我收到的名为:names的变量未定义 任何有关它为什么不显示结果的帮助。在按下搜索后,它将显示在记录器中,但不会显示在index.html或Web侧。
代码:
// var names =[]; //I tried using a global variable but with no luck
function SearchFiles(searchTerm) {
var searchFor = "title contains '" + searchTerm + "'";
var owneris = "and 'Email@email.com' in Owners";
var names = [];
var fileIds = [];
Logger.log(searchFor + " " + owneris);
var files = DriveApp.searchFiles(searchFor + " " + owneris);
while (files.hasNext()) {
var file = files.next();
var fileId = file.getId(); // To get FileId of the file
fileIds.push(fileId);
var name = file.getName();
names.push(name);
}
for (var i = 0; i < names.length; i++) {
//this is showing in the Logger
Logger.log(names[i]);
Logger.log("https://drive.google.com/uc?export=download&id=" + fileIds[i]);
}
}
function returnNames(names) {
return '<h3><b>returnNames has ran.!</b></h3> <br>' + names; // Why does this names variable return undefined???
}
function doGet(e) {
var template = HtmlService.createTemplateFromFile('Index');
return template.evaluate()
.setTitle('Search Drive')
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
}
function processForm(searchTerm) {
var resultToReturn;
Logger.log('processForm was called! ' + searchTerm);
resultToReturn = SearchFiles(searchTerm);
Logger.log('resultToReturn: ' + resultToReturn)
// shows as undefined in the logger
return resultToReturn;
}

我认为你是以错误的方式做的。如果您在returnNames(names)
结束时返回SearchFiles
,并且只需在google.script.run.withSuccessHandler(handleResults).processForm(searchTerm);
内拨打index.html
,就会有效:

function SearchFiles(searchTerm) {
var searchFor = "title contains '" + searchTerm + "'";
var owneris = "and 'Email@email.com' in Owners";
var names = [];
var fileIds = [];
Logger.log(searchFor + " " + owneris);
//Logger.log(searchFor);
var files = DriveApp.searchFiles(searchFor + " " + owneris);
//var files = DriveApp.searchFiles(searchFor);
while (files.hasNext()) {
var file = files.next();
var fileId = file.getId(); // To get FileId of the file
fileIds.push(fileId);
var name = file.getName();
names.push(name);
}
for (var i = 0; i < names.length; i++) {
//this is showing in the Logger
Logger.log(names[i]);
Logger.log("https://drive.google.com/uc?export=download&id=" + fileIds[i]);
}
return returnNames(names); // Here call directly returnNames and get the wanted result
}
function returnNames(names) {
var result = '<h3><b>returnNames has ran.!</b></h3> <br>'; // + names; // Why does this names variable return undefined???
result += '<div>names.length = '+names.length+'</div>';
for(var i=0; i<names.length; i++) {
result += '<div>'+names[i]+'</div>';
}
return result;
}
function doGet(e) {
var template = HtmlService.createTemplateFromFile('Index');
return template.evaluate()
.setTitle('Search Drive')
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
}
function processForm(searchTerm) {
var resultToReturn;
Logger.log('processForm was called! ' + searchTerm);
resultToReturn = SearchFiles(searchTerm);
Logger.log('resultToReturn: ' + resultToReturn)
// shows as undefined in the logger
return resultToReturn;

使用术语"test"

您可以通过这种方式尝试将名称传递给Google脚本。
在SearchFiles(searchTerm)中,您返回名称(可以是空白数组或带有名称的值数组)。
<!DOCTYPE html>
<html>
<head>
<base target="_top">
<script>
function displayMessage() {
var searchTerm;
searchTerm = "DUMMY TEXT";//document.getElementById('idSrchTerm').value;
console.log('searchTerm: ' + searchTerm);
//google.script.run.processForm(searchTerm);
//google.script.run
//.withSuccessHandler(handleResults)
//.returnNames(google.script.run.processForm(searchTerm));
processForm(searchTerm);
}
function handleResults(searchTerm) {
console.log('Handle Results was called! ');
document.writeln(searchTerm);
}
</script>
</head>
<body>
<input type="text" id="idSrchTerm" name="search">
<input type="button" value="submitButton" name="submitButton" onclick="displayMessage()" />
</body>
</html>
