Track only iframe history
- by evanwong
I have a page which contains an iframe and I want to track the history of the iframe only.
I tried to use the history object like this:
<!DOCTYPE html>
<html>
<head>
<title></title>
<script type="text/javascript">
function checkFrameHistory() {
alert(window.frames["test2"].history.length);
}
function checkThisHistory() {
alert(history.length);
}
</script>
</head>
<body>
<iframe name="test2" src="test2.html"></iframe>
<div>
<input type="button" onclick="checkFrameHistory()" value="Frame history"/>
<input type="button" onclick="checkThisHistory()" value="This history"/>
</div>
</body>
</html>
test2.html
<!DOCTYPE html>
<html>
<head>
<title></title>
<script type="text/javascript">
function checkMyHistory() {
alert(history.length);
}
</script>
</head>
<body>
<div>
Test2
</div>
<div>
<input type="button" onclick="checkMyHistory()" value="My history"/>
</div>
</body>
</html>
but it actually gave me the history including the parent window.
For instance, I went to another site in the main window and came back to my iframe test site. Both window.frames["test2"].history.length and history.length still gave me the same count by increasing the length by 2.
Did I do it wrong? Is there a way to track only the iframe history?
