javascript - characters inserted after cursor firefox -


I'm trying to create a WYSIWYG editor. At some point I need to change the position of the cursor. I use this code for that purpose: 

  var sel = window GetSelection (); Var range = document.createRange (); Range.setStart (startNode, startoffset); Range .setEnd (endnode, endoffet); Sel.removeAllRanges (); Sel.addRange (range);

A new condition is expected, however, when I start typing the text, it appears after the cursor, and vice versa. For example if I type test then it is | Tset looks like .

This bug occurs in Firefox 31.0, while it is working fine in Chrome Do you know what might be the reason for this bug and how to fix it?

Edit:

I came to know how to fix it: The problem came from the fact that element startNode The bug that was not fixed could be fixed like this: 

  var sel = window.getSelection (); Var range = document.createRange (); Range.setStart (startNode, startoffset); Range .setEnd (endnode, endoffet); $ (StartNode) .focus (); Sel.removeAllRanges (); Sel.addRange (range);

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!
