Dynamically Populate Select Option List Value Using JavaScript Option Constructor

preview_player
Показать описание
Dynamically add select option list value depend upon select option value using javascript.

we trigger the callback function using addEventListener when change occurs in main options.
Get the selected value and corresponding value using object property calling method.
using while loop deletes the submenu option if there any previous option present.
later we convert the object property to array and loop through it.
using Option constructor which is developed specifically for option value change.

Javascript have inbuilt Options constructor would help us to create the option HTML element with desire value and inner Text.
after the we have to append the options to Select Element .

In video 5:05 convert is misspelled as conver.

thanks for watching the video. subscribe and support. Cheers!

Nice. How did you get VS Code to enter the value and placeholder at the same time when you were filling out the option fields / tags in your html page?

Hi @decoder, I have searched whole youtube but I couldn't find any video in which there are more than three menus. All of the videos are related to three menus including PHP, Jquery etc. Can you upload a video while training on how how to add more than three menus. lets say 4 or 5 dynamic dependent drop down menus?
