Questions similar to this were either irrelevant or complicated. I’ve referred to this SO thread but still not getting my desired output.
Desired output:
Hi there, Anna!
Hi there, Je!
Hi there, Ram!
I’ve tried playing around with .map() but only resulted in no output.
Here is the code I’ve written:
import React from 'react';
import ReactDOM from 'react-dom';
class Greeting extends React.Component {
render() {
return <h1>Hi there, {this.props.firstName}!</h1>;
}
}
const names = ["Anna", "Je", "Ram"];
const greet_em = names.map(name => (<Greeting firstName={name}/>));
ReactDOM.render(
{greet_em},
document.getElementById('app')
);
I’m using Vue and have an application that uses a template file. This file can be updated and I’d like to keep state in the user session store of if they have downloaded a new copy of the file.
I can easily call a backend api to toggle this on a button click.
How would I wire up the button to download the file (same behavior as an a href) but also call the back end api to toggle the hasSeen variable in session store.
How can I redirect the user from one page to another using jQuery or pure JavaScript?
im using emoji api and i get emoji unicode’s like this U+1F425 to be able to show emoji’s in jsx. i have to replace U+1F425 to u{1F425} . basically i just need to get 1F425 from the api.
Emoji.jsx
import React, { useEffect, useState } from "react";
import Sidebar from "../../Sidebar/Sidebar";
import "./Emoji.css";
const Emoji = ({ isAuth, setIsAuth }) => {
const [type, setType] = useState([]);
const getEmoji = () => {
fetch("https://emojihub.herokuapp.com/api/all/group_animal_bird")
.then((resp) => resp.json())
.then((dat) => (console.log(dat), setType(dat)));
};
useEffect(() => {
getEmoji();
console.log(type);
}, []);
return (
<>
{type.map((emo) => (
<>
<h6>{emo.name}</h6>
<span>{emo.unicode}</span> // This Not
<span>{"u{1F985}"}</span> //This works
</>
))}
</>
);
};
export default Emoji;
thanks for your help!

