create canvas and msg.content in an outside function (discord.js/nodejs)
this has been bugging me for a while, I’ve created a pipboy like interface to display the condition of the character and built it into a solo functions but now i want to incorporate it into other display cards. The problem is every time i try to take the content out and put them in an external file the “canvas” or “msg” become undefined. This seems like a no brainer to off load to a function but I’m not sure how. i know i also have to pass “paperDollXoffset, paperDollXoffsetShort, paperDollYoffset, paperDollwidth, paperDollwidthShort”, and “paperDollheight” as their configured for the stand alone canvas and would need adjusting on merged canvases.
code follows
var CanvasW = 625;
var CanvasH = 500;
const paperDollXoffset = 0;
const paperDollXoffsetShort = 187.5;
const paperDollYoffset = 0;
const paperDollwidth = 625;
const paperDollwidthShort = 250;
const paperDollheight = 500;
canvas = Canvas.createCanvas(CanvasW, CanvasH);
context = canvas.getContext('2d');
background = await Canvas.loadImage('./images/photo-1538370965046-79c0d6907d47.jpg');
var useShortValuesArms = 0;
var useShortValuesLegs = 0;
var useShortValuesBody = 0;
var useShortValuesHead = 0;
context.drawImage(background, 0, 0, CanvasW, CanvasH);
context.strokeStyle = '#0099ff';
context.strokeRect(0, 0, CanvasW, CanvasH);

Regex: Anything that’s found with “700” should be found with “ddd” right?
I am experiencing an issue that I think is a regex bug. Before I submit to Google (chrome), can you just verify that if I do regex.test with:
/ddd/gim
it should be true in every case where
/700/gim
is true, correct?
(The source HTML file that I am running this on is too large to post)
var regex = /ddd/gim;
var obj = $();
var elems = $("Section P, section LI, section TD, section H1");
var num = 0;
elems.each(function() {
if (regex.test(this.innerText)) {
obj = obj.add(this);
num++;
}
});
console.log("num: " + num);
when I do this with /700/gim, it is matching text that /ddd/ isn’t
How to move a button from one div to another when clicked in reactjs?
I’ve placed the following buttons within a div
const [state, setstate] = useState([]);
const arr = [1,2,3,4,5];
return arr.map((num) => {
return (
<button
key={num}
className="buttons"
onClick={(e) => {
state.push(num);
}}
>
{num}
</button>
);
When those buttons are clicked, I want them to move to another div. And when the button is clicked on the other div, the button has to come back to the original div.I found a solution but it involves document.getElementById(). But I believe that it is not a good thing to do in reactjs. Any ideas?

Move next sibling element into previous sibling
I have a poorly formatted sidebar (aside) which I have no control over the structure.
But I want to make it the correct html structure by moving the elements which are supposed to be children into their parent elements.
I want to end up with something that is html valid:
<aside class="sidebar">
<div class="sidebar-nav">
<ul>
<li><a>Title 1</a>
<ul>
<li><a>Title 2</a>
<ul>
<li><a>Title 3</a>
...
...
</ul>
</div>
</aside>
At the moment this is the html structure I’m working with, and the javascript I’ve got to. I realise at this point the looping of the function is causing it to recursively append the next element into the previous.
However, this means that I end up with so many more iterations.
// -- get the sidebar list
const sidebarList = document.querySelector('div.sidebar-nav > ul');
const reorder = ((list) => {
const listItems = list.querySelectorAll(':scope li');
listItems.forEach((element) => {
// -- last h6 wont have a next sibling
if (element.nextElementSibling === null) return;
// -- if it is a second sub heading skip
if (element.nextElementSibling.tagName !== 'UL') return;
// -- add into the next element
element.innerHTML = element.innerHTML + element.nextElementSibling.innerHTML
});
})(sidebarList);<aside class="sidebar">
<div class="sidebar-nav">
<ul>
<li><a>Heading level 1</a></li>
<ul>
<li><a>Heading level 2</a></li>
<ul>
<li><a>Heading level 3</a></li>
<ul>
<li><a>Heading Level 4 - 1</a></li>
<li><a>Heading Level 4 - 2</a></li>
<ul>
<li><a>Heading Level 5</a></li>
<ul>
<li><a>Heading level 6</a></li>

