d3.select by attribute value
d3.js, javascript, jquery
Solution
Your problem is that `id`s and `name`s 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").
Problem
I am new to d3. I have something defined like this: ``` node = node.enter().append("circle") .attr('id', function(d){ return d.id; }) .attr("class", "node") .on('mouseover', mouseover_node) .on("click", nodeClick); ``` Now in function nodeClick I want to access a node (or circle) with a special id. I am looking for something that I could use like this: ``` for(var i=0;i<maxId;i++) { d3.select(the node with id = i).do.... ``` Does anybody know how I can do this?
