Step 1: Load the Facebook JavaScript SDK Make sure the SDK is loaded on your page. If your script runs after the SDK loads,
If you’ve tried the standard onclick event, you already know it doesn’t work. The Like button is embedded inside an iframe (sandboxed from your page). You cannot directly attach a jQuery click handler to elements inside an iframe from the parent document.
