{"birthday":"1977-07-08","contactInfoList":[],"gender":"男"}形式可以用eval("("+data+")").birthday获得birthday的值
[{"contactInfo_ID":0,"create_Time":""create_Time}]形式相当于一个数组可以用eval("("+data+")")[0].create_Time得到
[{"contactInfo_ID":0,"create_Time":""create_Time},{"contactInfo_ID":0,"create_Time":""create_Time}],{"contactInfo_ID":0,"create_Time":""create_Time},{"contactInfo_ID":0,"create_Time":""create_Time}]
var dataArr=eval("("+data+")"）；
for(var i=0;i<dataArr.length;i++){

alert(dataArr[i].create_Time);

}
