Question

I am trying to get the ID of a selected list item using JavaScript. Basically I am trying to get the ID using JavaScript and then in the same javascript redirect to a page with the selected ID in the querystring.

This is my javascript:

function GetID() {
    var ctx = SP.ClientContext.get_current();
    var items = SP.ListOperation.Selection.getSelectedItems(ctx);
    window.location.href = "/_layouts/CustomApplicationPage/CustomApplicationPage.aspx?ID=" + items;
}

But the results I get in my querystring are:

CustomApplicationPage.aspx?ID=[object Object]

Does anyone know how to get the ID of the selected list item or point me to the correct method to use in JavaScript?

Thanks!

The issue is that items is a Dictionary type as described here:

Since you are only trying to get a single value back, you can likely get what you need by referencing the first value in the Dictionary.

window.location.href = "/_layouts/CustomApplicationPage/CustomApplicationPage.aspx?ID=" + items[0].id;
