I was hoping not to asking you for help but here I am
I want to build a simple Chrome extension which marks all paid articles on the home page.
The JS in the medium-extension.js is working through a browser console when is triggered with a button which can be found in the HTML file.
The problem is that I am confused do I need background script, because when I try without one the extension does not work. Now I try without a content script and it still does not work.
I try to do it with one of them because I don't know how to create a connection between background and content scripts.
Here is the code:
manifest.js
{
"name": "Medium cleared",
"version": "1",
"description": "Lets's make Medium great again",
"manifest_version": 2,
"browser_action": {
"default_popup": "index.html"
},
"background": {
"scripts": ["medium-extension.js"],
"persistent": false
}
}
medium-extension.js
function clearMedium() {
Array.from(
document.querySelectorAll('article')
).forEach(el => {
let shouldHide = el.querySelectorAll('span.u-paddingLeft4').length;
if (shouldHide) {
el.style.background = "#FCBFB7";
}
});
Array.from(
document.querySelectorAll('li')
).forEach(el => {
let shouldHide = el.querySelectorAll('span.u-paddingLeft4').length;
if (shouldHide) {
el.style.background = "#FCBFB7";
}
});
Array.from(
document.querySelectorAll('.extremeHero-smallCard.extremeHero-smallCard1.js-trackedPost, .extremeHero-largeCard.js-trackedPost.uiScale.uiScale-ui--small.uiScale-caption--small, .extremeHero-smallCard.extremeHero-smallCard3.js-trackedPost, .extremeHero-smallCard.extremeHero-smallCard2.js-trackedPost, .extremeHero-mediumCard.js-trackedPost')
).forEach(el => {
let shouldHide = el.querySelectorAll('span.u-paddingLeft4').length;
if (shouldHide) {
el.style.background = "#FCBFB7";
}
});
Array.from(
document.querySelectorAll('section.m.n.o.ff.q.d')
).forEach(el => {
let shouldHide = el.querySelectorAll('svg.dl.dm').length;
if (shouldHide) {
el.style.background = "#FCBFB7";
}
});
setTimeout(clearMedium, 5000);
}

When I reload the webpage then below error occur:
I have to press ctrl+F5 each time to run the code. Why?
I got my solution. MY service-worker.js file was not correct. Now I paste below code in service-worker.js and it wored.
self.addEventListener('fetch', function(event) {});
I have a Javascript file that I'm calling in my Flutter Webview Plugin.
I am trying to return the callback in the console after the onReward method is called. This is the code of my js file:
<html>
<head>
<meta charset='utf-8'>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">
<meta http-equiv='X-UA-Compatible' content='IE=edge'>
<script type="text/javascript" src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
<script type="text/javascript" src="https://s3.amazonaws.com/cdn.theoremreach/v3/theorem_reach.min.js"></script>
</head>
<body>
<iframe src="https://theoremreach.com/respondent_entry/direct?api_key=845783b32b8bef12f1b55a36a8be&user_id=12345"></iframe>
<script type="text/javascript">
var theoremReachConfig = {
apiKey: "",
userId: "12345",
onRewardCenterOpened: onRewardCenterOpened,
onReward: onReward,
onRewardCenterClosed: onRewardCenterClosed
};
var TR = new TheoremReach(theoremReachConfig);
function onRewardCenterOpened(){
console.log("onRewardCenterOpened");
}
function onReward(data){
console.log("onReward: " + data.earnedThisSession);
}
function onRewardCenterClosed(){
console.log("onRewardCenterClosed");
}
if (TR.isSurveyAvailable()) {
TR.showRewardCenter();
}
</script>
</body>
</html>
And this is how I'm calling it in my Dart file:
...
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Reward earned"), actions: [
Text("$reward"),
]),
body: WebViewPlus(
javascriptMode: JavascriptMode.unrestricted,
onWebViewCreated: (controller) {
controller.loadAsset(
'assets/tr.html',
);
},
));
}
When I complete a survey I get the following message in my console:
I/chromium( 3560): [INFO:CONSOLE(28)] "onReward: 2", source: http://localhost:56537/assets/tr.html (28)
I want to scan this console message and just add the value of the reward, i.e. 2, in my existing page and display it in the appBar.
I would like to create an interactive image using goJs, however when i try and follow the tutorial to create a basic visual the output I get is just a blank box and not an interactive image with the words 'Alpha' and 'Beta' connected by a line.
This is my code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="https://unpkg.com/gojs/release/go-debug.js"></script>

<script>
function init() {
var $ = gp.GraphObject.make;
myDiagram = $(go.Diagram, "decisionTree");
var nodeDataArray = [
{ key: "Alpha" },
{ key: "Beta" }
];
var linkDataArray = [
{ to: "Beta", from: "Alpha" }
];
myDiagram.model = new go.GraphLinksModel(nodeDataArray, linkDataArray)
}
</script>

<body onload="init"()>

You are loading two different versions of the GoJS library. I suggest you remove the line:
<script src="go.js"></script>
EDIT: In addition, there are some typos that I missed before when just reading your code. This actually works:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="https://unpkg.com/gojs/release/go-debug.js"></script>
<script>
function init() {
var $ = go.GraphObject.make;
var myDiagram = $(go.Diagram, "decisionTree");
var nodeDataArray = [
{ key: "Alpha" },
{ key: "Beta" }
];
var linkDataArray = [
{ to: "Beta", from: "Alpha" }
];
myDiagram.model = new go.GraphLinksModel(nodeDataArray, linkDataArray)
}
</script>
</head>
<body onload="init()">
<div id="decisionTree" style="width:300px; height:300px; border:1px solid black;"></div>

new Vue({

],
origin:'http://s3.myimage.com/avatar.jpg'
},
mounted:function () {
console.log('ready');
alert('ok');
}
})
Also i want to set origin into an img after the page load.
Is it possible with vue??
Have you rendered it to your #app-7?
For your 2nd question, yes it's possible, you can set it up like
<img :src="origin" />
Then your img will take its source from your 'origin' string.-7
As a new developer on angularjs I have a specific question regarding provider. I'm trying to use the lazy load angular-lazy-load that has a specific functionality regarding the scrollable container. This scrollable container should be set in the config step.
Here is an example :
var myApp = angular.module('myApp', ['angularLazyImg']);
myApp.config(['lazyImgConfigProvider',
function(lazyImgConfigProvider) {
var scrollable = document.querySelector('.container');
lazyImgConfigProvider.setOptions({
offset: 1, // how early you want to load image (default = 100)
errorClass: 'error', // in case of loading image failure what class should be added (default = null)
successClass: null, // in case of loading image success what class should be added (default = null)
onError: function(image) {}, // function fired on loading error
onSuccess: function(image) {}, // function fired on loading success
container: angular.element(scrollable)
});
}
]);
myApp.controller('lazyCtrl', ['$scope',
function($scope) {
$scope.images = [{
url: "https://cdn.sstatic.net/stackoverflow/img/apple-touch-icon#2.png?v=73d79a89bded&a"
}, {
url: "http://www.skrenta.com/images/stackoverflow.jpg"

} ];
}
]);
.container {
overflow: scroll;
height: 200px;
position: absolute;

But my question is how can I do to add a container option if the container element is not yet created and will be by the controller ?
Thanks in advance, please let me know which informations are missing to answer.
Ok so the trick is to add an attribut lazyImgContainer to the container in the html file. Not yet documented in github so I have added a pull request to get it documented.