</ul>
</ul>
</ul>

<li><a>Heading level 1</a></li>
<ul>
<li><a>Heading level 2</a></li>

<li><a>Heading Level 5</a></li>

trying to adjust a state object in redux but i can’t change the value of one property in the object
Ok so i have this very basic example of redux state
const initialState = {
good: 0,
ok: 0,
bad: 0,
};
const counterReducer = (state = initialState, action) => {
console.log(action);
console.log(state);
console.log(initialState);
console.log(state.good);
switch (action.type) {
case "GOOD":
return { ...state, good: good + 1 };
case "OK":
return { ...state, ok: ok + 1 };
case "BAD":
return { ...state, bad: bad + 1 };
case "ZERO":
return state;
default:
return state;
}
};
export default counterReducer;
i’m trying to change only one property of the state object on an onclick function named like this
const store = createStore(reducer);
const App = () => {
const addGood = () => {
store.dispatch({
type: "GOOD",
});
};
const addBad = () => {
store.dispatch({ type: "BAD" });
};
const addOk = () => {
store.dispatch({ type: "OK" });
};
return (
<div>
<button onClick={addGood}>good</button>
<button onClick={addOk}>ok</button>
<button onClick={addBad}>bad</button>
<button>reset stats</button>
<div>good {store.getState().good}</div>
<div>ok {store.getState().ok}</div>
<div>bad{store.getState().bad}</div>
</div>
);
};
const renderApp = () => {
ReactDOM.render(<App />, document.getElementById("root"));
};
renderApp();
store.subscribe(renderApp);
but when i try to change the value of any of the properties it doesn’t work , for example good , ok , bad but it crashes my app if i do so with good is not defined error
How to inject external javascript file to the page?
I need to inject some external js widget to the page. How to do that with the manifest 3? Seems like chrome.scripting doesn’t accept links.
How to link JavaScript and HTML5 pages without tag?
I am trying to make a button for my webpage that changes the ENTIRE colour palette of the page with Code.org AppLab. The only problem is, code.org doesn’t allow the use of the <script> tag for “security reasons”. As far as I know the only way I can turn on CSS settings with a button is with getElementById(). If anyone knows how to activate CSS settings when a button is clicked without JS, how to link external JS files to an html file, or use inline JS all WITHOUT the use of the <script> tag please show me how. Any help would be greatly appreciated.
I’m begging someone to help me PLEASE.
if statement with multiple or conditions returning wrong value
I am pretty sure I am missing something basic here but I am having trouble with using multiple or or || operators with my if statement.
For some reason the if statement is not catching the name variable:
testword = "billy"
if ((testword != "billy") ||
(testword != "tom") ||
(testword != "sara") ||
(testword != "michael")) {
console.log("none of the names match")
} else {
console.log("name found!")
}
When I try this I get none of the names match when I should get name found!
How to extract the data behind the interactive map/figure
There is an interactive map on website like this:
https://www.bostonglobe.com/2021/12/15/nation/these-are-all-massachusetts-towns-that-have-indoor-mask-mandates/#bgmp-comments
Where when the mouse hovers on it, it will highlight that area and show info for that certain area. How to get the data behind these and exact all the data to excel etc.? Is it written in Javascript?
Cannot read .length property of undefined (sometimes)
I’m trying to get checkbox values as an array, so later I can use them as part of a GET request.
Checkboxes are like this:
<input type="checkbox" name="diet" value="gluten"/>
<input type="checkbox" name="diet" value="vegetarian"/>
<input type="checkbox" name="diet" value="vegan"/>
I’ve (almost) catch them with this:
function getCheckboxValues(form){
var values= [];
var diet = form.diet;
for (let i = 0; i <diet.length; i++) {
if (diet[i].checked) {
values.push(diet[i].value);
}
}
return values;
}
Then I want to get them into:
var reqDiet = []; //global
So I can merge it into my get params
document.getElementById("submit-btn").addEventListener("click", function (){
reqParams = "&diet="+reqDiet+",
getRecipe(ASK_RECIPE, reqParams)
})
async function getRecipe(reqRecipe, reqParameters){
let response = await fetch(reqRecipe+API_KEY+reqParameters);
recipe = await response.json();
let recipeStored = JSON.stringify(recipe);
sessionStorage.setItem("recipe",recipeStored);
};
The problem is, if i run the getCheckboxValues("form_id") in console, it returns the correct array with items, but if i do something like
reqDiet = getCheckboxValues("form_id");
Console says :
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading ‘length’)
at getCheckboxValues
What I can understund from this is that my program is not recognizing “diet.length” as an array when I do the last one, but do recognize it when i run the function by itself.
I prefer to do this in vanilla JS since I’m new here and trying to do this small projects.
P.S. any feedback in the post is apreciated since is my first one and i think is pretty large :/ sorry about that
