I have a SharePoint site which has the following permission levels (Navigate to the SharePoint site. Click on Site Actions and then click on Site Settings. Click on Site Permissions in the Users and Permissions section. In the ribbon interface, click on Permission Levels).

Step 1 : Navigate to the SharePoint site (I have a site page created in my site where I am going to add the content editor web part). Step 2 : Go to Site Actions, click on Edit Page Step 3 : Click on the Insert tab in the ribbon interface and then click on Web Part button. Step 4 : Select Media and Content in the Categories section and then click on Content Editor. Step 5 : Click on Add Step 6 : The Content Editor web part will be added to the site page.

Step 11 : The HTML source window will pop up. Step 12 : Copy and paste the following script.

<script language="ecmascript" type="text/ecmascript"> var roleDefinitionCollection; var roleDefinition;

function permissionLevel() { var clientContext = new SP.ClientContext.get_current(); if (clientContext != undefined && clientContext != null) { var web = clientContext.get_web(); this.roleDefinitionCollection = web.get_roleDefinitions(); this.roleDefinition = roleDefinitionCollection.getByName("Design"); clientContext.load(roleDefinition); clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed)); } } function onQuerySucceeded()  {  alert("Name: " + roleDefinition.get_name() + "\n" + "Id: " + roleDefinition.get_id() + "\n" +"Description: " + roleDefinition.get_description()); } function onQueryFailed(sender, args) { alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace()); } </script> <input id="btnPermissionLevels" onclick="permissionLevel()" type="button" value="Get Permission Level" />

Step 13 : Click on OK.
