How to check equality of variables in handlebars?

Question

JavaScript

How can validation be implemented in this way? {{#if innNumber === this.inn}}YES!{{/if}}
innNumber is passed to the template function when called
. As a result, this is necessary so that in the loop when outputting from json, for example, highlight the line if the value matches

Answer 1

You can register Helper:

Handlebars.registerHelper('iff', function(v1, v2, options) {
  if(v1 === v2) {
    return options.fn(this);
  }
  return options.inverse(this);
});

And write like this:

{{#iff v1 v2}}
    {{v1}} === {{v2}}
{{else}}
    {{v1}} != {{v2}}
{{/iff}}
