These days working i am working with handlerbars.js and it seems pretty interesting. In there i need a small help from you guys.
i have a following json input
"ALERTS": [
{
"alert_description": "ALCOHOL",
},
{
"alert_description": "DIAGNOSIS",
}
]
and i need to write a template to create following comma separated string.
ALCOHOL, DIAGNOSIS
i was able to print these values using line by line using following template.
<div>
<div>
{{#each this}}
<span>{{alert_description}}</span>
{{/each}}
</div>
</div>
can you guys please help me to solve this issue? appreciate your help
Thanks Keth
You can do this without writing a helper by using {{#each}} and testing the implicit @index variable:
{{#each this}}
{{#if @index}}, {{/if}}
<span>{{alert_description}}</span>
{{/each}}
You can also test @first and @last (see handlebarsjs docs).
