本來如果可以寫後臺代碼，用SQL語句再經過處理就可以得到想要的數據
但是由於後臺不是我寫的，所以只能從後臺取到這些數據，想要正確展示出來就必須要處理一下，貼代碼吧，有註釋
able_json = xmlhttp.responseText;
var obj = JSON.parse(table_json);
alert(table_json)
//從json數據取出月份，不重複的月份，存入新的數組
var mon = [];
for (var i = 1; i < obj.length; i++) {
var repeat = false;
for (var j = 0; j < mon.length; j++) {
if (mon[j] == obj[i].clickdate.substring(0,7)) {
repeat = true
break
}
}
if (!repeat) {
//不重複push 結果數組
mon.push(obj[i].clickdate.substring(0,7))
}
}
//對月份的數組進行遍歷，從整個json數據中遍歷每月份的值求和
var monvalue = [];
var one = 0;
for(var j = 0;j<mon.length;j++){
var one = 0;
for(var i=0;i<obj.length;i++){
if(obj[i].clickdate.substring(0,7) == mon[j]){
one += parseInt(obj[i].value);
}
}
monvalue.push(one);
}
//把獲取到的兩個數組組合爲一個數組，
var json_arr = [];
for (var i=0;i<mon.length;i++){
// json_arr[mon[i]] = monvalue[i];
json_arr.push([mon[i],monvalue[i]]);
}
//循環數組並打印信息
var table1 = "<table id='table1' border='1'>"
table1 +="<tr style='font-weight:bold; font-size:15px; background-color:#CCC;'><td>日期</td><td>上網人數</td></tr>";
for(var i =0;i<json_arr.length;i++){
var v = json_arr[i];
table1 += "<tr><td>"+v[0]+"</td><td>"+v[1]+"</td></tr>"
}
table1 +="</table>";
$("#table_area").html(table1);
$("#table1 tr:odd").addClass("trlinebg");雖然過程麻煩了點，我也知道肯定有簡便點的方法，但是項目很急，本人又是小白一隻，只好這樣先實現，後期再去優化了。請大牛指點
