In some cases you need to do something with the selected items in a list. You can access the items by using some simple JavaScript code:
function GetSelectedItems(){
var ctx = SP.ClientContext.get_current();
var items = SP.ListOperation.Selection.getSelectedItems(ctx);
var item;
for(item in items){
alert("selected item id: " + items[item].id));
}
}
You can use this code in a HTML Form WebPart or create a Ribbon button and call this function.
