基于JavaScript将表单序列化类型的数据转化成对象

[
  {
    name: "startTime"
    value: "2015-12-02 00:00:00"
  },
  {
    name: "endTime"
    value: "2015-12-25 23:59:59"
  }
]

{
  "startTime": "2015-12-02 00:00:00"
  "endTime": "2015-12-25 23:59:59"
}

  var properties = serializedParams.split("&");
  for (var i = 0; i < properties.length; i++) {
    //处理每一个键值对
    evalThem(properties[i]);
  }; 

    var strAry = new Array();
    strAry = str.split("=");
    //使用decodeURIComponent解析uri 组件编码
    for(var i = 0; i < strAry.length; i++){
      strAry[i] = decodeURIComponent(strAry[i]);
    }
    var attributeName = strAry[0];
    var attributeValue = strAry[1].trim(); 

 if(strAry.length > 2){
      for(var i = 2;i<strAry.length;i++){
        attributeValue += "="+strAry[i].trim();
      }
    } 

   if(!attributeValue){
      return ;
    } 

 var attriNames = attributeName.split("."),
      curObj = obj;
    for(var i = 0; i < (attriNames.length - 1); i++){
      curObj[attriNames[i]]?"":(curObj[attriNames[i]] = {});
      curObj = curObj[attriNames[i]];
    }
    curObj[attriNames[i]] = attributeValue.trim(); 

eval("obj."+attributeName+"=\""+attributeValue.trim()+"\";"); 

/
serializedParams格式为"key1=value1&key2=value2". 
也支持'key.sonkey=value' 
 /
function paramString2obj (serializedParams) {  
  var obj={};
  function evalThem (str) {
    var strAry = new Array();

    //如果值中包含"="符号，需要合并值

    //使用赋值方式obj[attributeName] = attributeValue.trim();替换

    //解决值attributeValue中包含单引号、双引号时无法处理的问题
