將Google試算表當作簡易資料庫,利用Google apps cript 在網頁上操作查詢

若我有一試算表資料

縣市	status	aqi
新北市	普通	62
臺北市	普通	66
桃園市	普通	61
臺中市	良好	44
臺南市	普通	56
高雄市	普通	77
宜蘭縣	普通	74

要如何在web上操作查詢, 要分成前後端來看

後端是google apps script

function doGet(e) {

  let params = e.parameters;  
  let url = ScriptApp.getService().getUrl();
//  return HtmlService.createHtmlOutput(url);
  
  return HtmlService.createTemplateFromFile('index')
  .evaluate();
 
}



function getMsg() {
  return 'Hello,world';
}

function getItems(name){
  Logger.log("query name:"+name);
  let url = 'https://docs.google.com/spreadsheets/d/14bY56g1SuMleCfY-67pBkfJi0j7exj04aLvOYopSEj0/edit?usp=sharing';
  let SpreadSheet = SpreadsheetApp.openByUrl(url);
  let sheet = SpreadSheet.getSheets()[0];
  let lastRow = sheet.getLastRow();
  let items = [];
  
  //init get all items
  
  if(name === "init"){
    for(let i=2; i<lastRow+1; i++){    
      let item = {};
     
      item.name = sheet.getSheetValues(i, 1,1,1)[0][0];
      item.status = sheet.getSheetValues(i, 2,1,1)[0][0];
      item.aqi = sheet.getSheetValues(i, 3,1,1)[0][0];
      items.push(item);   
    }
  } else {
    for(let i=2; i<lastRow+1; i++){    
      let item = {};
      item.name = sheet.getSheetValues(i, 1,1,1)[0][0];
      item.status = sheet.getSheetValues(i, 2,1,1)[0][0];
      item.aqi = sheet.getSheetValues(i, 3,1,1)[0][0];  
      if(name === item.name){
        items.push(item);  
      }
       
    }
  } 
  

//  Logger.log(items);
  return items;
}

doGet() 是處理 http get的方式

getItems()則是讀取試算表的資料

為了要方便操作DOM, 我使用了vue.js, 最主要的語法在callback 這一段

google.script.run.withSuccessHandler(onCreatedItems).getItems("init");
