更新列表框选择的索引

Question

我有一个谷歌脚本，可以在谷歌电子表格和谷歌表格之间进行读写。它基本上是访问材料数据库的一种形式。

首次访问表单时，它会显示所有空白字段，填充材料ID（CW_ID）的“选择器”列表框以及选择器列表框中“新建”部分的选项。如果用户保持“新建”状态，则字段保持空白，以便用户手动填充它们并将其作为数据库中的新项目附加。如果用户滚动“选择器”列表框并选择CW_ID，它将从电子表格中提取并使用与所选CW_ID对应的数据填充字段，供用户进行编辑（修改部件的详细信息）。

因为我在数据库中使用SQL结构，所以我有几个链接表：

• 材料表（包含有关零件的大部分信息，包括制造商[制造商_ID]的ID）

• 制造商表（链接到materials.manufacturer_ID）

目前，表单仅使用材料表填充字段，因此在“制造商”字段中，它仅显示ID号。出于用户目的，我希望脚本检查材料表中显示的manufacturer_ID，进入制造商表，查找匹配项并让制造商列表框将其显示为当前选定的索引。 （或者只是让制造商的名字出现在现场）

到目前为止，这是我脚本的一部分：

  //Next, i create the save button and assign the function "saved" to be activated whenever the button is pressed.
  var saveButton = projectApp.createButton('Save');
  var saveHandler = projectApp.createServerHandler('saved');
  saveHandler.addCallbackElement(panel);
  saveButton.addClickHandler(saveHandler);

  //Now that all the componentes of the form have been declared and set up, I'm going to assemble them on the panel.
  panel.setSpacing(6);
  panel.add(nameLabel);
  panel.add(nameField);
  panel.add(gmailLabel);
  panel.add(gmailField);  
  panel.add(selectorLabel);
  panel.add(selector);
  panel.add(descriptionLabel);
  panel.add(descriptionField);
  panel.add(manufSelectorLabel);
  panel.add(manufSelector);

  panel.add(manufacturerField);
  panel.add(modelnumberLabel);
  panel.add(modelnumberField);
  panel.add(saveButton);
  panel.add(savedLabel);
  projectApp.add(panel);
  return projectApp;
}


  //This function looks to see what has been selected in the drop down menu, and then pulls the appropriate data from the spreadsheet to display in the fields.
   function goSelection(e){
  var activeEmail = Session.getActiveUser().getEmail();
  var app = UiApp.getActiveApplication();
  var gmailField = app.getElementById('gmailArea');
  var nameField = app.getElementById('nameArea');
  var chosen = e.parameter.selectionBox;
  var ss = SpreadsheetApp.openByUrl("https://docs.google.com/something")

  var materialsSheet = ss.getSheetByName('materials');
  var manufacturersSheet = ss.getSheetByName('manufacturers');
  var vendorsSheet = ss.getSheetByName('vendors');
  var materialsData = materialsSheet.getDataRange().getValues();
  var manufacturersData = manufacturersSheet.getDataRange().getValues();
  var vendorsData = vendorsSheet.getDataRange().getValues();

  var panel = app.getElementById('face');
  var standardpartField = app.getElementById('standardpartArea');
  var descriptionField = app.getElementById('descriptionArea');
  var manufacturerField = app.getElementById('manufacturerArea');
  var manufacturerListField = app.getElementById('manufSelectionBox');
  var modelnumberField = app.getElementById('modelnumberArea');

if (chosen != 'New') {
 for (var i=1; i < materialsData.length; i++){
    if (materialsData [i][1] == "Email"){
  //if row in Column B does not equal gmail, skip to i++
  continue;
   }
   if (materialsData [i][2] != chosen){
    continue;
    }
    nameField.setText(materialsData [i][0]);
    gmailField.setText(materialsData [i][1]);
    standardpartField.setText(materialsData [i][3]);
    descriptionField.setText(materialsData [i][4]);


    //****THIS IS THE PART I'M WORKING ON
    //set manufacturerField to manufacturer of current row
    //loop through manufacturer sheet until row matches with manufacturersField
    //when a match is found, selector box index to same row

    manufacturerField.setText(materialsData [i][5]);      

    for (var i=1; i < manufacturersData.length; i++){
      if (manufacturersData [i][1] == "Email"){
      //if row in Column B does not equal Email, skip to i++
        continue;
      }
      if (manufacturersData [i][2] != manufacturerField){
        continue;
      }
     manufacturerListField.setSelectedIndex(i);
    }

    modelnumberField.setText(materialsData [i][6]);
    }
}

这对我有意义，但它不起作用。我点击选择器列表框中的一个部分，所有信息都填充到字段中，正如我想要的那样。但是，制造商列表框不会跳转到正确的制造商（如制造商字段中所填充的那样），它只是坐在那里并按原样保留。

（见图片以了解表格的外观）

制造商列表框和字段显示，但是现在，只有制造商字段更改才能在选择部件时显示数据。

任何帮助都会非常感激！ ：）

以下是一些可以帮助您开始使用HTML服务的HTML：

输入表格HTML

<div>
  <div>
      Name:
     <select>
      <option value="one">One</option>
      <option value="two">Two</option>

      <option value="four">Four</option>
    </select>
  </div>

设计你的HTML。然后在Apps脚本项目中创建一个HTML文件。

您的doGet()应该只有提供HTML的代码。

Code.gs

function doGet() {

  return HtmlService.createTemplateFromFile('myHTML_File_Name_Here')
    .evaluate() // evaluate MUST come before setting the NATIVE mode
    .setTitle('Materials Form')
    .setSandboxMode(HtmlService.SandboxMode.NATIVE);
};

创建另一个.gs文件来处理数据。这就是用于将数据写入电子表格的所有代码都将用于的地方。

如果您需要填充选择框，可以在HTML的脚本标记中使用JavaScript。

通过我给你的，你应该能够创建一个独立的应用程序脚本HTML服务应用程序。发布它，然后运行它。你可能用你当前的项目做到了。
