d3.select by attribute value

Question

I am new to d3. I have something defined like this:

node = node.enter().append(\"circle\")
            .attr(\'id\', function(d){ return d.id; })
            .at         


        

Answer 1

Your problem is that ids and names must begin with a letter. So modify your code to prepend a string to each id, e.g.

.attr('id', function(d){ return 'name' + d.id; })

Then, you can select a given node by using d3.select( '#name' + i ). From the docs on D3 selections:

... you can select by tag ("div"), class (".awesome"), unique identifier ("#foo"), attribute ("[color=red]"), or containment ("parent child").
