与往常一样，Internet Explorer导致兼容性问题。这次是使用d3.js构建的树形图。我的树在其他浏览器中工作，但是当我在Internet Explorer 11中加载页面时出现以下错误：
SCRIPT5007: Unable to get property '0' of undefined or null reference
带有指向错误行的链接：
d3.select(this.parentNode.children[0]).attr('height', 21 * (lineNumber + 1));
我已经完成了对this question的每个回答以及尝试使用aight.js，但无济于事。我还尝试使用元标记<meta http-equiv="X-UA-Compatible" content="IE=Edge" />并更新了d3.min.js脚本。
IE中唯一加载的是一些非常破碎，被压扁，功能失调的svg外观。有任何想法吗？
更新
Here is a JSFiddle我的代码，以及我正在使用的jquery和d3的版本。

事实证明，Internet Explorer不喜欢$text = "3.2 Mark one answer
You must NOT sound your horn

area
at any time in a built-up area

preg_match_all("/^\h{1}.+?[\r\n]{1}(\H*?\b(?=[\r\n]{1}))?/im", $text, $matches);
echo "<pre>";
var_dump($matches[0]);
// the output:
array(4) {
[0]=>
string(43) " between 10 pm and 6 am in a built-up

[1]=>
string(32) " at any time in a built-up area

[2]=>
string(45) " between 11.30 pm and 7 am in a builtup

[3]=>

}
。
要让parentNode.children[0]的第一个孩子使用parentNode。这使脚本与IE兼容。
