Changing Master Page Through CSOM in SharePoint 2013

SharePoint 2013 - Changing Master Page through CSOM

This article explains how to change a Master Page using JavaScript CSOM. In many cases, project requirements require us to use client scripting rather than server-side deployment. In one of my assignments, I was asked to change a MasterPage without involving the Farm administrator’s efforts and CSOM comes to the rescue. The following is the code snippet that does the job for us.

function MastePageChange() {

var clientcontext;

var cweb;

var customMasterURL = '/_catalogs/masterpage/NewMasterPage';

clientcontext = new SP.ClientContext.get_current();

cweb = clientcontext.get_web();

cweb.set_customMasterUrl(masterPageUrl);

cweb.set_masterUrl(masterPageUrl);

cweb.update();

clientcontext.executeQueryAsync(function () {

alert("Master Page has been changed successfully \n" + customMasterURL);

}, function (sender, args) {

alert("Error: " + args.get_message());

});

}

MastePageChange();

</script>
