This is really weird and my instructor is confused as well. I copied some code from my classmate — it worked fine on his computer. But it doesn’t work on mine.

The issue is with a search filter.

onChange={(e) => {
          if(!e.target.value) return setTransactions(allTrans)
          console.log(e.target.value)
          let search = transactions.filter((element) => {
            return element.description.includes(e.target.value)
          })
          if (search.length>0) setTransactions(search)
        }}

the stateful variable “transactions” is used here:

{transactions.map((transaction) => {
          return <Transaction key={transaction.id} transaction={transaction}/>
        })}

We figured out the issue is in the rerender. My instructor deleted this code and pasted it back in and that FIXED IT. But then it got messed up again when I edited something else (in a different file). And now I can’t fixed it.

What would be the reason identical React code works on my classmate’s computer but not mine?

I am looking for a way to simulate and animate waves, and other trigonometric math functions.

A great reference for this would be “The_Simulator” Tik Tok account.

Link to the account: https://www.tiktok.com/@the_simulator

he has a lot of simulations that I want to recreate, or create similar simulations for bussiness reasons.

any help would be much appreciated.

So I’ve created a button, along with a table that shows data from my database. However, I want that data to appear only when the button is clicked.

`<button id="breakfast2">Breakfast</button>
 <table id="mealTableContainer2">
            <thead>
                <tr>
                    <th id="mealname">Meal Name</th>
                    <th id="mealcalories">Calories</th>
                    <th id="mealtype">Type of Meal</th>
                    
                </tr>
            </thead>

            <tbody id="mealContainer2"></tbody>
  </table>`

The only Javascript I currently have is for getting my database into that table, but I really only want it to appear when I click the breakfast button. I just can’t figure out how; if someone could explain it to me very simply, I’d be appreciate it a ton!

we are using mocha + nodejs + axios

Below is the piece of code i have , they are all in different file.

File 1 : IT block

   it('Perform Post Payment Actions', function () {
    postPaymentController.triggerPostPaymentActions(params);
  });

File 2 : Controller

module.exports.triggerPostPaymentActions = function (params) {
  const actions = params.postAuthActionId.split('-');  // // 'PARTIALREFUND, 50, SUCCESS - PARTIALREFUND, 50, FAIL

  Object.entries(actions).forEach(([, action]) => {
    const actionAsArray = action.split(','); // 'PARTIALREFUND, 50, SUCCESS 

    switch (actionAsArray[0]) {. // PARTIALREFUND
      case 'PARTIALREFUND':
        paymentsPartialRefundApi.submitPaymentsPartialRefundApi(actionAsArray, params);
        break;
      default:
        break;
    }
  });
};

File 3: Acutal API Call using axios

module.exports.submitPaymentsPartialRefundApi = async function (actionDetails, params) {

  const postOptions = {
    url: partialRefundApiUri,
    method: 'POST',
    headers: restHeaders,
    data: params.partialRefundRequest,
  };

  try {
    const response = await axios(postOptions);
    params.partialRefundResponse = response.data;
    process.env.PARTIALREFUNDRESPONSE = JSON.stringify(params.partialRefundResponse);
  } catch (err) {
    process.env.ERRORCODE = err;
    process.env.SCRIPT_STATUS = 'failure';
    process.env.PARTIALREFUNDRESPONSE = 'Partial Refund request Failed';
    throw err;
  }



};

PROBLEM :

When the control is passed to submitPaymentsPartialRefundApi , then it builds the request for axios but rather than waiting for the axios call , it takes the control back to the switch case. my expectation was that since i am using async await it will execute and wait till the axios call is completed but rather than completing the call it returns the control back to the switch statement and from the switch it goes back to the IT block. so i have 2 problems.
1 Its not waiting for the axios call to end
2 Its not running switch twice in loop , its goes back to IT block and then comes back.

Solutions Tried :

I already tried using promises for this , with and without timeout but still it did not worked.
Any help on this is appreciated.

I’ve been trying to solve this for hours and I can’t.

The problem is when you try to erase the numbers entered.

You have to first select the two fields and enter the dollar amount in the third field. Then enter a value in the first field.

On the computer it works normally, but on some cell phones it is not working properly.

On some iphone using safary in the latest version it works. Already on some android devices with Google no. I didn’t check the browser version, but I tried it on newer and older phones. Some new ones give a problem and some don’t, as well as old ones.

This code was not developed by me, it is a little old and uses a template language called Freemarker. Don’t care too much about this language, it’s used to get data from the form and insert it into the html code.

There’s a link for you to access and test. This page contains two calculators, it is the first one that is giving problems. I’ll post a print of it.

