I created a Google Apps Script add-on to display a sidebar on click:
function displayPage_() {
getScriptProperties_()
var htmlTemplate = HtmlService.createTemplateFromFile('PAGE');
var html = htmlTemplate.evaluate()
.setTitle('Connector');
SpreadsheetApp.getUi().showSidebar(html);
}
This successfully loads the file PAGE.html as long as it is simple html. However, when I try to add include like this:
<!DOCTYPE html>
<html>
<head>
<base target="_top">
<?!= include("STYLESHEET"); ?>
</head>
<body>
</body>
</html>
It throws this error:
[17-02-09 08:55:50:239 MST] Execution failed: ReferenceError: "include" is not defined.
It doesn't matter what is in the include it always fails.
I have done this before and it worked. As far as I can tell, I have this set up just like the other project, but it doesn't work in this project. I assume that I forgot to enable something, but don't know how to tell what is missing because the transcript is vague.
What am I missing? Or, doing wrong?
I got crazy too... Found it in an example provided in Google Script Reference, what I didn't know was that include() is a user-defined function. Paste this code and it will work:
function include(File) {
return HtmlService.createHtmlOutputFromFile(File).getContent();
};
Let me know if I understood properly.
