This code is trying to display a video function by embedding. I need to convert this to jsx to add it to my webpage or find another way to create a video call using react.
You can use https://magic.reactjs.net/htmltojsx.htm which is an online HTML to JSX compiler.
You can also use https://transform.tools/html-to-jsx beside https://magic.reactjs.net/htmltojsx.htm as mentioned above.
As described in the daily-js docs
Install the daily-co node package.
npm install #daily-co/daily-js
Then create a component that uses it.
// webpack/node-style require
//
const DailyIframe = require('#daily-co/daily-js');
let callFrame = DailyIframe.wrap(MY_IFRAME);
// or, cutting-edge, super-whizzy import
//
import DailyIframe from '#daily-co/daily-js';
let callFrame = DailyIframe.wrap(MY_IFRAME);
There is some tools online that convert Html to jsx and react components for exemple
https://helpfordev.com/html-to-jsx
When converting HTML to JSX there are five steps you need to apply:
All prop names follow camelCase
Number attributes use curly braces
Boolean 'true' can be written with just the property name. 'False' should be written with curly braces
The 'class' attribute is written as 'className'
In-line styles are provided as objects

I have a component1 selector that I called "app-component1".
#Component({
selector: 'app-component1',
templateUrl: './test-widget.component.html',
styleUrls: ['./test-widget.component.scss'] })
So to call the html of this component I usually use:
<app-component1></app-component1>
and it works perfectly fine.
Now from another component2 I have the following variable:
variableToBind = "<app-component1></app-component1>";
And In the html of component 2 I used the following:
<div [innerHtml]="varibableToBind"></div>
The html code binding isn't working. Is is possible to help me understand why and maybe help me find another alternative?
Thanks Everyone for the suggestions, I actually just find the answer to this:
This can't work because innerHtml is rendered AFTER Angular's compiled the templates. That means that it doesn't understand your selectors at this point of time.
If you guys want to load a component (or any content) dynamically, you should use *ngIf. It worked perfectly fine for me.
Angular sanitizes the HTML to prevent XSS attacks. You should find something like WARNING: sanitizing HTML stripped some content (see http://g.co/ng/security#xss). in your console output.
For further information, check out the documentation on property binding (esp. content security) and the security docs.
Depending on your use case, you need to choose another approach.
Your example code is not a valid approach as
1) html code cannot be bound to element property directly for security reason. ref: https://angular.io/guide/security#xss
2) There is no need to do property binding for HTML in your case. If you want to perform different logic inside AppComponent2, the best practice is to do property binding for the parameters that can customise component behaviours:
<div>
<app-component1 [prop1]="myVar1" [prop2]="myVar2"></app-component1>
</div>
and then you can customise it from the component properties instead of the component itself. This would make more sense.
If you really* need to pass HTML to component (for example if you have text with <br> tags or something like that), you can create custom Input like so:
export class YourComponent {
#Input() public htmlContent = '';
}
<div [innerHtml]="htmlDescription"></div>
And use it like so:
<your-component [htmlDescription]="textWithHtmlTags"></your-component>
* - for example if a string of text with basic HTML formatting tags (like <b>, <i> or even <br>) needs to be rendered.
In Angular, it is generally not recommended to bind a component selector using the [innerHTML] binding, because this can lead to security vulnerabilities. Instead, you should use Angular's template syntax and component structure to include components in your templates.
If you need to dynamically choose which component to include based on some condition, you can use the ngIf directive and the element to include a component only if a certain condition is met.
<ng-template [ngIf]="showMyComponent">
<my-component></my-component>
</ng-template>
Using NodeJS I would like to parse a variable defined in JSON, which is embeded in HTML of 3rd party website. What is the easiest way to get mentioned variable from HTML?
Chunk of HTML from which I would like to extract mentioned JS can be seen bellow:
...
<footer>
<div>
<script type="application/ld+json">
{"#context":"http:\/\/schema.org","#type":"BreadcrumbList","itemListElement":[{"#type":"ListItem","position":1,"item":{"#id":"https:\/\/www.domain.com\/","image":"https:\/\/assets.domain.com\/img\/facebook\/stuf.png","name":"Home"}}]}
</script>
<script>
var API_URL = ["https:\/\/api1.domain.com\/api","https:\/\/api2.domain.com\/api","https:\/\/api3.domain.com\/api"],
</script>
</div>
</footer>
...
The following HTML is parsed from XY website using NodeJS. I would like to avoid using eval().
I tried with JSDOM, but I didn't know how to select mentioned <script>. Is regex the only solution?
In case you provided, the selector will be: footer>div>script:nth-child(2).
Is this what you're asking for?
I was wondering if there's a way in javascript that allows me to process the html source code that allows me to take out specific tags that I want?
Sorry if it sounds easy or too simple. i am new to programming.
If you have the HTML in a string, then you can use:
var str = '<html></html>'; // your html text goes here
var div = document.createElement('div');
div.innerHTML = str;
var dom = div.firstChild; // dom is the object you want,
// you can manipulate it using standard dom methods
Alternately, use jQuery. jQuery is a library to help you manipulate and access HTML elements more easily. First, add this to the head of your document:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
This is a reference to the jQuery library. Then, do:
var foo = $("<html>Your html here</html>");
Or, if your html is in a variable (e.g. str), you can do:
var foo = $(str);
Then, you can manipulate and parse foo in a number of ways. For example, to remove all paragraph elements, you would use
foo.remove('p');
Or, to remove the paragraph element with id="bar", use:
foo.remove('p.bar');
Once you are done your modifications, you can get the new html text using:
foo.html();
Why is your html in a string? Is it not the html of the current page?
Use DOM it can pull data from webpages if you know the structure.
I have the following code in my view:
<apex:commandLink data-role="button" action="{!someAction}">
<apex:param name="someVar" value="someVarVal">
</apex:commandLink>
The code does not work because commandLink does not take the "data-role" attribute.
How can I pass a parameter like I am with the second line, but also have an attribute like "data-role" on the rendered link?
I've never found a way to put extra attributes into VF tags, your best bet IMO would be to add some javascript which runs on page load and then use JQuery's .attr() method to add the attribute to the component.
Something like the following (assuming you've included jquery through a static resource)
<apex:commandLink styleClass="myLink" action="{!someAction}">
<apex:param name="someVar" value="someVarVal"/>
</apex:commandLink>
<script type="text/javascript">
jQuery.noConflict();
jQuery(document).ready(function(){
jQuery(".myLink").attr("data-role", "button");
});
<script>
You'll notice I've used a class instead of ID here, this is simply because SFDC generated IDs include symbols which need to be escaped for use with jQuery, and I find this is just the easier and cleaner solution to use (albeit probably slightly slower).
you can just use html pass through syntax :
html-attribute=value
for example
html-class="toto" will output class="toto"
I have a requirement where I need to get the last HREF in the HTML code, means getting the HREF in the footer of the page.
Is there any direct regular expression for the same?
No regex, use the :last jQuery selector instead.
demo :
foo
bar
var link = $("a:last");
You could use plain JavaScript for this (if you don't need it to be a jQuery object):
var links = document.links;
var lastLink = links[links.length - 1];
var lastHref = lastLink.href;
alert(lastHref);
JS Fiddle demo.
Disclaimer: the above code only works using JavaScript; as HTML itself has no regex, or DOM manipulation, capacity. If you need to use a different technology please leave a comment or edit your question to include the relevant tags.
It's not a good idea to parse html with regular expressions. Have a look at HtmlParser
to parse html.
