Cannot access Xrm.Page.data from within HTML web resource in CRM 2011
I'm trying access the Xrm.Page.data object from within an HTML web resource that I have inserted onto a form in CRM 2011. However, depending on how I try to access the Xrm entity, I find that it is undefined or that Xrm.Page.data is null. The code for the web resource is as follows:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<script type="text/javascript">
function OpenMyApp(e){
alert('Xrm defined: ' + (typeof Xrm != 'undefined'));
// The line above returns the string 'Xrm defined: false'
alert('window.top.opener.parent.Xrm defined: ' + (typeof window.top.opener.parent.Xrm != 'undefined'));
// The line above returns the string 'window.top.opener.parent.Xrm defined: true'
alert('frames[0].Xrm defined: ' + (typeof frames[0].Xrm != 'undefined'));
// the line above will actually throw an error and stop the script, because the frames collection is empty.
alert(window.top.opener.parent.Xrm.Page.data);
// the line above returns null.
// var myId = Xrm.Page.data.entity.attributes.get("new_field_i_want").getValue();
// The line above is what I would like to see work.
e.preventDefault();
}
</script>
</head>
<body>
<a onClick="OpenMyApp(event);" href="#">My Link</a>
</body>
</html>
I've accessed Xrm.Page.data successfully from within a JavaScript function that is part of a library that fires upon a form event (for instance, Form.Load). It's just when it's embedded in an HTML web resource on the form that I run into this problem. Can anyone explain what I'm doing wrong, and if there is actually a way to access Xrm.Page.data in that way that I would like to do?
Thank you.
Answer
Try to access Xrm using following syntax:
window.parent.Xrm.Page.getAttribute()...
window.parent.Xrm.Page.getControl()...
window.parent.Xrm.Page.context...
like
alert(window.parent.Xrm.Page.data.entity.attributes.get("new_field_i_want").getValue());
From your sample code.
