I'm creating a FAQ, I have an array with the questions and answers, I managed to render this array on my page, but I want to edit different styles for the questions and answers, how can I do this? here is my code:
My FAQ list:
const FAQ = ({ props }) => {
const history = useHistory();
const classes = useStyles();
const dispatch = useDispatch();
const { user, userlist, isLoading } = useSelector((state) => state.Authentication);
const [expanded, setExpanded] = React.useState(false);
const handleChange = (panel) => (event, isExpanded) => {
setExpanded(isExpanded ? panel : false);
};
const WellbeingData = [
{
index: 1,
question: "Lorem ipsum dolor sit amet?",
answer:
"Tenetur ullam rerum ad iusto possimus sequi mollitia dolore sunt quam praesentium. Tenetur ullam rerum ad iusto possimus sequi mollitia dolore sunt quam praesentium.Tenetur ullam rerum ad iusto possimus sequi mollitia dolore sunt quam praesentium.",
},
{
index: 2,
question: "Dignissimos sequi architecto?",
answer:
"Aperiam ab atque incidunt dolores ullam est, earum ipsa recusandae velit cumque. Aperiam ab atque incidunt dolores ullam est, earum ipsa recusandae velit cumque.",
},
{
index: 3,
question: "Voluptas praesentium facere?",
answer:
"Blanditiis aliquid adipisci quisquam reiciendis voluptates itaque.",
},
];
and here is my last failed try to render it correctly
const questionList = WellbeingData.map((data) => <div style={{fontSize: 18, fontWeight: 'bold'}}><li key={data.index}>{data.question}</li></div>)
const answerList = WellbeingData.map((data) => <div style={{fontSize: 16}}><li key={data.index}>{data.answer}</li></div>)
{questionList}
<br/>
{answerList}
What could I do to solve this...
If the styles are limited, lets say "Answered", "New", "Deleted", you can have one css class for each style (e.g .deletedAnswer .deletedQuestion) and add a new element to your object like type: something, then dynamically choose a class based on the value of type. the easiest way is to set the value to the class name:
{
index: 3,
question: "Voluptas praesentium facere?",
answer:
"Blanditiis aliquid adipisci quisquam reiciendis voluptates itaque.",
class: "deletedAnswer"
}
And then just putting the value of array[index].class to your element's class.

I have a webpage with this section:
<section class="post__content">
At vero eos et accusamus et iusto odio dignissimos ducimus qui
blanditiis praesentium voluptatum deleniti atque corrupti quos
dolores et quas molestias excepturi sint occaecati cupiditate
non provident.
</section>
I need to get the text from that section.
I tried:
https://www.example.com/quote-of-the-day?d=01/09/2021/#post__content
IF the text is on the same PAGE as the script
console.log(document.querySelector("section.post__content").textContent
.replace(/(\r\n|\n|\r)/gm,"") // get rid of trailing newlines, remove if you need them
)
<section class="post__content">
At vero eos et accusamus et iusto odio dignissimos ducimus qui
blanditiis praesentium voluptatum deleniti atque corrupti quos
dolores et quas molestias excepturi sint occaecati cupiditate
non provident.
</section>
IF the text is on ANOTHER page which is on the same server as where you want to grab it, you can use jQuery or fetch. Here jQuery can parse the page and just grab the section
$.get("/quote-of-the-day?d=01/09/2021/ section.post__content",function(data) { console.log(data) })
Please note that class is .post__content and ID is #post__content
If NOT, then you need some server process
Try this:
const sectionText = document.querySelector("section.post__content").textContent
console.log(sectionText)
You can even create a function that gets an element's text:
const getElementText = selector => {
return document.querySelector(selector).textContent
}
const sectionText = getElementText("section.post__content")
console.log(sectionText)
NOTE: If you have more section tags with post__content class, then you should use document.querySelectorAll() which return an array of all nodes.
My axios response (or fetch, tried both) it's plain text (string). But I expect javaScript map. If I tried JSON.parse() (or from fetch .json()) I got error:
Uncaught (in promise) SyntaxError: Unexpected token in JSON at
position 0
at JSON.parse ()
at eval (List.vue?8915:66)
UTF-8 without BOM
I checked my json via few json validators online - json is valid
I tried create my json via some online json creator - the same error
so I have few questions:
I thought that json is a special format. If you got it via axios/fetch your response always will be js map? It's not true?
What is the best way to creating and validating json to be sure it's ok?
I use vue cli, there haven't json loader (i think so, not sure, it not use webpack, but I can't see some loaders). It could be problem? Or some environment settings? I tried to check it, but maybe can't find.
Or maybe ma header is still wrong, ad accept give me nothing?

Problem solved. I'm not sure why, but VSCode didn't want to save me file without BOM, so I still had UTF-8 with BOM
On August 20, 2020, Axios released v0.20.0 which addresses the issue of removing the byte order marker (UTF-8 BOM) when transforming the response.

I tried to extract the number of bathrooms by writing the code below, but I have received this error "AttributeError: 'HtmlElement' object has no attribute 'find_element_by_css_selector"
from lxml import html,etree
with open(r'listing.html', "r") as f:
page = f.read()
tree = html.fromstring(page)
Bathrooms = tree.find_element_by_css_selector('Bathrooms')
print('Bathrooms: {}'.format(tree.cssselect(Bathrooms)[0].text))
I am a beginner at HTML and CSS so I need your help.
import lxml.html
with open(r'listing.html', "r") as f:
page = f.read()
root=lxml.html.parse(page)
object_list = root.xpath(".//div[#class='bloco-dado']")
bathrooms = object_list[0]
text=bathrooms.text_content()
print(text)
Try this once, May this works
I'm trying to display a div with some example code for users. I want them to be able to select inside the div and use Ctrl + A to select all of the example code, but I don't want them to be able to edit the actual text (lest the remove a bit on accident and then it won't work).
I'm achieving this right now through contenteditable set on the div, but how do I get the same functionality of this attribute sans the actual text editing?
EDIT: Looking at the solution linked in #Mr. Llama's comment, I can use this method to achieve the primary functionality I'm looking for. However, if possible I would like to simply allow for the Ctrl + A command my users are familiar with, and still allow for the manual highlighting of snippets of the div's text. Again, all while disallowing the addition or removal of any text.
Seems to work for me when I prevent the onkeydown, oncut and onpaste events.
for (const elm of document.getElementsByClassName('editable-not-editable')) {
elm.setAttribute('contenteditable', true);
elm.spellcheck = false;
elm.oncut = () => false;
elm.onpaste = () => false;
elm.onkeydown = (event) => {
if (event.metaKey || event.ctrlKey) {
return;
}
event.preventDefault();
}
}
<div class="editable-not-editable">

Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it?

These cases are perfectly simple and easy to distinguish. In a free hour, when our power of choice is untrammelled and when nothing prevents our being able to do what we like best, every pleasure is to be welcomed and every pain avoided. But in certain circumstances and owing to the claims of duty or the obligations of business it will frequently occur that pleasures have to be repudiated and annoyances accepted. The wise man therefore always holds in these matters to this principle of selection: he rejects pleasures to secure other greater pleasures, or else he endures pains to avoid worse pains.'</p>";

You can`t control number of lines because of this:
tb1.TextWrapping = TextWrapping.Wrap;
Line count will depend on length of string. Long strings will be wrapped.
