javascript - 将类似字符串的数组替换为带有字符替换的数组

Question

我有一个像这样的字符串 "12,a,{3,4},b,c" ，我需要将其转换为一个数组，其中大括号中的元素应该是子数组，结果应该是这样的

["12","a",[3,4],"b","c"]

对于其他例如:

"12,a,b,c,{e,f}"--> ["12","a","b","c", ["e","f"] ]

"{12,a},b,c,{c,d}"--> [["12","a"],"b","c", ["e", “f”]]

Answer 1

您可以尝试以下代码:

a = "{12,a},b,c,{c,d}";
m = a.match(/{[^}]*}|[^,]+/g);
arr=[];

for (i=0; i<m.length; i++) {
    if (m[i].indexOf('{') >= 0)
        arr.push(m[i].replace(/[{}]/g, "").split(/,/));
    else
    arr.push(m[i]);
}
console.log(arr);

输出:

[[12,a],b,c,[c,d]]
