Question

我在尝试由用户获取列表过滤器上的值时遇到了一些问题。现在我得到一个view.getItems不是函数”，当我将它们更改为List.getItems('');时，它可以工作，但不能过滤。

function sharePointReady() {
    var targetClientContext;
    var List;
    var view;

    targetClientContext = new SP.ClientContext.get_current();
    List                = targetClientContext.get_web().get_lists().getByTitle('My Recognitions');
    view                = List.get_views().getByTitle('CurrentUser');
    this.collList       = view.getItems("");

    //Get the list view and load it to client context and execute the batch  
    targetClientContext.load(collList);
    targetClientContext.executeQueryAsync(onRequestSucceeded, onRequestFailed);
}

var value = 0;
var counter = 0;

for (var i = 0; i < 1; i++) {
    function onRequestSucceeded() {
        var listItemEnum = collList.getEnumerator();
        while (listItemEnum.moveNext()) {
            view = listItemEnum.get_current();
            console.log(view.get_item('ID'));
            console.log('Load ' + ++counter);
            value = view.get_item('Value');
            console.log(value);    
        }
        console.log('');
        console.log('Tu puntos son: ' + counter);
        document.getElementById("try").innerHTML = counter + ' Points';
    }
}

function onRequestFailed(sender, args) {
    alert('Error: ' + args.get_message() + '\n' + args.get_stackTrace());
}

预先感谢

要获得基于现有视图的列表项的视图，可以通过view.get_viewQuery()方法获取视图的基础CAML查询XML。

然后，您可以将该字符串输入新的SP.CamlQuery对象的View XML中，然后将其传递给list.getItems()以获取结果。

 var clientContext = new SP.ClientContext();
 var list = clientContext.get_web().get_lists().getByTitle("My Recognitions");
 var view = list.get_views().getByTitle("CurrentUser");
 clientContext.load(view);
 clientContext.executeQueryAsync(function(){
      var query = view.get_viewQuery();
      var camlQuery = new SP.CamlQuery();
      camlQuery.set_viewXml(query);
      var items = list.getItems(camlQuery);
      clientContext.load(items);
      clientContext.executeQueryAsync(
           function(){
                 var itemEnumerator = items.getEnumerator();
                 var counter = 0;
                 while(itemEnumerator.moveNext()){
                     var item = itemEnumerator.get_current();
                     console.log(item.get_item("ID"));
                     console.log('Load ' + ++counter);
                     console.log(item.get_item("Value"));
                }
                console.log('Tu puntos son: ' + counter);
                document.getElementById("try").innerHTML = counter + ' Points';
           },
           onRequestFailed
      );
 },onRequestFailed);

 function onRequestFailed(sender, args) {
     alert('Error: ' + args.get_message() + '\n' + args.get_stackTrace());
 }

请注意，这需要两个异步调用：一个获取视图XML，另一个实际获取项。

以下代码供您参考。

<script type="text/javascript">
ExecuteOrDelayUntilScriptLoaded(sharePointReady, "sp.js");

function sharePointReady(){
    getItemsFromView("My Recognitions", "CurrentUser",
        function(items){
             for(var i = 0; i < items.get_count(); i++){
                 var item = items.get_item(i);
                 console.log(item.get_item('Title'));
             }
         },
         function(sender,args){ 
             console.log(args.get_message())
         }
    );
}

function getItemsFromView(listTitle, viewTitle,success,error){
    var ctx = new SP.ClientContext();
    var list = ctx.get_web().get_lists().getByTitle(listTitle);
    var view = list.get_views().getByTitle(viewTitle);
    ctx.load(view,'ViewQuery');
    ctx.executeQueryAsync(
        function() {
            var viewQry = "<View><Query>" + view.get_viewQuery() + "</Query></View>";
            getItems(listTitle,viewQry,success,error);
        },
        error);
}

function getItems(listTitle, queryText,success,error) {
    var ctx = new SP.ClientContext();
    var list = ctx.get_web().get_lists().getByTitle(listTitle);
    var query = new SP.CamlQuery();
    query.set_viewXml(queryText);
    var items = list.getItems(query);
    ctx.load(items);
    ctx.executeQueryAsync(
        function() {
            success(items);
        },
        error
   );
}
</script>

在SharePoint 2013中，如果您只想获取当前用户创建的列表项，则可以将REST API与$ filter配合使用来实现。

<script src="http://code.jquery.com/jquery-1.11.3.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
    var siteURL = _spPageContextInfo.webAbsoluteUrl;
    var listname = "My Recognitions";
    var currentUserId=_spPageContextInfo.userId
    var url = siteURL + "/_api/web/lists/getbytitle('" + listname + "')/items?$filter=Author/Id eq "+currentUserId;
    $.ajax({
        url: url,
        method: "GET",
        headers: { "Accept": "application/json; odata=verbose" },
        success: function (data) {       
            var items = data.d.results;
            $.each(items,function(index,item){
                console.log("Title:"+item.Title);
            });
        },
        error: function (error) {
        console.log(JSON.stringify(error));
        }
    });
});
</script>
