Tracking with no Anchor

[block:callout] { "type": "info", "title": "Only for special integrations", "body": "If you are using anchor links for your recommended items (as most websites integrating LiftIgniter do) you can skip this section." } [/block] `$p("track")` searches through anchors on a specified element, and adds tracking tag & event listeners on the recommended items. If you aren't using an anchor to link your recommendations, then you'll have to trigger the custom `widget_shown`, `widget_visible`, and `widget_click` events yourself by using `$p("send")`. This is all handled by `$p("track")` if you are using an `anchor` tag on your widget, but this doesn't handle other cases since options are too broad. For example, [block:code] { "codes": [ { "code": "$p(\"register\", {\n max: 5\n callback: function(resp) {\n // Process tags on URLs for tag tracking.\n resp.items = resp.items.map(function(item){\n // Adding a tag.\n // Make sure that the query parameter is handled correctly.\n // This example is simple so it doesn't cover all cases\n item.url = item.url + \"?li_source=LI&li_medium=widget_name\"\n })\n\n // Rendering widget\n var element = document.querySelector(\".recommendation-selector\") \n var template = \"some template\"\n element.innerHTML = $p(\"render\", resp.items)\n\n // Extract visible items on the widget\n var visible_items = resp.items.map(function(item){return item.url;})\n\n // Send widget_shown event\n $p(\"send\", \"widget_shown\", {\n // Array of URL of items returned by recommendation\n vi: JSON.stringify(visible_items),\n w: \"widget_name\",\n // LI if the recommendation is from LiftIgniter \n source: \"LI\"\n })\n \n // Recommendations correspond to each individual item area within widget\n var recommendations = querySelectorAll(\".recommendation-selector > div\")\n\n recommendations.foreach(\n function(element){\n // Attach an onClick event on each of the element DOM.\n element.onClick(function(){ \n $p(\"sendRobust\", \"widget_click\", { // using \"sendRobust\" to make sure click gets sent despite page redirection\n vi: JSON.stringify(visible_items), // list of visible items on widget\n w: \"widget_name\", // name of widget for performance tracking\n clickUrl: \"\", // url of the item being rendered on recommendation.\n source: \"LI\" // LI if the recommendation is from LiftIgniter \n })\n }\n ))\n \n // OPTIONAL for determining VCTR\n // Implement .onVisible function that executes given callback function\n // when the DOM is visible within user's screen.\n element.onVisible(function(){\n \t$p(\"send\", \"widget_visible\", {\n \t\tvi: visible_items, // list of visible items on widget.\n w: \"widget_name\", // name of widget for performance tracking\n \tsource: \"LI\" // LI if the recommendation is from LiftIgniter \n \t})\n })\n }\n})", "language": "javascript" } ] } [/block] [block:callout] { "type": "info", "title": "Click event handling: sendRobust", "body": "If you are trying to listen for a click event on a link, then you might want to make sure that the event is sent before redirection occurs.
