Change polygon fillColor with javascript (google maps) -


i'm trying change google maps polygon fillcolor on click. here code => https://jsfiddle.net/nw6j52f6/

Аnd here problem part of code. function should change design of polygons:

function polyopt(i) { setoptions({     strokecolor: '#ff0000', strokeopacity: 0.8,     strokeweight: 3, fillcolor: '#ff0000', fillopacity: 0.35 }); }

but console return error:

map-array.html:56 uncaught referenceerror: setoptions not defined @ polyopt (map-array.html:56) @ htmlinputelement.onclick (map-array.html:69)

i'm using google maps api https://developers.google.com/maps/documentation/javascript/reference#polygonoptions

but don't understand why console show error.

if polygon i must use i.setoptions

function polyopt(i) {    i.setoptions({     strokecolor: '#ff0000', strokeopacity: 0.8,     strokeweight: 3, fillcolor: '#ff0000', fillopacity: 0.35 });

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