I have a shopping cart component that I’ve passed a useState prop to update the number of items within the shopping cart / the amount of money that the cart is worth:

import { data } from "./data";

export default function StoreItems({ addToCart, Total, setTotal }) {
  const addToTotal = (data) => {
    addToCart();
    setTotal(Total + data.price);
  };
  return (
          <Grid container spacing={3}>
            {data.map((data) => (
              <Grid item key={data.id} xs={12} sm={6} md={3}>
                <Card>
                  <CardMedia
                    image={data.image}
                  />
                  <CardActions>
                    <div>
                      <Button>Buy</Button>
                      <Button
                        size="small"
                        sx={{ marginLeft: "5px" }}
                        onClick={addToTotal}
                      >
                        Add to Cart
                      </Button>
                    </div>
                  </CardActions>
                </Card>
              </Grid>
            ))}
          </Grid>
  );
}

The Data is a JavaScript object that looks like:

export const data = [
  {
    id: 1,
    title: "item 1",
    content: `Lorem ipsum dolor sit amet, consectetur adipiscing elit. Etiam ac aliquam nunc. 
    Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas.`,
    image: "https://source.unsplash.com/random/1",
    price: 5000,
  },
];

And the props are passed down from:

function Store() {
  const [cartCount, setCartCount] = useState(0);
  const [Total, setTotal] = useState(0);

  const addToCart = () => {
    setCartCount(cartCount + 1);
  };

  return (
    <>
      <div>
            <StoreItems
              Total={Total}
              setTotal={setTotal}
              addToCart={addToCart}
            />
      </div>
    </>
  );
}

export default Store;

Why is it that I am unable to add the price of data.price to the useState – Total object

How can we get a checkbox checked only if a dynamic value matches the checkbox value in one line without applying if condition. otherwise uncheck checkbox,.

I’m stucking a couple of days with ReactNavigation v6+, also there are several similar questions/answers about the invalid element type, but none of them is working with this simple example:

The issue was started after adding the material-top-tap navigation from @react-navigation module.

To avoid complexity, I use the minimal needed code lines to reproduce this error:

import React from 'react';
import {View, Text} from 'react-native';
import {NavigationContainer} from '@react-navigation/native';
import {createMaterialTopTabNavigator} from '@react-navigation/material-top-tabs';

const TopBarOne = () => (
  <View>
    <Text>TOP BAR ONE</Text>
  </View>
);
const TopBarTwo = () => (
  <View>
    <Text>TOP BAR TWO</Text>
  </View>
);

const TopTabBar = createMaterialTopTabNavigator();

const TopBarStack = () => {
  return (
    <TopTabBar.Navigator>
      <TopTabBar.Screen name={'one'} component={TopBarOne} />
      <TopTabBar.Screen name={'two'} component={TopBarTwo} />
    </TopTabBar.Navigator>
  );
};

const NavigationProvider = () => {
  return (
    <NavigationContainer>
      <TopBarStack />
    </NavigationContainer>
  );
};

export default NavigationProvider;

const Tweet = ({ tweet, checkedList, setCheckedList }) => {
  const [isChecked, setChecked] = useState(false);
  useEffect(() => {
    checkedList === [] && setChecked(false);
  }, [checkedList, isChecked]);
  return (
    <div className="tweet">
      <h3>Name : {tweet.name} </h3>
      <p>{tweet.tweet}</p>
      <input
        type="checkbox"
        checked={isChecked}
        onChange={() => {
          setChecked(!isChecked);
          checkedList.find((e) => e === tweet.id) === undefined
            ? setCheckedList([...checkedList, tweet.id])
            : setCheckedList(checkedList.filter((e) => e !== tweet.id));
        }}
      />
    </div>
  );
}; 

I have a tweet component that has its own state. There is an external checkedList with is basically an array of checked tweet ids.
But once I reset the checkedList = [] , I am trying to reset the checked tweets by useEffect. But can’t do it.
I want all tweets state to be unchecked. What am I doing wrong?

I need to disable checkboxes until the page load the data(products) and then enable them again,
this is my code for loading data:

function loadCounter(filterCounter) {
$.each(filterCounter.FilterCounter, function (key, value) {
    if (value.Count !== 0) {
        $("#filter .btn-groupl label :input[value='" + key + "']").parent("label").find("span.items-amount").text(value);
        $("filter .btn-group label :input[value='" + key + "']").parent("label").show();
    } else {
       ;
        $("filter .btn-group label :input[value='" + key + "']").parent("label").hide();
        
    }
});
