本文介绍SharePoint 2013(其实也适用于2010,支持JavaScript OM) 中使用嵌入JavaScript方式实现一个垂直滚动列表:
当鼠标进入Item时停止滚动,当鼠标点击对应的Item时,显示对应的Item内容:
实现的大概思路是使用一段较短的JavaScript代码嵌入SharePoint页面,这个JavaScrip片段(可设置相关参数,如列表名,过滤条件等)调用另一个较大的JavaScript文件VerticalScrollingWebPart.js(存储到SharePoint 的SiteAssets/JavaScript中), VerticalScrollingWebPart.js 文件负责使用JavaScript OM 查询后台列表,并根据参数画出一个滚动列表:
嵌入的JavaScript 代码:
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.9.0.min.js"></script> <script type="text/javascript" src="/SiteAssets/Javascript/VerticalScrollingWebPart.js"></script> <script type="text/javascript"> init_fillScrollableDiv({'web':'', 'listBaseUrl': 'http://MossHost/Lists/ReadMarkList/DispForm.aspx', 'listName': 'ReadMarkList', 'viewFields':['Title','Body'], 'Filter':'<Where> <Or> <IsNull> <FieldRef Name=\"Expires\" /> </IsNull> <Geq> <FieldRef Name=\"Expires\"></FieldRef> <Value Type=\"DateTime\"> <Today></Today> </Value> </Geq> </Or> </Where>', 'viewFieldsStyle':['font-weight:bold','padding:0 0 0 5'], 'divID':'myScrollableDiv', 'divHeight':'250px', 'divWidth':'500px', 'speed':4, 'linkBack':true}); </script>
主要参数说明:
1. web,如果取子站点的列表需要填
2. listBaseUrl, 显示list item的地址
3. listName,要读取的list 名称
4.viewFields, 要显示的字段
5.Filter 过滤条件(CAML结构的 Where 子句)
VerticalScrollingWebPart.js 代码:
/* A vertical scrolling web part for SharePoint 2013 */ function init_fillScrollableDiv(obj) { // Build the div var myDivBuffer = []; myDivBuffer.push("<div style='vertical-align:top;position:relative;overflow:hidden;cursor:default;height:" + obj.divHeight + ";width:" + obj.divWidth + "'>"); myDivBuffer.push("<div id='" + obj.divID + "' style='position:relative'></div>"); myDivBuffer.push("</div>"); myDivContainer = myDivBuffer.join(''); document.write(myDivContainer); $(document).ready(function () { // fillScrollableDiv(obj) ExecuteOrDelayUntilScriptLoaded(function () { queryItemsByViewName(obj); }, "sp.js"); //queryItemsByViewName(obj); }); } function fillScrollableDiv(info, items) { info.animBegin = 0; info.animPart = 0; if (items.length == -1) alert("An error occured - check the parameters \"listBaseUrl\", \"web\"......"); var finalBuffer = []; var path = info.listBaseUrl; var res = new Object(); res.items = items; $.each(res.items, function (i, item) { var partBuffer = []; $.each(info.viewFields, function (idx, fin) { var style = ''; var thisVal = (item[fin] == null) ? '' : item[fin]; if (thisVal.indexOf(';#') > -1) { thisVal = thisVal.substring(thisVal.indexOf(';#') + 2); } if (info.viewFieldsStyle[idx] != undefined) { style = " style='" + info.viewFieldsStyle[idx] + "'"; } partBuffer.push("<tr><td" + style + ">" + thisVal + "</td></tr>"); }); finalBuffer.push("<hr style='height:1px;color:black' />"); if (info.linkBack) { finalBuffer.push("<table title='Go to item' style='cursor:pointer' &quo
