Google Apps Script : Making an A Function Execute on Open - google-apps-script

Question

I found a script that will move my spreadsheet to a folder. How can I make it so that the functions runs when the spreadsheet is open. I will be applying this to a template so that everytime the template is opened, the "Copy of " spreadsheet file will automatically be moved to my Packing Lists folder.
Here's the code I have....
function MoveFileTo()
{
var docs=DocsList.find('Save Test');
var doc=docs[0]; /*Since we assume there is only one file with the name "Hello World", we take the index 0 */
var folders = doc.getParents();
var newFolder=DocsList.getFolder('Packing Lists');
doc.addToFolder(newFolder); // This will add the document to its new location.
var docParentFolder=folders[0];
doc.removeFromFolder(docParentFolder); // This will remove the document from its original location.
}
EDIT: I tried changing function MoveFileTo to onOpen() and onEdit() but it doesn't seem to work properly. Is there something I am missing?

Try use driveapp instead of doclist (it's deprecated). the impinball comment is really usefull, you should have a look at it.
Anyway here a working code:
function myFunction() {
var destFolder = DriveApp.getFolderById("FOLDER_ID_WHERE8YOU_WANT_TO_MOVE_YOUR_FILES");
var fileList = DriveApp.searchFiles("mimeType = 'application/vnd.google-apps.spreadsheet' and title contains 'FILE_TITLE'"); // change this search if necessary
var originalFileId="THE_ID_OF_THE_ACTUAL_SPREADSHEET_TO_BE_EXCLUDED_FROM_THE_SCRIPT_TREATMENT";
while(fileList.hasNext()){
var fileToMove = fileList.next();
if(fileToMove.getId()==originalFileId){
continue; // don't do anything if it's the original file
}
var papas = fileToMove.getParents();
destFolder.addFile(fileToMove); // do the job
while(papas.hasNext()){
papas.next().removeFile(fileToMove); // remove the actuals parents (can be more than one)
}
}
}
