因此,我正在为 SharePoint 创建显示模板,但无法获取上下文,因为我需要它来访问不同的列表及其项目等。我在搜索时看到的一种方法是:

var context = Srch.ScriptApplicationManager.get_clientRuntimeContext();

问题是我不知道如何访问这个对象的内容。每次我收到上下文未定义或为空的错误,或者我打印出它的文字函数。在其他程序(不是显示模板)中,我只会使用:

var context = new ClientContext(); 

或者

var context = new SP.ClientContext();

或一些变体,但在这种情况下,我找不到任何使用第一个的文档或示例。只是(大部分)博客说您可以使用它来获取上下文。

我的代码现在大部分都被注释掉了。我现在只是想弄清楚这种情况。提前致谢。

这是整个(项目显示模板)文件:

Srch.ScriptApplicationManager.get_clientRuntimeContext函数返回代表的SP.ClientRuntimeContext对象the runtime context for accessing data from and invoking methods on remote objects

以下示例演示如何在显示模板中检索列表项和打印页面 url:

var context = Srch.ScriptApplicationManager.get_clientRuntimeContext();

var reqCtx = SP.RequestContext.getCurrent(context);
var web = reqCtx.get_web();

var pagesListId = SP.PageContextInfo.get_pageListId(); //Pages List Id
var list = web.get_lists().getById(pagesListId);
var items = list.getItems(SP.CamlQuery.createAllItemsQuery());
context.load(items);
context.executeQueryAsync(
   function(){
       items.get_data().forEach(function(item){
           console.log(item.get_item('FileRef')); 
       });
   },
   function(sender,args){
      console.log(args.get_message()); 
   });

为确保加载SP.ClientRuntimeContext对象,您可以使用SP.SOD.executeFuncfunction,例如:

SP.SOD.executeFunc('SP.js', 'SP.ClientContext', function() {

    var context = Srch.ScriptApplicationManager.get_clientRuntimeContext();

    //the remaining code goes here...


});   

选项 2. 使用SP.ClientContext

以下示例演示了如何SP.ClientContext class在显示模板中使用:

 SP.SOD.executeFunc('SP.js', 'SP.ClientContext', function() {

        var context = SP.ClientContext.get_current();
        var web = context.get_web();

        var pagesListId = SP.PageContextInfo.get_pageListId();
        var list = web.get_lists().getById(pagesListId);
        var items = list.getItems(SP.CamlQuery.createAllItemsQuery());
        context.load(items);

        context.executeQueryAsync(
           function(){
               items.get_data().forEach(function(item){
                   console.log(item.get_item('FileRef')); 
               });
           },
        function(sender,args){
          console.log(args.get_message()); 
        });
 });
