<head>
<!-- We don't recommend using github as a CDN. This is just for the example code-->
<script src="./dist/bundle.js"></script>
<title>Example Tracking Page</title>
</head>
<body>

<title>Example Tracking Page</title>
</head>
<body>
<form id='example_form'>
<input id="document_title" />
<input id="user_name" />
</form>
<script>
// Persist the current page context into the session. This helps us capture
// http parameters on a landing page which can be used later.
trkm.session.merge(trkm.context());
// setup a mapping between the page context and a form on the web page.
const contextToFormMap = {
formQuery: {
tag: 'form',
name: 'id',
value: 'example_form'
},
destination: [
{
// pull a value from document.title
pullFrom: {
source: {
type: 'context',
jsonPath: 'document.title'
}
},
// Find an input tag on the form using attribute name and the value
destination: {
tag: 'input',
name: 'id',
value: 'document_title'
}
},
{
pullFrom: {
required: false,
source: {
type: 'context',
jsonPath: 'document.url.urlParams.userName'
}
},
destination: { value: 'user_name' }
},
]
};
// At anytime, we can apply the mapping. formApply will find the
// HTMLFormElement on the page
trkm.formApply(contextToFormMap, trkm.session.get());
</script>
<p>The form field should contain the title of the page.</p>
