function clickProceed() {
document.getElementById('DIV1').style.display = 'none';
document.getElementById('DIV2').style.display = 'inline';
}
</script>
<div id="DIV1" style="display:inline;">
Click to proceed:
<input type="button" value="Proceed" onClick="clickProceed();"></input>
</div>
<div id="DIV2" style="display:none;">
Click to share:
<div class="fb-share-button" data-href="http://www.stackoverflow.com"
data-width="500" data-type="button_count"></div>
