I am trying to create a web browser on Windows based on the Microsoft Edge Js Browser source code. Not only does my code turn into a listing directory when I run against localhost in Chrome, but I don’t know how to compile the code into an app, or just use Electron as possible. Please help.
Here is the link for the JsBrowser Source Code:
I’m trying to delete an item when being dropped in the dropzone that serves as bin. The tricky part here is that the dropzone must be in position:fixed and initially the draggable item is in position:relative. I think this causes the dropzone not to be able to detect when something is being dropped when the draggable is in a different position. I tried to fix this by changing position:absolute to draggable when item is being dragged but inevitably, the draggable overlaps the dropzone. How do I make this work?

This is my 1st attempt at a Chrome Extension. What I want to accomplish is to call a global javaScript function with arguments from my extension (content.js) which exists in the web app, in the tab. I would be making multiple calls to the function with different arguments based on the interaction with the extension. The extension is a form-based auditing tool.
When the submit button is clicked, a function getTestValues() is called in my content.js
SUBMIT_BUTTON.onclick = evt => getTestValues();
Within getTestValues() I want to call the global JS function with arguments, pixelAudit.staticPixels([arg1],[arg2])
pixelAudit.staticPixels(statusSelVal, outputModeVal);
I’m having issues finding much info on this? There is a ton for V2 but not much for V3. Is it even possible to do this? Any info, advice, or links are much appreciated.
Thank you!

I am learning how to incorporate JavaScript into HTML and am trying to build a very simple web game based off a class project. (This is a sidebar, I successfully completed the project itself.)
I need two specific images to randomly populate the entire table. My code successfully creates the array of appropriate length and translates that correctly to the HTML, but the image sources don’t seem to populate correctly. One image of each always shows up so I am confident my source paths are correct, and one of the images is always in the lower right hand corner, but the rest of the field is blank. When examining DevTools the array is there with appropriate img attributes but there is no source, except obviously on the img‘s that have a visible image.
class Field {
static generateField(h, w, pct = .2) {
let board = [];
let tempArray = [];
while (board.length < h) {
while (tempArray.length < w) {
const random = Math.random();
if (random < pct) {
tempArray.push(imageB);
} else {
tempArray.push(imageA);
}
}
board.push(tempArray);
}
for (let a = 0; a < h; a++) {
let row = document.createElement("tr");
for (let b = 0; b < w; b++) {
let cell = document.createElement("td");
let img = document.createElement("img");
img = board[a][b];
img.style.width = "100%";
img.style.height = "100%";
cell.appendChild(img);
row.appendChild(cell);
}
tblBody[0].appendChild(row);
}
}
}
The tblBody is defined outside the class. Originally my code was nested for loops and gave the exact same result.
Where am I going wrong?
I am building Pokemon filtered search app using Vue 3 with Composition API, based on the following tutorial: https://www.youtube.com/watch?v=QJhqr7jqxVo. The Home view in the app uses a fetch method to fetch Pokemon from the PokemonAPI:
fetch('https://pokeapi.co/api/v2/pokemon?offset=0')
.then((res)=> res.json())
.then((data)=> {
console.log(data)
state.pokemons = data.results;
state.urlIdLookup = data.results.reduce((acc, cur, idx)=>
acc = { ...acc, [cur.name]:idx+1 }
,{})
})
Each Pokemon in the JSON response includes an index number. The second promise uses a reduce method to handle urlIdLookup. urlIdLookup is then passed into the router-link path used to redirect to Pokemon about/details page:
<div class="ml-4 text-2x text-blue-400"
v-for="(pokemon, idx) in filteredPokemon" :key="idx">
<router-link :to="`/about/${urlIdLookup[pokemon.name]}`">
{{ pokemon.name }}
</router-link>
</div>
The tutorial, however, does not explain why it is necessary to create a new accumulator object (“acc”) inside the reduce method, and then deconstruct the accumulator (“…acc”). Could someone perhaps explain why it’s necessary to create that object, then deconstruct it? Also, is there perhaps a better method for retrieving the id and passing it into the router link?
Here is the full component:
<template>
<div class="w-full flex justify-center">
<input type="text" placeholder="Enter Pokemon here"
class="mt-10 p-2 border-blue-500 border-2" v-model="text"/>
</div>
<div class="mt-10 p-4 flex flex-wrap justify-center">
<div class="ml-4 text-2x text-blue-400"
v-for="(pokemon, idx) in filteredPokemon" :key="idx">
<router-link :to="`/about/${urlIdLookup[pokemon.name]}`">
{{ pokemon.name }}
</router-link>
</div>
</div>
</template>
<script>
import { reactive, toRefs, computed } from 'vue';
export default {
name: 'Home',
setup() {
const state = reactive({
pokemons: [],
urlIdLookup:{},
text: "",
filteredPokemon: computed(()=> updatePokemon())
})
const updatePokemon = () => {
if(!state.text) {
return []
}
return state.pokemons.filter((pokemon) =>
pokemon.name.includes(state.text)
)
}
fetch('https://pokeapi.co/api/v2/pokemon?offset=0')
.then((res)=> res.json())
.then((data)=> {
console.log(data)
state.pokemons = data.results;
state.urlIdLookup = data.results.reduce((acc, cur, idx)=>
acc = { ...acc, [cur.name]:idx+1 }
,{})
})
return { ...toRefs(state), updatePokemon }
}
}
</script>

