随随时间变化的随机值进行除法 [英] Div with random values that change with time
问题描述
我正在尝试在HTML页面中创建一个div并在其中写入随机值，然后，我希望div每X秒刷新一次自身，以使其中的数字发生变化，但不会重新加载整个页面，只是div.
I'm trying to create a div in an HTML page and write random value in it, then, I want the div to refresh itself every X seconds so that the number in it change, but the entire page is not reloaded, just the div.
我的想法是:
<body>
<div id="people" onload="rand();"> </div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
function autoRefresh_div()
{
$("#people").load("load.html");// a function which will load data from other file after x seconds
}
setInterval('autoRefresh_div()', 0.5); // refresh div after 5 secs
function rand(){
document.getElementById("people").innerHTML = Math.random();
}
</script>
</body>
</html>
但是我的div中没有任何内容.我尝试用一些文本更改"Math.random()"，但没有任何变化.
But nothing appear in my div. I tried to change "Math.random()" with some text but nothings change.
有人可以解释为什么吗?
Can someone explain me why?
推荐答案
您不需要onload事件. setInterval()带有将在div中设置新值的函数:
You don't need an onload event. Just setInterval() with a function which will set a new value in a div:
function autoRefreshDiv() {
document.getElementById("people").innerHTML = Math.random();
}
setInterval(autoRefreshDiv, 1000); // Time is set in milliseconds
<div id="people"></div>
setInterval将每X毫秒运行一次函数.
setInterval will run the function every X milliseconds.
