SharePoint ECB Customization-Add menu to 'sendTo'

在DIN Project中,我们有这样一个需求:在DIN Library ECB默认的SendTo 的子Menu中加入我们自己指定的Menu.
 重点注意的是:
1.加入的位置
2.只针对DIN Library 加入.
思路:找到_layouts/1033/Core.js下面的AddSendSubMenu方法,通过在Delegate Control中Override Core.js的方法来实现我们需求。
  Solution:
 1.创建Delegate Control,通过feature来部署delegate control. 2.在delegate control中 ovrride Core.js AddSendSubMenu.
关键代码如下(注意注释..):
$(function() {
 var spAddSendSubMenu = AddSendSubMenu;
AddSendSubMenu = function(m, ctx) {
 //通过ctx的listTemplate 属性来判断是否是DIN Library.
//如果是,Copy core.js中的AddSendSubMenu函数体,修改,添加我们的需求。
 //如果不是,则执行Core.js 默认的AddSendSubMenu
             if (ctx.listTemplate == '100502') {
                strDisplayText = L_Send_Text;
                var currentItemUrl = GetAttributeFromItemTable(itemTable, "Url", "ServerUrl");
                var currentItemEscapedFileUrl;
                var currentItenUnescapedUrl;
                var strExtension;
                if (currentItemFileUrl != null) {
                    currentItenUnescapedUrl = unescapeProperly(currentItemFileUrl);
                    currentItemEscapedFileUrl = escapeProperly(currentItenUnescapedUrl);
                    strExtension = SzExtension(currentItenUnescapedUrl);
                    if (strExtension != null && strExtension != "")
                        strExtension = strExtension.toLowerCase();
                }
