I have 2 arrays, where the first array has keys and the second array is a multi-dimensional array with values.
Is there any pre-defined function in Javascript or jQuery which will give me the values in descending order by passing a key?
I have a solution, but I feel that it is a more costly approach. If anybody has better solution please let me know.
My current solution is -- get the index from the first array and loop through the second array and create a temporary array and then sort that temp array and use it.
You don't need to create a temporary array. Once you get the index of the attribute you're looking for (and for this example I shall assume it's in a variable called index
and that the whole JSON object is in jsondata
), just a simple sort
will do:
jsondata.rows.sort(function(a,b) {
return a[index]-b[index];
});
And there you have your sorted array.
