Clicking outside the Vue component will clear the autocomplete field text

I am currently working on an autocomplete field. When a user enters text that matches the result set, the dropdown result will populate. If there is no match, clicking outside the field will forcefully reset the input.

To achieve this functionality, I have implemented a custom Vue directive called click outside.

    // Code for click outside directive

An example of using the autocomplete field in form fields:

<div v-if="field.type == 'autocomplete'">
                <vu-auto-complete
                    v-model="fieldvalues[field.key]"
               :items="formFieldAutocompleteItems[fieldvalues[field.key]] || []"
                    :label="labelrequired(field)"
                    :placeholder="field.placeholder"
                    :error-message="errorMsg[field.key]"
                    @input="handleOnInput($event, field)"
                    @selected="getSelectedData($event, field)"
                >
                </vu-auto-complete>
            </div>

Methods for handling input in the autocomplete field:

// Code for handleOnInput method

The autocomplete field is functioning correctly. However, I require a directive or method to reset any input by clicking outside. Any suggestions or examples would be greatly appreciated.

One way to enhance your project is by utilizing the helpful onClickOutside tool from VueUse.

VueUse is a fantastic resource filled with numerous practical utility functions tailored for Vue, compatible with Vue2, Vue3, and Typescript.

With over 90 diverse utilities catering to varying needs, this library is designed to be lightweight, allowing you to include only what you need.

When using the onClickOutside feature, you'll need to specify a target ref, a callback function, and optionally configure it further with a third parameter.

You can implement it with a snippet like this:

onClickOutside(
  inputRef,
  (event) => {
    console.log(event);
    this.inputText = '';
  },
  { event: 'mousedown' }
)

This functionality streamlines the process, eliminating the need for creating custom code that might overlook key aspects like accessibility. Feel free to dive into the source code of the utility to delve deeper into its inner workings.
