Creating The Interface
This is where we will create a simple interface for our application. This code will display a form select element and button. To create this simply copy and write it into your text editor, then save it as index.html.
Creating JavaScript Function
This is where the main function of the application is. This code will let you dynamically add new options into select list tag. To do this just copy and write these block of codes inside the text editor and save it as script.js.
In the code we will create a method called addSelectList(), this will be the only function we will needed to add options. In the first line of code inside the method we will create two variables, this two will only bind a selection element. Next we will add a conditional statement that will only prevent you to add a null value, otherwise it will continue to run the code.
In the next couple of code we create a variable that will create a new element called newOption, this will act a the parent node. Next is we create a variable that will set the value of the child element called newOptionValue. Within this two variable we just only append the child element value into the parent element in order to add new option in the select tag.
