There are various hooks available within the personalization lifecycle to allow you to attach logic to these hook points for automation.

To use them, you must create functions matching the name of a signature of the hook function, and ensure the code is called at the appropriate time, for example, when a Slot has loaded.

The hooks you can use are as follows:

Before Slot load

Triggers

Once for each Slot, after the data has been retrieved, before the page is updated.

This hook can also be used to alter the HTML before it is added to the document by replacing the HTML attribute.

Hook function

window.frBeforeSlotLoad(slotID, data)

Parameters

Parameter	Type	Description
slotID	string	The ID of the Slot currently being processed.
data	object	The data generated by the server for the current Slot.

Example data value:

{
"html": "<h2>Hello World</h2>",
"css": null,
"js": null,
"var": {}, // Optional variables passed back from the server

meta: {
        "tmsb": "SmartBlock ID",
        "tmsl": "Slot ID"
        "tmrl": "Rule ID"
        "tmcs": "Content ID"
       }
}

Example

function frBeforeSlotLoad(slotID,data) { 
  console.log("Hook: BeforeSlotLoad fired",slotID,data); 
}

Return value

Boolean - If true, the Slot is added to the page as normal. If false, the Slot has not been added to the page.

On Slot load
