javascript - setAttribute makes the attribute name lowercase - Stack Overflow

I create elements with the var l = document.createElement("label"); and I assign its attributes with l.setAttribute("formControlName","e");. The problem is that the setAttribute method puts the formControlName in lowercase letters as you can see in the image below. I work with ionic so the capital letters are needed. Does anyone see what I did wrong?

• 1 Do you have a reference for "ionic so the capital letters are needed"? I find that hard to believe. – Nickolay Commented Jan 23, 2018 at 16:37
• This is rather a requirement of Angular which is a framework below Ionic. – mvermand Commented May 8, 2020 at 7:20

Use this instead:

l.setAttributeNS(null, "formControlName","e");

'setAttributeNS()' doesn't convert the name to lower case.
