Question

我刚接触Google Appscript和Javascript HTML。我正在开发一个使用google.script.run接收数组的web应用程序，它可以正常工作，但似乎只能访问接收函数中的变量。

我的问题是，有什么办法可以从Code.gs接收变量并将其设置为全局变量？ HTML：

<html>
  <head>
    <body>
      <div id="variables">
        <input id="state">State</input>
        <input id="equity-spread">Equity</input>
        <input id="age-spread">Age</input>
        <input id="distance">Distance</input>
      </div>
      <div id="letter">
        <button>a</button>
        <button>b</button>
        <button>c</button>
        <button>d</button>
        <button>e</button>
        <button>f</button>
        <button>g</button>
        <button>h</button>
        <button>i</button>
      </div>
      <div>
      </div>
    </body>
  </head>
</html>

index.js

function formClicked(){
  var state = document.getElementById("state").value
  var equity = document.getElementById("equity-spread").value
  var age = document.getElementById("age-spread").value
  var distance = document.getElementById("distance").value
  //this function is only to capture and send user input to the server-side Code.gs
   google.script.run.withSuccessHandler(displayAnalysis).analysis(state,equity,age,distance)
  }

  document.getElementById("letter").addEventListener("click", checkInput);

Code.gs

function analysis(STATE,EQUITY,AGE,DIST){
  //spreadsheet analysis code here  

  var results = [a,b,c,d]
  return results

index.js

function displayAnalysis(items){ 
  console.log(items) //this correctly displays the [a,b,c,d] array
  //additional code that modifies the array 
}

function checkInput(e){
  //I created this function because I need the event listener and I couldn't find a way to insert an event listener on the displayAnalysis()
  //I need to access the "items" variable here, but can't figure out how
  
var input = e.target.closest("button").innerHTML 
  console.log(input)
var result = items.indexOf(input) 
  //I can't do indexOf because "items" is undefined
  //I need to evaluate the selected value from the array that was sent over from Code.gs
  var original = items //this produces an undefined
}

基本上，我需要在var items和displayAnalysis()函数中都使用checkInput来评估从Code.gs发送的数组中是否找到了选定的值。

由于尝试读取可以公开“读取”变量的位置，因此我尝试设置设置var _data = items。我也将displayAnalyis函数重写为这样的全局变量：


var publicVar = function displayAnalysis(items)
//this also doesn't work

最后，我还尝试将事件监听器和“ items”变量放在相同的函数中，例如（这将是最佳解决方案）：

function formClicked(){
  var state = document.getElementById("state").value
  var equity = document.getElementById("equity-spread").value
  var age = document.getElementById("age-spread").value
  var distance = document.getElementById("distance").value
  google.script.run.withSuccessHandler(displayAnalysis).analysis(state,equity,age,distance)
  }

  document.getElementById("letter").addEventListener("click", displayAnalysis);

function displayAnalysis (e,items)
  //console returns "e" as undefined. The first parameter is always defined even if switched
  //this would be the ideal solution because I can receive the "items" and evaluate the "event(e)" together in the same function, but I can't get this to work either.

我觉得这是一个容易解决的问题，但我似乎无法找出我做错了什么。在这个问题上的任何帮助将不胜感激。
