I have two type of value on handlebar page and needs to compare the first one from second. I can print value of following code
{{articledetails.content_writer_id}}
before writing each loop on page. Now i want to compare the value like following. but i can not get the scope of articledetails.content_writer_id in below code.
{{#each contentwriterdetails}}
{{#compare this.id "==" articledetails.content_writer_id }}
I have already registered compare helper by using this 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 the operator " + operator);
}
result = operators[operator](lvalue, rvalue);
if (result) {
return options.fn(this);
} else {
return options.inverse(this);
}
});
and above helper is working fine as i have checked that.
Any help would be appreciated.
Use the parent's context path:
{{#each contentwriterdetails}}
{{#compare this.id "==" ../articledetails.content_writer_id }}
