Contenteditable / jQuery / Javascript - Select text from cursor / caret to end of paragraph -


i'm trying make new paragraph when enter key pressed. can , works well. cursor middle of paragraph - when enter pressed i'm trying select range cursor position end of paragraph. remove existing paragraph , add new paragraph below.

i'm trying modify code found in answer here: contenteditable - extract text caret end of element

$(document).on('keydown', 'p[contenteditable="true"]', function(e) {     if(e.which == 13) { //new paragraph on enter/return         e.preventdefault();         var sel = window.getselection();     if (sel.rangecount) {         var selrange = sel.getrangeat(0);         var blockel = selrange.endcontainer.parentnode;         var range = selrange.clonerange();             range.selectnodecontents(blockel);             range.setstart(selrange.endcontainer, selrange.endoffset);             remainingtext = range.extractcontents();         $(this).after('<p contenteditable = "true">'+ remainingtext +'</p>');         $(this).next('p').focus();      }

i haven't had success - due lack of understanding when comes range, node , selection objects. able explain how these objects work , how can adapt answer above suit situation.

http://jsfiddle.net/uu4cg/17/

here's code adapted another answer remove rangy dependency:

var sel = window.getselection(); if (sel.rangecount > 0) {     // create copy of selection range work     var range = sel.getrangeat(0).clonerange();      // containing paragraph     var p = range.commonancestorcontainer;     while (p && (p.nodetype != 1 || p.tagname != "p") ) {         p = p.parentnode;     }      if (p) {         // place end of range after paragraph         range.setendafter(p);          // extract contents of paragraph after caret fragment         var contentafterrangestart = range.extractcontents();          // collapse range after paragraph         range.setstartafter(p);         range.collapse(true);          // insert content         range.insertnode(contentafterrangestart);          // move caret insertion point         range.setstartafter(p);         range.collapse(true);         sel.removeallranges();         sel.addrange(range);     } }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
