Question

 {{somefunction(somevalue)}} 

thank you

Answer 1

Check out the section on Lambdas at https://mustache.github.io/mustache.5.html

Mustache template block:

{{#someFunction}}someValue{{/someFunction}} 

Function block:

someFunction : function () {   return function(val, render) {     return "I passed in this value: " + render(val);   }; } 

Output:

I passed in this value: someValue 

Answer 2

for me this works:

add general function FUNC to json (data):

 data.FUNC = function(){                 return function(val, render){                     var values = JSON.parse(render(val));                     return window[values.FUNCNAME].apply(this, values.FUNCARGS);                 };             }; 

regular javascript on page:

 function foo(arg1, arg2){     return "Arg1 is " + arg1 +  " and Arg2 is " + arg2; }; 

Mustache template block calling the regular javascript-function with tag-values as arguments:

{{#FUNC}}{"FUNCNAME":"foo", "FUNCARGS":["{{page}}","{{title}}"]}{{/FUNC}} 

you also can call a function defined in the json:

{{#calljsfunction}} {{#FUNC}}{"FUNCNAME":"{{calljsfunction}}", "FUNCARGS":["{{page}}","{{title}}"]}{{/FUNC}}{{/calljsfunction}}
