Answer 1

You are using = (assignment) instead of == (comparison).

if (connectiontype == 'red') {
    ...
} else if (connectiontype == 'green') {
    ...
}

When you have an assignment, eg: lhs = rhs the whole expression returns whatever rhs is. So:

if (connectiontype = 'red') { ...

// is equivalent to (as far as the "if" is concerned):

if ('red') { ...  

Since 'red' (a non-empty string) is "truthy" in JavaScript, the if is always true and your html variable will always be set to 'Red'.
