javascript - angular - How can jQuery inside a custom directive respond to a $scope change? -


How can jQuery react to a $ scope change in a custom command? 

  & lt; Div id = "wrapper" Scrolled Directive & gt; & Lt; Div id = "scroller" & gt; Hello this is a test & lt; Div & gt; & Lt; / Div & gt;

Note: $ timeout is only instructed to push .scrollTop () at the end of the update cycle according to this thread 

  myapp.directive ($ 'Timeout') {return: 'a', link: function (scope, element, ethers) {$ timeout (function () {$ (element) .scrollTop ('scalddiakiev', function (timeout), function ($ 'timeout') Scope.mytop);}, 1);}};});

And at the end, some $ scope codes I want to direct on 

  $ scope.mytop = 500; $ Timeout (function () {$ scope.setPosition (50);}, 1000); $ Scope.setPosition = Function (Arg) {$ log.log ('=== & gt;', Arg); $ Scope.mytop = Arg; $ Scope $ apply () .; // ??? }

Edit:

This is a JSfield with all the minimum code to run. Unfortunately jsFiddle's UI adds its scrollbar to the panel, with this Interferes! Grr But leas have all the code on it if you feel like copying it. did not listen back to Ian (see comments), but what she said inspires me to solve

. I have posted a workgroup code here 

  area. $ Watch ('variableName', function () {//});

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
