I am using following code to create a html element in the page body with using YUI.
This code doesn't produce any error.
The issue is, the paragraph element is not created in the html page.
<html>
<head>
<title>YUI Test</title>
<meta charset="UTF-8">
<script src="http://yui.yahooapis.com/3.14.1/build/yui/yui-min.js"></script>
<script>
// Create a YUI sandbox on your page.
YUI().use('node', function(Y) {
// Create DOM nodes.
var contentNode = Y.Node.create('<p>');
contentNode.setHTML('This is a para created by YUI...');
});
</script>
</head>
<body>
<h1>Page body section...</h1>
</body>
</html>
The node is created, but it is also detached from the DOM. You have to attach it to the DOM by using either
Y.one('body').append(contentNode);
or
contentNode.appendTo(Y.one('body'));
or
Y.one('nav.main-navigation').insert(contentNode, 'before');
or any of the other methods for manipulating dom in YUI.

I am learning svg and would like to compare displaying svg items on different browsers. My code works fine on firefox, chrome, edge, safari etc, but cannot work on ie11. Unfortunately application I develop needs to support ie11 so I need to force my code to work correctly.
Here is fiddle: https://jsbin.com/hemawaboqa/1/edit?html,js,output
HTML
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/#svgdotjs/svg.js"></script>
</head>
<body>
<div style="position:absolute;left:0px;top:0px;right:0px;bottom:0px;overflow:hidden;" id="svg-main-container">
<div style="position:absolute;left:0px;top:0px;bottom:0px;right:300px;border:1px solid #dadada;overflow:auto;" id="svg-canvas"></div>
</div>
</body>
</html>
JS
var draw = SVG().addTo('#svg-canvas').size(400, 400)
var rect = draw.rect(100, 100)
Why that code is not working on ie11?
I have created a sample using the SVG.js 3.0 version with your code, it will show the "Object doesn't support property or method 'from'" in IE11 browser, perhaps the issue is related to the svg.js version, and it is a plugin issue, you could feedback this issue to SVG.js forum.
Besides, I suggest you could refer to the following code, to use the old version of SVG.js:
<!DOCTYPE html>
<html lang=en-us>
<head>
<meta charset=utf-8>
<title>TEST</title>
</head>
<body>
<div style="position:absolute;left:0px;top:0px;right:0px;bottom:0px;overflow:hidden;" id="svg-main-container">
<div style="position:absolute;left:0px;top:0px;bottom:0px;right:300px;border:1px solid #dadada;overflow:auto;" id="drawing">
</div>
</div>
<script src=https://cdnjs.cloudflare.com/ajax/libs/svg.js/2.6.6/svg.min.js></script>
<script>
(function () {
'use strict';
// Add title as first child of SVG element:
var createTitle = function (svgObject, text) {
var fragment = document.createDocumentFragment();
var titleElement = document.createElement('TITLE');
fragment.appendChild(titleElement);
titleElement.innerHTML = text;
svgObject.node.insertAdjacentElement('afterbegin', titleElement);
};
SVG.extend(SVG.Doc, {
namespace: function () {
return this
.attr({xmlns: 'http://www.w3.org/2000/svg', version: '1.1'})
.attr('xmlns:xlink', SVG.xlink, SVG.xmlns);
}
});
var draw = new SVG('drawing').size(300, 300);
var rect = draw.rect(100, 100).attr({fill: '#f06'});
// Add title to SVG element
createTitle(draw, 'Rectangle');
}());
</script>
</body>
</html>
The result as below:
The library you are using has ECMA 6 elements that are not understood in IE.
If you need your project to work in IE, you will have to use another library or find out how to change it so it allows for older browsers (as suggested here: https://svgjs.dev/docs/3.0/compatibility/)
I am following https://help.twitter.com/en/using-twitter/embed-twitter-feed for embedding timeline in the angular page. Only button renders but not the actual timeline.
The index.html looks like:
<body style="margin:0">
<script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>
<app-root></app-root>
</body>
app.component.html looks like below:
<a class="twitter-timeline"
href="https://twitter.com/TwitterDev/lists/national-parks?ref_src=twsrc%5Etfw">
A Twitter List by TwitterDev
</a>
Also tried things like app.component.ts:
ngOnInit(){
if ((<any>window).twttr.ready())
(<any>window).twttr.widgets.load();
}
But no luck
you need to load widgets.js script after twitter-timeline element is been render so if you place the script in index.html it is will load and the element hasn't render yet.
🌟 the best way around it is to create a script tag dynamically after the element is rendered.
twitter component
export class TwitterComponent {
#Input() user:string;
constructor(private renderer2: Renderer2,private el: ElementRef) {}
ngAfterViewInit() {
let scriptEl = document.createElement('script');
scriptEl.src = "https://platform.twitter.com/widgets.js"
this.renderer2.appendChild(this.el.nativeElement, scriptEl);
}
}
template
<a class="twitter-timeline" href="https://twitter.com/{{user}}">Tweets by {{user}}</a>
app componenet template
<app-twitter [user]="name"></app-twitter>
angular twitter widgets ⚡⚡
ngAfterViewInit() a lifecycle hook that is called after Angular has fully initialized a component's view.
Updated 🔥🔥
a simple soulution mention in this answer before by user named Bernardo Baumblatt
put the script link in the index.html
<script async src="https://platform.twitter.com/widgets.js" charset="utf-8">
</script>
load the twitter widgets when ngAfterViewInit method call
ngAfterViewInit() {
// #ts-ignore
twttr.widgets.load();
}
in any case the script has not loaded yet you will got an error like 🆘 twttr is not defined 👉 so download the widgets.js script and include it to your project by using import
main.ts
import './app/widgets.js'
demo 💥💥
I had a requirement of dynamically rendering timelines based on different twitter timelines.
