javascript - Jquery get image id of next element -


I have a list of images, I try to use Jquery to find the next image ID from the current element I am But I can not seem to work for Jquery 

  & lt; Div class = "grid" style = "position: relative;" & Gt; & Lt; Div class = "preview" & gt; & Lt; Img src = "1.jpg" id = "175" alt = "" & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "grid" style = "position: relative;" & Gt; & Lt; Div class = "preview" & gt; & Lt; Img src = "2.jpg" id = "176" alt = "" & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "grid" style = "position: relative;" & Gt; & Lt; Div class = "preview" & gt; & Lt; Img src = "3.jpg" id = "177" alt = "" & gt; & Lt; / Div & gt; & Lt; / Div & gt;

javascript 

  var childId = 6; $ (".grid") .click (function () {var image = $ (this) .find ("img"); var imageId = image.attr ("id") show_image (imageId, childId);}); The function show_image (imageId, childId) {// is required to get the next image ID in the group for the next button, but the code below undefined var next image = $ (".grid .preview #" + imageId) .next ("img") .attr ("id"); }

You can not use directly in .next () This case, because the images are not siblings for each other's use, 

  var nextImageId = $ ("#" + imageId) .closest (' Grid '). Next ("grid") appears ('img') attr ("id") ..

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...
