我试图在 IE Mobile 中显示一张又一张的图像。以下代码在 IE Desktop 中有效,但如果我在 IE Mobile 中运行它,则会收到 [对象错误]。
这是代码:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript">
var interval = 30;
var _timer;
var _index = 0;
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<a href="#" title="Play Motion Clip from Beginning" onclick="test();">
<img alt="Play Motion" src="../Images/play_green_controls.png" style="border-style: none; width: 32px; height: 32px; background-color: #000000; cursor: pointer;" id="btnPlay" />
</a>
<img alt="" src="../0000.jpg" id="imgLive" />
<div id="divImage" style="width: 352px; height: 288px; display: none; background-image: url('Portal/Catalogues/000EC902F17F/3/2013/10/6/10/60b01a71-27f9-4122-ae8e-674e65a8b4dd/20131006102041027x75x0.04x0.40x.img00001.jpg');
background-repeat: no-repeat;">
</div>
<div id="divImageCache1" style="width: 352px; height: 288px; display: none;">
<img alt="" src="../0000.jpg" id="imgCached" />
</div>
</div>
</form>
<script type="text/javascript">
function test() {
try {
_timer = setInterval(swapImages(), interval);
}
catch (e) {
alert(e);
}
}
var imgCached = document.getElementById('imgCached');
var imgLive = document.getElementById('imgLive');
function OnImgLoaded() {
imgLive.src = imgCached.src;
}
function swapImages() {
imgCached.onload = OnImgLoaded();
imgCached.src = 'my irl/' + '0000' + _index + '.jpg';
_index = _index + 1;
if (_index == 10) {
_index = 0;
clearTimeout(_timer);
}
}
</script>
</body>
</html>
为了调试,我将 javascript 更改为:
<script type="text/javascript">
function test() {
try {
alert('hi1');
_timer = setInterval(swapImages(), interval);
alert('hi2');
}
catch (e) {
alert(e);
}
}
var imgCached = document.getElementById('imgCached');
var imgLive = document.getElementById('imgLive');
function OnImgLoaded() {
imgLive.src = imgCached.src;
}
function swapImages() {
alert('hi3');
imgCached.onload = OnImgLoaded();
imgCached.src = 'http://www.url.co.uk/Cloud/test/' + '0000' + _index + '.jpg';
_index = _index + 1;
if (_index == 10) {
_index = 0;
clearTimeout(_timer);
}
alert('hi4');
}
</script>
发生的事情是我得到'hi1','hi3','hi4'然后是对象错误。图像 DID 改变了一次。
