我尝试将我的第一个饼图作为表格上的输入数据并将数组传递给 html 文件，以便饼图可以检测数组并自行绘制，但现在的问题是它没有显示我输入的正确数据。它只会将全局变量跟踪为 (' ') nothing 而不是 i 输入的那个。抱歉编码太长了，我还是新手，这是我知道如何创建表格的唯一方法。

我没有仔细阅读您的所有代码（太多了），但我确实注意到您这样做了：

webview.addEventListener('beforeload',function(e)
{
     earn[0] = textfield1.value;
    earn[1] = textfield2.value;
    earn[2] = textfield3.value;
    earn[3] = textfield4.value;
    earn[4] = textfield5.value;

   wbv1.evalJS("var earn[0] ='"+earn[0]+"';");
   wbv1.evalJS("var earn[1] ='"+earn[1]+"';");
   wbv1.evalJS("var earn[2] ='"+earn[2]+"';");
   wbv1.evalJS("var earn[3] ='"+earn[3]+"';");
   wbv1.evalJS("var earn[4] ='"+earn[4]+"';");
});

在事件被触发之前，您不能在 webview 上调用 evalJS load，evalJS 仅在有一个带有 DOM 的页面首先加载时才有效，所以这不会做任何事情。您只需要在事件上调用 evalJS load。
