html5 – 在Chrome 48中不推荐使用PathSegList并将其删除

在Chrome 48中,删除了PathSegList.当我读到另一个问题“ Alternative for deprecated SVG pathSegList”的答案时,Chrome正在提供一个新的API,但我想这个新的API尚不可用.什么是另一种选择,我该如何使用它.我知道这是重复的,但我提到的链接并没有帮助我.

解决方法

您不需要path seg polyfill(pathSeg.js).

使用path data polyfill,您可以将路径数据编辑为公共数组对象.

使用path data polyfill处理新API.这是推荐的.

var path = document.querySelector('path'); //your <path> element
//Be sure you have added the pathdata polyfill to your page before use getPathData
var pathdata = path.getPathData();
console.log(pathdata);
/*
  you will get an Array object contains all path data details
  like this:
    [
        { "type": "M","values": [ 50,50 ] },{ "type": "L","values": [ 200,200 ] }
    ]
*/

//replacement for createSVGPathSegMovetoRel and appendItem
pathdata.push({type:'m',values:[200,100]});
path.setPathData(pathdata);

//replacement for createSVGPathSegMovetoAbs and appendItem
pathdata.push({type:'M',values:[300,120]});
path.setPathData(pathdata);

//replacement for createSVGPathSegLinetoAbs and appendItem
pathdata.push({type:'L',values:[400,120]});
path.setPathData(pathdata);

console.log(path.getAttribute('d'));

//create a new path data array
var pathdata  =  [
    { "type": "M",200 ] }
];
path.setPathData(pathdata);
console.log(path.getAttribute('d'));
