我的代码在jsfiddle工作,但没有在浏览器中工作我不知道我错过了什么,请你检查一下并告诉我解决方案。我谷歌它,但我没有得到正确的解决方案,请帮助我 这是jsfiddle链接http://jsfiddle.net/pLTrJ/9/

theDiv.innerHTML = random;

jsfiddle已将其自动包装在onload
事件中。你还没有在HTML页面中这样做,所以当它在浏览器中运行时,你试图在渲染之前抓住div,所以theDiv
为空。
以下应该有效:
<!doctype html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"> </script>
</head>
<script type="text/javascript">
window.onload = function () {
var random = 0;
var theDiv = document.getElementById("showVal");
updateTheDiv(9, 0);
function updateTheDiv(inRange, inMin) {
random = (Math.random() * inRange + inMin) | 0;
theDiv.innerHTML = random;
var nextCall = (Math.random() * 1000) | 0;
setTimeout(function () {
updateTheDiv(inRange, inMin);
}, nextCall);
}
}
</script>
<body>
<div id="showVal">
</div>
</body>
</html>

在浏览器中尝试此操作;)
<!doctype html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"> </script>
</head>
<body>
<div id="showVal"></div>
</body>
<script type="text/javascript">
var random = 0;
var theDiv = document.getElementById("showVal");
updateTheDiv(9,0);
function updateTheDiv(inRange, inMin) {
random = (Math.random()*inRange+inMin)|0;
theDiv.innerHTML = random;
var nextCall = (Math.random()*1000)|0;
setTimeout(function() {
updateTheDiv(inRange, inMin);
}, nextCall);
}
</script>
</html>
(我只是将脚本放到底部。所以在设置元素后加载脚本。)
