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
SPAPI_Lists() {
this.core = new
SPAPI_Core();
this.serviceUrl = baseUrl + '/_vti_bin/lists.asmx'

/* 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

this.getListItems = function

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
;
以上是在应用开发中常用到的。随时补充。
