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
addPollForElementbefore 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. addPollForElementpolls 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.
