When I open some web pages, they may jump to another web page automatically after a while. For example, if you open https://list.jd.com/list.html?cat=670,677,688 it will jump to cfe.m.jd.com/…, then further jump to passport.jd.com that asks you to login. I think on the page list.jd.com/…, there must be a statement like window.location.href=...that causes the jump. But where is the statement? How can I find the statement in a systematic way? I mean I can press F12 and set a breakpoint on that statement then refresh the page to stop at that statement.

I’m working on a forum using Express/React and I’m having trouble submitting the data from the form to the database. For now I’m just trying to add topic titles to its own MongoDB collection but in the future I plan on adding more message content. I have no idea why it’s not working. I have another similar form for registering account and it’s working just fine. When I console.log(title) it shows the title so I know I’m getting the data but I’m stuck with getting that data to save to the database after debugging for several days. Again, what I’m trying to do is make a form and enter the title of a topic and save that data to a database so that users can enter a topic and (in the future) make their own posts inside the topic.

This is the error code I’m getting when I hit submit.

POST http://localhost:3000/topic/create 404 (Not Found)

Here is my url that the form is located under.

http://localhost:3000/topic/create

Here is my server.js route code.

app.use("/topic", topicRoutes);

Here’s my forumApiSlice

const TOPIC_URL = "/topic";
export const forumApiSlice = apiSlice.injectEndpoints({
  endpoints: (builder) => ({
    create: builder.mutation({
      query: (data) => ({
        url: `${TOPIC_URL}/create`,
        method: "POST",
        body: data,
      }),
    }),
  }),
});

Here is my form code.

const CreateTopic = () => {
  const [title, setTitle] = useState("");
  const [author, setAuthor] = useState("");

  const navigate = useNavigate();
  const dispatch = useDispatch();

  const [create] = useCreateMutation(); // forumApiSlice

  const { userInfo } = useSelector((state) => state.auth); // to get the author of the topic

  const submitHandler = async (e) => {
    e.preventDefault();
    try {
      const res = await create({ title, author }).unwrap();
      dispatch({ ...res });
      navigate("/");
    } catch (err) {
      toast.error(err.error);
    }
  };

  return (
    <FormContainer>
      <h1>Create Topic</h1>
      <Form onSubmit={submitHandler}>
        <Form.Group className="my-2" controlId="title">
          <Form.Label>Title</Form.Label>
          <Form.Control
            type="text"
            placeholder="Enter Title"
            onChange={(e) => setTitle(e.target.value)}
          ></Form.Control>
        </Form.Group>

        <Form.Group className="my-2" controlId="author">
          <Form.Label></Form.Label>
          <Form.Control
            type="text"
            value={userInfo.name}
            onChange={(e) => setAuthor(e.target.value)}
          ></Form.Control>
        </Form.Group>

        <Button type="submit" variant="primary" className="mt-3">
          Create Topic
        </Button>
      </Form>
    </FormContainer>
  );
};

And here’s my backend code.

router.post("/create", createTopic);

const createTopic = asyncHandler(async (req, res) => {
  const { title, author } = req.body;

  const topicExists = await Topic.findOne({ title });

  if (topicExists) {
    res.status(400);
    throw new Error("Topic Already Exists!");
  }

  const topic = await Topic.create({
    title,
    author,
    postCount: 1,
  });

  if (topic) {
    res.status(201).json({
      _id: topic._id,
      title: topic.title,
      author: topic.author,
      postCount: topic.postCount,
    });
  } else {
    res.status(400);
    throw new Error("Invalid Topic Data");
  }
});

I want to embed the Microsoft team chat interface in the Microsoft team’s tab application. Can someone please help me with this

I tried using Fluent UI, but didn’t find it very useful. As it requires a lot of customization, and it seems not supporting Android and ios verions

We are working on a large social network site built with a micro frontend architecture in React and utilize some private libraries. Our goal is to enhance user engagement by allowing users to embed HTML content, similar to Twitter, and include specific widgets (e.g., comments with details like the number of likes).

I’m seeking guidance or examples on how to kickstart the implementation of this functionality. Any references or advice on how to approach this within our tech stack would be greatly appreciated.

Thank you!

