Hi,

I was using document.getElementById("myid").innerHTML = "some html code"

After the migration to version 9, this is not working anymore and throw the error

TypeError: Cannot set property 'innerHTML' of null

As the goal is to set HTML, what is the workaround?

Regards,

First of all this is unsupported code in CRM as it’s directly doing DOM manipulation.

Verify if the passing “myid” or any other actual schema name is valid.

Check if the control with name is present or not before accessing its properties. For ex:

if(document.getElementById("myid") != null) document.getElementById("myid").innerHTML = "some html code";

Is it inside custom HTML? or you are referencing CRM OOB field?

If you are using custom HTML , it might be the reason that your script runs before all DOM has been loaded, when you trying to get element which isn't parsed yet that's why you get error. If you are using custom HTML place your script tags after body closing tag thats ensures that whole document has been already parsed when the script starts executing.

Hi,

This is one of the reason why you shoundn't be using the unsupported code. During the upgrade Microsoft can change the id of the elements and which is it seems happened here. Try to find the supported way of doing what you are currently doing. If there is no supported way and you still want to do use the current code then verify if the id is still same for the element post upgrade?

Hope this helps.

The history is that in the previous version the element was not hidden in the DOM, so I can hide it with HTML. In the version 9, the element was really hidden in the DOM and was not accessible anymore in HTML and of course, the error was thrown. Thank you for your help.
