SharePoint – Creating a Rotating Image Banner using JavaScript
April 27, 2015
2 comments
In this post I will show you how easily we can create a Rotating Image banner in SharePoint 2013. (I saw the requirement from http://sharepoint.stackexchange.com/a/139738/34350)
Images are stored in an Images Library (Picture Library)
First you need to place anĀ img
tag into the Page. This is the tag which loads Images from Library and cycles images every 5 seconds.
<img id="imageRotator" >
Once this is added, you can use below JavaScript code
var arrayOfImageObjects = new Array(); var currentImageIndex = 0; function GetImagesAndRotate() { var url = "http://siteurl/_api/web/lists/getbytitle('ImageLibrary')/items?$expand=File" jQuery.ajax({ url: url, type: "GET", headers: { "X-HTTP-Method":"MERGE", "accept": "application/json;odata=verbose", "content-type": "application/json;odata=verbose", "X-RequestDigest": $("#__REQUESTDIGEST").val(), }, success: function(data){ var result = data.d.results; for(i=0;i<result.length;i++){ var image = result[i]; var imageObject = { }; imageObject.Name = image.File.Name; imageObject.Url = image.File.ServerRelativeUrl; imageObject.Width = image.File.ImageWidth; imageObject.Height = image.File.ImageHeight; arrayOfImageObjects.push(imageObject); } setTimeout(NextImage,5000); }, error: function(){ alert("request failed"); } }); } function NextImage(){ if(currentImageIndex < arrayOfImageObjects.length) { jQuery('#imageRotator').attr('src',arrayOfImageObjects[currentImageIndex].Url); currentImageIndex++; } else currentImageIndex = 0; setTimeout(NextImage,5000); }
Finally you can invoke this using
jQuery(document).ready(function(){ GetImagesAndRotate(); });

Here is a utility function which can give you the Job Schedule
string GetTimerJobStatus(string timerJobName) { string schedule = string.Empty; SPSecurity.RunWithElevatedPrivileges(() => { SPWebApplication webApp = SPContext.Current.CurrentWeb.WebApplication; foreach (SPJobDefinition job in webApp.JobDefinitions) { if (job.Name.Equals(timerJobName)) { schedule = job.Schedule.GetType().FullName; break; } } }); return schedule; }
