addPollForElement

// addPollForElement Method
window.monetateQ = window.monetateQ || [];
window.monetateQ.push(["addPollForElement",
  "selector string"
])
window.monetateQ.push(["trackData"]);

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 call trackData.
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.

Code Sample

// addPollForElement Example
window.monetateQ = window.monetateQ || [];
window.monetateQ.push(["addPollForElement",
  "#topNav .subnav span"
])
window.monetateQ.push([
  "trackData"
]);
