Submit multiple rows to php url with one submit

[tooletime]

I have a datagrid that i want to submit all the rows to a php url and i can get it to submit but it asks the success for each one i submit.  i know im missing something easy.  Here is my code.

Code:

function getCart() {
        var ids = [];
        var titles = [];
        var descritptions = [];
        var output = "";
        var rows = $('#cart').datagrid('getRows');
        var emailfrom = $('#emailfrom').val();
	var datastring = "ID=" + rows[i].ID + "&copies=" + rows[i].copies + "&emailfrom=" + emailfrom +"";
	for (var i = 0; i < rows.length; i++)
{
		$.ajax({
					type: "POST",
					url:"echo.php",
					data:datastring,
					cache: false,
					success:  function(result)
					{
						$.messager.confirm('Confirm','Are you sure you want to Submit cart?',
						function (r)
						{
							if (r)
							{
							 $.messager.show({
							  title:'Job Submitted',
							  msg:'Thank you for your job submittal.',
							  timeout:5000,
							  showType:'slide'
							  		}); //messager.show
							            setTimeout( function() {location.reload(); }, 5000);
							}	
							  else
							{
								return false;
								}
			
						});
						}
						
				});		

		}

i figured it out and this is how im doing it.

Code:

function getCart() {
       	var emailfrom = $('#emailfrom').val();
        var rows = $('#cart').datagrid('getRows');
        var data = {};
		var grid = $('#cart');
		var rows = grid.datagrid('getRows');
		$.messager.confirm('Confirm','Are you sure you want to Submit cart?',
			  function (r)
			  {
				  if (r)
				  {
					  for (i=0; i< rows.length; i++)
					  {
						  url = "echo.php?ID=" + rows[i].ID + "&copies=" + rows[i].copies + " + &emailfrom=" + emailfrom +"";
						  $.post(url);
						  }
						  $.messager.show(
						  {
							  title:'Job Submitted',
							  msg:'Thank you for your job submittal.',
							  timeout:5000,
							  showType:'slide'
							  }); //messager.show
							  setTimeout( function() {location.reload(); }, 5000);
							  }
							  else
							  {
								  return false;
					  }
			  });
}
