    document.getelementbyid("plat").value = localstorage.latitude;     document.getelementbyid("plon").value = localstorage.longitude;      function fileselected() {                     var file = document.getelementbyid("fileupload").files[0];         if (file) {             var filesize = 0;             if (file.size > 1024 * 1024) {                 filesize = (math.round(file.size * 100 / (1024 * 1024)) / 100).tostring() + 'mb';             }             else {                 filesize = (math.round(file.size * 100 / 1024) / 100).tostring() + 'kb';             }              document.getelementbyid("filename").innerhtml = 'name: ' + file.name;             document.getelementbyid("filesize").innerhtml = 'size: ' + filesize;             document.getelementbyid("filetype").innerhtml = 'type: ' + file.type;         }     }      function uploadfile() {         var id = new formdata();         id.append("fileupload", document.getelementbyid("fileupload").files[0]);         var xhr = new xmlhttprequest();         xhr.upload.addeventlistener("progress", uploadprogress, false);         xhr.addeventlistener("load", uploadcomplete, false);         xhr.addeventlistener("error", uploadfailed, false);         xhr.addeventlistener("abort", uploadcancelled, false);         xhr.open("post", "snap.php");         xhr.send(id);     }      function uploadprogress(evt) {         if (evt.lengthcomputable) {             var percentcomplete = math.round(evt.loaded * 100 / evt.total);             document.getelementbyid("progressnumber").innerhtml = percentcomplete.tostring() + '%';         }         else {             document.getelementbyid("progressnumber").innerhtml = 'unable compute';         }     }      //==================================================================     // these events raised when server sends response     //==================================================================     function uploadcomplete(evt) {          alert(evt.target.responsetext);     }      function uploadfailed(evt) {         alert("therew error attempting upload file.");     }      function uploadcancelled(evt) {         alert("the upload has been cancelled user or browser dropped connection.");     } </script> </head> <body>      <div>     <form id="form1" enctype="multipart/form-data" method="post" action="scripts/snap.php">

       <p>             <input id="plat" type="text" value="" />             <input id="plon" type="hidden" value="" />         </p>         <div class="row">             <label for="fileupload">select image upload</label><br />             <input type="file" name="fileupload" id="fileupload" onchange="fileselected();" />         </div>         <div id="filename"></div>         <div id="filesize"></div>             <div id="filetype"></div>         <div class="row">             <input type="button" onclick="uploadfile()" value="upload" />         </div>         <div id="progressnumber"></div>     </form> </div> </body> </html>

try code calling script before dom content loads: 

    document.addeventlistener('domcontentloaded', function () {         document.getelementbyid("plat").value = localstorage.latitude;         document.getelementbyid("plon").value = localstorage.longitude;     }, false);       function fileselected() {         var file = document.getelementbyid("fileupload").files[0];         if (file) {             var filesize = 0;             if (file.size > 1024 * 1024) {                 filesize = (math.round(file.size * 100 / (1024 * 1024)) / 100).tostring() + 'mb';             }             else {                 filesize = (math.round(file.size * 100 / 1024) / 100).tostring() + 'kb';             }              document.getelementbyid("filename").innerhtml = 'name: ' + file.name;             document.getelementbyid("filesize").innerhtml = 'size: ' + filesize;             document.getelementbyid("filetype").innerhtml = 'type: ' + file.type;         }     }      function uploadfile() {         var id = new formdata();         id.append("fileupload", document.getelementbyid("fileupload").files[0]);         var xhr = new xmlhttprequest();         xhr.upload.addeventlistener("progress", uploadprogress, false);         xhr.addeventlistener("load", uploadcomplete, false);         xhr.addeventlistener("error", uploadfailed, false);         xhr.addeventlistener("abort", uploadcancelled, false);         xhr.open("post", "snap.php");         xhr.send(id);     }      function uploadprogress(evt) {         if (evt.lengthcomputable) {             var percentcomplete = math.round(evt.loaded * 100 / evt.total);             document.getelementbyid("progressnumber").innerhtml = percentcomplete.tostring() + '%';         }         else {             document.getelementbyid("progressnumber").innerhtml = 'unable compute';         }     }      //==================================================================     // these events raised when server sends response     //==================================================================     function uploadcomplete(evt) {          alert(evt.target.responsetext);     }      function uploadfailed(evt) {         alert("therew error attempting upload file.");     }      function uploadcancelled(evt) {         alert("the upload has been cancelled user or browser dropped connection.");     }

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
