Question

function sortDropDownListByText(selectId) {
    $(selectId).html($(selectId + \" option\").so         


        

Answer 1

First you have to preserve the selected value, and once you finished the sorting you re-select the preserved value.

#store the selected value.
var selectedVal = $(selectId).val(); 

# start sorting.
$(selectId).html( $(selectId+" option").sort(function(a, b) {
       return a.text == b.text ? 0 : a.text < b.text ? -1 : 1
    }));

#re-select the preserved value.
$(selectId).val(selectedVal);
