How to get variable attribute in d3
d3.js, javascript
Solution
Yes. Select `this` and then use the usual functions to access properties.
Problem
How do I return a specific attribute of a variable using d3? For example, I want to select an element by mouseover, and pass on the selection to a function, but only if the element's `id` is a particular name. Something like this? ``` d3.select("body").on("mouseover", function(){ if (d3.select(this).attr("id") == "correct") { enableInteraction(d3.select(this)); } }); ```
