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???"**);推荐答案

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