I am doing react native project.
There we are getting questions and answers as Json data. For Answers, We are getting HTML content in answers key.
So, I have to show number of answers in flatlist.
Is there anyway to render HTML content without using Webview?
Json is like following sample:
[ { question: 'How do I change or reset my password?',
answer: <p style="color:#B22222">Color text and <span style="color:limegreen;">another color</span>, and now back to the same. Oh, and here's a <span style="background-color:PaleGreen;">different background color</span> just in case you need it!</p>
},
{ question: 'How do I change my user name?',
answer: <p>Here's a blockquote:</p>
<blockquote>Contents should not be swallowed. This is due to the enormous amount of harmful chemicals that has gone into this burger.</blockquote>
<p>That was a blockquote.</p>
},
{ question: 'How do I change my email ID?',
answer:<p style="font-size:18pt">Text size using points.</p><p style="font-size:18px">Text size using pixels.</p><p style="font-size:larger">Text size using relative sizes.</p>
},
....
]
The data is dynamic and different answers & questions.
Any suggestions, Without using Webview, Can we render HTML content into flatlist for loop.
Try using react-native-render-html:
...
import HTML from 'react-native-render-html';
...
<HTML tagsStyles={{
p: styles.textAuthor}}
html={htmldata}
imagesMaxWidth={screen.screenWidth}
/>
With this library you can manipulate HTML nodes before rendering.

I'm setting HTML returned from the API in my Angular component:
<div [innerHTML]="content"></div>
content in this example is something like this:
<table>
<tr>
<td>[audioPlayer:file.mp3]</td>
</tr>
</table>
Now I would like to inject the actual component inside the table cell.
If I make a certain container, I can create the component with createComponent:
audioPlayerComponentRef: ComponentRef<AudioPlayerComponent>;
#ViewChild('placeholder', { read: ViewContainerRef }) container;
const factory: ComponentFactory<AudioPlayerComponent> =
this.componentFactoryResolver.resolveComponentFactory(AudioPlayerComponent);
this.audioPlayerComponentRef = this.container.createComponent(factory);
Then I can inject it into a container in the template:
<div #placeholder></div>
However, going back to my original goal, I can't use such a container, as the component needs to be injected into a specific position into an innerHtml block.
I've been brainstorming all day, but I can't see any way to achieve this.
Generally speaking, this is contrary to the way Angular works. [innerHTML] is not parsed for any Angular functionality. No component selectors or even a ViewContainerRef can be found there. Rather, even remotely suspicious HTML, CSS and JS is removed as a security measure as Angular only trusts its own templates.
So InnerHTML is a no-go. But I was in the same boat myself and have written a library to solve this exact problem. With it, you can freely load dynamic components into strings without compromising security. If you're still stuck on this, you might wanna have a look at it.
So I am working with an API, and found this in the documentation:
let message = {
"text" : "<i>or</i> HN: the Next Iteration<p>I get the impression that with Arc being released a lot of people who never had time for HN before are suddenly dropping in more often. (PG: what are the numbers on this? I'm envisioning a spike.)<p>Not to say that isn't great, but I'm wary of Diggification. Between links comparing programming to sex and a flurry of gratuitous, ostentatious adjectives in the headlines it's a bit concerning.<p>80% of the stuff that makes the front page is still pretty awesome, but what's in place to keep the signal/noise ratio high? Does the HN model still work as the community scales? What's in store for (++ HN)?",
"time" : 1203647620
}
So in react (using function component), what is the proper way of rendering message.text? I am asking because my rendering output still has the tag <i></i> and <p></p> in the text when I return {message.text}. So I guess there is something wrong.
If you want to render a string containing html you can use dangerouslySetInnerHTML
In your case will be:
<div dangerouslySetInnerHTML={{ __html: message.text }} />
Watch out using this attribute because it could expose your app to XSS attacks. (check https://reactjs.org/docs/dom-elements.html#dangerouslysetinnerhtml)
I am volunteering to write a quick AngularJS App for a non-profit. I have set up Angular successfully but the one problem I am coming across stems from the JSON.
I have a JSON object that contains multiple paragraphs. Therefore I need to separate the paragraphs onto two lines. I did some research and I found some answers to similar questions but because they were not put in context I did not understand them. I tried looking to see if JSON had something built in that forced a line break, because that would do, but I did not find that.
Help is greatly appreciated!
