View History

管理网页浏览历史记录，保存页面浏览记录，取出的记录内容进行数组化处理。IE6 和 IE7 需要第三方 JSON 库支持，推荐使用 json2.js。

相关文章和 DEMO

Parameters

• limit {number}

  保存数量，默认为 10。当该值为 0 时，无限保存。

• storeagekey {string}

  该工具使用 localStorage 保存信息，这是对应使用的 localStorage key。

• primaryKey {string}

  唯一属性，当指定属性相同，老的内容将替换成新的内容。默认为 url，因为页面 URL 通常不会重复。

Usage

引用 JavaScript 和初始化

<script src="view-history.js"></script>
<script>
if(typeof localStorage !== 'undefined' && typeof JSON !== 'undefined') {
	var viewHistory = new ViewHistory();
	viewHistory.init({
		limit: 5,
		storeagekey: 'viewHistory',
		primaryKey: 'url'
	});
}
</script>

保存页面信息

<script>
/* <![CDATA[ */
// 如果 ViewHistory 的实例存在，则可以将页面信息写入。
if(viewHistory) {
	var page = {
		"title": document.getElementsByTagName('title')[0].innerHTML,
		"url": location.href // 这是 primaryKey
		// "time": new Date()
		// "author": ...
		// 这里可以写入更多相关内容作为浏览记录中的信息
	};
	viewHistory.addHistory(page);
}
/* ]]> */
</script>

获取和显示浏览历史信息

<script>
/* <![CDATA[ */
var wrap = document.getElementById('view-history');

// 如果 ViewHistory 的实例存在，并且外层节点存在，则可显示历史浏览记录
if(viewHistory && wrap) {
	// 获取浏览记录
	var histories = viewHistory.getHistories();

	// 组装列表
	var list = document.createElement('ul');
	if(histories && histories.length > 0) {
		for(var i=histories.length-1; i>=0; i--) {
			var history = histories[i];

			var item = document.createElement('li');
			var link = document.createElement('a');
			link.href = history.url;
			link.innerHTML = history.title;

			item.appendChild(link);
			list.appendChild(item);
		}

		// 插入页面特定位置
		wrap.appendChild(list);
	}
}
/* ]]> */
</script>
