在SharePoint 2013中创建并使用Callout

在SharePoint 2013中引入了一个新的客户端框架：Callouts，即当用户点击或者悬浮鼠标的时候，弹出窗口，例如：

或者：

第一个弹出窗是解释说明，第二个包含一些后续的操作。

首先看如何实现第一个解释说明callout。SharePoint提供了一个对象CalloutManager来创建自己的callout，这个对象是在C:Program FilesCommon Filesmicrosoft sharedWeb Server Extensions15TEMPLATELAYOUTSCallout.js文件中定义的，使用方法很简单：

首先要定义一个div元素：

<div id="CalloutDiv" style="100px">Callout</div>

<div id="CalloutDiv" style="100px">Callout</div>

如果想和SharePoint一样也有个感叹号的标志，可以在div中嵌入一个span：

<div id="CalloutDiv" style="100px">
    Callout <span id="ms-pageDescriptionImage"> </span>
</div>

<div id="CalloutDiv" style="100px">
    Callout <span id="ms-pageDescriptionImage"> </span>
</div>

然后就可以使用CalloutManager创建callout：

var calloutDiv = document.getElementById('CalloutDiv');   //获取callout div

var calloutOptions = new CalloutOptions();      //创建一个CalloutOption，用来指定一些参数
calloutOptions.ID = 'MyCallout';                //指定callout的ID
calloutOptions.launchPoint = calloutDiv;        //绑定callout到CalloutDiv上
calloutOptions.content = 'This is Callout Test Description';    //指定callout的内容
calloutOptions.title = 'This is Callout Test Title';            //指定callout的标题
var callout = CalloutManager.createNew(calloutOptions);         //创建callout

var calloutDiv = document.getElementById('CalloutDiv');   //获取callout div

var calloutOptions = new CalloutOptions();      //创建一个CalloutOption，用来指定一些参数
calloutOptions.ID = 'MyCallout';                //指定callout的ID
calloutOptions.launchPoint = calloutDiv;        //绑定callout到CalloutDiv上
calloutOptions.content = 'This is Callout Test Description';    //指定callout的内容
calloutOptions.title = 'This is Callout Test Title';            //指定callout的标题
var callout = CalloutManager.createNew(calloutOptions);         //创建callout

以下是在Application Page中使用CalloutManager的例子：

<asp:Content ID="PageHead" ContentPlaceHolderID="PlaceHolderAdditionalPageHead" runat="server">
    <script type="text/javascript">
        SP.SOD.executeFunc('callout.js', 'CreateMyCallOut', function () {
            var calloutElement = document.getElementById('CalloutDiv');

            var calloutOptions = new CalloutOptions();
            calloutOptions.ID = 'MyCallout';
            calloutOptions.launchPoint = calloutElement;
            calloutOptions.content = 'This is Callout Test Description';
            calloutOptions.title = 'This is Callout Test Title';
            var callout = CalloutManager.createNew(calloutOptions);
        });
    </script>
</asp:Content>

<asp:Content ID="Main" ContentPlaceHolderID="PlaceHolderMain" runat="server">
    <div id="CalloutDiv" style="100px">Callout  <span id="ms-pageDescriptionImage"> </span></div>
</asp:Content>

<asp:Content ID="PageHead" ContentPlaceHolderID="PlaceHolderAdditionalPageHead" runat="server">
    <script type="text/javascript">
        SP.SOD.executeFunc('callout.js', 'CreateMyCallOut', function () {
            var calloutElement = document.getElementById('CalloutDiv');

            var calloutOptions = new CalloutOptions();
            calloutOptions.ID = 'MyCallout';
            calloutOptions.launchPoint = calloutElement;
            calloutOptions.content = 'This is Callout Test Description';
            calloutOptions.title = 'This is Callout Test Title';
            var callout = CalloutManager.createNew(calloutOptions);
        });
    </script>
</asp:Content>

<asp:Content ID="Main" ContentPlaceHolderID="PlaceHolderMain" runat="server">
    <div id="CalloutDiv" style="100px">Callout  <span id="ms-pageDescriptionImage"> </span></div>
</asp:Content>

注意需要使用SP.SOD.executeFunc方法，确保callout.js在执行代码之前加载。

再看如何实现第二种带有操作的callout。方法也很简单，首次构造一个CalloutActionOptions，指定操作的名字和点击事件，然后使用CalloutActionOptions创建一个CalloutAction，并将其添加到之前创建的callout对象之上，具体代码如下：

var calloutAction = new CalloutActionOptions();
           calloutAction.text = 'Click here';
           calloutAction.onClickCallback = function(event, action)
           {
               alert("This is Callout event1");
           };

           var action = new CalloutAction(calloutAction);
           callout.addAction(action);

 var calloutAction = new CalloutActionOptions();
            calloutAction.text = 'Click here';
            calloutAction.onClickCallback = function(event, action)
            {
                alert("This is Callout event1");
            };

            var action = new CalloutAction(calloutAction);
            callout.addAction(action);

运行之后的结果：

点击CLICK HERE就会弹出alert：
