$.post() 方法使用 HTTP POST 請求從伺服器載入資料。

$(selector).post(URL,data,function(data,status,xhr),dataType)

示例：

function getDeviceRolenameList(selet,deviceRoles,callback){
    $.post("URL",function(json){
    	//debugger;
        var resultList = json.resultList;
        var optionHtml = "";
        deviceRoleArray = deviceRoles.split(",");
        console.log(deviceRoleArray);
        for(var i in resultList){
            var id = resultList[i].id;
            var name = resultList[i].name;
            var selected = "";
            for(var j in deviceRoleArray){
                if(id == deviceRoleArray[j]&&deviceRoleArray[j]!=""){
                    selected = "selected";
                }
            }
            optionHtml += "<option value='"+id+"' "+selected+">"+name+"</option>";
        }
        $(selet).html(optionHtml);
        $(selet).select2({
            placeholder: "選擇裝置角色",
            allowClear: true,
            escapeMarkup: function (m) {
                return m;
            }
        });
        if(callback){
            callback();
        }
    });
}
