我必須檢查天氣某個屬性是否存在,然後才能運行Google電子表格附加菜單中列出的功能。我不想爲每個函數創建相同檢查的副本,而是希望創建一個可以將該函數作爲參數運行的單個函數。我怎樣才能做到這一點?我怎樣才能傳遞一個函數來運行一個函數?
下面是我的非功能測試代碼,但您可能會明白。
function testRun(){
//in practicality this would be an add-on menu
test1Check('test1()');
}
function test1(){
Logger.log("Function Ran");
}
function test1Check(functionToRun){
var labels = PropertiesService.getDocumentProperties().getProperty('labels');
var ui = SpreadsheetApp.getUi(); // Same variations.
if (!labels) {
var result = ui.alert(
'You have not yet set up the page for gClassFolders',
'Would you like to do this now?',
ui.ButtonSet.YES_NO);
// Process the user's response.
if (result == ui.Button.YES) {
// User clicked "Yes".
setupGCF();
}
}
else {
functionToRun;
}
}
