Example 1

Below is a simple example how to use forms. It shows the minimum HTML and JavaScript you need to have a simple form. There is no form HTML as it get generated by the form.

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" type="text/css"
        href="https://rawgit.com/vitmalina/w2ui/master/dist/w2ui.min.css" />
</head>
<body>
    <div id="myForm" style="height: 350px; width: 800px"></div>
</body>
<script type="module">
import { w2form } from 'https://rawgit.com/vitmalina/w2ui/master/dist/w2ui.es6.min.js'
let form = new w2form({
    name: 'myForm',
    fields: [
        { name: 'first_name', type: 'text', required: true,
            html: {
                label: 'First Name',
                attr: 'style="width: 200px"'
            }
        },
        { name: 'last_name',  type: 'text', required: true,
            html: {
                label: 'Last Name',
                attr: 'style="width: 200px"'
            }
        },
        { name: 'comments',  type: 'textarea',
            html: {
                label: 'Comments',
                attr: 'style="height: 150px; width: 500px"'
            }
        }
    ],
    actions: {
        Reset() {
            this.clear()
        },
        Save() {
            this.save()
        }
    }
})
form.render('#myForm')
</script>
</html>

If you do not defined any HTML, it will be automatically generated. If you want to provide your own HTML template see how to do it in the next example.
