I really need help with an aspect of my project. My ultimate goal is to capture the changes made by a user and once they select confirm, post it to SQL for updating. I will use AJAX and PHP for the latter part of the project but I thought JSON would be a great idea to hold all the changes made by a user (the first part).
I am new to JSON and I'm having trouble putting the results in one large object that will be transferred to the server when the user selects "OK". Can someone help me with the coding of this? Is JSON the best way to accomplish the goal (of storing temporary?
Heres what I have so far (just a snippet):
HTML
<div class="button" data-info='2' data-id='8-7' onclick=addDeskid(e)></div>
<div class="button" data-info='4' data-id='2-5' onclick=remDeskId()></div>
<div class="button" value="submit">submit</div>
JS
function addDeskId(e){
$adjustment;
userObject = $(this);
userObjectChange = 'CHANGE_SEAT_TO'; //This is what i will use with AJAX and PHP to determine the SQL statement
userObjectID = userObject.attr('data-info'); //This is the unique SQL ID for the object being modified
userObjectDeskID = userObject.attr('data-id'); //This is the attribute for the object being modified
userObjectSeatID = 9-4; //This is what the attribute is being modified to, for the question, ill make it a solid value
var addUserObject = new jsonAddTest(userObjectID, userObjectChange, userObjectDeskID, userObjectSeatID,);
//this is what the function is actually doing on the user side
//$dragObject.attr("data-id",newSeat); //change desk number for new user location
//$dragObject.attr("previousseat", "T");
//var extPass = e;
//moveOrSetupAccountLog(extPass);
}
function remDeskId(){
userObject = $dropObject.find('div.dragTest');
userObjectChange = 'REMOVESEAT'; //This is what i will use with AJAX and PHP to determine the SQL statement
userObjectID = userObject.attr('data-info'); //This is the unique SQL ID for the object being modified
userObjectDeskID = userObject.attr('data-id'); //This is the attribute for the object being modified
userObjectDeskIDVal = 0; //This is what the attribute is being modified to
var remUserObject = new jsonRemTest(userObjectID, userObjectChange, userObjectDeskID, userObjectDeskIDVal);
//this is what the function is actually doing on the user side
//userObject.attr({"data-id":""}); //remove desk number for new user location
//userObject.appendTo('#userPool');
}
//JSON functions test
function jsonRemTest(id, change, name, seat, value){
this.ID = id;
this.ChangeType = change;
this.Name = name;
this.Seat = seat;
this.setTo = value;
userMoves.push(jsonRemTest);
}
function jsonAddTest(id, change, name, desk, seat, previousseat, previousseatnewvalue){
this.ID = id;
this.ChangeType = change;
this.Name = name;
this.Seat = desk;
this.setTo = seat;
this.PreviousSeatValue = previousseat;
this.PreviousSeatNewValue = previousseatnewvalue;
userMoves.push(jsonAddTest);
}
console.log(JSON.stringify(userMoves));
I am getting the error: userMoves is undefined
. I understand why this is happening but I don't know how to correct it.
TL;DR
Every time the user clicks on this button, it generates an array. I want to combine all the arrays into one object that contains all of them. When the user clicks on a submit button, the object is sent to the server using AJAX/PHP. Is this the best way to do this and if so, how do I combine the output of the JSON functions into one object in preparation for sending?
Thanks in advance
