[ 看到它在行动 ]

var str = "http://www.somewhere.com/index.html?field[]=history&field[]=science&field[]=math";

var match = str.match(/[^=&?]+\s*=\s*[^&#]*/g);
var obj = {};

for ( var i = match.length; i--; ) {
  var spl = match[i].split("=");
  var name = spl[0].replace("[]", "");
  var value = spl[1];

  obj[name] = obj[name] || [];
  obj[name].push(value);
}

alert(obj["field"].join(", "))??
