Do you want to attach event handlers to all your buttons?

From the html you've shared, you need to do

$('button').on('click'....

Ehidin

@eabg

I orginally had button with no luck

so I tried that out and nothing

Sweet Coding :)

@SweetCodingInc

what do you want to happen when you click the button?

The event handler doesn't look right to me

Ehidin

@eabg

so im just trying to add some css changes to boxes..later do animate

Sweet Coding :)

@SweetCodingInc

With your code, let's say you click on the button 1. Then the clickButtonId will be btn1

and your selector will be#box1btn1

and there is no element with id="box1btn1"

Ehidin

@eabg

let me show you this. this was an earlier test and it was working before:

I wanted to start over cause an element got lost and i couldnt get it working again

Sweet Coding :)

@SweetCodingInc

@eabg you're better off using data attribute to target specific box

I'll show you an example

function diffArray(arr1, arr2) {
    var newArr = arr1.concat(arr2);
    newArr.filter(function(index) {
        if (!arr1.includes(index) || !arr2.includes(index)) {
            return newArr;
        }
    });
    console.log(newArr);
}

diffArray([1, 2, 3, 5], [1, 2, 3, 4, 5]);

can someone tell me whats wrong with this?

it always returns the concatenated array of the two

Aditya

@ezioda004

@lolativiwe_twitter .filter() returns a new array and doesnt mutate the original one so you're returning the concatenated array from the 2nd line

John Hawke

@lolativiwe_twitter

oh lol...

newArr = newArr.filter(....

this worked

thanks @ezioda004

@sjames1958gm

@lolativiwe_twitter Since the function should return the new array
return newArr.filter(... would probably be the "best" solution as it makes it clear that the filter is the function result.

I'm trying to solve dna-pairing but i don't know how it works... why is GCG dna-pairing GC, CG, GC again

Stephen James

@sjames1958gm

@raynor84 Each character in the string is paired with its designated value G with C, C with G and G with C again.

@raynor84 The pairing values are given in the instructions
