Passing variable to HTML output and then into a scriptlet

Question

Code.gs

function doPost(e) {
    ...
    template.data += getCustomerData + "<br>";
}
return template.evaluate().setSandboxMode(HtmlService.SandboxMode.IFRAME);

index.html

...
<?= data ?>

The code shown does display the correct values. However, it doesn't translate <br> into HTML. I'm not sure why it isn't working since template.evaluate() is supposed to return an HtmlOutput object.

By default the strings are sanitized, converting special characters to their HTML encoded equivalents (such as < becoming <).

When outputting HTML you must use <?!= to avoid sanitizing the data.

<?!= data ?>

See the details on standard & force-printing scriptlets here: https://developers.google.com/apps-script/guides/html/templates#standard_scriptlets

This does set the data, however, it is limited in that the data needs to be formatted previously (unless its something simple like a string or number). For a more comprehensive way to pass a server variable to the client html, see this answer: I made an answer regarding this here: stackoverflow.com/a/38314034/2213940
