如何阻止 SVG 文本悬停停止渐变填充

Question

我希望 svg 背景填充渐变即使悬停在文本上也能保持填充状态，但是当您将鼠标悬停在文本上时会清除填充。

我尝试移动文本，甚至移动 "flag" class，但没有成功。非常感谢。

我已经包含代码笔在这里：https://codepen.io/daneli84/pen/OJVZmeJ

CSS

/* grid styling */
use {
cursor: pointer;
fill:transparent;
}

g {cursor: pointer;}

filter: url(#filter-1);
fill: url(#grad2);
}

/* other styling */
svg {
width: 700px;
flex: 1;
}

body {

splay: flex;
justify-content: center;
align-items: center;
flex-direction: column;
margin: 0;

}

JS

// 
var flagBlur = document.querySelector('.flag-blur');
var flags = document.querySelectorAll('.flag');


// 
function startPage() {
flags.forEach(flag => {
flag.onmouseover = function() {
flag.classList.add('filter-class')
TweenMax.fromTo(flagBlur, 1, {
attr: {

}, {
attr: {
stdDeviation: 1.2
},
ease: Power1.easeInOut
});
}

flag.onmouseleave = function() {
flag.classList.remove('filter-class')
}
})
}
startPage();

您可以在文本元素上使用 pointer-event 属性

<text
  class="h1"
  alignment-baseline="middle"
  text-anchor="middle"
  font-family="Verdana"
  font-size="5"
  fill="blue"
  pointer-events="none"
>CNI</text>

The pointer-events attribute is a presentation attribute that allows defining whether or when an element may be the target of a mouse event.
