Given some handlebars code like this: {{ui.select param1="foo" param2="bar"}} How could I find out where ui.select is defined? (I happen to be on Ember 2.13) because this contains a . this comes from a contextual component. so first find out where ui comes from. Probably you have something like this: {{#my-component as |ui|}} {{ui.select ...}} {{/my-component}} Then you have to check the my-component and find out what ui is assigned to in the {{yield}} . 来源： https://stackoverflow.com/questions/49390867/ember-handlebars-find-where-component-helper-variable-is-defined

问题 I have a nav bar that has special CSS that shows up when a link has the "active" class on it. It looks something like this: <ul> <li>{{link-to "routeName"}}<i class="icon-up"></i>{{/link-to}}</li> {{!-- more list items like the previous one... --}} </ul> However, when I click on the link with "routeName" , a rather expensive query is made that may be slow at times.
