I have this array declared in my .ts file
opt_1=[];
opt_2=[];
opt_3=[];
opt_4=[];
and in .html component there is an outer loop
<span *ngFor="let list of current_lists[0]; let i = index">
<div *ngFor="let item of opt_{{i}}">{{ item }}</div>
<span>
this opt_{{i}} i want to make it dynamic so that i can access all the elements of array
<div *ngFor="let item of opt_{{i}}">{{ item }}</div>
but getting syntax related errors.
Any solution Thanks
I am creating a pop-up for my products when an icon is clicked. I want to make it so that the pop-up automatically disappears once the user clicks somewhere outside of the pop-up box. Currently, the only way for the pop-up to close and disappear is to click the same icon button that makes the pop-up appear to begin with. Id appreciate it if you could help me by using the code I provided as I am a beginner and will probably not be able to incorporate general suggestions but I will of course try my best! Thank you guys so much for the help and suggestions in advance.
HTML Pop up Code
<div class="box">
<div class="icons">
<a href="#contact" class="fas fa-shopping-cart"></a>

I am trying to create a graph using javascript where I will be able to show equations via y = mx + b. I have a few methods that would create the x and y axis and I have a method that draws the line, based on user input (on click of a draw line button). However, I am unable to figure out how to make the previous line disappear whenever I click the draw line button.
Graph.prototype.drawLine = function(slope, yintercept, color, thickness) {
console.log("Inside drawline");
console.log("this.maxX: " + this.maxX + " this.maxY: " + this.maxY);
var context = this.context;
// draw x and y axis
this.drawXAxis();
this.drawYAxis();
//context.clearRect(0, 0, this.canvas.width, this.canvas.height);
context.save();
context.save();
this.transformContext();
console.log("this.minX: " + this.minX);
console.log("this.iteration: " + this.iteration);
console.log("yintercept: " + yintercept);
console.log("slope:" + slope);
context.beginPath();
context.moveTo(this.minX, slope * this.minX + yintercept);
for(var x = this.minX + this.iteration; x <= this.maxX; x += this.iteration) {
if (this.iteration % 200 == 0){
console.log("x: " + x + " y: " + (slope * x + yintercept));
}
context.lineTo(x, slope * x + yintercept);
}
context.restore();
context.lineJoin = 'round';
context.lineWidth = thickness;
context.strokeStyle = color;
context.stroke();
context.restore();
};
This is my jQuery:
$(“#btnGraph”).click(function(){
//myGraph.clearCanvas()
var m1,b1,m2,b2 = 0;
m1 = parseFloat($("#m1").val());
b1 = parseFloat($("#b1").val());
var myGraph = new Graph({
canvasId: 'Graph',
minX: -10,
minY: -10,
maxX: 10,
maxY: 10,
unitsPerTick: 1
});
myGraph.drawLine(m1, b1, 'blue', 3);
//myGraph.drawEquation(function(x) {
//return 1 * x;
//}, 'red', 3);
});
Thank you!
I was fetching videos from an API and there were duplicates. So, I applied uuid to generate a key for each – key={uuid()} – until realizing that I was generating a new key for every render.
Below is my fix, but I am not quite sure if it’s really solving the issue.
export default function VideoList({ videos, observedElement }) {
const location = useLocation();
const videoList = videos.map((video, index) => {
video.uuid = uuid();
return (
<Link
to={`/videos/${video.id.videoId}`}
state={{ backgroundLocation: location }}
key={video.uuid}
>
<VideoListEntry info={video} ref={observedElement} />
</Link>
);
return <div>{videoList}</div>
}
Is it possible to hue shift the white space of a image on a HTML5 canvas. I’ve seen other methods of hue shifting a image but they all don’t hue shift white, they all shift the color black. If this is possible how would I go about doing it?
Thanks!
I have created a react application from which I am calling my server built upon php
Following is how I call my php file
const requestOptions = {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: JSON.stringify({ name, username, password }),
};
console.log(requestOptions);
fetch('http://localhost/crud/requests/signup.php', requestOptions)
.then(res => res.json())
.then(data => console.log(data));
Here is what I have in the PHP file
if (isset($_POST) && !empty($_POST)) {
// do something
}
however when I print the $_POST variable, I get an empty array. Event the $_RESPONSE is empty.
But when I tried to print the input stream like this
print_r(file_get_contents('php://input'));
Everything seems to be fine. Can anyone explain why does this happen.
I tried to read it in the documentation & looked up on some forums and blogs but wasn’t satisfied with the answers.
I would like to know how to find duplicates in fields in array object using
javascript.
from arrayobj, get same property model,then check
if typecode value is same but not SP, model same return that arrayobject
if typecode value has SP, model same return that arrayobject
else return []
for arrobj,
if model and typecode has same value, return those array object
if model same, any object typecode has value SP return those array
if above two conditions fails, return empty array
var arrobj1=[
{id:1, model: "interior", name: "lisa", typecode: "FL"},
{id:2, model: "interior", name: "peter", typecode: "FL"},
{id:3, model: "exterior", name: "john", typecode: "SP"}
]
var result1=isValid(arrobj1);
Expected Output
// result1
[
{id:1, model: "interior", name: "lisa", typecode: "FL"},
{id:2, model: "interior", name: "peter", typecode: "FL"}
]
var arrobj2=[
{id:1, model: "exterior", name: "lisa", typecode: "FL"},
{id:2, model: "interior", name: "peter", typecode: "FP"},
{id:3, model: "interior", name: "john", typecode: "SP"}
]
var result2=isValid(arrobj2);
Expected Output
// result2
[
{id:2, model: "interior", name: "peter", typecode: "FP"},
{id:3, model: "interior", name: "john", typecode: "SP"}
]
function isValid(list){
let result=[];
let duplicates = list.map((item, index) =>{
return list.find((x, ind)=> x.model === item.model && index !== ind );
})
duplicates.forEach(e=>{
if(e.typecode !== "SP"){
result.push(e);
}
})
return result;
}
I’ll make it quick. I researched a lot but I’m not sure why this is not working.
I have a textarea tag which I want to set to ‘data-something’ tag using setAttribute(“data-something”,””) command and it works just fine if I just list it out there. However what I’m doing is I”m creating a button that when clicked sets the attribute of the textarea to ‘data-something’, and no matter what it fails to operate when I nest setAttribute inside a myFunction and set button onclick=”myFunction()”. I’d appreciate if someone could explain a workaround that.
Thanks a ton for your patience.
This is what works:
<textarea></textarea>
<script>
textarea.setAttribute("data-something","")
</script>
This is what doesn’t work
<textarea></textarea>
<button onclick="myFunction()"></button>
<script>
function myFunction(){
textarea.setAttribute("data-something","")
}
</script>

