Mark list item as viewed/read in SharePoint 2013 - list

Question

When a user views an item in SharePoint list, I need to capture that it has been viewed and who viewed the item (in additional columns). Is there a way to do that?

Answer 1

I did this by adding a script editor web part and inserting this script in there:
<script type="text/javascript" src="/jquery-1.10.2.min.js"></script>
<script src="/jquery.SPServices-2013.02a.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () { ExecuteOrDelayUntilScriptLoaded(loadConstants, "sp.js"); });
function loadConstants() {
var userid= _spPageContextInfo.userId;
var requestUri = _spPageContextInfo.webAbsoluteUrl + "/_api/web/getuserbyid(" + userid + ")";
var requestHeaders = { "accept" : "application/json;odata=verbose" };
$.ajax({
url : requestUri,
contentType : "application/json;odata=verbose",
headers : requestHeaders,
success : onSuccess,
error : onError
});
function onSuccess(data, request){
var loginName = data.d.Title;
var docurl = document.URL;
var beginindex = docurl.indexOf('?ID=') + 4;
var endindex = docurl.indexOf('&Source=');
var itemid = docurl.substring(beginindex, endindex);
var ctx = new SP.ClientContext("your website url");
var oList = ctx.get_web().get_lists().getByTitle('your library name');
this.oListItem = oList.getItemById(itemid);
this.oListItem.set_item('Read', loginName + ' ' + getTodayDate());
this.oListItem.update();
ctx.executeQueryAsync(
Function.createDelegate(this, this.onQuerySucceeded),
Function.createDelegate(this, this.onQueryFailed)
);
}
function onError(error) {
alert("error");
}
function getTodayDate() {
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
if(dd<10){dd='0'+dd} if(mm<10){mm='0'+mm} today = mm+'/'+dd+'/'+yyyy;
return today;
}
}
</script>
