js中使用document输出信息时，总是有进度条
?
在firefox下，显示正常，但是进度条总显示正在加载。
后来发现是我忘了关闭document；
写到当前的文档：
<html><head><title>write example</title><script type="text/javascript">function newContent(){alert("load new content");document.open();document.write("<h1>Out with the old - in with the new!</h1>");document.close();}</script></head><body onload="newContent();"><p>Some original document content.</p></body></html>写的新打开的文档，或者 iframe<html>
<head>
<title>Write to IFRAME </title>
</head>
<body>
<iframe width="50%" height="100" id="iframe1" src=""></iframe>
<script language="JavaScript">
<!–
var str = ‘Hello I am sending this to <b>IFRAME</b>’;
// NO IE
if (!document.all) {
????? var ifr1 = document.getElementById(‘iframe1′);
????? ifr1.contentWindow.document.open();
????? ifr1.contentWindow.document.write(str);
????? ifr1.contentWindow.document.close();
}
// IE
else {
document.frames[0].document.open();
document.frames[0].document.write(str);
document.frames[0].document.close();
}
//–>
</script>
</body>
</html>
?
这里还有个比较复杂的例子等等研究一下<html>
<head>
<title>Write to IFRAME </title>
</head>
<body>
<script language="javascript">
var txt="";
function handleErr(msg,url,l)
{
txt="There was an error on this page.nn"
txt+="Error: " + msg + "n"
txt+="URL: " + url + "n"
txt+="Line: " + l + "nn"
txt+="Click OK to continue.nn"
alert(txt)
return true
}
onerror=handleErr
function loadExternal(url) {
? var ifr1 = document.getElementById(‘srcFrame’);
? if (ifr1) {
????? ifr1.contentWindow.document.location = url;
??? //window.frames['srcFrame'].location? = url;
??? return false;
? }
? return true;
}
function GetInnerHTML () {
????? var str = null;
????? if (!document.all) {
??????????? var ifr1 = document.getElementById(‘srcFrame’);
????????????????? str = ifr1.contentWindow.document.documentElement.innerHTML;
????? }
????? else {
????????????????? str = window.frames['srcFrame'].document.body.innerHTML;????????????
????? }
????? return (str);
}
function displayExternal() {
????? var str = GetInnerHTML ();
????? if (!str) { alert (‘Could not read contents of source iframe’); return; }
????? if (!document.all) {
??????????? var ifr1 = document.getElementById(‘trgFrame’);
??????????? ifr1.contentWindow.document.open();
??????????? ifr1.contentWindow.document.write(str);
??????????? ifr1.contentWindow.document.close();
????? }
????? // IE
????? else {
??????????? window.frames['trgFrame'].document.body.innerHTML = str;
??????????? /*
??????????? ifr1.document.open();
??????????? ifr1.document.write(str);
??????????? ifr1.document.close();
??????????? */
????? }
}
</script>
