__CR.watchers is a member in the ConversionRuler JavaScript Global, and is of type array. It represents a queue of functions to run, intermittently, to check for a condition which may exist on the page. The functions in this queue are run several times a second to monitor the DOM and the page for changes to the page which may represent Conversion Actions.
The passed in watcher function will be called several times a second until the function returns the exact value of false – any other value returned will leave the watcher function in the queue indefinitely, or until the function returns false.
Example usage:
<script>
__CR.watchers.push(function (cr) {
if (document.getElementById('message-sent')) {
cr.track("newsletter", null, cr.data("email"));
return false;
}
});
</script>
The signature of the function added to this queue is function (cr) { }, and
The first parameter is the ConversionRuler JavaScript Global (e.g. __CR) and the value for this in the passed-in function is typically set to the browser global object window.
This function should be used when a browser web application or web form modifies the DOM and you need to monitor the DOM for changes.
This functionality is only available as of September 12, 2018.
