javascript里你绝对用的上的字符分割函数--原创

// 在数组内字符为未知情况下，合并和分割的解决方案

var data = [['your name', 'myvalue'], ['myr name', 'thivalue']];

function string_join(data) {
   var str = '', arr = [];
   for (var i = 0; i < data.length; i++) {
     for (var j = 0; j < data[i].length; j++) {
       data[i][j] = slash(data[i][j]);
     }
     arr.push(data[i].join('/'));
   }
   return arr.join(',');
}

function slash(string) {
  return String(string).replace(/[\\/,]/g, '\\$&');
}

function string_split(string) {
  var c,
      cur_str = '',
      cache = [],
      result = [];
  for (var i = 0; i < string.length; i++) {
    c = string.charAt(i);
    switch(c) {
      case '\\':
        cur_str += string.charAt(++i);
        break;
      case '/':
        cache.push(cur_str);
        cur_str = '';
        break;
      case ',':
        cache.push(cur_str);
        cur_str = '';
        result.push(cache);
        cache = [];
        break;
      default:
        cur_str += c;
    }
  }

  if (cur_str.length) {
    cache.push(cur_str);
  }

  if (cache.length) {

  return result;
}

var before = string_join(data);
console.log(before);
var after = string_split(before);
