javascript：直到页面加载的时间 [英] javascript: time until page load

问题描述

在html中设置的图像为： < img src =/>

是否有javascript代码知道何时加载所有网页？
即ie直到onLoad（）事件被调用的时间

解决方案

你也许可以做这样的事情在页面底部

 < span id =imgsMsg>< / span> 
< script type =text / javascript> 
 var imgs = document.images; 
 var len = imgs.length; 
 var percent = 100; 
 var count = 0; 
 var messagecontainer = document.getElementById（imgsMsg）; 
 for（var i = 0; i< len; i ++）{
 imgs [i] .onload = function（）{
 count ++; 
 messagecontainer =（百分号 -  Math.floor（（100 / len）* count））+％loaded; //希望我的数学是正确的;）
} 
} 
< / script> 
< / body> 
  

i am writing a animation with javascript and want to print to user loading time until all images loaded.

images set in html as: <img src="" />

are there javascript code to know when all page loaded?
i.e time until onLoad() event called

解决方案

You might be able to do something like this at the bottom of the page

<span id="imgsMsg"></span>
<script type="text/javascript">
var imgs = document.images;
var len = imgs.length;
var percent = 100;
var count=0;
var messagecontainer = document.getElementById("imgsMsg");
for (var i=0;i<len;i++) {
   imgs[i].onload=function() {
     count++;
     messagecontainer = (percent - Math.floor((100/len)*count))+"% loaded"; // hope my math is correct ;)
   }
}
</script>
</body>