According to the following two images, whenever I try to use this plugin in Table, it does not display Combobox values on the table.
What I want is for the values inside the Combobox to be displayed on the table.
Server part:
I have an ASR voice recognition AI model, it will generate data like below and use websocket to pass data to my server.
{ id: 1, segment: 1, data: "I am glad", final: false }
{ id: 2, segment: 1, data: "I am glad to": final: false }
{ id: 3, segment: 1, data: "I am glad to see you", final: true },
...
{ id: 50, segment: 3, data: "something other data...", }
On the other hand, my server has a bridge websocket to get and store ASR data then pass data to the clients.
Client Part:
When client get data from my websocket server, it would allow client to update the realtime data. So I use websocket to send back to the bridge websocket server. BTW, I can’t wait ASR segment to be final.
{ update: true, segment: 1, original: "I am glad", replaced: "I am v glad" }
{ update: true, segment: 1, original: "I am glad", replaced: "I am ve glad" }
{ update: true, segment: 1, original: "I am glad to", replaced: "I am ver glad to" }
My question is like how to design the bridge websocket server or there has a 3rd library I can use to handle this situation? Because when I use this pattern trying to update data, it doesn’t work correctly. The main reason is that I can’t handle ASR model generated time.
ex: I send update message to the server, but at the meantime ASR also send message to the client.
On my website, the sequence would be like
Below is my code:
let asrWS, timeout;
recordWS.on("connection", async (ws) => {
console.log("record socket connected");
ws.on("error", () => {});
ws.on("message", async (event) => {
const evt = JSON.parse(event);
if (evt.status) {
try {
if (evt.status === "start") {
sendStatus("pending");
const token = await login();
const { wsHost, ticket } = await getStreamInfo(token);
// connect to ASR websocket, store ASR data then broadcast to the clients
asrWS = await connectWS(wsHost, ticket, recordWS);
start(asrWS);
sendStatus("recording");
} else if (evt.status === "stop") {
stop();
if (asrWS) {
asrWS.close();
}
sendStatus("stop");
timeout = setTimeout(() => {
sendStatus("start");
}, 3000);
}
} catch (error) {
console.warn(error);
}
}
if (evt.update) {
// update ASR global data
setTranscripts(+evt.segment, evt.original, evt.replaced, "update");
console.log(getTranscripts());
}
});
ws.on("close", () => {
if (timeout) {
clearTimeout(timeout);
}
console.log("Disconnected record");
});
});
function connectWS(wsHost, ticket, recordWS) {
const webSocketUrl = `${wsHost}?ticket=${encodeURIComponent(
ticket
)}&modelName=${modelName}&rate=16000`;
const asrWS = new WebSocket(webSocketUrl, {
binaryType: "arraybuffer",
});
asrWS.onopen = () => {
console.log("open ASR server connection");
};
asrWS.onerror = (error) => {
console.error(`ASR server encountered error: ${error.message}`);
asrWS.close();
};
asrWS.onmessage = (event) => {
let d = JSON.parse(event.data);
// ...
const transcripts = getTranscripts();
const current = transcripts[+d.result.segment];
if (current) {
const re = new RegExp(current.original, "i");
d.t= d.t.replace(re, current.replaced);
}
d = JSON.stringify(d);

Ok so in my code I’m supposed to enter a number between 4 and 15. Then I click a button to add it, Once that happens the number will be added to the total number of ages and to one of the leagues I have created (it should be incremented by 1, for example, if I enter a 12 it will be 1 if I enter 12 again the total will say 2). When I try and run the code it does nothing.
<html>
<head>

<script>
function addAge()
{
// gets the input age
var age = Number(document.getElementById("age").value);
// clears the input field
document.getElementById("age").value = "";
// checks if age is between 4 and 15
if(age >= 4 && age <= 15){
// table cell to display total number of children
var total = document.getElementById("total");
// table cell to display total number of junior
var junior = document.getElementById("junior");
// table cell to display total number of intermediate
var intermediate = document.getElementById("intermediate");
// table cell to display total number of senior
var senior = document.getElementById("senior");
// increase total number of children by 1
total.innerHTML = Number(total.innerHTML) + 1;
