get the selected items in a sharepoint list using javascript

Question

In my SharePoint 2013 list , i am trying to get the ids of selected items using javascript . I used below script in content editor web part :

by using this i am able to get the ids . but i have two problems:

1. the result i am getting is like - 1,1,0 or 1,2,0 if i select items.

2. I need to get the collection of selected.

3. I need to select item by clicking on checkbox which is not working although i have put up input type as checkbox id.

Answer 1

Please mark Sam's answer as the correct one.

Note that on the current ListView page the global ctx is already available,
so a call to get_current() is not required

SP.ListOperations take the default ctx when none is specified.

var selected=SP.ListOperation.Selection.getSelectedItems();

Gets you an Object array

var selectedStr = selected.map(function(item){ // loop all Objects
    return item.id;                            // return the ID
}).join(',');                                  // concatenate to one string 
console.log('selected IDs:',selectedStr);

Answer 2

Please use below code.

function clickMethod() {

var ctx = SP.ClientContext.get_current();

var items = SP.ListOperation.Selection.getSelectedItems(ctx);

var mySeletedItems = '';

 var i;

 for (i in items)
 {
      mySeletedItems += '|' + items[i].id;
 }
alert (mySeletedItems);

}

Hope it will works for you.

Answer 3

If you want to get the selected items from the list view, you can use the SP.ListOperation to get the selected items using Javascript. Refer this

Answer 4

Both code example answers are kinda wrong.

Correct usage

var items = SP.ListOperation.Selection.getSelectedItems() // parameter won't do things

What's wrong with the current answers

-> Samir Khimani

You can't provide a context since the function does not take parameters.

-> Danny '365CSI' Engelman

While it is true that the function uses a context, this context neither can be provided as parameter nor is a SP.ClientContext. It's actually the list context of the currently selected list and will also work with mutliple lists on the page.
