For example, the following rewrote the get and set function of x1, excuse me, here the problem of red, how to implement? :



Object. DefineProperty (_value_test prototype, "x1", {
Get: the function () : number {
Return this. Xx + 1;
},
Set: function (value: number) {
If (value=0) https://bbs.csdn.net/topics/={
This. Xx=value + 1;
} else {

call here the original set function assignment, how to achieve here??????????? (don't copy the code method)

}

}
});

Found,

"_x1_set" _value_test. Prototype []=_value_test. Prototype [] "__lookupSetter__" (" x1 ");
"_x1_get" _value_test. Prototype []=_value_test. Prototype [] "__lookupGetter__" (" x1 ");
