Is the bottom of your canner flat or wavy? That style is usually wavy (it’s made to work with gas burners) and you’ll have issues with the time it takes to boil water on a flat surface element. The main issue,afaik, is getting the water back to a boil after you put your jars in. Another issue is how much weight your glass top can handle. A canner full of water and jars is quite heavy. One solution is to use a propane burner (like for a turkey fryer) on your porch if possible. I ended up purchasing a canner specifically for flat burners. Here’s a link:

If the top can handle the weight of a full canner (check the user guide/specifications) then you will need a flat bottom pot. A pot with ridges/uneven bottom will lead to pockets of hot air and that will crack the glass. I use the harvest water bath canner on my glass top induction stove.
If your glass top can handle the weight of a full canner, you need a flat bottom pot. Air gaps will cause super heated air pockets and will crack the top. I use this on my induction stove.
I didn't notice any uneven heating when I water bath canned with the ridged bottom, but then again I wasn't looking for it either. I figured "Well, it's boiling" and left it at that. It was probably unwise of me to not look for heating issues.
My current steam canner has a flat bottom so that issue is eliminated entirely:
