ch02_01.jstoch02_06.js. - Open a new file named
ch02_06.jsand replace the definition offormBasewith the following code:var formBase = { items: [{ xtype: 'sliderfield', name : 'height', label: 'Height', minValue: 0, maxValue: 100, increment: 10 }] }; - Include
ch02_06.jsin place ofch02_05.jsinindex.html. - Deploy and access the application in the browser.
How it works...
