Two identical records in DataGrid

[mzeddd]

Hi,

How to protect DataGrid from multiple entries of one record?

I have DataGrid where I have some data (loaded from PHP script).
I add new record by colling the following code

Code:

$.post('getData.php?id='+id,
        function(data){
                $('#trTable').datagrid('insertRow',{
                        index: 0,
                        row: jQuery.parseJSON(data)
                });
        }
);

But if I call this code more then once for the same "id" then I have duplicated lines in my datagrid.

Is there any way to protect datagrid from multiple load of one record?

PS: Yes, I know that I can check data before I insert it. But I wonder if datagrid itself could do this kind of job.

It is easy to extend a new method to prevent from inserting duplicate records.

Code:

$.extend($.fn.datagrid.methods,{
	insertUniqueRow: function(jq,param){
		return jq.each(function(){
			var opts = $(this).datagrid('options');
			var rows = $(this).datagrid('getRows');
			for(var i=0; i<rows.length; i++){
				if (rows[i][opts.idField] == param.row[opts.idField]){
					return;
				}
			}
			$(this).datagrid('insertRow',param);
		});
	}
});

Now call 'insertUniqueRow' method to insert your records.

Code:

$.post('getData.php?id='+id,
        function(data){
                $('#trTable').datagrid('insertUniqueRow',{
                        index: 0,
                        row: jQuery.parseJSON(data)
                });
        }
);

this should be part of the build itself.  this just saved me a ton of work!

Thank you!!!!
