How to Get Text Box Value In Ember.js?

In Ember.js, you can get the value of a text box using the Ember.TextField component. You can access the value of the text box by using the value property of the Ember.TextField component. By binding this property to a variable in your component or controller, you can retrieve the value entered by the user in the text box. This allows you to easily track and use the input from text boxes in your Ember.js application.

How to update the value of a text box dynamically in Ember.js?

In Ember.js, you can update the value of a text box dynamically by binding the text box to a property in your component or controller. Here's how you can do it:

1. Define a property in your component or controller that will hold the value of the text box. For example, you could define a property named "textBoxValue":

1
2
3
4
5
6

import Component from '@glimmer/component';
import { tracked } from '@glimmer/tracking';

export default class MyComponent extends Component {
  @tracked textBoxValue = 'Initial value';
}

1. Bind the value of the text box to the property you defined in the template using the value attribute. You can also add an input action that will update the property whenever the user types in the text box:

1

<input type="text" value={{this.textBoxValue}} {{on "input" this.updateTextBox}}>

1. Define the updateTextBox action in your component or controller that will update the value of the property whenever the user types in the text box:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

import Component from '@glimmer/component';
import { tracked } from '@glimmer/tracking';
import { action } from "@ember/object";

export default class MyComponent extends Component {
  @tracked textBoxValue = 'Initial value';

  @action
  updateTextBox(event) {
    this.textBoxValue = event.target.value;
  }
}

Now, whenever the user types in the text box, the value of the textBoxValue property will be updated dynamically. This allows you to track and manipulate the value of the text box in real time in your Ember.js application.

What are the steps to retrieve input data from a text box in Ember.js?

To retrieve input data from a text box in Ember.js, follow these steps:

1. Create a text box in your Ember template using the tag and bind it to a property in your component or controller using the value attribute:

1

<input type="text" value={{inputValue}} />

1. Define the inputValue property in your component or controller:

1

inputValue: ''

1. Add an onInput action to the text box to update the inputValue property as the user types:

1

<input type="text" value={{inputValue}} {{on "input" this.updateInputValue}}>

1. Implement the updateInputValue action in your component or controller to update the inputValue property:

1
2
3
4
5

actions: {
  updateInputValue(event) {
    this.set('inputValue', event.target.value);
  }
}

1. You can then access the value of the text box input by referencing the inputValue property in your component or controller.

What is the Ember.js route hook for accessing text box values?

In Ember.js, the route hook for accessing text box values is model. This hook is used to provide data to the template that corresponds to the route. To access the values of text boxes from a form, you can capture the values using the params argument of the model hook. For example, if you have a form with a text box for entering a name, you can access the value of this text box in the model hook like this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

// app/routes/my-route.js

import Route from '@ember/routing/route';

export default Route.extend({
  model(params) {
    return {
      name: params.name
    };
  }
});

In the above example, params.name would contain the value entered in the text box with the name attribute set to "name". You can then use this value in your template to display or manipulate it as needed.
