Getting text area using getBBox()

Question

var text = vis.selectAll(\"text\")
    .data(words, function(d) { return d.text.toLowerCase(); });
    text.enter().append(\"text\")
    .attr(\"text-anchor\", \"mid         


        

Answer 1

The best approach here depends on what you're trying to do. Most d3 callback functions will supply the current DOM element as this, so this should work:

text.each(function() {
    console.log(this.getBBox());
});

Beyond that, the question is the context in which you need to use that number. For example, to get the sum of the text widths, you could do:

var textWidth = 0;
text.each(function() {
    textWidth += this.getBBox().width;
});

Answer 2

You can also do this synchronously on an element by using node():

console.log(text.node().getBBox());
