If I have a link to a document (which could be on another site than the current site), how can I extract a web relative url to the document from the url of the document? I am not sure how to do it because how would you differentiate a list name from another subsite name.

Does anyone know?



Here's a slightly modified version of the code I created in an older question - this should help you achieve your task.

Reference: JSOM - get listitem by file URL

function getFileProperties(url, fileUrl) {
    var ctx = new SP.ClientContext(url); //get context
    var siteCollection = ctx.get_site(); //try get site to check if context is valid
        function () {
            // context is valid - proceed 
            var relUrl = fileUrl.replace(_spPageContextInfo.siteAbsoluteUrl, '');  //convert to relative url
            alert('webrelativeurl is -- ' + relUrl);
            var file = ctx.get_web().getFileByServerRelativeUrl(relUrl);   //get file
            ctx.load(file, 'ListItemAllFields');

                function () {
                    var listItem = file.get_listItemAllFields(); 
                    var comment = listItem.get_fieldValues()._Comments; 
                    var copyright = listItem.get_fieldValues().wic_System_Copyright;

                    $("#Description input").val(comment); //apply
                    $("#Copyright input").val(copyright);

                function (sender, args) {
                    console.log(args.get_message()); //errorhandling
        function (sender, args) {
            //context is invalid - shrink url and try again
            if (url.indexOf("/") !== -1) {
                url = url.substr(0, url.lastIndexOf("/"));
                getFileProperties(url, fileUrl); //recursive call
            //else - the url is not compatible

var imageUrl = 'http://yourfullimageurl/sites/sc/weba/webb/images/imagea.jpg'

//get image file properties
getFileProperties(imageUrl, imageUrl);