I’m being struggling a couple of days with search bar in my app, the problem is that when I search with particular name of products the products with that name show up but when I clear the search bar the entire products disappear not showing up after clearing search bar?

Here is my Code:

 const Home =()=>{

  // State
  const [categories, setCategories] = useState(categoryData)
  const [selected, setSelected] = useState(null)
  const [productst, setProducts] = useState (ProductData)
   
 
  // seach function 
     function handleSearch(text){

        const filterData = productst.filter((item)=>{
        return item.name.toLowerCase().includes(text.toLowerCase())
       })

       setProducts(filterData)

     }

    function renederHeader(){

   return(
         
         //Search Input 
            <View style={{ marginTop:SIZES.margin,}} >
                <TouchableOpacity 
                     onPress={()=>{}} 
                     style={{
                          flexDirection:'row',
                          alignSelf:'center',
                      }}>
                    <TextInput 
                      placeholder=" Find Your Favourite..."
                      placeholderTextColor={COLORS.lightGrey20}
                     // value={}
                      onChangeText={text=>handleSearch(text)}

So, Please if anyone can help me how to search in bar and get the certain products and when I clear the search bar the all products should show up normally not disappear as it is now.

Given the following code:

type OpenFileDialogReturn<TMulti extends boolean> =
  TMulti extends true ? FileList | null | undefined :
  TMulti extends false ? File | null | undefined :
  never

type OpenFileDialog = {
  (options: { multiple?: false, acceptedFileTypes?: string }): Promise<OpenFileDialogReturn<false>>
  (options: { multiple: true, acceptedFileTypes?: string }): Promise<OpenFileDialogReturn<true>>
}

export const openFileDialog: OpenFileDialog = (options = { }) => {
  return new Promise(resolve => {
    const input = document.createElement('input')
    input.type = 'file'
    input.style.opacity = '0'

    if (options.acceptedFileTypes) input.accept = options.acceptedFileTypes
    if (options.multiple) input.multiple = true

    input.addEventListener('input', () => {
      if (options && options.multiple === true) resolve(input.files)

      const file = input.files?.[0]
      if (!file) resolve(null)

      resolve(file)
    })

    input.click()
  })
}

TypeScript is throwing an error on the last resolve(file)

Argument of type 'File | undefined' is not assignable to parameter of type 'FileList | PromiseLike<FileList | null | undefined> | null | undefined'.
  Type 'File' is not assignable to type 'FileList | PromiseLike<FileList | null | undefined> | null | undefined'.ts(2345)
const file: File | undefined

I’ve tried several approaches, even wrapping everything in strict if/else blocks to make sure that TS understands that options.multiple is strict false at this point but nothing seems to work. Any help is appreciated.

I am using Nextjs14 and Supabase.

I have this select where the user can choose from. I am also passing it on the formValue which will be received on the server actions as FormData. Now, on the component, I can see the data of the formValue and the barangay field is there. However, passing in on the server actions, the barangay field can no longer be seen on the server actions.

This is my reusable component named DropDownList.tsx:

import React, { Fragment, useState, useEffect } from 'react';

  selected: string;
  onSelect: (value: string) => void;
  required: boolean;
  placeholder: string;
  value: string;
  name: string;
};

function classNames(...classes: string[]) {
  return classes.filter(Boolean).join(' ');
}

const DropdownList: React.FC<Props> = ({ options, selected, onSelect, required, placeholder , value, name}) => {
  // Initialize the selected state with the default selected value from the parent
  const [currentSelected, setCurrentSelected] = useState<string | null>(selected);

  // Update the selected state when the selected prop changes
  useEffect(() => {
    setCurrentSelected(selected);
  }, [selected]);

My server action: On this part, the value barangay is not present anymore. Only the rest of the values shows.
Sample FormData value. The barangay is not on the name and no value:

I have integrated https://github.com/gabrieldoty/simplify-scorm to show the SCROM file content and it’s working fine.
The system displays SCORM courses effectively, but it doesn’t retain user progress and input data. Our progress data is stored externally, and we need to load this JSON data into the SCORM content during page loading. This project is based on SCORM 2004, aiming to synchronize and save user progress seamlessly within the course materials.

