在d3中设置ID问题 [英] Setting an id issue in d3

问题描述

所以这是我在做什么：

selection = canvas.selectAll("circle").data(mydata)

            selection.enter().append("circle")

            selection
                .attr("id", function(d, i){ var result = i+''; return result; })

总之，的每个元素作为其索引的字符串表示。

In short, I'm trying to set the id of each element to be a string representation of its index.

然而，当我以后尝试使用 d3.select（＃1）或者使用数字变量i并且 d3.select（＃+ i.toString（）），似乎没有什么工作。

However, when I try to access that particular element later by using d3.select("#1") or by using a number variable i and going d3.select("#" + i.toString()), nothing seems to work.

我做错了什么？

推荐答案

，显然ids不能以数字开头。

I figured it out, apparently ids can't start with a number.
