Answer 1

Your code is executing like this:

temp = "title" || "amount"; // two "true" values, so "title" is assigned
if (field.name == temp);{ ... };

which is effectively:

temp = "title";
if (field.name == temp) { ... }

To test one varaible against multiple strings, you have to write out the individual tests directly:

if ((field.name == "title") || (field.name == "amount")) { ... }

and if you need to test against MANY items for which this kind of stuff would get tedious, you can try an array:

if (["title", "amount", ...].indexOf(field.name) > -1) { ... }
