JavaScript实现解析INI文件内容的方法

function parseINIString(data){
  var regex = {
    section: /^\s*\s*([^]*)\s*\]\s*$/,
    param: /^\s*([\w\.\-\_]+)\s*=\s*(.*?)\s*$/,
    comment: /^\s*;.*$/
  };
  var value = {};
  var lines = data.split(/\r\n|\r|\n/);
  var section = null;
  lines.forEach(function(line){
    if(regex.comment.test(line)){
      return;
    }else if(regex.param.test(line)){
      var match = line.match(regex.param);
      if(section){
        value[section][match[1]] = match[2];
      }else{
        value[match[1]] = match[2];
      }
    }else if(regex.section.test(line)){
      var match = line.match(regex.section);
      value[match[1]] = {};
      section = match[1];
    }else if(line.length == 0 && section){
      section = null;
    };
  });
  return value;
}
