Changing combo box options dynamically with javascript

Most of you guys might already have known about this. I have a requirement where I have to change the options of a combo box when i choose either “Hourly” or “salaried” in another combo box.

A new Option can be created using

var newOption = new Option(“text”, “value”);

Options can be accessed using the select that created the combo box

Where this code will select “ExcludeHoliday” combo box and the first option. When we try to remove an option from the middle it is essential to reorganize the list starting for the removed option. To mention, removing an option is to set the value of that option to “null” :)
