解释问题
所以我注意到在使用someElement.innerHTML时,DOM节点数增加了.
我猜这个引用被杀了,但是在垃圾收集器删除对象之前仍然会分配内存.
实施例(HTML)：
<html>
<head>
<Meta charset="utf-8">
<link rel="stylesheet" href="test.css">
<script src="script.js"></script>
</head>
<body onload="startTimer()">
<div id="timeContainer">Time Goes Here</div>
</body>
</html>
实施例(的JavaScript)：
var timer;
var body;
var oldTime = "";
var timeContainer;
function startTimer(){
timeContainer = document.getElementById("timeContainer");
timer = setInterval(getTime,10);
}
function getTime(){
var d = new Date();
var timeString = d.getUTCHours() +":"+ d.getUTCMinutes(); +":"+ d.getUTCSeconds();
if(timeString != oldTime){
oldTime = timeString;
timeContainer.innerHTML = timeString;
}
}
到目前为止我尝试了什么
>我尝试使用someElement.textContent.
>每次刷新计时器并创建一个新计时器时,我都删除了whoe ParentElement
题
解决方法
I guess that the reference is killed but the memory is still allocated
until the garbage collector deletes the object.
正确.
How can i avoid to increase the node count even once when im just
refreshing content?
你不能,也不应该担心它.这是浏览器的域,它在垃圾收集方面做了它想要做的事情(不同的浏览器可能会做不同的事情).
I deleted the whole ParentElement everytime it refreshes the timer and
created a new one
