所以这就是我所拥有的:

<path class="..." onmousemove="show_tooltip(event,'very long text 
    \\\n I would like to linebreak')" onmouseout="hide_tooltip()" d="..."/>

<rect class="tooltip_bg" id="tooltip_bg" ... />
<text class="tooltip" id="tooltip" ...>Tooltip</text>

<script>
<![CDATA[
function show_tooltip(e,text) {
    var tt = document.getElementById('tooltip');
    var bg = document.getElementById('tooltip_bg');

    // set position ...

    tt.textContent=text;

    bg.setAttribute('width',tt.getBBox().width+10);
    bg.setAttribute('height',tt.getBBox().height+6);

    // set visibility ...
}
...

现在我很长的工具提示文本没有换行符,即使我使用alert(); 它告诉我,文本实际上有两行.(它包含一个"\",但是如何删除那个呢？)
我无法让CDATA在任何地方工作.

所以,我正在使用强制定向图,我已经将我的节点上的.text更改为鼠标移到数据中的另一个文本.

我的代码看起来像这样:

脚本:
