javascript - Fotorama - different captions based on if element has attribute -


I am trying to create a custom photo caption caption, depending on whether IMG has a data-title attribute or not. Right now, it is currently being displayed as "undefined", but I would like to completely leave that feature if it is not there. I tried to use the statements / else and tried to verify whether the IMG element has this feature or not, but to no avail. I'm not able to use the "div" floatma approach because I need the gallery and accordingly the size images

How does this look like my image tag: 

  & lt; Img src = "images / whatever.jpg" data-caption = "brief description goes here." Data-writer = "additional details here" data-title = "http://www.link.com" range = "0" & ​​gt;

The code I'm using to create this custom character format is: 

  $ ('. Fotorama') .on ('fotorama: show ', Function (E, FORTAMA) {FONTMA. $ Caption = PHOTARMA. $ Caption || $ (this) .NEWXT (' example 'Blurb'); var ActiveFrame = Fasterma ActiveFamma; Fotma. Caption. Html (' Lt; p & gt; & lt; em & gt; '+ activeFrame.caption +' & lt; a target = "_ blank" href = "'+ activeframe. Title +'" & gt; (link) & lt; / A & gt;   & lt; p & gt; '+ activeFrame.author +' & lt; / p & gt; ');}) Foremosta ();

And likewise, I want to read captions whether there is no data-titled feature on the div: 

  '& lt; P & gt; & Lt; Them & gt; '+ ActiveFrame.caption +' & lt; / Em> & Lt; / P & gt; & Lt; P & gt; + ActiveFrame.author + '& lt; / P & gt;

Thanks advance!

An alternative solution for this is to use CSS if someone else is having the same problem. If I struggle with creating ... and on the basis of the caption, how the data-title attribute is defined or not, but for some reason it does not seem to check each activeframe whether it has data The title is characteristic or not - only the first plugin can have an underlying issue or ignore me.

Anyway, the solution!

I have created a new property on each IMG tag ("data-class"), which would be either "work_link" or "no_link" value: 

  & lt ; Img src = "images / whatever.jpg" data-caption = "brief description goes here." Data-writer = "additional details here" data-title = "http://www.link.com" data-class = "function_link" range = "0" & ​​gt; & Lt; Img src = "images / whatever.jpg" data-caption = "brief description goes here." Data-writer = "additional details here" data-square = "no_link" range = "0" & ​​gt;

I changed the caption HTML in the script to read like this - Essentially link either the "work_link" or "no_link" class: 

 < Code> Fortama $ Caption.html ('<<> & lt; em>' + activeFrame.caption + '& lt; a class = "' + activeframe.clus +" "target =" _ blank "href = "'+ ActiveFrame. Title +'" & gt; (link)   
 '+ activeFrame Author + '& lt; / p & gt;');

And finally the "work_link" class is not displayed in the original styling CSS and "no_link" class. 

  .work_link {margin-left: 12px;} .no_link {display: none;}

Probably the best way to do this, but like a charm Works!

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
