Creating JSON from Alloy UI DataTable

I have created a datatable from JSON using alloyUI and I am pushing a new row each time the "Add Row" button is clicked. After all this is complete I need to create a json of this final collection of data on "Submit" click. But I am unable to find a way to convert a datatable/HTML table (either one will do) to JSON using alloyUI

This is my html and js:

YUI().use('aui-datatable','json-stringify', function(A) {
 
	var data = [
	            {Name: 'Bob', Age: '28',Salary: '10000',Department: 'Admin',Address: 'Kolkata'},
	            {Name: 'Joe', Age: '42',Salary: '20000',Department: 'Accounts',Address: 'Kolkata'},
	            {Name: 'Sarah', Age: '35',Salary: '30000',Department: 'Sales',Address: 'Kolkata'},
	            {Name: 'Billy', Age: '24',Salary: '40000',Department: 'Admin',Address: 'Kolkata'},
	            {Name: 'James', Age: '36',Salary: '50000',Department: 'Accounts',Address: 'Kolkata'},
	            {Name: 'Stark', Age: '51',Salary: '60000',Department: 'Sales',Address: 'Kolkata'}
	          ];
 
	var dtable = new A.DataTable.Base({
		columnset: ['Name', 'Age','Salary','Department','Address'],
		recordset: data
	})
	.render("#container");
	
	
	A.one('#addRow').on('click', function() {
		data.push({
			"Name": A.one('#Name').get('value'),
    		"Age": A.one('#Age').get('value'),
    		"Salary": A.one('#Salary').get('value'),
    		"Department": A.one('#Department').get('value'),
    		"Address": A.one('#Address').get('value')
		});
		dtable.set('recordset', data);
		A.one('#Name').set('value', '');
		A.one('#Age').set('value', '');
		A.one('#Salary').set('value', '');
		A.one('#Department').set('value', '');
		A.one('#Address').set('value', '');
		
	});
	A.one('#submit').on('click', function() {
    //Here I need the code to create JSON  
    });
});

Solution

You need to use JSON.stringify(). Pass it the data that you want to send to JSON. For your example, you should pass dtable.get('recordset'):

A.JSON.stringify(dtable.get('recordset'))

Here's a runnable example using your code:

YUI().use('aui-datatable','json-stringify', function(A) {
 
	var data = [
	            {Name: 'Bob', Age: '28',Salary: '10000',Department: 'Admin',Address: 'Kolkata'},
	            {Name: 'Joe', Age: '42',Salary: '20000',Department: 'Accounts',Address: 'Kolkata'},
	            {Name: 'Sarah', Age: '35',Salary: '30000',Department: 'Sales',Address: 'Kolkata'},
	            {Name: 'Billy', Age: '24',Salary: '40000',Department: 'Admin',Address: 'Kolkata'},
	            {Name: 'James', Age: '36',Salary: '50000',Department: 'Accounts',Address: 'Kolkata'},
	            {Name: 'Stark', Age: '51',Salary: '60000',Department: 'Sales',Address: 'Kolkata'}
	          ];
 
	var dtable = new A.DataTable.Base({
		columnset: ['Name', 'Age','Salary','Department','Address'],
		recordset: data
	})
	.render("#container");
	
	
	A.one('#addRow').on('click', function() {
		data.push({
			"Name": A.one('#Name').get('value'),
    		"Age": A.one('#Age').get('value'),
    		"Salary": A.one('#Salary').get('value'),
    		"Department": A.one('#Department').get('value'),
    		"Address": A.one('#Address').get('value')
		});
		dtable.set('recordset', data);
		A.one('#Name').set('value', '');
		A.one('#Age').set('value', '');
		A.one('#Salary').set('value', '');
		A.one('#Department').set('value', '');
		A.one('#Address').set('value', '');
		
	});
	A.one('#submit').on('click', function() {
      A.one('#json').set('innerHTML', A.JSON.stringify(dtable.get('recordset')));
    });
});
