var fieldSeparator = "|";
function FileUploadStart() {
document.getElementById("uploadedListFiles").innerHTML = "";
}
function FileUploaded(s, e) {
if(e.isValid) {
var linkFile = document.createElement("a");
var indexSeparator = e.callbackData.indexOf(fieldSeparator);
var fileName = e.callbackData.substring(0, indexSeparator);
var pictureUrl = e.callbackData.substring(indexSeparator + fieldSeparator.length);
var date = new Date();
var imgSrc = "UploadImages/" + pictureUrl + "?dx=" + date.getTime();
linkFile.innerHTML = fileName;
linkFile.setAttribute("href", imgSrc);
linkFile.setAttribute("target", "_blank");
var container = document.getElementById("uploadedListFiles");
container.appendChild(linkFile);
container.appendChild(document.createElement("br"));
}
