Event binding
To bind functions to events within the Hello Retail script, you can include the following JavaScript snippet anywhere on your site. It can be used any time, before and after the script is loaded.
_awev=(window._awev||[]);_awev.push(["{action}", "{event-name}", callback]);
There are the following options for action
and event-name
:
Action | Description |
---|---|
bind |
The callback will be called each time the event name occurs. If 'name' has already occurred, the callback will be called once immediately (no matter how many times 'name' previously occurred). |
bind_once |
The callback will be called once, when 'name' first occurs. If 'name' has already occurred, the callback will be called immediately, and never again. |
unbind |
If you no longer want to receive callbacks for an event, you can unbind it by specifying the same name and callback as you used when binding. Note that it must be the same instance of the function that was bound. |
Event | Description |
---|---|
before_crawl |
Triggered before we look for product information on your site. |
context_ready |
Triggered when we have collected the URL of the current page, and found product information using cached selectors. |
crawl_completed |
Triggered when we have finished looking for product information (It will be triggered regardless of whether we actually found any info or not). |
user_avail |
Triggered when the script has retrieved user information from our backend. |
