我对创建GanttChart很感兴趣。经过长时间的搜索，我找到了"dhtmlxGantt">
http://www.dhtmlx.com/docs/products/dhtmlxGantt/index.shtml
我在中尝试了dhtmlxGantt的示例
http://www.dhtmlx.com/docs/products/dhtmlxGantt/download/dhtmlxGantt.zip
我现在的问题是，当我尝试运行我的应用程序时，dhtmlxGantt会给我一个空白页，因为它无法从javascript文件中获取一些函数！
这是我的代码：

有人能帮我吗？
您在某处调用createChartControl函数吗？我在代码中看不到。尝试添加：
<script type='text/javascript'>
createChartControl('GanttDiv');
</script>
定义函数和div之后。
