How can I access object properties containing special characters?
I have a form DOM element:
var virDom = document.getElementsByTagName("form")[0];
virDom has two fields with IDs creditId and pwdId... I can access virDom.creditId without any issue, but virDom.pwdId.. is failing with a syntax error, because of the periods contained in the name.
How can I access such properties?
Solution 1:
Use bracket notation:
virDom['creditId']
virDom['pwdId..']
This applies to any object, and it is particularly useful for non-identifier-safe characters and also for accessing keys that you may not know ahead of time.
