I am writing an application that pulls task data (for a task management system) from rows in a Google Spreadsheet with conditions matching a query. I then send this data into a flexTable next to a checkbox with an onClickHandler as well as a textbox to enter in hours data. Below is the simplest example of how I have achieved this:
\\establish handler for checkboxes that are generated in flexTable
var updateHandler = app.createServerClickHandler('updateTasksfunc');
updateHandler.addCallbackElement(taskTable);
\\search Google Spreadsheet for rows matching condition
for(var i=1; i< taskData.length; i++){
if (taskData [i][1] !=employee){
continue;
}
\\look up if task is already completed, and set checkbox value to true/false
var complete = taskData[i][8].toString();
if(complete==="true"){var checkbox=true;}else{var checkbox=false;}
\\populate flexTable with values from spreadsheet query
taskTable.setWidget(i,0,app.createTextBox().setName('hours'+i).setWidth('50').setId("hour"+i)).setWidget(i,1,app.createCheckBox().setValue(checkbox).setName('complete'+i).addClickHandler(updateHandler)).setWidget(i,2,app.createLabel(taskData[i][2]).setWidth('250')).setWidget(i,3,app.createLabel(taskData[i][3]).setWidth('250')).setWidget(i,4,app.createLabel(taskData[i][4])).setWidget(i,5,app.createLabel(taskData[i][5])).setWidget(i,6,app.createLabel(taskData[i][6])).setWidget(i,7,app.createLabel(taskData[i][7])).setWidget(i,8,app.createTextBox().setVisible(false).setName("dataRow"+i).setValue(i))
}
\edits to doGet()
var numberOfItems = app.createTextBox().setName('rows').setValue(i).setVisible(false);
var rows1 = i+1;
taskTable.setWidget(rows1,0,numberOfItems)
I have stored the spreadsheet data row in the invisible textbox in column 8 of the flex table that I intend to use in the clickHandler function to update the Google Spreadsheet.
I have successfully activated a click handler that runs when a checkbox is clicked; however, I have not yet successfully figured out a way to grab data from the flexTable that I can use to update the Spreadsheet.
//Functional code below
function updateTasksfunc(e){
var app = UiApp.getActiveApplication();
var taskSS = SpreadsheetApp.openById('SPREADSHEETID');
var taskSH = taskSS.getSheets()[0];
var taskData = taskSS.getDataRange().getValues();
var results = [];// an array to collect results
var numberOfItems = e.parameter.rows;
app.add(app.createLabel(numberOfItems));
for(var n=0;n<numberOfItems;n++){
results.push([e.parameter['check'+n]]);// each element is an array of 2 values
}
for(var i=1;i<results.length;i++){
var check = results[i][0];
var row = i+1;
taskSH.getRange(row,9,1,1).setValue(check);
}
return app;
}
I am getting a generic error: cannot find function getRowCount() from generic.
I assume that this means that I am not properly calling my flexTable.
Any thoughts??
