我如何制作迭代上传文件？ [英] How can I make an iterated upload files?

问题描述

我有一个google apps脚本来上传文件：

 函数doGet（）{
 ... 
选择代码文件
 ... 
返回应用程序; 
} 
 
 doPost函数（e）{
 ... 
代码将文件添加到文件夹
 ... 
返回应用程序; 
} 
  

我想重复n次文件上传。我能怎么做？

  //从此处找到的脚本修改http://www.googleappsscript.org/miscellaneous/creating-form-elements-dynamically-using-google-apps-script-gas 
 
函数doGet（）{
 var app = UiApp.createApplication（）; 
 var panel = app.createVerticalPanel（）; 
 var formPanel = app.createFormPanel（）; 
 var instructionsLabel = app.createLabel（'把你的指示放在这里'）; 
 var filesLabel = app.createLabel（'Add Files to Upload'）; 
 var table = app.createFlexTable（）。setId（'table'）。setTag（'0'）; //这里标签会计算文件的数量
 //为表格写入标题
 var header = app.createLabel（'File（s）'）; 
 table.setWidget（0，0，header）; 
 
 //添加第一行文件
 addFirstRow（app）; 
 var hidden = app.createHidden（）。setId（'hiddenRowHolder'）。setName（'hidden'）。setValue（table.getTag（））; 
 //添加一个按钮提交信息
 var button = app.createSubmitButton（'Upload File（s）'）; 
 panel.add（instructionsLabel）.add（filesLabel）.add（table）.add（hidden）.add（button）; 
 formPanel.add（panel）; 
 app.add（formPanel）; 
返回应用程序; 
} 
 
函数addFirstRow（app）{
 var table = app.getElementById（'table'）; 
 var tag = parseInt（table.getTag（））; 
 Logger.log（tag）; 
 var numRows = tag + 1; 
 if（numRows> 1）{
 table.removeCell（numRows-1,5）; 
 table.removeCell（numRows-1，4）; 
} 
 Logger.log（numRows）; 
 var uploadWidget = app.createFileUpload（）; 
 var uploadWidgetName = uploadWidget.setName（'file'+ numRows）; 
 var uploadWidgetId = uploadWidget.setId（'file'+ numRows）;

} 
 
函数addButtons（app）{
 var table = app.getElementById（'table'）; 
 var numRows = parseInt（table.getTag（））; 
 
 
 //创建处理程序以添加/删除行
 var addRemoveRowHandler = app.createServerHandler（'addRemoveRow'）;

 //添加行按钮和处理程序
 var addRowBtn = app.createButton（'+'）.setId（'addOne'）。setTitle（'Add row'）; 
 table.setWidget（numRows，4，addRowBtn）;

 //将标签减一个
 var numRows =标签-1;

 //设置表格的新标签
 table.setTag（numRows）; 
 hidden.setValue（numRows）; 
 //在前一行添加按钮

} 
返回应用; 
} 
 
函数doPost（e）{

 Logger.log（numFiles）; 
 for（var i = 1; i <= numFiles; i ++）{
 var fileBlob = e.parameter ['file'+ i]; 
 var newFile = DocsList.getFolderById（Your File Id Goes Here）。createFile（fileBlob）; //用文件夹ID替换字符串，您要放置文件
} 
 var app = UiApp.getActiveApplication（）; 
 var label = app.createLabel（已成功上传numFiles +'文件'）; 
 app.add（label）; 
返回应用程序; 
} 
  

I have a google apps script to upload files:

function doGet () {
... 
select code file 
... 
return app; 
} 

doPost function (e) {
... 
code add file to folder 
...
return app; 
} 

I want to repeat n times the file uploads. How can I do? thanks

解决方案

With some help from Serge, I was able to finish what I started on this.

//modified from script found here http://www.googleappsscript.org/miscellaneous/creating-form-elements-dynamically-using-google-apps-script-gas

function doGet() {
  var app = UiApp.createApplication();
  var panel = app.createVerticalPanel();
  var formPanel = app.createFormPanel();
  var instructionsLabel = app.createLabel('Put your instructions here');
  var filesLabel = app.createLabel('Add Files to Upload');
  var table = app.createFlexTable().setId('table').setTag('0'); //Here tag will count the number of files
  //Write the header for the table
  var header = app.createLabel('File(s)');
  table.setWidget(0, 0, header);

  //Add the first row of files
  addFirstRow(app);
  var hidden = app.createHidden().setId('hiddenRowHolder').setName('hidden').setValue(table.getTag());
  //Add a button to submit the info
  var button = app.createSubmitButton('Upload File(s)');
  panel.add(instructionsLabel).add(filesLabel).add(table).add(hidden).add(button);
  formPanel.add(panel);
  app.add(formPanel);
  return app;
}

function addFirstRow(app){
  var table = app.getElementById('table');
  var tag = parseInt(table.getTag());
  Logger.log(tag);
  var numRows = tag+1;
  if(numRows >1){
    table.removeCell(numRows-1, 5);
    table.removeCell(numRows-1, 4);
  }
  Logger.log(numRows);
  var uploadWidget = app.createFileUpload();
  var uploadWidgetName = uploadWidget.setName('file'+numRows);
  var uploadWidgetId = uploadWidget.setId('file'+numRows);
  table.setWidget(numRows, 0, uploadWidget);
  table.setTag(numRows.toString());
  addButtons(app);
}

function addButtons(app){
  var table = app.getElementById('table');
  var numRows = parseInt(table.getTag());


  //Create handler to add/remove row
  var addRemoveRowHandler = app.createServerHandler('addRemoveRow');
  addRemoveRowHandler.addCallbackElement(table);

  //Add row button and handler
  var addRowBtn = app.createButton('+').setId('addOne').setTitle('Add row');
  table.setWidget(numRows, 4, addRowBtn);
  addRowBtn.addMouseUpHandler(addRemoveRowHandler);

  //remove row button and handler
  var removeRowBtn = app.createButton('-').setId('removeOne').setTitle('Remove row');
  table.setWidget(numRows, 5, removeRowBtn);
  removeRowBtn.addMouseUpHandler(addRemoveRowHandler);
}

function addRemoveRow(e){
  Logger.log(e.parameter.source);
  var app = UiApp.getActiveApplication();
  var table = app.getElementById('table');
  var tag = parseInt(e.parameter.table_tag);
  var hidden = app.getElementById('hiddenRowHolder');
  var source = e.parameter.source;
  //Logger.log(tag);
  if(source == 'addOne'){
    table.setTag(tag.toString());
    hidden.setValue(tag+1);
    addFirstRow(app);
  }
  else if(source == 'removeOne'){
    if(tag > 1){
      //decrement the tag by one
      var numRows = tag-1;
      table.removeRow(tag);
      //Set the new tag of the table
      table.setTag(numRows);
      hidden.setValue(numRows);
      //Add buttons in previous row
      addButtons(app); 
    }
  }
  return app;
}

function doPost(e) {
  var numFiles = Number(e.parameter.hidden);
  Logger.log(numFiles);
  for (var i = 1; i<=numFiles; i++){
    var fileBlob = e.parameter['file'+i];
    var newFile = DocsList.getFolderById("Your File Id Goes Here").createFile(fileBlob);//replace string with folder id where you want to place your files
  }
  var app = UiApp.getActiveApplication();
  var label = app.createLabel(numFiles +' file(s) uploaded successfully');
  app.add(label);
  return app;
}
