javascript - 使用客户端对象模型 (CSOM) 获取 Sharepoint 选定列表项

Question

任何人都可以通过在 Sharepoint 2010 中使用客户端对象模型 (CSOM) 为获取 Sharepoint 选定列表项建议好的站点或示例代码来帮助我。我需要使用 CSOM 打印这些选定的项目。请帮助我。提前致谢。

Answer 1

SP.ListOperation.Selection Class提供用于选择列表或列表项的方法，特别是 SP.ListOperation.Selection.getSelectedItems() method获取被选中的列表项

示例1:获取选中的item

function getSelectedItems()
{
    var context = SP.ClientContext.get_current();
    var selectedItems = SP.ListOperation.Selection.getSelectedItems(context);
    return selectedItems;
}

Note: Method SP.ListOperation.Selection.getSelectedItems returns the key/value collection > that contains the list items being selected (not SP.ListItem collection!)

例子2.获取选中的SP.ListItem集合

function getSelectedItems(OnSuccess,OnError)
{
    var context = SP.ClientContext.get_current();
    var listId = SP.ListOperation.Selection.getSelectedList(); //selected list Id
    var selectedItemIds = SP.ListOperation.Selection.getSelectedItems(context); //selected Items Ids

    var list = context.get_web().get_lists().getById(listId);
    var listItems = [];
    for (idx in selectedItemIds)
    {
        var item = list.getItemById(parseInt(selectedItemIds[idx].id));
        listItems.push(item);
        context.load(item);
    }
    context.executeQueryAsync(
       function() {
          OnSuccess(listItems);       
       },
       OnError
    ); 

}

//Usage
getSelectedItems(function(items){
    for (var i =0 ; i < items.length;i++)
    {
       console.log(items[i].get_item('Title'));  
    }  
},function(sender,args){
    console.log('An error occured: ' + args.get_message());
});
