To remove the options of an HTML element of select
, you can utilize the remove()
method:
function removeOptions(selectElement) {
var i, L = selectElement.options.length - 1;
for(i = L; i >= 0; i--) {
selectElement.remove(i);
}
}
// using the function:
removeOptions(document.getElementById('DropList'));
It’s important to remove the options
backwards; as the remove()
method rearranges the options
collection. This way, it’s guaranteed that the element to be removed still exists!
