Stop Force Layout on d3js and start free dragging nodes

Question

I\'m using the force layout to represent a directed unweighted network. My inspiration comes from the following example: http://bl.ocks.org/mbostock/1153292

Answer 1

function nameOfFunction () {
    d3.selectAll(".classOfYourNodes").each(
        function(d) {
            d.fixed = true;
        }
    )
}

The method .each calls the anonymous function, which in this case sets the "fixed" attribute to true for every node within the selection.

Edit: The above is in regards to your comment about wanting to stop all of the nodes and not have the force simulation continue when you drag a node, as calling force.stop() does.
