Infovis JIT library

Question

我正在使用"JavaScript Infovis"工具包，"SpaceTree控件"适合需要数据可视化。

我使用"jQuery"来调用"Ajax"来动态加载数据到树中。这棵树装得很好。但是，当我单击任何节点时，我得到以下错误消息:

画布未定义

我从我的aspx页面调用这个Javascript库:

$j(document).ready(function() {            
    var aURL = 'CompanyHierarchyList.ashx?CompanyID=<%=CompanyID %>';
    $j.ajax({
        url: aURL,
        cache: false,
        dataType: 'json',
        success: function(json) {
            LoadTree(json);
        }
    });
});

var st = new $jit.ST({
    //id of viz container element
    injectInto: 'infovis',
    //set duration for the animation
    duration: 200,
    //set animation transition type
    transition: $jit.Trans.Quart.easeInOut,
    //set distance between node and its children
    levelDistance: 50,
    //set Orientation
    orientation: 'top',
    //.....
    //set the other properties of node
    //.......
    st.loadJSON(json);
    //compute node positions and layout
    st.compute();
    //optional: make a translation of the tree
    st.geom.translate(new $jit.Complex(-200, 0), "current");
    //emulate a click on the root node.
    st.onClick(st.root);
    //end
}

. .

任何线索

谢谢,恋人
