在Sharepoint 2013中，使用JS判断当前用户是否在某个组里面

使用Sharepoint客户端对象模型，判断当前用户是否在某个组里面。

在View 和 Edit List Item的时候使用，使用户编辑修改List Item的时候有权限的区分。

在Edit 页面加入Content Edit Webpart，引用下面HTML文件。

<script language="javascript">

$(document).ready(function(){
    $('#DeltaPlaceHolderMain').attr('style','display:none')
});

function IsCurrentUserMemberOfGroup(groupName, OnComplete) {
        var currentContext = new SP.ClientContext.get_current();
        var currentWeb = currentContext.get_web();
        var currentUser = currentContext.get_web().get_currentUser();
        currentContext.load(currentUser);
        var allGroups = currentWeb.get_siteGroups();
        currentContext.load(allGroups);
        var group = allGroups.getByName(groupName);
        currentContext.load(group);
        var groupUsers = group.get_users();
        currentContext.load(groupUsers);
        currentContext.executeQueryAsync(OnSuccess,OnFailure);
        function OnSuccess(sender, args) {
            var userInGroup = false;
            var groupUserEnumerator = groupUsers.getEnumerator();
