Remove User Group Permission From SharePoint Site Using JSOM

In this article I will share a way to remove the user group permission from SharePoint using JavaScript object model.

Steps for implementation:

• Get Current Context.
• Get App web URL and Host Web URL from Query string parameter.
• Calling RemoveGroup method in document ready.
• Get web from app context site.
• Get RollAssignment from host web site.
• Then delete the object using principle ID (User Group ID)
• Finally group will be removed from SharePoint site as expected.

In your JavaScript file write the following code,

// Js code Starts here
'use strict';
//Get Current Context
var context = SP.ClientContext.get_current();
//Declaring the variables
varhostWebURL, appWebURL;
// this code runs when the DOM is ready and creates a context object which is needed to use the SharePoint object model
$(document).ready(function()

    {
    // Get App web URL and Host Web URL from Query string parameter
    hostWebURL = decodeURIComponent(manageQueryStringParameter('SPHostUrl'));
    appWebURL = decodeURIComponent(manageQueryStringParameter('SPAppWebUrl'));
    //Calling remove group method in document ready
    RemoveGroup();
});
functionRemoveGroup()
{
    varcWeb = appCtx.get_web();
    varroleAssignments = cWeb.get_roleAssignments();
    //552 is id of user group
    roleAssignments.getByPrincipalId("552").deleteObject();
    context.load(cWeb);
    context.executeQueryAsync(function()
    {
        alert("success");
    }, function(sender, args)
    {
        alert("Request failed to change the group name " + args.get_message());
    });
}

//method for read query string valuefunction manageQueryStringParameter(paramToRetrieve) {    var params = document.URL.split("?")[1].split("&");    var strParams = "";    for (var i = 0; i < params.length; i = i + 1) {        var singleParam = params[i].split("=");        if (singleParam[0] == paramToRetrieve) {            return singleParam[1];        }    }}