How can I convert a DynamoDB JSON object to a regular object in JavaScript?
Example DynamoDB object:
{
"key1": {
"S": "val1"
},
"key2": {
"S": "val2"
},
"key3": {
"M": {
"key4": {
"M": {
"key5": {
"S": "val5"
}
}
}
}
},
"key6": {
"S": "val6"
}
}
Expected output:
{
"key1": "val1",
"key2": "val2",
"key3": {
"key4": {
"key5": "val5"
}
},
"key6": "val6"
}
i have a string which contains array in it and bracket , i want to extract data from it .
let vr = "- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API."
how can i dynamically identify if an array is present in this string , like take [Next.js Documentation] since it is an array. Please help me on this issue
I am trying to find a document in Mongoose by using findOne ( not find ), and I want to get the most recent document even though they may have identical fields.
For example, these are the documents in Mongoose:
// Let's say this one was created a week ago in Mongoose
{
name: "John Smith",
age: 27,
industry: "finance"
}
// This one was created this morning
{
name: "John Smith",
age: 27,
industry: "healthcare"
}
So I need to do a query along the lines of this:
const client = Client.findOne({name: "John Smith"});
console.log(client) // expect the document created this morning
So when I Client.findOne by name, I’m expecting the most recent document. However Client.findOne seems to just return the old one.
Any advice?
Let’s say I have the following two-dimensional array:
const array = [[1, 1], [1, 2], [2, 1], [2, 2]];
What I want to do is to find all the values under first index which have common zero index value. So the result should be the following:
[[1, [1, 2]], [2, [1, 2]]]
Or maybe Map would look better:
[Map(1 => [1, 2]), Map(2 => [1, 2])]
How can I do that? With or without lodash. My solution looks a bit bloated and messy:
const array = [[1, 1], [1, 2], [2, 1], [2, 2]];
const grouppedCartItemsMap = new Map();
array.forEach((item) => {
const [locationId, contractId] = item;
if (!grouppedCartItemsMap.has(locationId)) {
grouppedCartItemsMap.set(locationId, [contractId]);
} else {
const existingItem = grouppedCartItemsMap.get(locationId);
if (!existingItem.includes(contractId)) {
grouppedCartItemsMap.set(locationId, [...existingItem, contractId]);
}
}
});
I have a textbox for inputting the “milled volume” of a given log(wooden log). However I want to have this field auto filled by the same logs “initial volume” which is already filled and submitted in from a separate form and stored in a separate table, how can I reference the corresponding “initial volume” when a user clicks on the text box to fill in this text box
<div class="row">
<div class="col-md-4">
<label>Volume (m<sup>3</sup>)</label>
</div>
<div class="col-md-8 form-group">
<input type="text" class="form-control" name="milled_volume" required>
</div>
</div>I am having some trouble with the lifecycle methods in web components.
We want to dynamically order child elements being passed in as slots.
To illustrate, this web component takes a prop, iconPos, and will determine whether the icon will be placed at the start or end of the slot.
<my-component iconPos="start">
<img src="/path/icon.svg" />
<div>{this.list}</div>
</my-component>
I haven’t had any luck getting it working with ref:
dc6b89e7.js:2926 TypeError: Cannot read properties of undefined (reading 'prepend')
Here’s what I have so far:
@State() slotElement!: HTMLDivElement;
@Prop() iconPos: 'start' | 'end';
...
private createSlots() {
switch (this.iconPos) {
case 'start':
this.slotElement.prepend(<img />);
break;
case 'end':
this.slotElement.append(<img />);
break;
default:
throw new Error(
`Invalid value `${this.iconPos}`, passed into `iconPos`. Expected valid values are `start`, `end``.
);
}
}
render() {
return (
// iconPos="start"
<parent-component>
<div ref={(el) => (this.slotElement= el as HTMLDivElement)}>
<slot></slot>
</div>
</parent-component>
)
}
I would prefer to not use a CSS solution if possible. Any help would be much appreciated!
This might be a weird question but I believe nothing is completely impossible.
I have a List of Users in MongoDB, each user has among other things, properties array which is currently empty.
In Excel sheet, I have a data that represents each user’s properties which I want to programmatically insert in each user’s properties array.
Importing excel sheet is fast and easy to populating each user’s properties is what gives me the problem.
I have added userId, and PropeId, from the users and the properties they bought, so Identify them as seen below
router.put(‘/importdata’, async (req, res)=>{
// upload queries
const imported = req.files.importdata;
const uploadpath = path.resolve(`public/excel_maneger/uploads/ ${imported.name}`);
if (imported.truncated) {
throw new Error("Uploaded File is too big, should not be morethan 20 MB");
}
await imported.mv(uploadpath);
const file = render.readFile(uploadpath);
const sheets = file.SheetNames;
const data = [];
for (let i = 0; i < sheets.length; i++) {
const sheetname = sheets[i];
const sheetData = render.utils.sheet_to_json(file.Sheets[sheetname]);
sheetData.forEach((item) => {
data.push(item);
});
}
try {
const users = await User.find({role: 'Customer'})
for(let i = 0; i < users.length; i++ ){
data.forEach((d) => {
if(users[i].id == d.id){
User.updateMany(
{},
{
$set: {
properties: {
propeId: d.propeId,
},
},
},
(err, d) => {
if (err) console.log(err);
}
);
}
});
}
} catch (err) {
console.log(err)
}
})
The Problem is that this code updates everyone on the Database (including non specified users) with the same information, Please I need help, I am trying to import 11 thousand users information from excel to database

I have a dynamic list of links in html select which can select and redirect to another page, but i want to change it and load from modal, for one viewing of different filing forms and no longer redirect to another page.
<div class="input-group input-group-sm">
<div class="input-group-prepend ">
<span class="input-group-text">Select transaction to file</span>

catch (Exception) { }
</select>
<div class="input-group-append">
<button class="btn btn-secondary" name="btnToFile" id="btnToFile" type="submit">Select</button>
</div>
</div>
I’m using location.href to redirect based on the selected link.
<script>
var vFile = $('#toFile').val();
$.dialog({
icon: 'fa fa-spinner fa-spin',
title: 'Redirecting',
content: 'Please Wait...',
showConfirmButton: false,

});
var linkTime = setTimeout(function () {
location.href = vFile;
clearTimeout(linkTime);
$(".jconfirm").fadeOut(100);
}, 1000)
</script>
Now, i want to display all filing forms in modal but i have no idea how to do it.
