javascript 对象 实例

javascript是面向对象的脚本语言，如果不懂对象的使用，那对javascript的掌握也谈不上熟悉了，只能说是了解而已，所以最近这段时间，我猛攻了一下javascript对象，学习了

很多实例，对javascript对象多少有点了解了，哈哈，以免自己以后忘记，我写了个小实例，供以后参考。

这个例子涉及的知识主要是Jquery，DOM，Javascript对象和prototype，以及数组。大意就是页面装载完毕之后，初始化一个数组。后面每隔3秒，调用getStatus函数，该函数

挑选数组中inrunning为3的元素，调用jquery方法，获取状态，当获取状态之后，使用新的状态刷新数组中相应元素的isrunning值，直到isrunning不为3。

	function getStatus() {
		
		var deployids = new Array();
		deployids.splice(0, deployids.length);
		
		for (var i = 0; i < tinfo.length; i++) {
			if (tinfo[i].isrunning === "3") {
				var deployid = tinfo[i].deployid;
				deployids.push(deployid);
			}
		}
		
		if (deployids.length > 0) {
			$.get("<%=path%>/testManage_getTestStatus", {Action:"get", deployids:deployids.toString(), async:false}, function(data) {
				var status = data.split(" ");
				for (var i = 0; i < deployids.length; i++) {
					var index = tinfo.get_index(deployids[i]);
					tinfo[index].isrunning = status[i];
					refresh(status[i], tinfo[index].tdid, tinfo[index].testid);
				}
			});
		}
	}
	
	function refresh(s, id, testid) {
		var div10 = "<div class=\"action create disabled\" alt=\"部署\" title=\"部署\"><span class=\"icon\"> </span></div>";
		var div11 = "<div class=\"action create\" alt=\"部署\" title=\"部署\"><span class=\"icon\"> </span></div>";

		if ("3" == s) {
			document.getElementById(id).innerHTML = 
				"<div width='100%' align='center'><image src='<%=request.getContextPath()%>/img/loading4.gif'></image></div>";
		} else if ("1" == s) {
