javascript - For var in object returns methods together with properties -


I have tried the following code and am surprised to know that Object Returns for Verdes in the ORIID also objects I'm not sure Why does this happen, do objects are essentially properties? Does there a quality in it that it returns only properties with properties? 

  var object = {p1: 1, p2: 2, p3: 3}; Object.funkcja = function () {for (var x in object) {document.getElementById ("test"). Internal HTML + = Object [x] + "& lt; BR & gt;";}};

Example:

I think this is the right way : (Object isOwnProperty (x) & amp; (function [x] function for example) {document.getElementById ("test") 

  internal HTML + = object ] + "& Lt; BR & gt;"; }}

java - Joda Time Interval Not returning what I expect -

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
