Knockout JS: Create Json from ViewModel Observable Array

kaka1234

I have an HTML table whose columns are dynamically created. There are Add Row buttons to add rows to the table and Delete Row buttons to delete rows. Finally, there is a "save" button where I want to get all the data from the input table and send it to my mvc controller in json format.

The table settings are all ok. My only problem is creating json from observable array. Here is my fiddle:

https://jsfiddle.net/4djn2zee/1/

If you click Add one or more rows, then enter data in both rows. If you press the save button, you can observe the following:

self.valuesData()

Now, if you see this value in the console, the result is:

(2) [ValuesData, ValuesData]

To expand further:

(2) [ValuesData, ValuesData]
0:ValuesData {ID: "1", Co1: "2", Col2: "3", Col3: "4", Col4: "5", …}
1:ValuesData {ID: ƒ, Co1: ƒ, Col2: ƒ, Col3: ƒ, Col4: ƒ, …}
length:2
__proto__:Array(0)

Since I added 2 rows, I can see 2 arrays.

Now if you see above, I can see my data in the first row id, col1, col2, etc. The problem I'm having is how to get the data from the observable and construct my json.

I expect my json to look like this:

{
"ID": "1",
"Co1": "2",
"Col2": "3",
"Col3": "4",
"Col4": "5",
"Col5": "6",
"Comment": "7"
},
{
"ID": "8",
"Co1": "9",
"Col2": "10",
"Col3": "11",
"Col4": "12",
"Col5": "13",
"Comment": "14"
}

renew:

I tried as follows:

    var dataToSave = $.map(self.valuesData(), function(item) {
    var jsonToSend = {};



    return jsonToSend;
  });

Again as stated on the first row, I can see the data, but not sure how to get the data from the second row and beyond.

Here is my updated fiddle:

Try this:

var dataToSave = ko.toJSON(self.valuesData);
