Question

Hi I want to check the string response in HB. I've tried this:

{{#if status=='false'}}
    {{console.log("hi");}}
{{else}}
   {{console.log("no");}}
{{#endif}}

How can I check the response simple? I want to show a message if it's true and another message if it's false.

Handlebars is designed to be very simple and doesn't have this functionality out of the box. You should pass the status as a boolean rather than a string, then just use an if statement:

{{#if status}}
    {{console.log("hi");}}
{{else}}
   {{console.log("no");}}
{{#endif}}

You could also write a helper function:

Handlebars.registerHelper('ifEq', function(a, b, options) {
  if (a == b) return options.fn(this)
  else return options.inverse(this)
});

Then your handlebars becomes:

{{#ifEq status 'true'}}
  Hello
{{else}}
  No
{{/ifEq}}
