The addPollForElement
method is used to add a delay to the trackData
method call until some element on the page exists. This method is useful if you added calls to the Monetate JavaScript API in the page <head>
element with the Monetate tag. This configuration could cause track to occur before a page loads, resulting in actions that don't execute on the page.
Before implementing the addPollForElement
method, be aware of these additional considerations:
- If you want to delay track with polling, you must call
addPollForElement
before you calltrackData
. - You can pass any valid CSS selector as the second parameter in
addPollForElement
. - When the polling function completes successfully, it's deleted and isn't evaluated again on subsequent retracks unless you add another call to
addPollForElement
. addPollForElement
polls every 50 milliseconds for 5 seconds or until the designated element is found. Monetate tracks regardless of whether the element is found or the poll times out.
