showing the possible Routes

PhuongNguyen_Thanh

Hi everybody ! I'm doing a map that when I click on the map and it will show us possible routes can go in 5 or 10 minutes. But I'm getting stuck that it's not drawing something on a map.

Here's my code

Please help me to find out where i was wrong or missing something to improve my map. Your help will be my best motivation.

Thank you for your reading time. I hope you will have a lucky day with your work 🙂 🙂 🙂 !!!!

Dear Ciava,

You are my savior 🙂 🙂 many many thanks to you

.

And by the way, can you guide me how to automatically show all the routes or points that we can go in 10 minutes by car when we open a web map (I use "onload" function and serviceAreaTask)

Thank you,

Phuong Nguyen
