[Javascript] Sort alphabetically the option elements of a select element by text.

sortSelectOption.js

function sortSelectOptions(selectElement) {
	var options = $(selectElement + " option");

	options.sort(function(a,b) {
		if (a.text.toUpperCase() > b.text.toUpperCase()) return 1;
		else if (a.text.toUpperCase() < b.text.toUpperCase()) return -1;
		else return 0;
	});

	$(selectElement).empty().append( options );
}

good and easy solution :) Thanks!

i can't understand , please i have a select of countries , any help ?

Didn't work for me, but this works - maybe the snippet is for older jquery

var options = $(selectElement + " option").toArray();
options.sort(function(a, b) {
  let aa = a.textContent;
  let bb = b.textContent;
  if (aa.toUpperCase() > bb.toUpperCase()) return 1;
  else if (aa.toUpperCase() < bb.toUpperCase()) return -1;
  else return 0;
});
$(selectElement).empty().append( options );

perfect

Good

In 2024 please simply use a.textContent.toLocaleUpperCase().localeCompare(b.textContent.toLocaleUpperCase()) instead of this if else stuff
