access iframe name from inside iframe
I though this would be simple enough but I can't find the answer. I need to know how I can access an iframe's name from within said iframe. I was trying something like this but it's not working.
<iframe name="thename">
<script type="text/javascript">
alert(parent.name);
</script>开发者_Go百科;
</iframe>
There is a combination of answers I prefer:
// window.frameElement Gets IFrame element which document inside
window.frameElement.getAttribute("Name");
It works on IE7+, Mozilla & Chrome
You were nearly right. Setting the name
attribute on a frame
or iframe
sets the name
property of the frame's global window
object to that string. (Not parent
, which refers to the window of the document that owns the frame.)
So unless some other script has deliberately changed the name, it's as simple as:
1.html:
<iframe name="tim" href="2.html"></iframe>
2.html:
<script type="text/javascript">
alert(window.name); // tim
</script>
in some cases window.frameElement
returns null
in iframe, so i figured workaround for it.
1. you need to set hash in src url of iframe
<iframe name="tim" href="2.html#your-hash"></iframe>
2. in iframe you can get this hash with
<script type="text/javascript">
var hash = window.location.hash;
</script>
Well, an IFRAME element shouldn't contain anything, it's targeting another document. So using a SCRIPT tag inside an IFRAME doesn't make alot of sense. Instead, use the SCRIPT inside the called document, e.g.
iframe_caller.html:
<html>
<body>
<iframe id="theIframe" name="theIframe" src="iframe_doc.html"></iframe>
</body>
</html>
iframe_doc.html:
<html>
<body>
<script type="text/javascript">
var iframes= parent.document.getElementsByTagName("iframe");
document.write(iframes[0].getAttribute("id"));
</script>
</body>
</html>
Note I'm using parent.document.function()
there.
Something like this should work:
parent.document.getElementById('idhere').name;
You have to use the parent and then get the element either byId, Name, etc... then access the name property.
So your code should be like:
<iframe name="thename">
<script type="text/javascript">
var iframeName = parent.document.getElementById('idhere').name;
</script>
</iframe>
