E mesmo assim o require não funciona

This is a field where either I have to access the file explorer in Windows and then select the file to upload or, I have to drag and drop the file to upload the file. I am using the following code in WebdriverIO, but the file upload in not happening.

 const fileUpload = $("//div[@id='customer_information']//div[@aria-hidden='true']");
 const path = require('path');
 const filePath = path.join(__dirname, '../../Test Data/Captute0.png');
 //const filePath = path.join(__dirname, 'F:\WebDriverIO\Capture.png');
 fileUpload.setValue(filePath);

I downloaded a template and put all the CSS in a folder and imported it into the App.js file, and now I want to import the JavaScript files, but it gives an error, I even used / * global jQuery * / and put it in the index.js file. I also imported js, but it still gives an error

Is it possible to import JS file at all? If so, thank you for your reply

I’m trying to write a function which will act on an array of data passed into it using AJAX. It’s not doing anything, and the last thing left that I can find that I might be doing wrong is the first parameter of my .apply() call (i.e. the owner of my underlyingFunction() method).

Here’s my code:

function XMLfunction(targetElement,param1,param2) {
    var workingArray = new Array(targetElement);
    var request;
    if (window.XMLHttpRequest) {
        request = new XMLHttpRequest();
    } else {
        request = new ActiveXObject("Microsoft.XMLHTTP");
    }
    request.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            var parser = new DOMParser();
            var xml = parser.parseFromString(this.responseText,"text/xml");
            for (var i = 0; i < xml.childNodes[0].childNodes.length; i++) {
                workingArray.push(xml.childNodes[0].childNodes[i].innerHTML);
            }
            alert (workingArray); // workingArray looks exactly like it's supposed to
            underlyingFunction().apply(this,workingArray);  // underlyingFunction() works perfectly when called directly in a script
            alert ("applied"); // XMLfunction() stops before it gets to this line
        }
    }
    request.open("GET","myURL.php?param1="+param1+"&param2="+param2,true);
    request.send();
}

The first parameter of .apply() here is this, but I have tried using document and, out of desperation, window as well. What should it be? Or what else am I doing wrong?

This is a follow-up question from a question that I asked and answered before:

https://stackoverflow.com/a/69762698/16136444

In summary, if I pick a choice on the 1st v-select, it will only display limited choices on the 2nd v-select, which are related to the first choice that I made on the 1st v-select. Then, after choices are made on the 2nd v-select, it will auto-generate and display the code assigned to that 2nd choice on the 3rd v-select.

Before it was successfully done on my testing firebase project and it works and it still is. But after I created a new firebase project and do the same thing, it did not work out.

1. Old firestore collection on my testing project

• Scope of Works > All docs contain scope value > Specialization > docs containing specialization & code

2. New firestore collection created for production project
   
   

So, the only thing that is changed is I removed spacing & use PascalCase for the name of the collection and documents. Other than it is all just the same. So now I used .collection("ScopeOfWork") (new) instead of .collection("Scope of Works")(old) to read from firestore

What could possibly be wrong with it? Any advice?

Thank you :))

Some Chrome URLs are just text files that are rendered as monospaced text files.
As an example, this is the Public Suffix List (https://publicsuffix.org/list/public_suffix_list.dat), and looks like this:

You can also get to this type of page by going to any raw GitHub user content, like https://raw.githubusercontent.com/github/docs/main/README.md.

I am building a Chrome extension and want to check what type of document the page has in the content script. My current code is this, and describes the HTML wrapper that I see around text:

const documentIsText = document.head.innerHTML.length === 0
        && document.body.children.length === 1
        && document.body.children[0].nodeName.toLowerCase() === 'pre'

This is the HTML wrapper I see:

<html data-lt-installed="true">
  <head></head>
  <body>
    <pre style="word-wrap: break-word; white-space: pre-wrap;">
    "Lots of text!"
    </pre>
  </body>
</html>

It seems like there should be some property of document that should answer this question.

It’s possible to check the document’s response header for content-type: text/plain with a background script, but I want to check for this information in a content script.

Question

What is the fastest way to definitively check that the page you are looking at is just text with client-side JavaScript after page load?

I have code like this.

const { data } = useSWR('/api/data', fetcher);
const [contents, setcontents] = useState<Array<string>>([]);

json is like this

console.log(data) 

Text: Array(5)
0: {id: 1, title: '123', content: 'hi'}
1: {id: 2, title: '1234', content: 'qq'}
2: {id: 3, title: '12323', content: 'ww'}
3: {id: 4, title: '123124', content: 'ee.'}
4: {id: 5, title: '24124', content: 'rr.'}

I want to output content in json as map and put it in setContents.

