Detailed documentation

evaluate()

Evaluates this template and returns an HtmlOutput object. Any properties set on this HtmlTemplate object will be in scope when evaluating. To debug errors in a template, examine the code using the getCode() method.

// A template which evaluates to whatever is bound to 'foo'.
var template = HtmlService.createTemplate('<?= foo ?>');
template.foo = 'Hello World!';
Logger.log(template.evaluate().getContent());  // will log 'Hello World!'

Return

HtmlOutput — an HtmlOutput object


getCode()

Generates a string of JavaScript code, based on the template file, that can be evaluated. This method produces a string of JavaScript code based on the template file. Calling eval(<code>) will return a new HtmlOutput object with the content of the template after running all embedded server scripts. The generated code is intended to be human-readable, and so if you need to debug a template you can call Logger.log(<code>) to see what was produced.

Evaluating this code will implicitly bind in all variables in the current scope. In general, it's preferable to use the evaluate() method, which takes explicit bindings.

var template = HtmlService.createTemplate('<b>The time is &lt;?= new Date() ?&gt;</b>');
Logger.log(template.getCode());

Return

String — a string based on the template, which can be evaluated


getCodeWithComments()

Generates a string of JavaScript code that can be evaluated, with each line of the code containing the original line from the template as a comment. This method produces a string of JavaScript code based on the template file. Calling eval(<code>) will return a new HtmlOutput object with the content of the template after running all embedded server scripts.

var template = HtmlService.createTemplate('<b>The time is &lt;?= new Date() ?&gt;</b>');
Logger.log(template.getCodeWithComments());

Return

String — an string based on the template, which can be evaluated


getRawContent()

Returns the unprocessed content of this template.

var template = HtmlService.createTemplate('<b>The time is &lt;?= new Date() ?&gt;</b>');
Logger.log(template.getRawContent());

Return

String — the template's raw content
