How to get specific listview data with javascript?

Question

I got a list and a list view. But I want to retrieve only particular list view's data.

How can i do that with javascript ?

Answer 1

There's a lot of advantages to doing this. The trick is to get the caml query off of the list view before querying the list for items.

var ctx = new SP.ClientContext.get_current(),
    list = ctx.get_web().get_lists().getByTitle(<list title>),
    views = list.get_views(),
    view = views.getByTitle(<view name>),
    items;

ctx.load(views);
ctx.executeQueryAsync(
    function(){
        var camlQuery = new SP.CamlQuery();
        camlQuery.set_viewXml(view.get_listViewXml());
        items = list.getItems(camlQuery);
        ctx.load(items);
        ctx.executeQueryAsync(
            function(){
                //items variable will be populated with items from view
            },
            function(sender, args){
                console.error('List items could not be retrieved');
            }
        );
    },
    function(){}
);

The down side is that there's 2 execute's in order to make this work. one in order to get the data from the list view, the 2nd one to pass in the query pulled from the specific view.

I have a few gists that I use this on for utility sake.
