我正在尝试添加一个下拉框菜单，我将在其中做出选择以可视化数据。如果没有下拉框，我的可视化效果很好，但是当我将它们放在一起时出现问题。在我的代码中，我想在选择 selection02 时可视化数据。有人可以帮我吗？

function allagi()

   if (document.getElementById("selection01").selected==true)
   {
      function01();
   }
   else if (document.getElementById("selection02").selected==true)
   {
      f1();
   }
   else if (document.getElementById("selection03").selected==true)
   {
      function03();
   }
   else if (document.getElementById("selection04").selected==true)
   {
      function04();
   }
}

这只是一个技巧......它可以按照你的意愿工作......但我相信应该有更好的方法......对不起，如果我没有帮助......

我相信您编写的 JavaScript 在语法上是无效的。

您已经编写function f1() { "string" }了“字符串”看起来像 JSON 字符串的地方。我认为您打算编写代码来调用将这个字符串作为参数传递的函数，但我不知道您正在使用的服务的语法。

<script type="text/javascript" src="//ajax.googleapis.com/ajax/static/modules/gviz/1.0/chart.js"> 
function f1(){
 {"dataSourceUrl":"//docs.google.com/spreadsheet/tq?key=0AihqKzH-MgAndERnaFVsYk1RLUM3S0pDSmNjcEQ4M1E&transpose=0&headers=0&range=A2%3AB13&gid=0&pub=1","options":{"vAxes":[{"useFormatFromData":true,"viewWindowMode":"pretty","viewWindow":{}},{"useFormatFromData":true,"viewWindowMode":"pretty","viewWindow":{}}],"booleanRole":"certainty","animation":{"duration":0},"useFirstColumnAsDomain":true,"hAxis":{"useFormatFromData":true,"viewWindowMode":"pretty","viewWindow":{}},"isStacked":false,"width":454,"height":285},"state":{},"chartType":"AreaChart","chartName":"\u0393\u03c1\u03ac\u03c6\u03b7\u03bc\u03b1 1"}
