Hi All
I want to drop a pin using data that is saved on to JavaScript Variables, x and y. How can I do that. Below is the code to drop a pin and get coordinates, is there a way I can change it so that I drop the pin using data that is saved on variables?

Hi Siyabonga Kubeka,
Recently, I did create a little app - with the ArcGIS API for JavaScript 4.x - with a custom tool to enter WGS84 Coordinates to zoom to a certain point, see screen capture attached.
These entries are used to create a new Graphic that is added to the MapView.
You can find (the source code of) the app here:
ArcGIS JavaScript Tutorial - Go to Latitude/Longitude
Is this useful to you?
Cheers,

Hi Egge-Jan Polle
Thank you very much, let me try that.
Hi Egge-Jan Polle
Can I please the .htm file? Please email to siyakubeka@live.com
Hi Siyabonga Kubeka,
Yes, of course! You can view the source in your browser, and copy the full .htm file from there.
You can access the source - both in Firefox and Google Chrome - by hitting Ctrl+U with the page open --> the source will then be opened in a separate window.
Did you know this trick already?
Cheers,
Egge-Jan
