How can I sort an array of arrays by the second element which is also an array that contains only one element?
For example, the following array
array = [
["text", ["bcc"], [2]],
["text", ["cdd"], [3]],
["text", ["aff"], [1]],
["text", ["zaa"], [5]],
["text", ["d11"], [4]]
];
Should be sorted as follows:
sorted_array = [
["text", ["aff"], [1]],
["text", ["bcc"], [2]],
["text", ["cdd"], [3]],
["text", ["d11"], [4]],
["text", ["zaa"], [5]]
];
You should use .sort() method which accepts a callback function.
Also, you have to use .localeCompare method in order to compare two strings.
array = [
["text", ["bcc"], [1]],
["text", ["cdd"], [1]],
["text", ["aff"], [1]],
["text", ["zaa"], [1]],
["text", ["d11"], [1]]
];
var sortedArray=array.sort(callback);
function callback(a,b){
return a[1][0].localeCompare(b[1][0]);
}
console.log(sortedArray);
You can use sort() method like this.
var array = [
["text", ["bcc"], [1]],
["text", ["cdd"], [1]],
["text", ["aff"], [1]],
["text", ["zaa"], [1]],
["text", ["d11"], [1]]
];
var result = array.sort((a, b) => a[1][0].localeCompare(b[1][0]))
console.log(result)
You can achieve it by passing compared child level array in array sort function
array = [
["text", ["bcc"], [1]],
["text", ["cdd"], [1]],
["text", ["aff"], [1]],
["text", ["zaa"], [1]],
["text", ["d11"], [1]]
];
function Comparator(a, b) {
if (a[1] < b[1]) return -1;
if (a[1] > b[1]) return 1;
return 0;
}
array = array.sort(Comparator);
console.log(array);
Hope it helps
You could sort the nested elements with String#localeCompare.
var array = [["text", ["bcc"], [2]], ["text", ["cdd"], [3]], ["text", ["aff"], [1]], ["text", ["zaa"], [5]], ["text", ["d11"], [4]]];
array.sort(function (a, b) {
return a[1][0].localeCompare(b[1][0]);
});
console.log(array);.as-console-wrapper { max-height: 100% !important; top: 0; }(Only for modern JavaScript engines)
array.sort(([,[a]], [,[b]]) => a.localeCompare(b))
You can do:
array.sort(function(a, b) {
if (a[1][0] > b[1][0])
return 1;
else if (a[1][0] < b[1][0])
return -1;
return 0;
});
['bcc']or with the number [2]?['bcc']for example