HTML w/ Angular JS
<div class="bio">
{{exhibits[whichItem].bio}}
</div>
JSON
[
{
"name":"Name goes here",
"bio":"First long block of text goes here then it needs a break <br /> and the second long block of text is here."
}
]
#user5854648 Your back-end sending the JSON response in this format .If you are using angular version greater than 1.2 to display the text content with html tags(People's calling this as unsafe html ) use angularjs inbuilt service called $sce .To make it as a reusable component created a custom filter.
var demoApp = angular.module('demoApp',[]);
demoApp.filter('trustAsHtml', [
'$sce',
function($sce) {
return function(value) {
return $sce.trustAsHtml('html', value);
}
}
]);
then make changes in html like
<div class="bio">
{{exhibits[whichItem].bio | trustAsHtml}}
</div>
or
<div class="bio">
<p ng-bind='exhibits[whichItem].bio | trustAsHtml'></p>
</div>
I am not an experienced coder so excuse me if my explanation isn't perfect.
I'm making an html page and I'd like there to be a section that shows some Osu! stats. There's this osu api that spits out all of the information I could possibly need but there's a litle bit too much of it.
https://osu.ppy.sh/api/get_user?k=ff96ad02d159e0acad3282ad33e43a710dac96d5&u=Sceleri
The above returns:
[{"user_id":"6962718","username":"Sceleri","count300":"93129","count100":"15744","count50":"3404","playcount":"776","ranked_score":"184300015","total_score":"258886799","pp_rank":"345687","level":"34.115","pp_raw":"314.239","accuracy":"94.54791259765625","count_rank_ss":"1","count_rank_s":"55","count_rank_a":"74","country":"FI","pp_country_rank":"4112","events":[]}]
I'd like to parse a few numbers from there. Example:
"pp_raw":"314.239" -> <p>;314.239</p>;
The <p> would be inside a div and so on, where I can specify some CSS to it and make it look good. The main problem is extracting the data to separate <p> elements.
I have executed this with regex in Rainmeter before (I had help) but I have no idea how to do it in html.
Use Jquery ajax calls. The url you posted basically gives you a json object.
HTML:
<div id="pp_raw">
</div>
Jquery
$.get( "https://osu.ppy.sh/api/get_user?k=ff96ad02d159e0acad3282ad33e43a710dac96d5&u=Sceleri", function( data ) {
//You can put whatever you want in the style attr to make things pretty
$( "#pp_raw" ).html("<p style='color:red'>"+data[0]['pp_raw']+"</p> ");
});

I want to store some additional data on an html page and on demand by the client use this data to show different things using JS. how should i store this data? in Invisible divs, or something else?
is there some standard way?
I'd argue that if you're using JS to display it, you should store it in some sort of JS data structure (depending on what you want to do). If you just want to swap one element for another though, invisible [insert type of element here] can work well too.
I don't think there is a standard way; I would store them in JavaScript source code.
One of:
Hidden input fields (if you want to submit it back to the server); or
Hidden elements on the page (hidden by CSS).
Each has applications.
If you use (1) to, say, identify something about the form submission you should never rely on it on the server (like anything that comes from the client). (2) is most useful for things like "rich" tool tips, dialog boxes and other content that isn't normally visible on the page. Usually the content is either made visible or cloned as appropriate, possibly being modified in the process.
If I need to put some information in the html that will be used by the javascript then I use
<input id="someuniqueid" type="hidden" value="..." />
Invisible divs is generally the way to go. If you know what needs to be shown first, you can improve user experience by only loading that initially, then using an AJAX call to load the remaining elements on the page.
You need to store any sort of data to be structured as HTML in an HTML structure. I would say to properly build out the data or content you intend to display as proper HTML showing on the page. Ensure that everything is complete, semantic, and accessible. Then ensure that the CSS presents the data properly. When you are finished add an inline style of "display:none;" to the top container you wish to have dynamically appear. That inline style can be read by text readers so they will not read it until the display style proper upon the element changes.
Then use JavaScript to change the style of the container when you are ready:
var blockit = function () {
var container = document.getElementById("containerid");
container.style.display = "block";
};
For small amounts of additional data you can use HTML5 "data-*" attribute
<div id="mydiv" data-rowindex="45">
then access theese fields with jQuery data methods
$("#mydiv").data("rowindex")
or select item by attribute value
$('div[data-rowindex="45"]')
attach additional data to element
$( "body" ).data( "bar", { myType: "test", count: 40 } );