I created a watcher collection where on create documents in the watcher, it will delete other documents and finally will delete the document itself inside watcher but it manage to delete like 450 out of 500 documents, the rest of the documents can’t be deleted. I have checked the documents, there are in the correct format. I was wondering if there is a issue with Firebase limitation
Essentially, I’m trying to recreate the “alert” and “prompt” functions, but in a single function that uses a modal window. I have it set up so that when one of the function’s parameters is set to 1, it adds a text field to the modal window and records that text field’s value when it closes. I’m having trouble making it so that when the window is opened, the program waits until the window is closed again. How can I do this?

I need to add button 01
title={
!editPasswordState ? "Edit Full Password" : "Cancel"

to Button 02 also, how can I do that? (Button one has a self-closing tag and button two has button start and button stop tags)
I wanted to try these out where the expandable row data came from the data itself where it will display these data inside the expandable row
"Personal Information1",
"Personal Information2",
"Personal Information 3"
All examples that I’ve seen is that the data of the expandable row is not from the variable data itself.
How do I access the data of the 3 different personal informations in which these will be displayed inside the expandable row?

I want to highlight column gaps somehow so it looks like separated.
So e.g. I want the gap be in red color between columns and no color between rows.
Setting borders to each element in grid makes the border lines intermittent.
So I thought there should be a way to style gap itself.
const Grid = styled.div`
display: grid;
grid-template-columns: 100px 50px 50px;
grid-template-rows: 50px 50px 50px;
grid-gap: 10px;

I am playing with jQuery and Javascript. Working on a TODOs app using li items and with this API: https://jsonplaceholder.typicode.com/todos. I receive 200 items from this API.
I am trying to post a new item created with a click from the button (btn-add) and everything works as expected, with the exception that the post request is leaving in blank one property which is “title”. Here is my HTML and JS code:

To reuse code I want to put my SVG into a function and call it as needed. Once I select the DIV what is the appropriate construct to render the SVG inside it?
...
if (intLocations.includes(comm.location)) {
const intActivities = d3.select('div#intActivities')
intActivities.append(Pill(comm))
} else {
const extActivities = d3.select('div#extActivities')
actActivities.append(Pill(comm))
}
...
function Pill(comm) {
const svgNode = d3.create('svg')
svgNode
.attr('width', 100)
.attr('height', 100)
.append('g')
// More code to draw the figure using comm data.
return svgNode;
}
