I created an array in a separate GS file using the code provided below. I tried calling it in my HTML file. My goal is to compare the contents the array to the parameter email
. However, the value returned by google.script.run.withSuccessHandler()
is undefined
//in GS
function mailGetter()
{
//open sheet
var sheet = SpreadsheetApp.openByUrl("https://sheet.url").getSheetByName("Email Sheet").activate();
//get size of given row range
var row_data_email = sheet.getRange("C2:C").getValues();
var emailArray = row_data_email.join().split(',').filter(Boolean);
Logger.log(emailArray);
return emailArray;
}
//in HTML
function checkEmail(email)
{
var reg1 = /^[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}$/;
var arraySize = google.script.run.withSuccessHandler(misc).sizeGetter();
console.log(arraySize);
var emailArray = new Array(arraySize);
emailArray = google.script.run.withSuccessHandler(misc).mailGetter();
console.log(emailArray);
if (reg1.test(email) == false)
{
emails.style.border = "1px solid red";
document.getElementById('submitBtn').disabled = true;
}
else if (reg1.test(email) == true)
{
emails.style.border = "1px solid green";
document.getElementById('submitBtn').disabled = false;
}
for (var row = 0; row < arraySize; row++)
{
if (emailArray[row][0] == email)
{
emails.style.border = "1px solid green";
document.getElementById('submitBtn').disabled = false;
break;
}
else if (emailArray[row][0] != email)
{
emails.style.border = "1px solid red";
document.getElementById('submitBtn').disabled = true;
}
}
}
function misc()
{
console.log("Pass");
}
google.script.run
) return value, which will always be undefined
./*Create a promise around old callback api*/
const p = func =>
new Promise(resolve=>
google.script.run.withSuccessHandler(resolve)[func]()
);
async function checkEmail(email) //modified
{
var arraySize = await p('sizeGetter');//Wait to resolve
console.log(arraySize);
//var emailArray = new Array(arraySize);
var emailArray = await p('mailGetter');//Wait to resolve
console.log(emailArray);
//....
}
Getter
s to a single server function, it'll be better.async
/await
. But if you wait for each response from the server as shown above, your front end/UI will be slow. Wait only if absolutely necessary. Calls to server should be non-blocking/asynchronous.If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
