私は強制的な有向グラフで演奏しています。ノードの変更時にそのテキストをマウスの上に置いてデータから別のテキストに変更しました。D3フォースレイアウトのノードラベルに改行を挿入する

あなたは私のjsfiddleでの作業の例を見ることができます：私を悩ますコードのhttp://jsfiddle.net/dzorz/6pHkn/
一部は、マウスオーバーです：
else if(d.entity == "employee"){
d3.select(this).select('text')
.transition()
.duration(300)
.text(function(d){return d.prefix + ' ' + d.fst_name + ' ' + d.snd_name})
.style("font-size","8px")
}
の間に改行を追加したいとd.snd_nameと私は'\n'と'<\br>'にしようと、それは私が取得したい何をやっていませんでした...テキストに改行を追加するD3での方法がある

このメソッドを使用しようとしましたが、実装方法がわかりません.htmlでエラーが発生しているので、誰かが私に道を示すことができると思っていました – dzordz
