Changing the value using Slider

This recipe describes the use of the Slider form field, which allows the user to change the value by merely sliding.

Getting ready

Make sure that you have set up your development environment by following the recipes outlined in Chapter 1.

Make sure that you have followed the Get your form ready with FormPanel recipe in this chapter.

How to do it...

Carry out the following steps:

  1. Copy ch02_01.js to ch02_06.js.
  2. Open a new file named ch02_06.js and replace the definition of formBase with the following code:
    var formBase = {
      items: [{
        xtype: 'sliderfield',
        name : 'height',
        label: 'Height',
        minValue: 0,
        maxValue: 100,
        increment: 10
      }]
    };
  3. Include ch02_06.js in place of ch02_05.js in index.html.
  4. Deploy and access the application in the browser.

How it works...

The preceding code creates a slider field with 0–100 as the range of values, with 10 as the increment, which means when a user clicks on the slider, the value will change by 10 on every click. The increment value must be a whole number.
