The problem with something like the desired approach:
if (option.name == "Option1") {
is that 'name' is a valid key, so if you had an object like
{'name':'john'}
option.name would equal 'john' (same problem if you tried option.key).
Also, though your example only has one key, an object can have mutiple
keys.
Easiest way is just loop through the keys (fast since there's only one
key/value pair in your object):
$.each(JSON.options, function(i, option) {
for(k in option) {
if(k === 'Option1'){
// do something
}
}
});
