Question

I’m trying to insert a Gantt chart into the div container named ‘GanttDiv’. I’m using dhtmlxGantt library.

So, I downloaded this library and saved it in mod_gantt/js. Next, I copied a sample code just to check how it works. The problem is that a Gantt chart is not created on my web page.

What could be the reason?

<script type="text/javascript" language="JavaScript">
function createChartControl('GanttDiv')
{
    // Initialize Gantt data structures
    var project1 = new GanttProjectInfo(1, "Applet redesign", new Date(2010, 5, 11));
    var parentTask1 = new GanttTaskInfo(1, "Old code review", new Date(2010, 5, 11), 208, 50, "");
    parentTask1.addChildTask(new GanttTaskInfo(2, "Convert to J#", new Date(2010, 5, 11), 100, 40, ""));
    parentTask1.addChildTask(new GanttTaskInfo(13, "Add new functions", new Date(2010, 5, 12), 80, 90, ""));
    var parentTask2 = new GanttTaskInfo(3, "Hosted Control", new Date(2010, 6, 7), 190, 80, "1");
    var parentTask5 = new GanttTaskInfo(5, "J# interfaces", new Date(2010, 6, 14), 60, 70, "6");
    var parentTask123 = new GanttTaskInfo(123, "use GUIDs", new Date(2010, 6, 14), 60, 70, "");
    parentTask5.addChildTask(parentTask123);
    parentTask2.addChildTask(parentTask5);
    parentTask2.addChildTask(new GanttTaskInfo(6, "Task D", new Date(2010, 6, 10), 30, 80, "14"));
    var parentTask4 = new GanttTaskInfo(7, "Unit testing", new Date(2010, 6, 15), 118, 80, "6");
    var parentTask8 = new GanttTaskInfo(8, "core (com)", new Date(2010, 6, 15), 100, 10, "");
    parentTask8.addChildTask(new GanttTaskInfo(55555, "validate uids", new Date(2010, 6, 20), 60, 10, ""));
    parentTask4.addChildTask(parentTask8);
    parentTask4.addChildTask(new GanttTaskInfo(9, "Stress test", new Date(2010, 6, 15), 80, 50, ""));
    parentTask4.addChildTask(new GanttTaskInfo(10, "User interfaces", new Date(2010, 6, 16), 80, 10, ""));
    parentTask2.addChildTask(parentTask4);

    parentTask2.addChildTask(new GanttTaskInfo(12, "Task B (Jim)", new Date(2010, 6, 8), 110, 1, "14"));
    parentTask2.addChildTask(new GanttTaskInfo(14, "Task A", new Date(2010, 6, 7), 8, 10, ""));
    parentTask2.addChildTask(new GanttTaskInfo(15, "Task C", new Date(2010, 6, 9), 110, 90, "14"));
    project1.addTask(parentTask1);
    project1.addTask(parentTask2);

Make your javascript instantly runnable by adding the following script:

(function(){
        createChartControl('GanttDiv');
})();
