The SELECT control in Form does not support the sorting of options (option, I will sort the value attribute values in Option, and adjust the location after each Option sort, the specific code is as follows (here, it assumes Value in each Option) The same as the text content):
This function uses the sort method of the Array (array) object to achieve SELECT sorting.
Function Sortme (Osel) {var ln = osel.Options.Length; var arr = new array (); // This is a key part
// Put all the value values of all Option in the Select will be saved in the array (var i = 0; i / / If you need to sort the text in the Option, you can change to Arr [i] = osel.options [i] .text; arr [i] = osel.options [i] .value; } Arr.sort (); // Start sorting / / Clear all Option in SELECT While (ln -) {osel.options [ln] = null; // Re-add the sorted array to SELECT For (i = 0; i The following example demonstrates a SELECT in ascending order
