bars or the animation. I have looked at the source code on the above URL as well to see how it works. Could someone tell me why I can the animated bar chart on the URL but not from my desktop? What's different? Here is the exact code I copied:
<html>

here is what I see in the browser after running that code:
Thanks
For anyone interested, I've found the answer. The example code taken from the barchart.html page in my post doesn't appear to need the conditional syntax (below) in order to animate the bars:
$.jqplot.config.enablePlugins = true;
// Only animate if we're not using excanvas (not in IE 7 or IE 8)..
animate: !$.jqplot.use_excanvas,
From the animate example on the examples page , the following code will do the trick:
animate: true,
// Will animate plot on calls to plot1.replot({resetAxes:true})
animateReplot: true,
I read the entire documentation and was doing a lot of playing around with the code. Eventually, I got to the full "examples" page (not the few listed on the tests and examples page which I initially viewed since it was listed first in the documentation). I really wanted to understand the plugin code since the developer took so much time to really provide a ton of info, comments and updates to his code base.
I try a simple css3 media queries that will change background color when I change the browser to 480px width. It works fine when i put the files on my site, here: http://www.kangtanto.com/css3/ . But when I try the same files on my other site, with https, the media queries just won't work, the background color won't change when I change my browser size to 480px width. it is on my other site at https://dosenjaga.eepis-its.edu/home.html
this is my html code:
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css" />
<link rel="stylesheet" type="text/css" media="only screen and (max-width:480px)" href="css3.css" />
</head>
<body>
<div id="wrapper">
<div id="header">
<h1>Ini hanya mencoba saja lho</h1>
</div>
<div id="content">
Adding the specific code for devices inline might be a good way to use media queries if
you only need to make a few changes, however if your stylesheet contains a lot of
overwriting or you want to completely separate the styles shown to desktop browsers and those used for small screen devices, then linking in a different stylesheet will enable you to keep the CSS separate.
</div>
</div>
</body>
</html>
and this is my style.css file. On my other site I use style2.css, because there is a file with the same name on my server, so I gave it other name but the code is the same.
div#wrapper { width: 800px;}
div#header{
background-image:url(media_queries.png);
height: 93px;
position:relative;
}
div#header h1{
font-size:140%;
}
#content{
float:none;
width:100%;
background-color:#CCC;
}
#navigation{
float:none;
width:auto;
}
and this is my css3.css code
#media only screen and (max-width:480px){
div#wrapper { width: 400px;}
div#header{
background-image:url(media_queries.png);
height: 93px;
position:relative;
}
div#header h1{
font-size:140%;
}
#content{
float:none;
width:100%;
background-color:#8787C1;
}
#navigation{
float:none;
width:auto;
}
}
Thanks,
It is the problem of older versions of IE not the https, CSS3 is not supported in less then IE9. in IE9 it is working fine.
It's solved!!! I need to delete all my browser history by pressing Shift+ctrl+del on my fire
