<form action="https://httpbin.org/get" method="GET">

Every time I click a submit button it always redirects to a page saying

This site can’t be reached. Check if there is a typo in httpbin.org.

It works on the tutorials I watched on Youtube.

I’ve been working on a mobile app with Expo React-Native for a while. Everything worked fine with Expo 52.0.37 and React-Native 0.76.7. However, since updating to Expo 53.0.9 and React-Native 0.79.2, my app has been crashing with the following error when I call createSagaMiddleware():

TypeError: 0, _reduxSaga.default is not a function (it is undefined), JS engine: Hermes

The Redux-Saga version is 1.2.3. I encountered the same issue after updating it.

import AsyncStorage from '@react-native-async-storage/async-storage';
import {legacy_createStore as createStore, applyMiddleware} from 'redux';
import {persistStore, persistReducer} from 'redux-persist';
import createSagaMiddleware from 'redux-saga';
import logger from 'redux-logger';
import rootReducer from '@reducers';
import rootSagas from '@sagas';

/**
 * Redux Setting
 */
const persistConfig = {
  key: 'root',
  storage: AsyncStorage,
  blacklist: ['home', 'wishlist', 'list', 'messenger', 'notification'],
  timeout: 100000,
};
const sagaMiddleware = createSagaMiddleware();

let middleware = [sagaMiddleware];
if (process.env.NODE_ENV === `development`) {
  middleware.push(logger);
}

const persistedReducer = persistReducer(persistConfig, rootReducer);
const store = createStore(persistedReducer, applyMiddleware(...middleware));
sagaMiddleware.run(rootSagas);
const persistor = persistStore(store);

export {store, persistor};

I’m trying to add redux-saga middleware.

I have returned to Adobe Animate after a hiatus of man years thanks to Apple killing Flash off. Now swfs and AS2 are dead, I am using it to create projects using JavaScript and Canvas.

Is there a JavaScript reference library specific to HTML5 Canvas in Adobe Animate? Either online or a book.

There does not seem to be much reference out there other than the odd YouTube video. The videos needs to be watched, which takes time, and they may not necessarily have the answer I am looking for.

We include jQuery and document ready code at the bottom of the page here:

<script src="https://songer.datasn.com/themes/stage2/_public/js/jquery-2.1.3.min.js"></script>
<script src="https://songer.datasn.com/themes/stage2/_public/js/main.js"></script>
<script src="/outsource/main-site-js/main-2.js"></script>

Which loads jQuery first and then 2 separate .js files that use $(document).ready(function() { .... }) to do stuff.

We have this in main.js:

$( document ).ready(function() {
    console.log('Document ready function in main.js --- Run!');
});

And these in main-2.js:

console.log('Hello from main-2.js');

if (window.jQuery) {
    console.log('jQuery is loaded!');
} else {
    console.log('jQuery is not loaded.');
}

console.log($);
console.log(jQuery);
console.log($( document ));

$( document ).ready(function() {
    
    console.log('Document ready function in main-2.js --- But not run, why?');
    
});

console.log('End of js file');

The weird issue is that the closure function for ready() is run in main.js but NOT main-2.js. Why?

See console log screenshot:

Why doesn’t the ready() closure run in main-2.js? The jQuery is apparently loaded and there are no obvious errors.

How do you place dynamic values within a database on a vue template. I am trying to add an id number to my delete button.

I keep getting this error:

Unquoted attribute value cannot contain U+0022 ("), U+0027 (')

This works:

<button
 type="button"
 @click.prevent="heart"
 :data-id=1"
 >
Delete
</button>

However when I try adding a dynamic variable to the data-id, it crashes the page:

<button
type="button"
@click.prevent="heart"
 :data-id="{{member.member_id}}"
>
Delete
</button>

i tried json encoding the value:

:data-id={{json_encode(member.member_id)}}"

it gave this error: Unquoted attribute value cannot contain U+0022 (“), U+0027

I tried implementing the map tracking for the user; it works well, but the destination coordinate is inaccurate. The destination is random and not accurate. I want it to be responsive so that when the user inputs their location, the system will provide a direction and routing that will lead them to the user’s locationThis is my website

I am using upstash context.call method to call my langgraph server. My langgraph server has an agent that autocompletes the notetext. when I do console.log on my body of context.call i can see the responses but I only see the workflowrunId when i call the route through frontend. Pls help what’s the issue here?

import { serve } from '@upstash/workflow/nextjs';
//import { TextDecoder, TextEncoder } from 'util';

export const { POST } = serve<{ noteText: string }>(
  async (context) => {
    const { noteText } = context.requestPayload;

    const { status, headers, body } = await context.call<ReadableStream>('langgraph-request', {
      url: `${process.env.LANGGRAPH_RUN_URL}/runs/stream`,
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        Authorization: `Bearer ${process.env.LANGSMITH_API_KEY}`,
      },
      body: {
        assistant_id: 'autocomplete_agent',
        input: { note_text: noteText },
        stream_mode: ['updates'],
      },
    });
    console.log('body:', body);

    return body;
  },

        status: failStatus,
        response: failResponse,
        headers: failHeaders,
      });
    },
  }
);

