Question

我目前有以下d3代码。

<script>


  var dataset = [14, 5, 26, 23, 9];

  d3.select("body").selectAll("p")
.data(dataset)
.enter()
.append("p")
.text(function(d) {
  if (d > 10)
  {
    return "Warning: Joe watched " + d + " cat vidoes today.";
  }
  else {
    return "Joe watched " + d + " cat vidoes today.";
  }});

如何使用外部CSS将{return“警告...”}部分变为红色？非常感谢您的帮助！

Answer 1

如果要使用外部css，则可以将文本元素与类关联：

"گدھا"

您还可以使用public string Replacement(string input, string replacement) { string[] words = input.Split(' '); string result = string.Empty; for (int i = 0; i < words.Length; i++) { if(words[i].Contains('/')) { int barIndex = Reverse(words[i]).LastIndexOf('/') + 1; int removeLenght = words[i].Substring(barIndex).Length; words[i] = Reverse(words[i]); words[i] = words[i].Remove(barIndex, removeLenght); words[i] = words[i].Insert(barIndex, Reverse(replacement)); string ToReverse = words[i]; words[i] = Reverse(ToReverse); break; } } for(int i = 0; i < words.Length; i++) { result += words[i] + " "; } result = result.Remove(result.Length - 1); return result; } public string Reverse(string s) { char[] charArray = s.ToCharArray(); Array.Reverse(charArray); return new string(charArray); } setter直接从javascript设置颜色：

.attr("class", function() { return d > 10 ? "red_text" : "green_text" });