I think you can create a function and output it as a map, then call setContents and put a value in the return value, but it doesn’t seem to work..

How can I put json array contents in setContents??

I have a string like this:

This is a sentence.n This is sentence 2.nnnnnn This is sentence 3.nn And here is the final sentence.

What I want to is:

This is a sentence.n This is sentence 2.n This is sentence 3.n And here is the final sentence.

I want to remove all duplicated n characters from a string but keep only one left, is it possible to do like that in javascript ?

I have the following code that I run in the console:

// cache the starting array - 50 elements
let asTheyWere = selDocument.fields.field;
// create the new object
let nf = {};
$j.each(selDocument.fields.field[selDocument.fields.field.length - 1], function(a, b){
    nf[a] = b;
});
// make a change and add the object to the array
for(i = 0; i < 5; i++) {
    nf.name = `test me ${i}`;
    selDocument.fields.field.push(nf);
}
// assign the array to a new variable - now at 55 elements
let asTheyAre = selDocument.fields.field;
// check the values
console.log(asTheyWere);
console.log(asTheyAre);

I know that the console doesn’t update until the code is finished, so all variables are logged with their final value. I had thought that using different variables would avoid that, but asTheyWere and asTheyAre are the same, showing 55 elements (the first should have 50), AND the values appended to the end of the array are all the same as well: they should be ‘test me 0’, ‘test me 1’, ‘test me 2’ and so on, but they’re all ‘test me 4’.

What’s going on? How can I watch the progress and see accurate values?

I got an error while creating react app. How do I fix it?

I need to navigate back to the original requested URL after login.

For example, user enters www.example.com/settings as user is not authenticated, it will navigate to login page www.example.com/login.

Once authenticated, it should navigate back to www.example.com/settings automatically.

My original approach with react-router-dom v5 is quite simple:

const PrivateRoute = ({ isLoggedIn, component: Component, ...rest }) => {
  return (
    <Route
      {...rest}
      render={(props) =>
        isLoggedIn? (
          <Component {...props} />
        ) : (
          <Redirect
            to={{ pathname: `/login/${props.location.search}`, state: { from: props.location } }}
          />
        )
      }
    />
  );
};


<PrivateRoute exact isLoggedIn={isLoggedIn} path="/settings" component={Settings} />

Can some one tell me how to do that in v6? Thanks in advance

Instead of retyping repeated codes for a side bar in Javascript, I made a sidebar function which is used to populate similar codes for every pages. it looks like this:

function addSidebarTemplate(){
      const template = document.createElement('template');
      template.innerHTML = `<aside class="aside-container">
                            <header>
                <a href="."> link here</a>
                <a class="mr-1" href="#">
                    <i class="fab fa-linkedin"></i>
                </a>
                <a class="mr-1" href="#">
                    <i class="fab fa-facebook"></i>
                </a>
                <a class="mr-1" href="#">
                    <i class="fab fa-github"></i>
                </a>
                 </header>`
       document.querySelector('#sidebar').appendChild(sidebar.content);

There are other elements below this code. But none of them requires user’s input. I just wonder is this safe to use innerHTML in this case? If not, is there better way to insert the side bar like this?

Thanks

I have a function for Project Euler #7. Towards the end, I changed the code from primeArray.push(i); to primeArray.unshift(i) and return primeArray[primeArray.length - 1]; to return primeArray[0];. This altered the return. In the former. It returned the correct answer, 104021, while the latter returned 20001, which is not even prime. I do not understand why that is.

function primeFinder(primeTarget) {
  //since 2 is the only even prime, putting it here saves us some effort in checking primality by just iterating over the odd numbers
  //it also helps the for loop since we are only interested in checking for divisors among previous primes.
  let primeArray = [2];
  let i = 3;

  while (primeArray.length < primeTarget) {
    let primeLogger = false;
    //We don't need to check for divisibility by 2, so j can equal 1
    for (j = 1; j < primeArray.length && primeArray[j] < Math.sqrt(i); j++) {
      if (i % primeArray[j] === 0) {
        primeLogger = true;
        //Since we have found a divisor and changed primeLogger, we can exit the loop
        break;
      }
    }
    //Where the break goes to, and also where the for loop goes to once finishes
    if (primeLogger === false) {
      primeArray.push(i);
    }
    i += 2;
  }
  return primeArray[primeArray.length - 1];
}
console.log(primeFinder(10001));
