Troubles encountered when attempting to remove a Meteor.js collection with template event listeners

I am a Meteor beginner and I've been encountering some challenges that I need help with. I have set up a list of items in a Meteor (mongo) collection that can be accessed by both client and server. My goal is to be able to delete an item when clicking on a delete button next to it. So far, I have managed to input the data successfully and display it using the List template:

Inside my html file (client/list.html)

<template name=List>
  <table class="table">
    <tr>
      <td>Item</td>
      <td>Description</td>
    </tr>
    <tr>
      <td>{{itemName}}</td>
      <td>{{description}}</td>
      <button class="btn" id="delete" type="submit">Delete</button>
    </tr>
</template>

In the js file (client/list.js)

Template.quickList.events({
  'click #delete': function(e, t){
    cl = Lists.findOne(t.data);
    Lists.remove({_id: cl._id});
  }
});

Note: If I use console.log(t.data), I receive a null value in the event listener within the list.js file.

I'm unsure what steps to take next to resolve this issue.

Answer №1

When events are managed by a template's event map, the data context of the template can be accessed using the this keyword. If your item represents the data context (which is likely if you are obtaining itemName and description without helpers), you can simply utilize this._id in the event handler.

<tr>
  <td>{{itemName}}</td>
  <td>{{description}}</td>
  <button class="btn" id="delete" type="submit">Delete</button>
</tr>

Code snippet for handling the event:

Template.quickList.events({
  'click #delete': function(event){
    Lists.remove(this._id);
  }
});