My frontend code:

const getSuggestion = debounce(async (noteText: string, cb: (suggestion: string) => void) => {
      try {
        const response = await fetch('/api/workflow/autocomplete/', {
          method: 'POST',
          headers: { 'Content-Type': 'application/json' },
          body: JSON.stringify({ noteText }),
        });

        if (!response.ok || !response.body) {
          throw new Error(`HTTP error! status: ${response.status}`);
        }
        console.log('response body frontend:', response.body.readStreamableValue);

        const reader = response.body.getReader();
        const decoder = new TextDecoder();

        let suggestion = '';

        while (true) {
          const { done, value } = await reader.read();
          if (done) break;
          
          // Directly append the decoded text
          suggestion += decoder.decode(value);
          console.log('suggestion:', suggestion);
          cb(suggestion); // Update UI progressively
        }
        
        cb(suggestion); // Final update
      } catch (err) {
        console.error('Autocomplete failed:', err);
        cb('');
      }
    }, 300);

I’ve confirmed:

The component is exported with export default

The import path is correct (triple-checked)

I restarted the dev server

But the error persists.

Any ideas why this might be happening?

I’m building a daily reminiscence app for my grandfather on iPad using Scriptable. It:

1. Loads a simple JSON profile
2. Calls the OpenAI Chat API to generate a gentle question
3. Presents it via Alert + Speech
4. Uses Dictation.start() to capture his spoken answer
5. Writes both Q&A into a local JSON log

Most of the code is working, but I keep hitting two errors in my Console log:

---

Console log
2025-05-10 17:17:15: Reminiscence app starting: 5:17:15 PM
2025-05-10 17:17:15: Generating question…
2025-05-10 17:17:16: OpenAI API Error: Error: No question generated
2025-05-10 17:17:16: Presenting question: Margaret, do you remember any special songs you enjoyed when you were younger?

2025-05-10 17:17:25: Saved conversation entry
2025-05-10 17:17:25: Presenting thanks for response: [No response recorded]

---

What I’ve tried so far

• OpenAI “no question generated”
  • Verified OPENAI_API_KEY is set and valid
  • Logged out the raw response from https://api.openai.com/v1/chat/completions
  • Fallback to hard-coded questions works if I disable useOpenAI
• Dictation error
  • Confirmed Scriptable has microphone permission
  • Tried both FileManager.local() and FileManager.iCloud() (for writing)
  • Wrapped await Dictation.start() in try/catch

---

My two big questions are

1. OpenAI: Why does my call sometimes throw “No question generated”? Is my request payload malformed, or is Scriptable handling the JSON response incorrectly?
2. Dictation: What steps are required to get reliable speech-to-text in Scriptable? The prompt appears, but Dictation.start() always fails with “Recognizing the audio failed.”

Any pointers on how to debug these two errors (or better patterns for calling OpenAI + Dictation in Scriptable) would be hugely appreciated. Thank you!

I’m working on a new website right now and need to be able to get the word count from a large range of popular/classic titles to compare the users input.
I’ve tried google books, penguin publishing, and open library. I’ll even take page count at this point. Preferably a free library.

how on your Github page, say https://orange.github.io/example4/, make the cache storage of the Gilroy.woff2 font and the img.png image for 1 year, preferably for free. Thank you all in advance for your answer.

I’m having an issue where I am fetching from a website in my Vue project, and the memory usage grows every refresh – when I first run the project in development mode and check the memory usage in my browser, the page sits at around 40 MB ram usage. However after refreshing somewhat frequently it goes over 1 GB ram usage, after which it does tend to reset. I am not sure if this is intended garbage collection but I would like to prevent the memory usage from peaking so high if possible. Any help would be appreciated!

Here is my API code which fetches the information:

export async function api(subDirectory) {
  try {
    const res = await fetch(
      `https://wheelcollectors.com/collections/${subDirectory}/products.json?limit=1`
    )

    const data = await res.json()

    const availableProducts = data.products.filter(
      (product) => product.variants[0].available === true
    )

    return availableProducts
  } catch (error) {
    console.error("Error fetching data:", error)
    return [] // Important to avoid undefined returns
  }
}

And here is where that API function is called on my home page.

<script setup>
import { ref, onMounted, onUnmounted } from 'vue'
import { api } from '../api.js'

let products = ref([])

onMounted(async () => {
    let data = await api("hot-wheels-premium-collection")
    //console.log(data)

    products.value = data.map((item) => {
        let name = item.title.split("*")[0]
        let brand = item.title.split("*")[2]
        let link = `https://wheelcollectors.com/products/${item.handle}`
        
        return {
            brand: brand,
            name: name,
            price: parseFloat(item.variants[0].price),
            link: link
        }
    })
})
</script>
