//驼峰转短横线
function toKebabCase(str) {
let res = str.replace(/([A-Z])/g, (all, i) => {
return "-" + i.toLowerCase();
});
if (res.slice(0, 1) === "-") {
res = res.slice(1); //去除开头的-
}
return res;
}
//短横线转驼峰
function toCamelCase(str) {
return str.replace(/-([a-zA-Z])/g, function (all, i) {
return i.toUpperCase();
});
}
console.log(toCamelCase("get-element-by-id"));
console.log(toKebabCase("GetElementById"));
