Single-Page Applications

The events system replaces previous event tracking solutions, such as the JQuery extension. The Browser History Change, Page Load, and Hash Change event listeners are especially useful for single-page applications.

Setup

On a single-page application (SPA) where the page loads utag.js only once per visit, suppress the automatic page view tracking call to allow your application to make these calls directly.

To override the automatic page tracking add this line to your page prior to loading utag.js:

window.utag_cfg_ovrd = window.utag_cfg_ovrd || {};
window.utag_cfg_ovrd.noview = true

Once your application is loaded (and utag.js is loaded), trigger utag.view() tracking calls in your page code. These calls are typically triggered at the DOM-ready event or any event that causes a content view refresh. Learn more about the available settings to adjust the behavior of utag.js.

The utag_data object declared on initial page landing is not re-purposed with these calls. To use data from the initial page landing, it needs to be re-declared and passed again in the function call.

Global and Tag-scoped Extensions are executed during these calls. Pre-loader and DOM Ready extensions are not executed during these calls.

Track Views

Track views in single-page applications with the utag.view() function.

The following utag.view() function call demonstrates how to pass data using key-value pairs:

utag.view({ variable1:"VARIABLE1 VALUE", variable2:"VARIABLE2 VALUE", variable3:"VARIABLE3 VALUE" });

Examples

The following is a content site example in which a visitor searched for “politics”:

utag.view({tealium_event:"search", search_keyword:"politics", search_results: 42});

The following example demonstrates how to track views:

utag.view({
    "demo_site" : "Tealium React Demo",
    "demo_event" : "View " + name
})

Track Events

Track links and events in single-page applications with the utag.link() function.

If jQuery is installed you have the option to use the jQuery onHandler extension. This extension is configurable for specific event bindings to trigger the utag.link() and utag.view() functions. This allows you to avoid hard-coding the tracking logic in your side code.

The following utag.link() function call demonstrates how to pass data using key-value pairs:

utag.link({ variable1:'VARIABLE1 VALUE', variable2:'VARIABLE2 VALUE' });

Examples

The following is a content site example of tracking social media sharing actions:

utag.link({
    "content_id"         : "38121",
    "page_friendly_url" : "/travel/national_parks",
    "page_name"          : "Travel: National Parks",
    "social_network"     : "facebook",
    "tealium_event"      : "social_share"
})

The following ReactJS example, from the Tealium demo application, demonstrates how to track events for add, edit, save and remove function. Each function call triggers the utag.link() function.

add(text) {
    utag.link({
        "page_type": "react",
        "view_name": "board",
        "event_type": "click",
        "event_name": "add_note",
        "tealium_event": "add_note"
    })
    var notes = [
        ...this.state.notes,
        {
            id: this.nextId(),
            note: text
        }
    ]
    this.setState({notes})
}

edit() {
    utag.link({
        "page_type": "react",
        "view_name": "board",
        "event_type": "click",
        "event_name": "edit_note",
        "tealium_event": "edit_note"
    })
    this.setState({editing: true});
}
save() {
    utag.link({
        "page_type": "react",
        "view_name": "board",
        "event_type": "click",
        "event_name": "save_note",
        "tealium_event": "save_note"
    })
    this.props.onChange(this.refs.newText.value, this.props.id)
    this.setState({editing: false});
}
remove() {
    utag.link({
        "page_type": "react",
        "view_name": "board",
        "event_type": "click",
        "event_name": "remove_note",
        "tealium_event": "remove_note"
    })

    this.props.onRemove(this.props.id)
}
