Accessing SharePoint list with JavaScript Variable Storage -


i started yesterday javascript , i'm trying information sharepoint 2010 list , want print table. following code in body tag:

<script type="text/javascript">     executeordelayuntilscriptloaded(mainfunction, "sp.js");     var typenumber = "1520";     var statusarray = new array(3);     try {         function mainfunction() {             var clientcontext = new sp.clientcontext.get_current();             var olist = clientcontext.get_web().get_lists().getbytitle('projektstatus');              //empty query string cause there problems lookup field             var emptycamlquery = new sp.camlquery();              this.colllistitem = olist.getitems(emptycamlquery);             clientcontext.load(colllistitem);             clientcontext.executequeryasync(function.createdelegate(this, this.onquerysucceeded), function.createdelegate(this, this.onqueryfailed));             document.write(statusarray[2]);         }          function onquerysucceeded(sender, args) {             var listiteminfo = '';             var = 0;             var listitemenumerator = colllistitem.getenumerator();             while (listitemenumerator.movenext()) {                 var olistitem = listitemenumerator.get_current();                 if (olistitem.get_item('title').match(typenumber)) {                     statusarray[i] = olistitem.get_item('kpi_status');                      //works fine                     alert("nummer:" + + statusarray[i]);                      i++;                 }             }         }         function onqueryfailed(sender, args) {             alert('request failed. ' + args.get_message() + '\n' + args.get_stacktrace());         }          var tableoutput = "<table><tr><th>indikatortyp</th><th>kpi-status</th></tr>" +                         "<tr><td>kosten</td><td>" + statusarray[2] + "</td></tr>" +                         "<tr><td>technik</td><td>" + statusarray[1] + "</td></tr>" +                         "<tr><td>termin</td><td>" + statusarray[0] + "</td></tr>" +                     "</table>"         document.write(tableoutput);     } catch (e) {         alert(e);     } </script>

the output alert works fine when want print statusarray in table doesn't work cause variable undefined. think problem createdelegate().

the problem because use global variable statusarray , code create table outside onquerysucceeded.

my suggestions are: - encapsulate statusarray variable - move creation of table inside onquerysucceeded

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 ...
