在Ribbon上添加一个按钮可以发送当前Item的链接

• 新建一个页面，添加Content Edit Webpart，加入如下代码

<script type="text/javascript">
function func(){
var url=getQueryStringByName("url");
var body="xxx/Lists/test/DispForm.aspx?id="+url;
document.getElementById("sendmail").href="mailto:?subject=title&body="+body;
document.getElementById("sendmail").click();
window.frameElement.cancelPopUp();
}

function getQueryStringByName(name){
     var result = location.search.match(new RegExp("[?&]" + name+ "=([^&]+)","i"));
     if(result == null || result.length < 1){
         return "";
     }
     return result[1];
}
window.onload=func;
</script>
<a href="" id="sendmail">Click</a>

• 用Designer添加相应的Ribbon

　　　Ribbon Location：Ribbon.ListForm.Display.Manage.Controls._children

　　　Navigate to URL：xxx/send.aspx?url={ItemId}
