How to Clear Form Data In Ember.js?

In Ember.js, to clear form data, you can call the reset method on the model associated with the form. This method will reset all attributes of the model to their original values, effectively clearing the form data. Additionally, you can also manually reset each attribute of the model to empty or null values if needed. Another way to clear form data in Ember.js is to create a function that resets all form fields individually, setting them to empty values. This approach gives you more control over the reset process and allows you to customize the behavior as needed.

How do I reset a form to its initial state in ember.js?

In Ember.js, you can reset a form to its initial state by using the 'rollbackAttributes' method of the model associated with the form.

For example, if you have a form for editing a 'user' model, you can reset the form by calling the 'rollbackAttributes' method on the 'user' model:

1
2
3
4
5

actions: {
  resetForm() {
    this.model.rollbackAttributes();
  }
}

Then, you can call this action in your template when the user clicks on a reset button:

1

<button {{action "resetForm"}}>Reset Form</button>

This will revert all changes made to the model back to its initial state, effectively resetting the form to its initial values.

How can I empty all input fields in ember.js?

You can empty all input fields in Ember.js by clearing the values of each input field individually or by resetting the form that contains the input fields. Here are a few ways you can achieve this:

1. Resetting the form: You can reset the form by calling the reset() method on the form element. In your Ember component or controller, you can access the form element by using the querySelector method or by using getElementById. Once you have a reference to the form element, you can call the reset() method on it to clear all input fields.

1
2

let formElement = document.querySelector('.my-form');
formElement.reset();

1. Clearing input fields individually: If you want to clear the input fields individually, you can iterate through all input fields in your component or controller and set their values to empty string.

1

this.element.querySelectorAll('input').forEach(input => input.value = '');

By using one of these methods you can empty all input fields in Ember.js.

What is the difference between clearing form data and resetting form data in ember.js?

In Ember.js, clearing form data and resetting form data are two different actions that can be performed on a form.

1. Clearing form data: Clearing form data typically refers to removing any input values that are currently present in the form fields. This action is useful in situations where you want to reset the form to its initial state, without necessarily resetting all of the form's state (such as any validation errors or form submission state). This can be done by simply setting the form field values to empty strings or null.
2. Resetting form data: Resetting form data usually involves more than just clearing the input values. It typically involves resetting the form to its initial state, which may include clearing the input values, resetting any validation errors, and resetting any other form state. In Ember.js, you can achieve this by resetting the model or form data to their initial values.

In summary, clearing form data refers to removing input values from form fields, while resetting form data involves resetting the entire form to its initial state, including input values, validation errors, and any other form state.
