在Javascript中查找多维数组的索引
问题描述：
我在JavaScript中创建了一个多维数组，我想找到具体值的确切索引。该值将是用户输入。
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(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???"**);

/**
* 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] + '].');
