Removing fixed classes does not properly remove them from the presetation

问题

Concerning: Remove all .fixed classes from force layout nodes with jQuery

I can remove the fixed classes now. But the nodes are still fixed in the view.

So simply removing the class is not enough I believe. I didn't find any help in the docs of D3 as well.

回答1:

Are you wanting to go back to the force layout ?

Its because you have only removed the class not the actual fixed property.

Try this :

 d3.selectAll(".node") //select your node here
    .each(function(d){d.fixed = false;})
    .classed("fixed", false);
 force.start(); //-bring the force layout back
