我有 3 个图书馆，我想显示图书馆项目名称。如果我只想显示一个图书馆的项目，一切都很好，但如果我正在寻找两个或更多图书馆的项目，它仍然只显示一个图书馆的项目。我的代码有什么问题？

    <p id="AInfo">library A Items</p>
    <p id="BInfo">library B Items</p>
    <p id="CInfo">library C Items</p>

    <script type="text/javascript">

        jQuery(document).ready(function(){ExecuteOrDelayUntilScriptLoaded(fill, "sp.js"); });

        var siteUrl = '/Example/test/';
        liblist = new Array("A", "B", "C"); //list of the libraries
        var i=0;
        var lib;

        function fill(){
            while (i<3){
                lib = liblist[i];
                alert(lib);
                retrieveListItemsInclude();
                i++;
            }
        }


        function retrieveListItemsInclude() {


            var clientContext = new SP.ClientContext(siteUrl);
            var oList = clientContext.get_web().get_lists().getByTitle(lib);

            var camlQuery = new SP.CamlQuery();
            camlQuery.set_viewXml('<View><RowLimit>100</RowLimit></View>');
            this.collListItem = oList.getItems(camlQuery);

            clientContext.load(collListItem, 'Include(Id, DisplayName, HasUniqueRoleAssignments)');

            clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
        }


            function onQuerySucceeded(sender, args) {
                var listItemInfo = '';
                var listItemEnumerator = collListItem.getEnumerator();            

                while (listItemEnumerator.moveNext()) {
                    var oListItem = listItemEnumerator.get_current();
                    listItemInfo += oListItem.get_displayName()+ '<br>';
                }

                var x = listItemInfo.toString();
                document.getElementById(lib+"Info").innerHTML = x;
        }


        function onQueryFailed(sender, args) {

            var x = 'Request failed. ' + args.get_message() + '\n' + args.get_stackTrace();
            document.getElementById(lib+"Info").innerHTML = x;  
        }

    </script>

您可以创建 .ASHX Web 服务并将其部署到 SharePoint Server。然后，您可以使用 REST 和 JSON 从 JavaScript 的 HttpRequest 查询它。

我认为您需要等待第一个请求完成，然后再执行第二个请求。类似的东西（但代码很脏，因为你应该避免使用全局变量......）

<p id="AInfo">library A Items</p>
<p id="BInfo">library B Items</p>
<p id="CInfo">library C Items</p>

<script type="text/javascript">

    jQuery(document).ready(function(){ExecuteOrDelayUntilScriptLoaded(fill, "sp.js"); });

    var siteUrl = '/Example/test/';
    liblist = new Array("A", "B", "C"); //list of the libraries
    var i=0;
    var lib = liblist[i];
    retrieveListItemsInclude();

    function retrieveListItemsInclude() {


        var clientContext = new SP.ClientContext(siteUrl);
        var oList = clientContext.get_web().get_lists().getByTitle(lib);

        var camlQuery = new SP.CamlQuery();
        camlQuery.set_viewXml('<View><RowLimit>100</RowLimit></View>');
        this.collListItem = oList.getItems(camlQuery);

        clientContext.load(collListItem, 'Include(Id, DisplayName, HasUniqueRoleAssignments)');

        clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
    }


        function onQuerySucceeded(sender, args) {
            var listItemInfo = '';
            var listItemEnumerator = collListItem.getEnumerator();            

            while (listItemEnumerator.moveNext()) {
                var oListItem = listItemEnumerator.get_current();
                listItemInfo += oListItem.get_displayName()+ '<br>';
            }

            var x = listItemInfo.toString();
            document.getElementById(lib+"Info").innerHTML = x;
            if (++i<3) {
              lib = liblist[i];
              retrieveListItemsInclude()
            }
    }


    function onQueryFailed(sender, args) {

        var x = 'Request failed. ' + args.get_message() + '\n' + args.get_stackTrace();
        document.getElementById(lib+"Info").innerHTML = x;  
    }

</script>
