在控制台中执行svg.getAttribute（“ d”）时，我有一串数字：
“-0.05990783410138251,0.13594470046082952，-0.06912442396313362,0.14976958525345618，-0.07603686635944701,0.15668202764976957，-0.08755760368663595,0.16589861751152069，-0.09677419354838718,0.16820276497695852，-0.10599078341013829,0.16820276497695852，-0.12211981566820279,0.16820276497695852，-0.13594470046082957,0.16820276497695852，-0.14055299539170513,0.16820276497695852，-0.14516129032258068,0.16589861751152069 ，-0.1474654377880184“
我希望将其转换为浮点数，所以我做了parseFloat（svg.getAttribute（“ d”））但我得到的只是第一个数字：
-0.05990783410138251
我如何获得所有数字？
谢谢
最佳答案
使用String.prototype.split()和Array.prototype.map()可以得到一个浮点值数组，如下所示：
const values = '-0.05990783410138251,0.13594470046082952,-0.06912442396313362,0.14976958525345618,-0.07603686635944701,0.15668202764976957,-0.08755760368663595,0.16589861751152069,-0.09677419354838718,0.16820276497695852,-0.10599078341013829,0.16820276497695852,-0.12211981566820279,0.16820276497695852,-0.13594470046082957,0.16820276497695852,-0.14055299539170513,0.16820276497695852,-0.14516129032258068,0.16589861751152069,-0.1474654377880184';
const floats = values.split(',').map(parseFloat);
console.log(floats);
