this is a very cool, lightweight, jquery plugin jQuery.ganttView which is easy to use and fast. Currently it was working in our first version of system.

Unfortunately it turned out that system needs some functionalities that ganttView doesn’t provide, witch were:

  • Paging
  • Multiple tasks per row
  • Parse json date stored in ticks format (milliseconds since January 1, 1970)

At first I wanted to extend used plugin but because I had some free time and wanted to learn new skills I’ve decided to write my own jquery plugin.

Plugin uses data in JSON formated as below:

    [{ "name": "Jan Kowalski",
    "desc": "Programista",
    "values": [
    {
    "from": "/Date(1309471200000)/",
    "to": "/Date(1310421600000)/",
    "desc": "Type: Task
    name: Task 1
    Description: Task desc."
    },
    {
    "from": "/Date(1310594400000)/",
    "to": "/Date(1311112800000)/",
    "desc": "Type: Task
    name: Task 2
    Description: Task desc.",
    "customClass": "ganttOrange"
    }
    ]
    },
    ...
    { "name": "Jan Nowak",
    "desc": "Serwisant",
    "values": [
    {
    "from": "/Date(1311544800000)/",
    "to": "/Date(1312581600000)/",
    "desc": "Type: Task
    name: Task 40
    Description: Task desc.",
    "customClass": "ganttRed"
    },
    {
    "from": "/Date(1312322400000)/",
    "to": "/Date(1312754400000)/",
    "desc": "Type: Task
    name: Task 41
    Description: Task desc."
    }
    ]
    }]
