这里我通过javascript将值传递给图表。但是我需要通过数据库将值传递给图形。我已经编写了一个代码来检索该值。名称是：Test2.zul

这里我想将Test2.zul中的值传递给Test1.zul，并且应该通过从数据库中获取值来绘制图形，即来自Test2.zul。 数据库值是：
ProjectName TotalTestCase TestCaseExecuted TestCaseFailed TestCaseNotExecuted
Project1 50 30 8 20
Project2 20 10 2 10
Project3 55 25 12 30
请告诉我如何继续。谢谢

您可以通过各种方式访问zscript中的组件，请参阅文档here或here。
例如，你可以简单地通过id引用组件，然后设置值，如下例所示：<window id="win_1">
<zscript><![CDATA[
win_1.title="given by zscript";
]]>
</zscript>
</window>
或者将zscript添加到组件并使用self：
<listbox>
<zscript>self.getItems();</zscript><!-- self is listbox -->
<listitem value="ab" label="${self.value}"/><!-- self is listitem -->
<zscript>self.getSelectedIndex();</zscript><!-- self is listbox -->
</listbox>
