Vue NumberInput Component

The NumberInput component for Vue represents a widget that allows you to input currency, percentages and any type of numeric data. The edited data can be presented in various formats.

Prerequisites

Refer to Vue Getting Started before you start with this help topic.

Configuration

After you have created your App.vue file, here is how you should structure it:

The NumberInput component for Vue requires the following import:

import JqxNumberInput from "jqwidgets-scripts/jqwidgets-vue/vue_jqxnumberinput.vue";

Add the jqxNumberInput component to the components section of the the Vue class:

 components: {
    JqxNumberInput
 },

Template

The App.vue has a <template> structural tag where we determine the application structure. There we will also set the tags for the new components - <JqxNumberInput/>

<template>
    <JqxNumberInput :width="width" :height="height"
                    :spinButtons="spinButtons">
    </JqxNumberInput>
</template>

Properties

The properties of the <JqxNumberInput/> component are defined in the data member of the Vue class. We should put them in the return object of the data function:

data: function () {
    return {
        width: 250,
        height: 25,
        spinButtons: true
    }
}

Events

The events in Vue are set as an attribute with @ prefix, for example:

<JqxNumberInput @valueChanged="onValueChanged()"
                :width="width" :height="height"
                :spinButtons="spinButtons">
</JqxNumberInput>

All events that are bound to a component are implemented in the methods member of the Vue class.

methods: {
    onValueChanged: function () {
        // Do something...
    }
}

Methods

To use a component's method we should have its reference. In Vue we refer to a component by the special $refs property. Before that we need to add the desired name reference to that component:

<JqxNumberInput ref="numberinput"></JqxNumberInput>

Here how you can use a component's method:

this.$refs.numberinput.getDecimal();

methods: {
    // Add here all used callbacks and/or events
    onValueChanged: function () {
        // Do something...
        let decimal = this.$refs.numberinput.getDecimal();
        alert(decimal);
    }
}

If we want to add additional methods we should also implement them in the methods member.

In case we need to do some precalculation or something else before the components are rendered, we should use the beforeCreate member. It depends on the case.

If you have followed the above steps, you App.vue file would look like this:

App.vue:

<template>
    <JqxNumberInput ref="numberinput" @valueChanged="onValueChanged()"
                    :width="width" :height="height"
                    :spinButtons="spinButtons">
    </JqxNumberInput> 
</template>
 
<script>
    // Import the components that will be used
    import JqxNumberInput from "jqwidgets-scripts/jqwidgets-vue/vue_jqxnumberinput.vue";
    
    export default {
        components: {
        // Adding imported widgets here
            JqxNumberInput
        },
        data: function () {
            // Define properties which will use in the widget
            return {
                width: 250,
                height: 25,
                spinButtons: true
            }
        },        
        beforeCreate: function () {            
            // Add here any data where you want to transform before components be rendered
        },
        methods: {
            // Add here all used callbacks and/or events
            onValueChanged: function () {
                // Do something...
                let decimal = this.$refs.numberinput.getDecimal();
                alert(decimal);
            }
        }
    }
</script>
