coffeescript - Parsing AJAX response in callback -


i need access piece of data html response in ajax callback.

in coffeescript, want access completion-id data attribute. when following:

  $('.mark-completed')     .bind "ajax:success", (event, data) ->         console.log data         console.log $(data)

i in console data:

<li class="learning_item_completion" data-completion-id="162" data-user-id="2" id="learning_item_completion_162">   <div class="item-icon">     <img alt="thumb_alex_headshot_green_200x200" class="circular" height="60" src="/uploads/user/picture/2/thumb_alex_headshot_green_200x200.png" width="60" />   </div>   <div class="item">

and $(data):

[li#learning_item_completion_162.learning_item_completion, jquery: "1.9.1", constructor: function, init: function, selector: "", size: function…]   0: li#learning_item_completion_162.learning_item_completion   accesskey: ""   attributes: namednodemap   0: class   1: data-completion-id     ...     nodevalue: "162"     value: "162"     ...

what's right way access completion-id?

simply add :

$('.mark-completed') .bind "ajax:success", (event, data) ->     cid = $(data).find('.learning_item_completion').data('completion-id')     console.log cid

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
