我有以下代码在chrome中有效,但在FF或IE中不起作用。
该代码允许用户选择文本文件并每10秒重新读取一次内容,并使用文本文件的内容更新PRE标记。
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Read text file every 10 seconds</title>
<script type="text/javascript">
var currentIntervalId = undefined;
var startOrRestart = function(that) {
if (currentIntervalId !== undefined) clearInterval(currentIntervalId);
readText(that); // For executing immediately
currentIntervalId = setInterval(function() { readText(that); }, 10000);
};
function readText(that){
if(that.files && that.files[0]){
//alert("hello");
var reader = new FileReader();
reader.onload = function (e) {
var contents = e.target.result;//.replace("\r\n","<br/>");
contents = contents.replace(/&/g, '&').replace(/</g, '<').replace(/>/g, '>').replace(/"/g, '"');
document.getElementById('board').innerHTML= contents;
};//end onload()
reader.readAsText(that.files[0]);
}//end if html5 filelist support
}
</script>
</head>
<body>
<input type="file" onchange='startOrRestart(this)' /> <hr />
<pre id="board" contenteditable = "true">
This is where the text from the chosen text file will be loaded.
</pre>
</body>
</html>

有人可以帮助其在其他浏览器中使用吗?
提前致谢。
