获取文本输入框的值,而无需在Google Apps脚本中使用document.getElementById?

如何解决获取文本输入框的值,而无需在Google Apps脚本中使用document.getElementById?

我正在创建一个工具,该工具使用google apps脚本html服务创建一个页面,该页面将为所选主题创建一个新的google doc,并使用文本输入框中的值(如果已编辑)以及默认值对于选定的主题,如果没有,但是我不能使用document.getElementById(),并且我想知道是否还有其他选择。我的代码在下面。

function doGet() {
  return HtmlService.createHtmlOutputFromFile('Index.html');
}

function customDoc(subject) {

  var formattedDate = Utilities.formatDate(new Date(),Session.getScriptTimeZone(),'M/d/yyyy');
 var la=['teacher@example.com','LA for '+ formattedDate]
  var math=['teacher@example.com','math for '+ formattedDate]
 var spanish=['teacher@example.com','Espanol para ' +formattedDate]
var science = ['teacher@example.com','science for '+formattedDate]
var is = ['teacher@example.com','I&S for '+formattedDate]
var cycle= [la,science,is,spanish,math]
var e = null  
var d = null
var s = null
var m = null
if (Document.getElementById('Email') === ' '){
  e=cycle[subject][1]   }
 
  else {e=Document.getElementById('Email')}

  if (Document.getElementById('docName') === ' '){
  d=cycle[subject][2]   }
 
  else {d=Document.getElementById('docName')}

  if (Document.getElementById('Sub') === ' '){
  s=cycle[subject][2]   }
 
  else {s=Document.getElementById('Sub')}

 if (Document.getElementById('message') === ' '){
   m = ' '}
  else {m=Document.getElementById('message')}

var doc = DocumentApp.create(d)
var doccu = doc.getUrl();
var body = m + '    ' + doccu
   GmailApp.sendEmail(e,s,body)
console.log(e);
  console.log(s);
  console.log(body);
  console.log(doccu);
  console.log(d);
}
<!DOCTYPE html>
<html>
  <body>
    <h1>CREATE DOC</h1>
    <p>Email</p>
    <input type="text" id="Email" value=" " style="border-radius: 20px; border-color: crimson; border-width: 20px" />
    
    <p style="font-family: Times New Roman,Times,serif">Doc name</p>

    <h2>Fill blanks for subject:</h2>

    <button id="1" onclick="google.script.run.customDoc(this.id)">LA</button>
    <button id="2" onclick="google.script.run.customDoc(this.id)">Science</button>
    <button id="3" onclick="google.script.run.customDoc(this.id)">Individuals and societies</button>
    <button id="4" onclick="google.script.run.customDoc(this.id)">Spanish</button>
    <button id="5" onclick="google.script.run.customDoc(this.id)">math</button>
  </body>
</html>

解决方法

document.getElementById()是一种客户端功能,因此它必须位于您的HTML中。 (请记住,customDoc()是服务器端函数。)

您可以调用document.getElementById('docName')来获取文档名称文本框,然后访问其value属性来获取文本框内的文本。然后,您可以将此值以及主题名称传递给customDoc()

采用相同的方法从HTML输入中获取其他文本框值。

在我对您的原始问题的response中,为了清楚起见,我决定重复onclick="google.script.run.customDoc(this.id)"。现在,在调用customDoc()之前还需要执行其他步骤,因此最好调用中间函数。您可以为所有按钮添加event listener,而不是为每个按钮指定onclick。因此,只要单击按钮,就会调用中介getValuesAndCreateDoc()函数。

<!DOCTYPE html>
<html>
  <style>
    input {
      border-radius: 20px;
      border-color: crimson;
      border-width: 20px;
    }
  </style>
  <body>
    <h1>CREATE DOC</h1>
    <p>Email</p>
    <input type="text" id="Email">
    
    <p style="font-family: Times New Roman,Times,serif">Doc name</p>
    <input type="text"  id="docName">
    
    <p>Subject</p>
    <input type="text" id="Sub">
    
    <p>message</p>
    <input type="text" id="message">

    <h2>Fill blanks for subject:</h2>

    <button id="la">LA</button>
    <button id="science">Science</button>
    <button id="is">Individuals and societies</button>
    <button id="spanish">Spanish</button>
    <button id="math">math</button>
    
    <script>
      // Run getValuesAndCreateDoc() when a button is clicked
      const buttons = document.getElementsByTagName('button');
      for (let i = 0; i < buttons.length; i++) {
        buttons[i].addEventListener('click',getValuesAndCreateDoc);
      }
      
      /**
       * Get the user values and create the document.
       * @param {Event} event
       */
      function getValuesAndCreateDoc(event) {
        const clicked = event.target.id;
        const email = document.getElementById('Email').value.trim();
        const docName = document.getElementById('docName').value.trim();
        const sub = document.getElementById('Sub').value.trim();
        const message = document.getElementById('message').value.trim();
        console.log('Clicked: ' + clicked);
        console.log('Email: ' + email);
