How to determine user permissions on the custom page of SharePointDesigner

Sometimes it is necessary to determine the user's permission points in customized development by using pointdesigner, and determine the user's identity based on different permission points to provide different services, there is a default SPSecurityTrimmedControl control that identifies permissions. This control is especially useful if you want to have different Behavior based on different permissions when customizing the site using pointdesigner.

In the following example, different values of the script variables are set based on different permissions. Note that the permission string is related, that is, the permissions are superimposed.

<script>     var msg = 0;     var canBook = 0; </script> <Sharepoint:SPSecurityTrimmedControl runat="server" PermissionsString="AddAndCustomizePages, ManageLists">     <script>         canBook = 1;     </script></Sharepoint:SPSecurityTrimmedControl>
