我在 JavaScript 中创建了一个多维数组，我想找到特定值的确切索引。该值将是用户输入。
var array = [];
var k = 0;
for (var i = 0; i < 10; i++) {
array[i] = [];
for (var j = 0; j < 100; j++) {
k = k + 1
array[i].push(k);
}
}
var index = array.indexOf(`**"What to insert here???"**`);
JSFiddle https://jsfiddle.net/wao20/Lct1de56/
/**
* Index of Multidimensional Array
* @param arr {!Array} - the input array
* @param k {object} - the value to search
* @return {Array}
*/
function getIndexOfK(arr, k) {
for (var i = 0; i < arr.length; i++) {
var index = arr[i].indexOf(k);
if (index > -1) {
return [i, index];
}
}
}
// Generate Sample Data
var k = 0;
var array = [];
for (var i = 0; i < 10; i++) {
array[i] = [];
for (var j = 0; j < 100; j++) {
k = k + 1;
array[i].push(k);
}
}
var needle = 130;
var result = getIndexOfK(array, needle);
console.log('The value #' + needle + ' is located at array[' + result[0] + '][' + result[1] + '].');
