SP.ListOperation.Selection ClassProvides methods for selecting lists or list items, in particular SP.ListOperation.Selection.getSelectedItems() methodGets the list items being selected
SP.ListOperation.Selection 类提供选择列表或列表项的方法，特别是SP.ListOperation.Selection.getSelectedItems() 方法获取被选择的列表项
Example 1: Get selected items
示例 1：获取所选项目
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!)
注意：方法 SP.ListOperation.Selection.getSelectedItems 返回键/值集合 > 包含被选择的列表项（不是 SP.ListItem 集合！）
Example 2. Get selected SP.ListItem collection
示例 2. 获取选定的 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());
});
