过滤打字稿中枚举键的公用子字符串

Question

我有两个枚举映射，并希望为枚举键创建一个数组，以删除数组中的公共子字符串，因此我也可以将其用于其他枚举映射。 枚举格式为

enum Test {
   test_value_error = 1;
   test_value_log = 2;
   test_value_main = 3;
   test_value_acknowledge = 4;}

enum Test1 {
   short_set_measure = 5;
   short_set_log_check = 6;
   short_set_finite_check = 7;}

in this case I want to remove common substring from two enum map using a common function and convert it to array. So far I have been able to filter it to array format but can't filter out substring. 
below is my code.

function toArray（enumname：object）{ 返回Object.keys（obj）.map（key => key.replace（/ _ / g，''））;}

Still new to typescript so any help will be beneficial

简短回答

您在寻找这个吗？

enum Test {
  test_value_error = 1,
  test_value_log = 2,
  test_value_main = 3,
  test_value_acknowledge = 4
}

function toArray(enumname: object) {
  return Object.keys(enumname).map(key => key.replace(/test_value/g, ""));
}

const arr = toArray(Test);

console.log(arr);

它从每个键中删除test_value。输出看起来像这样：

[ '1', '2', '3', '4', '_error', '_log', '_main', '_acknowledge' ]

替代项

// [ '1', '2', '3', '4', 'error', 'log', 'main', 'acknowledge' ]
function toArray(enumname: object) {
  return Object.keys(enumname).map(key => key.replace(/test\_value\_/g, ""));
}

// [ 'error', 'log', 'main', 'acknowledge' ]
function toArray(enumname: object) {
  return Object.keys(enumname)
    .filter(key => !parseInt(key))
    .map(key => key.replace(/test\_value\_/g, ""));
}
