Javascript 文數字的排序

以字母排序時, 會遇到排成 chr1, chr17, chr9 , 如果想排成 chr1,chr9,ch17 則需要取出內容再轉成數字, 解法:

let a = "chr17_gl0000204";
let matches = str.match(/\d+/g);
// ['17', '0000204']

How to split alphanumeric string but keep last alpha value javascript:

string.match(/[a-z]+|\d+/ig)

---

完整範例：

function isNumeric(value) {
    return /^-?\d+(\.\d+)?$/.test(value);
}

function format_alpha_to_num(s) {
    let new_s = [];
    if(s.length) {
        let num_matches = (s).match(/[a-zA-Z]+|\d+/g);
        if(num_matches) {
            num_matches.forEach((element) => {
                if(isNumeric(element)) {
                    let t = "00000000" + element;
                    new_s.push(t.substring(t.length-8, t.length));
                } else {
                    new_s.push(element);
                }
            });
        }
    }
    return new_s.join('');
}

sort_value = format_alpha_to_num(label_value);
