To dynamically add and remove views with Ember.js, you can use the {{#each}} helper to iterate over an array of objects and dynamically render views based on the data. Here is a basic example of how you can achieve this:
- Define an array of objects in your Ember controller or component:
1 2 3 4 5 6 7 |
// app/controllers/my-controller.js
import Controller from '@ember/controller';
export default Controller.extend({
items: ['Item 1', 'Item 2', 'Item 3']
});
|
- Use the {{#each}} helper in your template to dynamically render views for each item in the array:
1 2 3 4 5 |
<!-- app/templates/my-template.hbs -->
{{#each items as |item|}}
<div>{{item}}</div>
{{/each}}
|
- To add or remove items from the array dynamically, you can use Ember actions to modify the array:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
// app/controllers/my-controller.js
import Controller from '@ember/controller';
export default Controller.extend({
items: ['Item 1', 'Item 2', 'Item 3'],
actions: {
addItem() {
this.get('items').pushObject('New Item');
},
removeItem(item) {
this.get('items').removeObject(item);
}
}
});
|
- You can then trigger these actions in your template using buttons or other UI elements:
1 2 3 4 5 6 7 |
<!-- app/templates/my-template.hbs -->
{{#each items as |item|}}
<div>{{item}} <button {{action 'removeItem' item}}>Remove</button></div>
{{/each}}
<button {{action 'addItem'}}>Add Item</button>
|
By following these steps, you can dynamically add and remove views in your Ember.js application based on user interaction or changes in data.
