将IMPORTXML转换为具有自动更新功能的Google Apps脚本 [英] IMPORTXML into a Google Apps Script with Automatic Update

问题描述

我正在尝试使Google表格应用程序脚本适用于我正在使用的IMPORTXML.

I'm trying to get a Google sheets apps script to work for an IMPORTXML I'm using.

A1
=importxml("http://www.nfl.com/liveupdate/scorestrip/ss.xml","//@q")

A2
=importxml("http://www.nfl.com/liveupdate/scorestrip/ss.xml","//@h")

数据从 A1:B16

根据我在网上找到的脚本进行自动刷新:

According to a script I found on web to have it auto refresh:

function getData() {
  var queryString = Math.random();

  var cellFunction1 = '=IMPORTXML("' + SpreadsheetApp.getActiveSheet().getRange('A1').getValue() + '?' + queryString + '","'+ SpreadsheetApp.getActiveSheet().getRange('A2').getValue() + '")';
  SpreadsheetApp.getActiveSheet().getRange('C1').setValue(cellFunction1);

  var cellFunction2 = '=IMPORTXML("' + SpreadsheetApp.getActiveSheet().getRange('A4').getValue() + '?' + queryString + '","'+ SpreadsheetApp.getActiveSheet().getRange('A5').getValue() + '")';
  SpreadsheetApp.getActiveSheet().getRange('C2').setValue(cellFunction2);
}

我不知道我该在我的代码中放置/替换什么.如果有人可以帮助我解释要进行更改以使其在我的工作表中起作用/提供一些示例，那将是巨大的帮助.

I don't know what I'm supposed to be putting/replacing in that code with mine. If someone could help me to explain what I'm supposed to be changing to get it to work in my sheet/provide some examples of how one might look that would be a huge help.

我感激

推荐答案

您可以使用 SO帖子的代码段:

You can update the function by using getFormula() then setFormula() in a time-driven trigger function. Here is a code snippet from a related SO post:

/**
 * Go through all sheets in a spreadsheet, identify and remove all spreadsheet
 * import functions, then replace them a while later. This causes a "refresh"
 * of the "import" functions. For periodic refresh of these formulas, set this
 * function up as a time-based trigger.
 *
 * Caution: Formula changes made to the spreadsheet by other scripts or users
 * during the refresh period COULD BE OVERWRITTEN.
 *
 * From: https://stackoverflow.com/a/33875957/1677912

function RefreshImports() {
  var lock = LockService.getScriptLock();
  if (!lock.tryLock(5000)) return;             // Wait up to 5s for previous refresh to end.
  // At this point, we are holding the lock.

  var id = "YOUR-SHEET-ID";
  var ss = SpreadsheetApp.openById(id);
  var sheets = ss.getSheets();

  for (var sheetNum=0; sheetNum<sheets.length; sheetNum++) {
    var sheet = sheets[sheetNum];
    var dataRange = sheet.getDataRange();
    var formulas = dataRange.getFormulas();
    var tempFormulas = [];
    for (var row=0; row<formulas.length; row++) {
      for (col=0; col<formulas[0].length; col++) {
        // Blank all formulas containing any "import" function
        // See https://regex101.com/r/bE7fJ6/2
        var re = /.*[^a-z0-9]import(?:xml|data|feed|html|range)\(.*/gi;
        if (formulas[row][col].search(re) !== -1 ) {
          tempFormulas.push({row:row+1,
                             col:col+1,
                             formula:formulas[row][col]});
          sheet.getRange(row+1, col+1).setFormula("");
        }
      }
    }

    // After a pause, replace the import functions
    Utilities.sleep(5000);
    for (var i=0; i<tempFormulas.length; i++) {
      var cell = tempFormulas[i];
      sheet.getRange( cell.row, cell.col ).setFormula(cell.formula)
    }

    // Done refresh; release the lock.
    lock.releaseLock();
  }
}

希望这会有所帮助.
