我试图弄明白为什么svg会在工具提示中删除文本。
以下是xml代码：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg onload="init(evt)"

    <style>

有问题的工具提示就是此代码段中的提示：

<text fill="#000000" font-family="sans-serif" font-size="13" lengthAdjust="spacing" textLength="93" x="43" y="213.5107">
            <a onmousemove="ShowTooltip(evt, 'otherVar ← {{PATH2}} saveV ← {{PATH}}')" onmouseout="HideTooltip(evt)">
validation data 1</a>
        </text>

我以为我的 ShowTooltip 函数，在调用中 tooltip.getComputedTextLength() 将计算正确的所需长度。我试着用样式标签做实验，增加了 textLength 改变 lengthAdjust 但它不起作用。我能做些什么来解决这个问题？

一个想法是在专用框中显示所有工具提示（参见一些视频游戏）。箱子可以位于固定位置，并具有静态或动态尺寸。这样，您就可以为弹出窗口保留一个位置，并可以对所有内容进行样式设置并相应地规划输出。
您甚至可以检查悬停元素的位置，如果它位于图像的上半部分，请在下半部分绘制工具提示框，反之亦然。
