ObjectUnSetClipPath
将删除剪辑属性 clip-path="url(#clip-path)"
– 而不是 <def>
剪辑路径本身。
但是如果你的clipPath定义被删除,你就不能剪辑任何元素。
function stripClip(el){
let clipPaths = document.querySelector(el).querySelectorAll('clipPath');
if(clipPaths.length){
clipPaths.forEach(function(item, i){
item.remove();
}
)
}
}
svg{
width: 20vw;
}
.clipped{
clip-path: url(#clip-path2);
}
<p><button onclick="stripClip('#svg1')" >remove ClipPath</button></p>

诚然,这不是最方便的方法,但它是可能的:
除了 paper.js 之外,我们还需要一些脚本/帮助程序将 svg 形状(圆形、矩形等)转换为
<path>
元素(我正在使用 'pathThatSvg'
,因为 paper.js 只能基于 2 个路径元素计算新的交叉路径,如下所示:
var intersectionPath = path1.intersect(clipPath);
基于这个答案
var svg = document.querySelector("#svgIntersect");
// set auto ids for processing
function setAutoIDs(svg) {
var svgtEls = svg.querySelectorAll(
"path, polygon, rect, circle, line, text, g"
);
svgtEls.forEach(function (el, i) {
if (!el.getAttribute("id")) {
el.id = el.nodeName + "-" + i;
}
});
}
setAutoIDs(svg);
// convert shapes to paths
function shapesToPath(svg) {
pathThatSvg(svg.outerHTML).then((converted) => {
var tmp = document.createElement("div");
tmp.innerHTML = converted;
svg.innerHTML = tmp.querySelector("svg").innerHTML;
});
}
shapesToPath(svg);
function intersectPath(svg, decimals=2) {
// init paper.js and add canvas
canvas = document.createElement('canvas');
canvas.id = "canvasPaper";
canvas.setAttribute('style','display:none')
document.body.appendChild(canvas);
paper.setup("canvasPaper");
// process clipped elements
var all = paper.project.importSVG(svg, function (item, i) {
item.position = new paper.Point(
item.bounds.width / 2,
item.bounds.height / 2
);
//item.scale(0.5, new Point(0, 0) )
var items = item.getItems();
var ids = item._namedChildren;
var groups = item.children;
groups.forEach(function (gr, i) {
var group = gr["_namedChildren"];
if (group) {
for (key in group) {
//get clip path
var clip = group["clipPath"][0];
if (key !== "clipPath") {
var el = group[key][0];
//get intersection path and generate d commands
var elClipped = el.intersect(clip);
var elClippedD = elClipped
.exportSVG({ precision: decimals })
.getAttribute("d");
// select path by id and overwrite d attribute
var newEl = svg.querySelector("#" + key);
newEl.setAttribute("d", elClippedD);
}
}
}
});
// remove clip defs and attributes
var clippedEls = svg.querySelectorAll("[clip-path]");
clippedEls.forEach(function (clippedEl, e) {
clippedEl.removeAttribute("clip-path");
});
svg.querySelector("defs").remove();
svg.classList.add("svg-intersect");
console.log(svg.outerHTML)
});
}
