#1888:
Backend changes:

  • Simplified job state detection (only one hive call will be made to detect all states now, instead of one additional call per job)
  • Reorganized classes (moved model classes into Model folder)

Website changes:

  • Website now heavily uses JavaScript to achieve better user experience
  • JavaScript degrades gracefully, except for plots
  • Tables: Added jquery-datatable-plugin to extend tables (pagination + search functionality)
  • OaaS-Website now uses the design of the HL websites (found in WebApplication branch)
  • Added jqplot to render zoomable line plots for HL-Datatables
  • Styling.js: Plots will be generated by using an ajax call; additional jquery-styling occurs within this file.
  • Added jquery-ui-1.9.2 which is capable of handling/rendering tabs, accordions and resizers.

32     * Class: $.jqplot.ciParser
33     * Data Renderer function which converts a custom JSON data object into jqPlot data format.
34     * Set this as a callable on the jqplot dataRenderer plot option:
35     *
36     * > plot = $.jqplot('mychart', [data], { dataRenderer: $.jqplot.ciParser, ... });
37     *
38     * Where data is an object in JSON format or a JSON encoded string conforming to the
39     * City Index API spec.
40     *
41     * Note that calling the renderer function is handled internally by jqPlot.  The
42     * user does not have to call the function.  The parameters described below will
43     * automatically be passed to the ciParser function.
44     *
45     * Parameters:
46     * data - JSON encoded string or object.
47     * plot - reference to jqPlot Plot object.
48     *
49     * Returns:
50     * data array in jqPlot format.
