如何从当前索引中获取其他索引

Question

i'm a newbie on JavaScript, help me to fix the problem i got. I have an array, i want to remove class list for other div which are not same with the current index. Please help

i tried to find the answer from other discussion, but i still don't get what i want.

Here's the code:

window.addEventListener("load", ()=> {
const sounds = document.querySelectorAll(".sound");
const pads = document.querySelectorAll(".pads div");
const visual = document.querySelector(".visual");

pads.forEach((pad, index) => {
    pad.addEventListener("click", function() {
        sounds[index].currentTime = 0;
        sounds[index].play();
        popUpNote();

        const ind = index + 1;
        //I Need to got the other index from the current index,
        //like if current index is 2, then i want to get 0,1,3,4,5
        //since i have 6 index inside
        pad.classList.add("active-pad"+ind);

        sounds[index].addEventListener("ended", function() {
            const noteChild = document.querySelector(".visual div");
            noteChild.remove();
            pad.classList.remove("active-pad"+ind);
        });
    });
});

const popUpNote = () => {
    const note = document.createElement("div");
    visual.appendChild(note);
    note.style.animation = 'beatOn 1.5s ease-in-out infinite both';
};

});

I want to got the other index from the current index, like if the current index is 2, then i want to get 0,1,3,4,5 since i have 6 index inside

Answer 1

Through this , might you get your solution ,

In this JS script , you will not get the current index .

var arr = [1 , 2 , 3 , 4 , 5 , 6];

arr.forEach(function(valuw , index){
    console.log(valuw , index);
   for(var i = 0 ; i < arr.length ; i++){
    if( i != index){ 
    console.log("index at " , index , "itereator ===>" , i+1);
 }
}
});

Use Array.filter() to find the other indexes:

 const idxs = [0,1,2,3,4,5,6,7,8,9,10] const cur = 4 const res = idxs.filter(idx => idx !== cur) console.log(res)
