javascript - Return different subset of data when clicking checkbox in Meteor -

-

i trying make simple-todo app given on meteor website.

here's code or view complete app on meteorpad:

<body>   <div class="container">     <header>       <h1>todo list</h1>        <label class="hide-completed">         <input type="checkbox" checked="{{hidecompleted}}" />         hide completed tasks       </label>        <form class="new-task">         <input type="text" name="text" placeholder="type add new tasks" />       </form>      </header>      <ul>       {{#each tasks}}         {{> task}}       {{/each}}     </ul>   </div> </body> 
 template.body.helpers({      tasks: function() {          if (session.get("hidecompleted")) {              // if hide completed checked, filter tasks              return tasks.find({                  checked: {                      $ne: true                  }              }, {                  sort: {                      createdat: -1                  }              });          } else {              // otherwise, return of tasks              return tasks.find({}, {                  sort: {                      createdat: -1                  }              });          }      },      hidecompleted: function() {          return session.get("hidecompleted");      }  });

the hidecompleted checkbox not ommiting checked items list , after hours of braking head on it, still can't find bug. can please me out here?

you should use session.equals(key, value) test if session variable equal value.

in case be:

 template.body.helpers({     tasks: function(){         return session.equals("hidecompleted", true) ? tasks.find({checked: {$ne: true}}, {sort: {createdat: -1}}) : tasks.find({}, {sort: {createdat: -1}});     }   });

furthermore, need register click event invert corresponding session value:

 template.body.events({     "click #hide-tasks": function(e) {         e.preventdefault();         session.set("hidecompleted", !session.get("hidecompleted"));     }  }); 
<input id="hide-tasks" type="checkbox" checked="{{hidecompleted}}" />

here's updated meteorpad.
