Format in Vue Range slider component

16 Mar 20237 minutes to read

The format feature used to customize the units of Slider values to desired format. The formatted values will also be applied to the ARIA attributes of the slider. There are two ways of achieving formatting in slider.

  • Use the format API of slider which utilizes our Internationalization to format values.

  • Customize using the events namely renderingTicks and tooltipChange.

<template>
    <div id="app">
    <ejs-slider id='format' :value='value' :min="min" :max="max" :step="step"
    :tooltip="tooltip" :ticks="ticks" ></ejs-slider>
  </div>
</template>
<script>
import Vue from "vue";
import { SliderPlugin } from "@syncfusion/ej2-vue-inputs";
Vue.use(SliderPlugin);

export default {
  data() {
    return {
      min: 0, max: 100, step: 1, value: 30,
    // Applying currency formatting for tooltip with two decimal specifiers
    tooltip: { isVisible: true, format: 'C2' },
    // Applying currency formatting for ticks with two decimal specifiers
    ticks: { placement: 'After', format: 'C2', largeStep: 20, smallStep: 10, showSmallTicks: true }
    };
  }
}
</script>
<style>
  @import "../node_modules/@syncfusion/ej2-base/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-vue-buttons/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-vue-popups/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-vue-inputs/styles/material.css";
   #app {
    height: 40px;
    left: 30%;
    position: absolute;
    top: 40%;
    width: 50%;
  }
</style>

Using format API

In this method, we have different predefined formatting styles like Numeric (N), Percentage (P), Currency (C) and # specifiers. In this below example, we have formatted the ticks and tooltip values into percentage.

<template>
    <div id="app">
    <ejs-slider id='api' :value='value' :min="min" :max="max" :step="step"
    :tooltip="tooltip" :ticks="ticks" ></ejs-slider>
  </div>
</template>
<script>
import Vue from "vue";
import { SliderPlugin } from "@syncfusion/ej2-vue-inputs";
Vue.use(SliderPlugin);

export default {
  data() {
    return {
    min: 0, max: 1, value: 0.3, step: 0.01,
    // Assigning ticks values to percentage formatting
    ticks: { placement: 'After', largeStep: .2, smallStep: .1, showSmallTicks: true, format: 'P0' },
    // Assigning tooltip values to percentage formatting
    tooltip: { placement: 'Before', isVisible: true, showOn: 'Always', format: 'P0' }
  }
}
}
</script>
<style>
  @import "../node_modules/@syncfusion/ej2-base/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-vue-buttons/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-vue-popups/styles/material.css";
  @import "../node_modules/@syncfusion/ej2-vue-inputs/styles/material.css";
   #app {
    height: 40px;
    left: 30%;
    position: absolute;
    top: 40%;
    width: 50%;
  }
</style>

Using Events

In this method, we will be retrieving the values from the slider events then process them to desired formatted the values. In this sample we have customized the ticks values into weekdays as one formatting and tooltip values into day of the week as another formatting.

<template>
    <div id="app">
    <ejs-slider id='events' :value='value' :tooltip="tooltip" :ticks="ticks" :min="min" :max="max" :renderingTicks="renderingTicks" :tooltipChange="tooltipChange"></ejs-slider>
  </div>
</template>
<script>
import Vue from "vue";
import { SliderPlugin } from "@syncfusion/ej2-vue-inputs";
Vue.use(SliderPlugin);

export default {
  data() {
    return {
       // Minimum value
        min: 0,
        // Maximum value
        max: 6,
        // Slider current value
        value: 2,
        // Assigning ticks data
        ticks: {
            placement: 'After',
            largeStep: 1
        },
        // Assigning tooltip data
        tooltip: {
            placement: 'Before',
            isVisible: true
        }
    };
  },
  methods: {
       renderingTicks: function (args) {
                // Weekdays Array
                var daysArr = ['Sunday','Monday','Tuesday','Wednesday','Thrusday','Friday','Saturday'];
                // Customizing each ticks text into weeksdays
                args.text = daysArr[parseFloat(args.value)];
        },
        tooltipChange: function (args) {
                // Customizing tooltip to display the Day (in numeric) of the week
                args.text =  'Day ' + (Number(args.value) + 1).toString();
        }
  }
}
