MOSS通用类 通用方法整理

OM通用：

提升权限读取：

 

 

 

 

 

 

 

 

 

 

 

 

 

 

SPSecurity

 

 

.RunWithElevatedPrivileges(delegate

()

{

 

 

 

 

      SPWeb web = SPControl.GetContextWeb(context);

 

 

      using (SPSite elevSite = new SPSite(web.Site.ID))

      {

 

 

         using (SPWeb elevWeb = elevSite.OpenWeb(web.ID))

           {

 

 

               SPList list = elevWeb.Lists["ListName"];

 

 

               SPListItemCollection items = list.Items;

 

 

               if (items != null)

              {

 

 

                for (int i = 0; i < items.Count; i++)

                {

                    //....

                 }

              }

            }

       }

 

 

});

 

如果为权限读取：

SPList list = elevWeb.Lists["ListName"];

 

 

SPListItemCollection items = list.Items;

 

 

if (items != null)

{

 

 

      for (int i = 0; i < items.Count; i++)

       {

                    //....

        }

}

 

在js中Share Point web Service方法：只列出有用的几个类型的读取。

 

//-------------------------the following code is core source code , you can use it directly.---------

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

//Below is the core js source code.

 

 

 

function

;

 

 

/* List template IDs */

 

 

this.LIST_ID_DOCUMENT_LIBRARY = 101

// Document library

 

 

this.LIST_ID_USER_INFO = 112

// User Information list

 

 

this.LIST_ID_GENERIC = 100

// Generic list

使用方法示例：

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

function

 

 

searchIssueByID() {

 

 

var lists = new SPAPI_Lists(''

);

 

 

 

 

var items = lists.getListItems('Issues','','<Query><Where><Eq><FieldRef Name="ID"/><Value Type="Counter">' + issueId + '</Value></Eq></Where></Query>',

// query

 

 

'<ViewFields><FieldRef Name="Name"/></ViewFields>'

,

1,

 

// rowLimit

 

 

''

// queryOptions

);

 

 

if (items.status == 200)

{

 

 

     var rows = items.responseXML.getElementsByTagName('z:row');

 

 

}

);

 

 

return false

;
