If I understand you correctly, your problem is to re-render the DIVautomatically. So there are a number of ways you can force an elementto re-render (without a reload) - the most effective one I found was to quickly switch the displaystyle of the elementin question.

如果我理解正确，您的问题是DIV自动重新渲染。因此，您可以通过多种方式强制element重新渲染（无需重新加载）——我发现最有效的方法是快速切换相关display样式element。

That is:

那是：

Set the displayproperty to none:

将display属性设置为none：

element.style.display = 'none';

and then return it to block

然后将其返回到 block

element.style.display = 'block';

Here is the working demo of your example in JSFiddle.

Here is an example of how you can update the content of a div without reloading the page. It's a bit unclear what you want from your question so I hope this helps.

下面是一个示例，说明如何在不重新加载页面的情况下更新 div 的内容。有点不清楚你想从你的问题中得到什么，所以我希望这会有所帮助。

html

html

<div id="divID"></div>

javascript

var counter = 1;
var auto_refresh = setInterval(
function () {
    var newcontent= 'Refresh nr:'+counter;
    $('#divID').html(newcontent);
    counter++;
}, 1000);

You can't load just a part of the page just like that. But you can load all the page and fetch just the part you want. eg:

你不能像那样只加载页面的一部分。但是您可以加载所有页面并只获取您想要的部分。例如：

$.get('anoter_page.html',function(data){
myDiv = $(data).find('#divID');
$('#divID').html(myDiv.html());
})
