Question

请查看IndexQ3文件中的SPOT 1评论。这就是我遇到问题的地方。当用户点击“下一个问题”按钮时xxx() 执行并运行myFunc_3。后者有一些我无法检测的问题，即使它是一个5行函数。我知道它是通过在电子表格中输入新值来执行的。我知道它有问题，因为它返回＆＃34; undefined＆＃34;。

问题：我做错了什么？

IndexQ3文件：

  <body>
      <script>
          function saveResponse() {return document.getElementById('text').value;}
          function returnText () {return "New Text!"} //function that changes the xx element
          //function returnSrc () {var aaaa = '"' + returnCellValue(6) + '"'} //this approach is not working

          function xxx() //function that is run when user clics button Next Question
          {
            document.getElementById("xx").innerHTML = returnText(); //Works

            //SPOT 1 
            //the next line of code works partly - the myFunc_3() does get and write the value correctly
            //but the variable uu is undefined despite "return b"
            var uu = google.script.run.myFunc_3(); //
            if(typeof uu == typeof "asdf") {uu = "1"} else {uu = "2"} //src value will be changed to 2 because of undefined

            //document.getElementById("img").src = "https://www.google.com/images/srpr/logo3w.png"
            document.getElementById("img").src = uu; //the scr value comes out as undefined

丹尼尔，谢谢！

如果其他人正在努力解决这个问题，那就是我所做的。在函数xxx（）中，我添加了google.script.run.withSuccessHandler(onSuccess).myFunc_3()。然后在body script标签中添加。

function onSuccess(sss) {
             var uu = sss;
             document.getElementById("img").src = sss;   
           }

无法更改image.src属性+函数执行但不返回值
