Im building a react app. in the app, Im receiving a message through an API and if I receive a message, the message automatically display to the user.
But the problem is if the user is on another tab, they cannot see whether a message is received. I want to make the react app tab active immediately if the user is browsing on another tab after receiving a message. Is there a way in react to make the tab automatically active?
Infant coder here, used a template for my site where I wanted to showcase my work. The problem is the UX is really bad; in my portfolio section, I want the users to click on one of the images so it opens a new tab, instead of zoom in on a photo. I’ve tried to modify the JS and create a new function new tab but when I do that it stops all the other scrips on the page and no info shows up. Maybe someone on here can help? Here’s the link to the template I’ve used: https://templateflip.com/templates/super-folio/
here’s the part of the code that’s tripping me up:
/**
* Big Picture Popup for Photo Gallary
*/
document.querySelectorAll(".bp-gallery a").forEach((function(e) {
var caption = e.querySelector('figcaption')
var img = e.querySelector('img')
// set the link present on the item to the caption in full view
img.dataset.caption = '<a class="link-light" target="_blank" href="' + e.href + '">' + caption.innerHTML + '</a>';
window.console.log(caption, img)
e.addEventListener("click", (function(t){
t.preventDefault();
BigPicture({
el: t.target,
gallery: '.bp-gallery',
})
})
)
}))When I changed it, I did:
/**
* Big Picture Popup for Photo Gallary
*/
document.querySelectorAll(".bp-gallery a").forEach((function(e) {
var caption = e.querySelector('figcaption')
var img = e.querySelector('img')
function NewTab() {
window.open(
"a", "_blank");
)
}))
Which worked, but made all of the other text on the page disappear or unresponsive.
Any help you could provide would be great!

As far as I know, Datatables (or any other table), cannot have two horizontal scrolls. I have added Fixed Columns from Datatables and fixed up to 6 columns out of 20 or so. The first 6 columns have taken almost 70% of the table view, so on the remaining 30%, other data cannot be seen properly.
Is there any way I can add another Horizontal Scroll on the Fixed Columns (I know this beats the purpose of fixing the columns)??
Try to use a IonInput on a project.
const { register, handleSubmit, formState: { errors } } = useForm({
mode: "onTouched",
reValidateMode: "onChange"
});
const fields = [
{
label: "Firstname",
required: true,
requiredOptions: {
maxLength: 10
},
props: {
name: "firstname",
type: "text",
placeholder: "Enter a username"
}
},
{
label: "Age",
required: true,
requiredOptions: {
min: 18,
max: 99
},
props: {
name: "age",
type: "number",
inputmode: "numeric",
placeholder: "Enter your age"
}
}
];
console.log(errors);
const onSubmit = (data : any) => {
console.log(data);
}
return (
<IonPage>

I did some research through internet but didnt get a fix. May anyone help?
Moreover, are there any other forms framework are good for ionic project? Thanks!!
I have an array of objects. Each object is a profile of a dog including name, breed, etc. I want to be able to map through the array, get the breed of dog, and call out to an API for a random image of that breed. Below is a portion my React code that I tried (and failed). To my understanding, it’s not working because useEffect only will call out once even though I’m mapping through the array. It is possible to call out for each breed I map through?
const urlDogBase = "https://dog.ceo/api/breed/"
const urlEnding = "/images/random"
const [dogImage, setDogImage] = useState({})
let availableDogs = DogData.map((dog,index) => {
const dogUrl = dog.breed
const fullUrl = `${urlDogBase}${dogUrl}${urlEnding}`
useEffect(()=>{
fetch(fullUrl)
.then((response) => response.json())
.then((data) => setDogImage(data.message))
.catch(() => console.log("oops error"));
}, []);
return(
<img src={dogImage} />
)
})
I’m trying to add more nodes to the taskRefContainer. Currently there is only one node and I’m accessing it with children but when I add an extra <div> so I can add an <input type="range" /> to that div the children obviously change. I’ve commented out the part that breaks it in the code below.
import { useState, useEffect, useRef } from "react";
import "./App.css";
import { initialTracks } from "./initialTracks";
function App() {
const [tracks, setTracks] = useState(initialTracks);
const [isPlaying, setIsPlaying] = useState(true);
const tracksContainerRef = useRef();
useEffect(() => {
const audioContext = new (window.AudioContext ||
window.webkitAudioContext)();
for (const audio of tracksContainerRef.current.children) {
audioContext
.createMediaElementSource(audio)
.connect(audioContext.destination);
}
audioContext.resume();
}, []);
useEffect(() => {
for (const audio of tracksContainerRef.current.children) {
if (isPlaying) {
audio.pause();
} else {
audio.play();
}
}
}, [isPlaying]);
return (
<div>
<h1>Audio Mixer</h1>
<button onClick={() => setIsPlaying(!isPlaying)}>play</button>
<div ref={tracksContainerRef}>
{tracks.map(({ path }, i) => (
// <div key={i}>
<audio key={path} src={path} />
// <input type="range" />
// </div>
))}
</div>
</div>
);
}
export default App;
According to an answer in a previous question the Canvas API “allows use of any font that can otherwise be used by the user agent with a CSS stylesheet” yet while I can normally use Lucida Console in my browser it fails to load in Canvas.
Here is the font assignment that fails:
ctx.font = '15px Lucida Console, Comic Sans MS';
It has no trouble loading Comic Sans.
Or you can look at the whole example here: https://jsfiddle.net/zt6m1qeg/1/

Iām trying to make a very good website, however, I cannot seem to figure out how to make something like summ.ga/extensionpart
In the URL bar, it shows either summ.ga/index.html. How can summ.ga/home or something
From the image above, I am trying to make a “path”
the below code gives the list of attendance whose WorkStatus is “P”, it takes last $and value($and: {$eq: [“$$attendance.WorkStatus”, “P”],},) from $filter, but i want to get count of each WorkStatus separately(i.e. “MIS”,”A”,”P”).
{$facet: {totalCount: [{ $count: “sum” }],aggregatedData: [{$project: {date: “$date”,
attendance: { $filter: { input: “$attendance”,as: “attendance”,cond: {$and: { $eq [“$$attendance.WorkStatus”, “MIS”], }, $and: {$eq: [“$$attendance.WorkStatus”, “A”],},$and: { $eq: [“$$item.WorkStatus”, “P”]
Im using react and that the last thing I have to do is make the tab that I am on Bold. So if I am on the home page then it’ll be bold, but if I switch to Pricing tab, that one will instead turn bold.

I’m trying to find a solution online but it’s not been fruitful so far, I want to fetch the data in Columns 1,2,3,4,5,6,7 that is last edited in Sheet1 and then feed it into Sheet2.
Giving you an example, If the data is edited in Sheet1 C2 that data should be added into Sheet2 in A2 and B2
What I’m trying to achieve is, if anyone updated Sheet one, I want to know the last update in Sheet 2, is it possible to do this via scrip?
Sheet1 Screenshot
Sheet2 Screenshot
I tried a lot of script editing and tried to modify it… so far nothing worked for me. š
I am just curious to know apart from the difference that JavaScript run on browser and NodeJS uses JavaScript as scripting language for backend services it there any difference in execution of NODE JS and JavaScript..
Thanks in Advance
