如何将JavaScript原型方法覆盖到我的普通JavaScript文件中？

Question

I have one method in JavaScript file which is written in prototype:

SMRangePickerCtrl.prototype.rangeSelected = function (range) {      

    var self = this;
    self.onRangeSelect({range: range});
    self.value = { startDate: range.startDateAsMoment, endDate: range.endDateAsMoment, __$toString: range.text };  
};

Now, I want to inherit this method in the separate JavaScript file.

How can I do it?

Answer 1

Something like this?

var myMethod = SMRangePickerCtrl.prototype.rangeSelected;
myMethod(range);

If you need to add this method to some other object use the following:

myObj.rangeSelected = SMRangePickerCtrl.prototype.rangeSelected.bind(myObj);

Or if you have an instance of SMRangePickerCtrl class say myAnotherObj and want to override this method use:

myAnotherObj.rangeSelected = function(range) {
...
}

Or if you want to replace the method for all instances of SMRangePickerCtrl just use:

SMRangePickerCtrl.prototype.rangeSelected = function (range) {      
// My implementation here
};
