I have already covered a great script by Paul Grenier about how to prepopulate fields in SharePoint forms with values from the url.
Christian Dehaeseleer from U2U told me this morning about another codeplex project from Paul Grenier that is called the “Form Field Assistant”.
Practically, it does about the same thing, but it looks more complete. Very handy is that it is a separate library that you can load when you want to.There is a problem with the loading though, if you are going to use this invoke the library via:
function customLoadEvent() { $.spff({ lock: true }); } _spBodyOnLoadFunctionNames.push("customLoadEvent");
