Preface: In the functional more powerful background management website is in various angles to consider many has the application authority management function. Take the company internal management system as an example, the administrator according to different employees in different departments to give them different permissions, or according to subordinate relationship to achieve "pyramid" management. The contents of this article are not in the truth.
Body:
The following effect diagram makes a user have the appropriate permissions to distinguish between storage using a CheckBox state.
(i) Storage
Here the permission function (category) Name and Permissions module (specific) name are manually entered the database, can not be deleted and checked. This example takes a permission module as the most basic element and whether the permission is represented by 1 or 0, and then stores all of the current user's permission links into a binary string in the database. Such as example code 1.1
(ii) reads like example code 1.2
(c) The front desk code is as follows
Copy Code code as follows:
Use JS to add commas and vertical bars, passing values through hidden
<script language= "javascript" type= "Text/javascript" >
function Getcheck () {
var inputs = document.getElementById ("Cbpanel");
var chks = inputs.getelementsbytagname ("input");
var str = "";
for (var i = 0; i < chks.length; i++) {
if (Chks[i].type = = ' checkbox ') {
STR + + Chks[i].value + "," + chks[i].checked + "|";
}
}
document.getElementById ("Hidden1"). Value = str;
}
<script>
<body>
<div id= "Cbpanel" > <asp:literal id= "literalrole" runat= "Server" ></asp:Literal>
<input id= "Hidden1" runat= "Server" type= "hidden"/></div>
