Checking the Web Part page design mode
The first tip is about detecting the web part page edit mode. Frequently, we write scripts to manipulate UI of the page and if the user is already editing the page, our script can cause undesired behaviour.
We could either execute a different set of functions or at a minimum, just not execute the script in design mode to keep the user experience clean.
It’s relatively simply to detect the WebPart page design mode. Just add the following code to the startup your script.
In the next part of this series, I’ll talk about how we can detect if a Project Details Page is in Edit mode.
