SharePoint 2010 Wiki Template Script Issue - sharepoint-2010

Question

I'm looking for a way to give my SharePoint users a way to create new wiki pages from an existing template. In the process of researching I found a great walkthrough that seems to fit the need (http://www.mssharepointtips.com/tip.asp?id=1072&page=2), but I'm having trouble getting it to work. The problem seems to lie in the assignment of a path to PATHTOWIKI-- if I use "/Weekly Update Wiki", the script returns an error of "There is no Web named '/Weekly Update Wiki'." If I use "Weekly Update Wiki" without the forward slash, I instead get an error of "There is no Web named '/sites/[parentSite]/[childSite]/Weekly Update Wiki/Weekly Update Wiki'."
Any ideas about what I'm not understanding here?
function myCreateProject() {
// Configure these for your environment
// include no slashes in paths
var PATHTOWIKI = "Weekly Update Wiki";
var PATHTOPAGES = "Pages";
// file name only for template page, no extension
var TEMPLATEFILENAME = "Template";
var myPathToWiki = encodeURIComponent(PATHTOWIKI);
var myPathToPages = PATHTOPAGES + "%2f";
var myTemplateFileName = encodeURIComponent(TEMPLATEFILENAME) + "%2easpx";
var EnteredProject = document.getElementById("NewProjName");
var myNewName = EnteredProject.value;
if(myNewName == "") {
alert('Please enter a name for the new project page');
} else {
myNewName = encodeURIComponent(myNewName) + "%2easpx"
$.ajax({
url: PATHTOWIKI + "/_vti_bin/_vti_aut/author.dll",
data: ( "method=move+document%3a14%2e0%2e0%2e4730&service%5fname="
+ myPathToWiki +
"&oldUrl=" + myPathToPages + myTemplateFileName +
"&newUrl=" + myPathToPages + myNewName +
"&url%5flist=%5b%5d&rename%5foption=nochangeall&put%5foption=edit&docopy=true"
),
success: function(data) {
var rpcmsg1 = getMessage(data, "message=", "<p>");
$("#myInfo").append("<br />" + rpcmsg1);
if(rpcmsg1.indexOf("successfully") < 0) {
// get error info
var rpcmsg2 = getMessage(data, "msg=", "<li>");
$("#myInfo").append("<br />" + rpcmsg2 + "<br />");
} else {
$("#myInfo").append("<br />Go to new page<br />");
}
},
type: "POST",
beforeSend: function(XMLHttpRequest) {
XMLHttpRequest.setRequestHeader("X-Vermeer-Content-Type",
"application/x-www-form-urlencoded");
}
});
}
}
Update: I figured out what needed to happen in my case. Since I couldn't get a grasp on the relative approach, I just went with the absolute path for PATHTOWIKI and slightly modified the append in the ajax call.
PATHTOWIKI:
var PATHTOWIKI = "https://[domain]/sites/[parentSite]/[childSite]";
append:
$("#myInfo").append("<br />Go to new page<br />");
The change in the latter line of code is subtle; since I used an absolute path in PATHTOWIKI, I just removed the leading forward slash in the anchor tag, so that <a href=\"/" became <a href=\"". This renders the script slightly less portable, but since it's a one-off effort I'll stick with this unless anything comes along to expand the scope.
