Uploading multiple documents into sharepoint list item with REST in sharepoint 2013 using content editor web part :

Question

hi ,
i am trying to upload multiple document files into sharepoint list item. I followed below link for implementaion.
http://techfindings-prem.blogspot.in/search/label/jquery.multifilejs
It was working for sharepoint hosted app.
 This complete code is written within content edito web part.
It was working when i was in root site collection with below change (hard coded the root level url) in code in "UploadFile" function.
var scriptbase = "http://servername" + "/_layouts/15/";
            console.log(' File size:' + bytes.length);
            $.getScript(scriptbase + "SP.RequestExecutor.js", function () {
                var createitem = new SP.RequestExecutor("http://servername");
                createitem.executeAsync({
                    url: "http://servername/sites/cpg/" + "/_api/web/lists/GetByTitle('SalesRecord')/items(" + attachmentitemid + ")/AttachmentFiles/add(FileName='"
+ fileName + "')",
                    method: "POST",
                    binaryStringRequestBody: true,
                    body: binary,
                    success: fsucc,
                    error: ferr,
                    state: "Update"
                function fsucc(data) {
                    //alert( data.statusText + "\n\n" + data.responseText);
                    console.log(data + ' uploaded successfully');
                    deferred.resolve(data);
                function ferr(data) {
                    //alert( data.statusText + "\n\n" + data.responseText);
                    console.log(fileName + "not uploaded error");
                    deferred.reject(data);
But the issue came in picture when i was working with the other site collection instead of root one. The url was like below.
"http://servername/sites/cpg/". This time i need to be there within "cpg" site collection. 
Now if i hard code the url as i did above my code gets break here while come to below line
 $.getScript(scriptbase + "SP.RequestExecutor.js", function () {
I am getting error when i used below code:
var scriptbase = "http://servername" + "/_layouts/15/";
 $.getScript(scriptbase + "SP.RequestExecutor.js", function () {
                var createitem = new SP.RequestExecutor("http://servername");
                createitem.executeAsync({
                    url: "http://servername/sites/cpg/" + "/_api/web/lists/GetByTitle('SalesRecord')/items(" + attachmentitemid + ")/AttachmentFiles/add(FileName='"
+ fileName + "')",
                    method: "POST",
                    binaryStringRequestBody: true,
                    body: binary,
                    success: fsucc,
                    error: ferr,
                    state: "Update"
                function fsucc(data) {
                    //alert( data.statusText + "\n\n" + data.responseText);
                    console.log(data + ' uploaded successfully');
                    deferred.resolve(data);
                function ferr(data) {
                    //alert( data.statusText + "\n\n" + data.responseText);
                    console.log(fileName + "not uploaded error");
                    deferred.reject(data);
Please hekp in this case. This complete code is written within content edito web part.

Hi,
According to your post, my understanding is that you have an issue about upload multiple documents files into library vai REST API.
As you have said, you have used the hard code url in your code.
How about use the _spPageContextInfo.webAbsoluteUrl method to get the url?
I have used this method to get the url, then use the code in the article you have pasted within a content editor web part to upload the files.
You can replace the hard code url with the _spPageContextInfo.webAbsoluteUrl method, then check whether it works.
Thanks,
Jason
