This section explains how to use Syncfusion Vue MaskedTextBox components in Vue 3 application.

Prerequisites

System requirements for Syncfusion Vue UI components

Creating Vue application using Vue CLI

The easiest way to create a Vue application is to use the Vue CLI. Vue CLI versions above 4.5.0 are mandatory for creating applications using Vue 3. Use the following command to uninstall older versions of the Vue CLI.

npm uninstall vue-cli -g

Use the following commands to install the latest version of Vue CLI.

npm install -g @vue/cli
npm install -g @vue/cli-init

Create a new project using the command below.

vue create quickstart

Initiating a new project prompts us to choose the type of project to be used for the current application. Select the option Default (Vue 3) from the menu.

Reference

Adding Syncfusion MaskedTextBox package in the application

Syncfusion Vue packages are maintained in the npmjs.com registry.
The MaskedTextBox component will be used in this example. To install it use the following command.

npm install @syncfusion/ej2-vue-inputs --save

Adding CSS reference for Syncfusion Vue MaskedTextBox component

Import the needed css styles for the MaskedTextBox component along with dependency styles in the <style> section of the src/App.vue file as follows.

<style>
    @import "../node_modules/@syncfusion/ej2-base/styles/material.css";
    @import "../node_modules/@syncfusion/ej2-vue-inputs/styles/material.css";
</style>

Adding Syncfusion Vue MaskedTextBox component in the application

You have completed all the necessary configurations needed for rendering the Syncfusion Vue component. Now, you are going to add the MaskedTextBox component using following steps.

Import the MaskedTextBox component in the <script> section of the src/App.vue file.

<script>
import { MaskedTextBoxComponent } from "@syncfusion/ej2-vue-inputs";
</script>

import { MaskedTextBoxComponent } from "@syncfusion/ej2-vue-inputs";
//Component registeration
export default {
    name: "App",
    components: {
        'ejs-maskedtextbox': MaskedTextBoxComponent,
    }
}

Add the component definition in template section.

<template>
    <div class="control_wrapper">
        <ejs-maskedtextbox></ejs-maskedtextbox>
    </div>
</template>

Summarizing the above steps, update the src/App.vue file with following code.

```
<template>
    <div class="control_wrapper">
        <ejs-maskedtextbox></ejs-maskedtextbox>
    </div>
</template>
<script>
import { MaskedTextBoxComponent } from "@syncfusion/ej2-vue-inputs";
//Component registeration
export default {
    name: 'App',
    components: {
        "ejs-maskedtextbox": MaskedTextBoxComponent
    }
}
</script>
<style>
    @import "../node_modules/@syncfusion/ej2-base/styles/material.css";
    @import "../node_modules/@syncfusion/ej2-vue-inputs/styles/material.css";
    .control_wrapper {
        margin: 0 auto;
        width: 240px;
    }
</style>
```

Running the application

Run the application using the following command.

npm run serve

Set the mask

You can set the mask to the MaskedTextBox to validate the user input by using the
mask property. To know more about
the usage of mask and configuration, refer to this link.

The following example demonstrates the usage of mask element 0 that allows any single digit from 0 to 9.

```
<template>
    <div id="app">
        <div class='wrap'>
            <ejs-maskedtextbox mask='000-000-0000' placeholder='MaskedTextBox' floatLabelType='Always'></ejs-maskedtextbox>
        </div>
    </div>
</template>
<script>
import { MaskedTextBoxComponent } from "@syncfusion/ej2-vue-inputs";
//Component registeration
export default {
    name: 'App',
    components: {
        "ejs-maskedtextbox": MaskedTextBoxComponent
    },
    data () {
        return {}
    }
}
</script>
<style>
    @import "../node_modules/@syncfusion/ej2-base/styles/material.css";
    @import "../node_modules/@syncfusion/ej2-vue-inputs/styles/material.css";
    .wrap {
        margin: 0 auto;
        width: 240px;
    }
</style>
```

Output be like the below.

Model binding

In MaskedTextBox, the value property supports model binding functionality.

The following example demonstrates model binding functionality with the MaskedTextBox and HTML input element.

```
<template>
    <div id="app">
        <div class='wrap'>
            <div class='e-input-group' style='margin-bottom:30px'>
                <input class='e-input' type='text' v-model='value' placeholder='Mobile Number' />
            </div>
            <ejs-maskedtextbox v-model="value" :value="value" mask='000-000-0000'></ejs-maskedtextbox>
        </div>
    </div>
</template>
<script>
import { MaskedTextBoxComponent } from "@syncfusion/ej2-vue-inputs";
//Component registeration
export default {
    name: 'App',
    components: {
        "ejs-maskedtextbox": MaskedTextBoxComponent
    },
    data () {
        return {
            value : ''
        }
    }
}
</script>
<style>
    @import "../node_modules/@syncfusion/ej2-base/styles/material.css";
    @import "../node_modules/@syncfusion/ej2-vue-inputs/styles/material.css";
    .wrap {
        margin: 35px auto;
        width: 240px;
    }
</style>
```
