handlebars.js - handlebar comparison operator inside each loop -

i have 2 type of value on handlebar page , needs compare first 1 second. can print value of following code

{{articledetails.content_writer_id}} 

before writing each loop on page. want compare value following. can not scope of articledetails.content_writer_id in below code.

{{#each contentwriterdetails}}        {{#compare this.id "==" articledetails.content_writer_id }} 

i have registered compare helper using code.

 handlebars.registerhelper('compare', function (lvalue, operator, rvalue, options) { var operators, result; if (arguments.length < 3) {     throw new error("handlerbars helper 'compare' needs 2 parameters"); }  if (options === undefined) {     options = rvalue;     rvalue = operator;     operator = "==="; }  operators = {     '==': function (l, r) { return l == r; },     '===': function (l, r) { return l === r; },     '!=': function (l, r) { return l != r; },     '!==': function (l, r) { return l !== r; },     '<': function (l, r) { return l < r; },     '>': function (l, r) { return l > r; },     '<=': function (l, r) { return l <= r; },     '>=': function (l, r) { return l >= r; },     'typeof': function (l, r) { return typeof l == r; } };  if (!operators[operator]) {     throw new error("handlerbars helper 'compare' doesn't know operator " + operator); }  result = operators[operator](lvalue, rvalue);  if (result) {      return options.fn(this); } else {      return options.inverse(this); }   }); 

and above helper working fine have checked that.

any appreciated.

use parent's context path:

{{#each contentwriterdetails}}        {{#compare this.id "==" ../articledetails.content_writer_id }}
