POCan I use javascript timer in a mobile browser
text
Body
copied!<p>I am using IE in a mobile browser. I add a javascript function to a button that when the User clicks it says 'hello'.</p> <p>This works.</p> <p>I then add a timer.</p> <p>On a desktop browser it works.</p> <p>it does not work on my mobile browser.</p> <p>This is my code. (note I Had just tried placing an alert('hi'); in the swapImages() and that did not work either.</p> <pre><code> var div = document.getElementById('divImage'); var imgCached = document.getElementById('imgCached'); document.execCommand("BackgroundImageCache", false, true); function OnImgLoaded() { img1.src = imgCached.src; } var interval = 30; var _timer; var _index = 0; function test() { _timer = setInterval('swapImages()', interval); } function swapImages() { imgCached.onload = OnImgLoaded(); imgCached.src = 'my server url~/' + '0000' + _index + '.jpg'; _index = _index + 1; if (_index == 10) { _index = 0; clearTimeout(_timer); } } </code></pre> <p>UPDATE!! I had been runningit on Chrome desktop and not IE. I am mow testing it in IE desktop. I get the same erro so now I can debug.</p> <p>The error is this line: img1.src = imgCached.src;</p> <p>It tells me: Unable to get property 'src' of undefined or null reference</p> <p>I have changed the code to: var imgLive = document.getElementById('imgLive'); (I have renamed the img control)</p> <pre><code>function OnImgLoaded() { imgLive.src = imgCached.src; } </code></pre> <p>I get the same error.</p> <p>I look in Source and the control is correctly named..</p> <p>Thanks</p>
