Get value into HTML web resource in Dynamics CRM Online
I am trying to get a value from Dynamics CRM into a HTML webresource. I have found this and tried to make the code out of it:
https://msdn.microsoft.com/en-us/library/jj602964(v=crm.7).aspx
It says to use var nameValue = Xrm.Page.getAttribute("name").getValue(); to get it out.
My Code is (the alert is just to try if it gets the right value):
<html><head>
<meta charset="utf-8">
</head>
<body>
<button onclick="getquotenumber()">Try it</button>
<script>
function getquotenumber() {
var getquote = Xrm.Page.getAttribute("quotenumber").getValue();
alert(getquote);
}
</script>
</body></html>
When clicking "Try it" nothing happens! What am I doing wrong?
Thanks, Johannes

As someone already mentioned in the comments, there is no Xrm.Page defined. You can add that by referencing ClientGlobalContext but you would not have gotten any attributes anyway, because this is using Xrm.Page.data under the covers and this is null when you are not inside a CRM form. https://msdn.microsoft.com/en-us/library/gg328541.aspx
<script src="ClientGlobalContext.js.aspx" type="text/javascript"></script>
The simplest thing for only getting this one value is using the parent to get values on the form:
window.parent.Xrm.Page.getAttribute("quotenumber").getValue();
Other options, pass values to your webresource: https://msdn.microsoft.com/en-us/library/gg327945.aspx
Or use the OData API: https://msdn.microsoft.com/en-us/library/gg334279.aspx
