I am creating a p5js project and I want a code that prints the x and y of an ellipse. When I run the code it just shows up as the original x and y of the ellipse. How would I create a code that always changes the string printed on the screen.

I would like to add a marker to the map using the form. Can anyone help me? Installing the map works. I want to display markers after entering x and y, and read this data from the table. I have 2 inputs, one for X and the other for Y after clicking "add" I add this data to the table and I have 2 objects, etc ... but only one marker from state.items is displayed on the map, although I have more coordinates in the table.I know that the componentDidMount () method is only run once and here is the problem.Please Help
state={
items:[{
"X": 13.6155611,
"Y": 51.0331258
},
],
}
addItem = (e) => {
e.preventDefault();
const newItem = {
"Y": parseFloat(this.state.X),
"X": parseFloat(this.state.Y),
};
this.setState(prevState => ({
items: [...prevState.items, newItem]
}));
}
componentDidMount() {
const map = new mapboxgl.Map({
container: this.mapContainer,
center: [this.state.lng, this.state.lat],
zoom: this.state.zoom,
});
for (var i = 0; i < this.state.items.length; i++) {
var obj = this.state.items[i];
let myLatlng = new mapboxgl.LngLat(obj.X, obj.Y);
new mapboxgl.Marker()
.setLngLat(myLatlng)
.addTo(map);
}
}
render() {
return (
<div ref={el => this.mapContainer = el} />
<form onSubmit={this.addItem}>
<input
type="number"
value={this.state.X}
onChange={e => this.setState({
X: e.target.value
})}
/>
<input
value={this.state.Y}
onChange={e => this.setState({
Y: e.target.value
})}
/>
</Form>
)}

Try asking the people who wrote it.

Bootstrap is just css so yes, you can apply it.

Hi this works, but i would like to add other CountryCodes to include all french speaking countries.
<script language="JavaScript" src="http://www.geoplugin.net/javascript.gp" type="text/javascript"></script>
<script language="JavaScript">
if(geoplugin_countryCode() != 'US'){
if(geoplugin_countryCode() == 'FR'){
location.href = "indexfr.html";
}else{
location.href = "//index.html";
}
}
</script>
if (Type == 2 && (PageCount == 0 || PageCount == '')) {
as if commented out part worked....
the geoplugin generates the country code
Any help welcome
thanks

Hi Richard,
The commented part was to illustrate what I was trying to do, it wont work.
so it wont go to the indexfr.html page
Thanks

I think your syntax is not correct, try this:
var cc = geoplugin_countryCode();
if (cc == 'FR'|| cc =='CH' || cc =='LU' || cc =='BE' || cc =='LI'){
location.href = "indexfr.html";
}
|

Hi Richard,
Yes it was the syntax,
that was the neat and correct solution
Thanks

Yes, and I should have spotted it the first time. I will try harder in future.

It looks like all you need to do is debug it. I'm not sure what you were wanting us to do.

Basically, press F12 in your browser and your browser's developer tools will open. First, check the console to see if you have errors. Then you can click in the line of code you want to test and create a breakpoint.
Too much to go into here, but yes, you'll want to learn to debug.

I'm just getting started and learning through a book and this code won't run on google, was wondering why and what I needed to do to fix it. Thank you in advance.
<pre>
function zeroPad(number, width) {
let string = String(number);
while (string.length < width){
string = "0" + string;
}
return string;
}
function printFarmInventory(cows, chickens, pigs) {
console.log(`${zeroPad(cows, 3)} Cows`);
console.log(`${zeroPad(chickens, 3)} Chickens`);
console.log(`${zeroPad([pigs], 3)} Pigs`);
}
printFarmInventory(7, 16, 3);

Hi JaHowler,
Maybe you can try this.
function zeroPads(animal, width){
let strNumber = animal.toString(),
len = strNumber.length;
while(len < width){
strNumber += `0${strNumber}`;
len++;
}
return strNumber;
}
function printFarmInventory(cows, chickens, pigs){
console.log(`${zeroPads(cows,3)} Cows`);
console.log(`${zeroPads(chickens, 3)} Chickens`);
console.log(`${zeroPads(pigs, 3)} Pigs`);
}
printFarmInventory(7,16,3);
Output:
"7070707 Cows"
"16016 Chickens"
"3030303 Pigs"
Hope this helps. Thanks.
Cheers,
Jin

That code works fine for me in Firefox and Chrome. Which browser are you using, and what errors are you getting?

I have a Windows alert, after I click ok I want to chain the asychronous methods as synchronous. Not sure how?
alert('test')
.then(() => {
})
.then(() => {
})
.then(() => {
})
.then(() => {
});
I thought about using promise in JavaScript, but not clue so far.

alert pauses your code until the user clicks "OK", so there's no need for a promise.
NB: Since you've dropped support for Internet Explorer (which doesn't support arrow functions[^]) you might as well use an async function[^]. That will make your code easier to read.
