目标是通过大约10,000行链接。确定哪些页码> 3并突出显示第一列。我完成了所有这些,但问题是它需要Url Fetch太长时间,我遇到最大运行时错误。无论如何我可以加速这段代码,这样我可以通过10000行吗?
function readColumns() {
//program is going to run through column 3 by going through the amount of rows, truncating last three characters to see if pdf, then highlighting first column
var sheet = SpreadsheetApp.getActiveSheet();
var columns = sheet.getDataRange();
var rowNum = columns.getNumRows();
var values = columns.getValues();
var html;
var htmlString;
for(var i = 1; i <= rowNum; i++){
var columnLogger = values[i][2];
try{
html = UrlFetchApp.fetch(values[i][2],
{
muteHttpExceptions: true,
}
);
}catch(e){
Logger.log("Error at line " + i);
var error = true;
}
htmlString = html.getContentText();
var index = htmlString.indexOf("Pages") + 6;
var pageNumber = parseInt(htmlString.charAt(index),10);
var lastChars = "" + columnLogger.charAt(columnLogger.length-3) + columnLogger.charAt(columnLogger.length-2) + columnLogger.charAt(columnLogger.length-1);
if((error) || (!lastChars.equals("pdf") && values[i][6].equals("") && !pageNumber >= 3)){
//goes back to first column and highlights yellow
var cellRange = sheet.getRange(1, 1, rowNum, 3)
var cell = cellRange.getCell(i+1, 1)
cell.setBackground("yellow");
}
}
}
编辑 - 短脚本:
function foreverCall(){
var start = 1480;
for(;;){
readColumns(start);
start = start + 100;
}
}
function readColumns(start) {
//program is going to run through column 3 by going through the amount of rows, truncating last three characters to see if pdf, then highlighting first column
var sheet = SpreadsheetApp.getActiveSheet();
var columns = sheet.getDataRange();
var rowNum = columns.getNumRows();
var values = columns.getValues();
var html;
var htmlString;
var error;
for(var i = start; i < start+100; i++){
if(loop(values, error, html, htmlString, rowNum, sheet, columns, i)){
var cellRange = sheet.getRange(1, 1, rowNum, 3)
var cell = cellRange.getCell(i, 1)
cell.setBackground("yellow");
}
}
}
function loop(values, error, html, htmlString, rowNum, sheet, columns, i){
var columnLogger = values[i][2];
var lastChars = columnLogger.slice(-4);
if(!lastChars.equals(".pdf") && values[i][6].equals("")){
return true;
}else{
try{
error = false
html = UrlFetchApp.fetch(values[i][2].toString());
if(html == null){
error = true;
}
}catch(e){
Logger.log("Error at line " + i);
error = true;
}
if(!error){
htmlString = html.getContentText();
var index = htmlString.indexOf("Pages") + 6;
var pageNumber = parseInt(htmlString.charAt(index),10);
}
//goes back to first column and highlights yellow
if(error || !pageNumber >= 3){
return true;
}
}
return false;
}
答案 0 :(得分:2)
您可以替换它:
var lastChars = "" + columnLogger.charAt(columnLogger.length-3) + columnLogger.charAt(columnLogger.length-2) + columnLogger.charAt(columnLogger.length-1);
有了这个:
var lastChars = columnLogger.slice(-3);
您还可以从html侧边栏或对话框启动fetch脚本以运行短批处理,然后返回到成功处理程序,然后根据返回值启动另一个批处理。返回值也可用于在下一行开始下一批。它实际上需要更长的时间才能运行,但是你可以通过保持批量很小来保持在脚本限制之下。

您可以使用
替换该行var lastChars = columnLogger.slice(-3);
