how to pass evaluated value of dot object field into function? about dot HOT 1 CLOSED

I resolved this by defining the function genSelect in my nodejs file and passing it into my dot template it object as a field.
`
// nodejs file
function genSelect (p1, p2, ...)
{
}
var dots = require("dot").process({ path: "./views"});
//...
var params = { "x":5};
params.genSelect = genSelect;
params.logLevel = 'info';
res.send(dots.config(params)); //

// end nodejs file
// begin config.dot file...
{{=it.genSelect('logLevel', 'logLevel', {"debug":"debug", "info":"info", "warn":"warn", "error":"error"}, it.logLevel) }}
// end config.dot file
`

from dot.
