帝國cms 點贊功能的快速簡單實現方式

第一步，給你要點讚的a標籤或者button按鈕添加 id="dianzan" 屬性

第二步，給你需要顯示點贊數的標籤加上 class="likes-count" 屬性

第三步，將下面的js代碼放到你網站內容頁

<script>
function makeRequest(url, callback, method) {
  var xhr = new XMLHttpRequest();
  xhr.open(method, url);
  xhr.onreadystatechange = function() {
	if (xhr.readyState === 4 && xhr.status === 200) {
	  callback(xhr.responseText);
	}
  };
  xhr.send();
}

function updateLikes(event) {
  event.preventDefault(); // 阻止默認鏈接行爲

  var likesCountElement = document.querySelector('.likes-count');
  var likeButton = document.getElementById('dianzan');
  var url = "/e/public/digg/?classid=[!--classid--]&id=[!--id--]&dotop=1&doajax=1&ajaxarea=diggnum";

  makeRequest(url, function(responseText) {
	var responseArray = responseText.split("|");
	var likes = responseArray[0];
	likesCountElement.textContent = likes;

	alert(responseArray[2]);
  }, "GET");
}

var likeButton = document.getElementById('dianzan');
likeButton.addEventListener('click', updateLikes);
</script>

完成！
