When using the code.org javascript editor in Applab, it is possible to create a dropdown menu by utilizing the following syntax:
dropdown('id', 'option1', 'option2', ...);
I am curious if there is a method to manipulate the dropdown list like an array, such as:
remove('id', 'position');
and:
insert('id', 'position', 'item1', 'item2'...);
Any assistance on this matter would be greatly appreciated, as I have been unable to find information on how to do this elsewhere.
To transform a dropdown into an array, utilize the getProperty method. Modify the array as needed and then convert it back to a dropdown using setProperty. Check out the following code snippet for reference:
dropdown("id", "a", "b", "c");
function editDropdown() {
var myDropdown = getProperty("id", "options");
//add an item to the dropdown.
appendItem(myDropdown, "e");
//remove an item from the dropdown.
removeItem(myDropdown, "a");
setProperty("id", "options", myDropdown);
}
editDropdown();
