To find Index of Multidimensional Array in Javascript

Question

I have created a multidimensional array in JavaScript and I want to find the exact index of specific value. That value will be user input.

var array=[];
for(         


        

Answer 1

this example seems to work well also with IRREGULAR multidimentional array:

function findIndex(valueToSearch, theArray, currentIndex) {
    if (currentIndex == undefined) currentIndex = '';
        if(Array.isArray(theArray)) {
            for (var i = 0; i < theArray.length; i++) {
                if(Array.isArray(theArray[i])) {
                    newIndex = findIndex(valueToSearch, theArray[i], currentIndex + i + ',');
                    if (newIndex) return newIndex;
               } else if (theArray[i] == valueToSearch) {
                   return currentIndex + i;
               }
            }
    } else if (theArray == valueToSearch) {
        return currentIndex + i;
    }
    return false;
}

var a = new Array();
a[0] = new Array(1, 2, 3, 4, 5);
a[1] = 'ciao';
a[2] = new Array(new Array(6,7),new Array(8,9),10);

var specificIndex = findIndex('10', a);

i wrote this speedly so everyone is invited to improve this function!

p.s. now the function returns a STRING value with all indexes separated by comma, you can simply edit it to returns an object
