在车把助手中使用变量

Question

I have a handlebars helper that compares two values. My code is below

{{#compare action "blank" operator="!="}}
<button type="button" class="btn btn-primary btn-xs btn-approval" data-id="{{../sid}}" data-table="distributor">Approve</button>
<button type="button" class="btn btn-danger btn-xs btn-delete-approval" data-id="{{../sid}}" data-table="distributor">Delete</button>
{{/compare}}

for some reason I can't access the sid variable inside the helper. How would I do that?

Answer 1

Pass sid it as parameter to helper. And you can access it as an argument in helper function.

{{#compare ../sid  action "blank" operator="!="}}
      <button type="button" class="btn btn-primary btn-xs btn-approval" data-id="{{sid}}" data-table="distributor">Approve</button>
      <button type="button" class="btn btn-danger btn-xs btn-delete-approval" data-id="{{sid}}" data-table="distributor">Delete</button>
{{/compare}}

The helper function can then access it as an argument.

Handlebars.registerHelper('compare', function(sid, action, blank, operator, options) {
    this.sid = sid;
    // your code here...
});
