[jQuery] $.post is not a function

[jQuery] $.post is not a function


I have jquery.js loaded (visible in firebug)
I have editor.js loaded (visible in firebug) after jquery.js
Here is the code:
function (){
         this.content = this.getContent();
     $.post("updateStandardsCell",
         {key: formatPOST(this.sid), content:
formatPOST(this.content)},
             function(data) {
                 Editor.instance.refreshPage(data);
             }
     );
}
Code almost precisely like this in a different view works just fine.
This code responses to a Save button, but when clicked, I get the
error message in firebug.
Does that raise any recollections? Did I miss something?
Thanks
Jack
