 var randomdate = new Date().getTime();
 
    var changePassword = {};
    changePassword.paramOldPwd = paramOldPwd;
    changePassword.paramNewPwd = paramNewPwd;
    changePassword.paramAffirmPwd = paramAffirmPwd;
$.ajax({
                url: '/ConnectStatus/SaveNodeInfo?randomDate=' + randomdate,
                dataType: "json",
                type: "post",
	            data: {

                success: function (json) {
                    if (json.Explain == 'OK') {