here is the code sample

function setupScormApi() { 
                    API_1484_11.Initialize = Initialize;
                    API_1484_11.Commit = Commit;
                    API_1484_11.Terminate = Terminate;
                    API_1484_11.GetValue = GetValue;
                    API_1484_11.SetValue = SetValue;
                    API_1484_11.GetErrorString = GetErrorString;
                    API_1484_11.GetDiagnostic = GetDiagnostic;
                    API_1484_11.GetLastError = GetLastError;
                    API_1484_11.loadFromJSON = loadFromJSON; 
                }

i want the use to scroll only the content inside the sticky section of the parent element and also want the user to scroll only one item of the loop per mouse scroll and highlight the active section with opacity 1 and non active with opacity 0.5

<div
     id="stickyParent"
     class="tw-hidden sticky-parent tw-pb-[4.5rem] lg:tw-block tw-relative tw-h-[300vh]"
   >
     <div
     id="sticky"
       class="tw-sticky tw-top-[6.5rem] tw-h-auto tw-container main tw-overflow-auto"

How can I use await inside array map. My code is as below

...gridSelectedContracts
    .map((gridSelectedContract) => {
     i++;
     const arr = [];

     arr.push(

Can somebody help me how can I use await inside map

I am working on a project in which I created a ChatBot using React Js. Now, I want to implement/deploy my ChatBot in an existing WordPress website. I use iframe tag to display my ChatBot but the problem is iframe didn’t display my ChatBot perfectly as it takes complete web page which causes problem. Can anyone tell me how to implement or deploy my ChatBot in WordPress webite? I wants only ChatBot in WordPress webiste (in every signle page) in a same size, same location. Please suggest me solutions.

• I have tried many solutions like I use 000Webhost to deploy build files of my ChatBot by running this command npm run build and, then I try to use 000Webhost url in iframe.
• I also explore its other solution. I found that using WP-API will be very helpful but I found only JWT Authentication for WP REST API and I don’t know how to properly use it in WordPress webiste to deploy my ChatBot.
  I am waiting for your kind responses.
  Thanks.

In my project development, account services need to distinguish between formal and testing environments, which have the same domain name and different IPs. In the development environment, I need to initiate authentication requests to the test environment of the account server in the middleware. Prior to this, I had completed this task by modifying the local host file. Now, I want to complete this task through code configuration or request proxies. In my other project, I used the Whistle proxy and Axios proxy function to forward 8899 to complete this task, but in the nextjs project’s middleware, Axios cannot be used, so I don’t know how to implement similar functions.

I have tried to retrieve the proxy function of fetch, but I have not found any valid information

I run a simple NodeJs app on my server and i’m can’t solve a problem i encountred today.

The server is running CPannel/WHM and use passenger to display multiple node application. In one of them i use the npm package require-from-url. In localhost with the exact same parameters (same code, same url), no problem, but when i send my app on server, i can’t retrieve the content of the url.

When i check further, i get an Error: spawnSync node EACCES. Here is the function that failed on server side:

var parse = require("url").parse;
var resolves = require("./resolves.js");
var spawnSync = require('child_process').spawnSync;
var options = {
    cwd  : __dirname,
    stdio: ['ignore','pipe','ignore']
};
var requireFromString = require("./requireFromString.js");

function sync(urlString) {
    var url = parse(urlString),
        href = url.href;
    if(!resolves[href]) {
        var returns = spawnSync('node', ['fetch.js', href], options); // the error occurs here
        var err_str_filename = JSON.parse(returns.stdout.toString());
        if(err_str_filename[0]) throw new Error(err_str_filename[0]);
        resolves[href] = requireFromString(err_str_filename[1], err_str_filename[2]);
    }
    return resolves[href];
}

Here is the content of my returns variable that failed:

    ]
 },
 status: null,

}

I guess is question of passenger or node configuration. I’ve tried many things, nothing works. Any help or idea will be really appreciated.

I have to make a simple react component which displays a translated string on two rows, second row must start always with the third word.

example:

<div className="parent">
  <span>{t('myText')}</span>
</div>

myText value from the translation file is = “Text that I want to display”

I tried using this “Text that n I want to display” but didn’t work.

which would be the best and the simplest way to solve this?
