Can jQuery differentiate between a regular array, an array of arrays, and an array of objects?
var a = [1,2,3];
var a2 = [[12,'Smith',1],[13,'Jones',2]];
var a3 = [{val:'12', des:'Smith', num:1}];
//a = regular array
//a2 and a3 = multidimensional arrays
What is the best way to achieve this? Appreciate any help you can provide.
If jQuery is your tool of choice, you have the option to utilize this syntax:
$.isArray(a[0]);
For more information on this method, refer to the official documentation: http://api.jquery.com/jquery.isarray/
Keep in mind that there are alternative approaches available. In pure JavaScript, a similar check can be performed using:
Array.isArray(v[0]);
An efficient method for examining the structure of an array:
function isMultiDimensional(array) {
return array.some(element => Array.isArray(element))
}
This function effectively determines if any element within the array is also another array.
If you are working with multidimensional arrays where all elements are arrays, please refer to the alternative solutions provided by other contributors.
This method offers a solution to your issue
function analyzeArray(inputArr){
if(!Array.isArray(inputArr[0])) return 'basic array';
else return 'Complex array [Array of arrays (or) Array of objects]';
}
analyzeArray(arr); // basic array
analyzeArray(arr1); // Complex array [Array of arrays (or) Array of objects]