I found a workaround by creating a variable in the constructor that stores the href based on the twitter username .
So for example if your link is "https://twitter.com/TwitterDev/lists/national-parks?ref_src=twsrc%5Etfw"
, you just put this in the constructor in a previously defined global variable , say "embedLink"
such as in your ts component:
#Component({
selector: 'app-tree-dashboard',
templateUrl: './tree-dashboard.component.html',
styleUrls: ['./tree-dashboard.component.css']
})
export class TreeDashboardComponent implements OnInit,AfterViewInit {
embedLink='';
constructor(private matIconRegistry: MatIconRegistry,
) {
this.embedLink= "https://twitter.com/TwitterDev/lists/national-parksref_src=twsrc%5Etfw"
}};
and then in your HTML :
<a class="twitter-timeline" href={{embedLink}}></a>
And lastly you only need to add the script in index.html which you have done already.
So you're good to go!
Below is my code. I'm creating blank website so I think it's should not be a problem. What I think is maybe the order of the script in index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Twitter</title>
<base href="/" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<link rel="icon" type="image/x-icon" href="favicon.ico" />
</head>
<body>
<app-root></app-root>
</body>
<script
async
src="https://platform.twitter.com/widgets.js"
charset="utf-8"
></script>
</html>
In my app.component.html
<a class="twitter-timeline"
href="https://twitter.com/TwitterDev/lists/national-parks?ref_src=twsrc%5Etfw">
A Twitter List by TwitterDev
</a>

How does one use NightwatchJs to automate clicking a specific part of an image? My naive approach is to select the coords attribute that matches the specific area of the image I'd like to trigger; but it doesn't work.
<img src="..." usemap="#example">
<map name="example" id="example">
<area shape="rect" coords="336,10,401,32" href="...">
<area shape="rect" coords="25,171,97,198" href="...">
...
</map>
Anyone encounter this issue or know of a work around? Thanks!
If I were you, I would play with the position of area elements inside the map element using CSS selectors like :first-child or :first-of-type. Here is a minimal working example:
PNG (map.png)
HTML/JS (index.html)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Nightwatch</title>
</head>
<body>
<img src="map.png" usemap="#map">
<map name="map">
<area shape="circle" coords="51,51,29">
</map>
<script>
// When the red area is clicked, we should display an alert.
var area = document.querySelector('area');
area.addEventListener('click', function () {
alert('OK');
}, false);
</script>
</body>
</html>
Nightwatch (script.js)
module.exports = {
'Clickable image map': function (browser) {
browser
.url('http://localhost:8000/index.html')
.waitForElementPresent('map', 1000)
.click('map > area:first-child');
// ...
},
};
Command
If your environment is properly set up, you can run the script with nightwatch -t tests/script.js. You will see the alert, meaning that the red area has been clicked by Nightwatch.
I am using the layout taglib to extend a page to its template but i don't know how to pass a variable to the main layout and apply a conditional class.
Considering this is my main-layout.marko
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body class="#### (TITLE === 'REGISTER')?'ACTIVE':'INACTIVE' ####">
<layout-placeholder name="title"/>
<layout-placeholder name="body"/>
</body>
</html>
this is my registration.marko
<layout-use template="./layout.marko">
<layout-put into="title">
$data.title
</layout-put>
<layout-put into="body">
some content
</layout-put>
</layout-use>
and finally this is the code I use to render the page and pass the title data
router.get('/register', function(req, res, next) {
registration.render({
title: 'register'
}, res);
});
How can I create a conditional class on the main-layout.marko file that switches between active or inactive depending on the page title?
Thanks
You can pass data to a layout by adding additional attributes to your <layout-use> tag. See: marko-layout » Layout Data
For your example, the following will work:
In main-layout.marko:
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body class="#### ${data.title === 'REGISTER' ? 'ACTIVE' : 'INACTIVE' } ####">
<layout-placeholder name="title">
${data.title}
</layout-placeholder>
<layout-placeholder name="body"/>
</body>
</html>
In registration.marko:
<layout-use template="./layout.marko" title="${data.title}">
<layout-put into="body">
some content
</layout-put>
</layout-use>
That should solve your problem, but let me know if you are still stuck.
there is another way of passing data t all of its template that is using $global in which you are passing your data .
and after using global you dont need to add attribute to any tag . you can access it by using like
out.global.username
I trying to create main page (part of node.js and mongoDB application) that includes login form.
To add view part I included js files with function that returns HTML, but as I can see much better is using template engine.
Everything is OK until I including one compiled swig part inside another one.
The output of main page is OK, but login part outputs like text on the page.
How is possible to output the login HTML as HTML instead of plain text?
Does more information needed to understand the issue?
Thank you in advance.
var swig = require('swig');
var mainPage_tpl = swig.compileFile(__dirname+'/../views/mainpage_tpl.html');
var formLogin_tpl = swig.compileFile(__dirname+'/../views/login_tpl.html');
var loginOutput = formLogin_tpl();
var mainPageOutput = mainPage_tpl({
title: 'Sometitle',
pagetitle: 'Somepagetitle',
content: loginOutput
});
exports.get = function(req, res){
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(mainPageOutput);
res.end();
}
mainpage_tpl.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>{{title}}</title>
<link rel="stylesheet" href="/assets/reset.css" />
<link rel="stylesheet" href="/assets/style.css" />
<script type="text/javascript" src="/assets/jquery-2.0.0.js"></script>
<script type="text/javascript" src="/assets/script.js"></script>
</head>
<body id="login_page">
<h1>{{pagetitle}}</h1>
<div id="content">{{content}}</div>
</body>
</html>
If you want to include literal HTML, you need to tell Swig to not escape it using the safe filter:
...
<div id="content">{{ content|safe }}</div>
...
