how to access result property of Success function of jquery

I have a success fun开发者_如何学编程ction of jQuery defined as:

success: function(result) {
    var htmlString = [result];
    for (i = 0; i < htmlString.length; i++) {
        $('#MyGrid tbody').append('<tr><td><a href="#">' + htmlString[i].name+ '</a></td><td><a href="#" class="remove">Remove</a></td></tr>');
    }
},

And an event handler bound with delegate:

$('#MyGrid').delegate('a.remove', 'click', function() {
    var name= ;$(this).closest('tr').find("td").eq(0).find('a').text();
    var number = ; //here i need to access htmlString[i].number
    alert(number);
}

How can I assign htmlString[i].number to the number variable?


there may be better ways but one way is to on the success callback assign the result to some global scope variable and access it in the delegate call

else you can do it this way assign the htmlString[i].number to the rel tag

success: function(result) {

                var htmlString = [result];
                for (i = 0; i < htmlString.length; i++) {

                $('#MyGrid tbody').append('<tr><td><a rel="'+htmlString[i].number+'" href="#">' + htmlString[i].name+ '</a></td><td><a href="#" class="remove">Remove</a></td></tr>');
                }

            },

and in the delegate call

     $('#MyGrid').delegate('a.remove', 'click', function() {

                var name= $(this).closest('tr').find("td").eq(0).find('a').text();
                var number =  $('#MyGrid').delegate('a.remove', 'click', function() {

                var name= $(this).closest('tr').find("td").eq(0).find('a').text();
                var number = $(this).closest('tr').find("td").eq(0).find('a').attr('rel');
                alert(number);
    }
            alert(number);
}


This seems like a perfect use case for .data():

/*snip */
for (i = 0; i < htmlString.length; i++) {
    var $row = $('<tr><td><a href="#">' + htmlString[i].name + '</a></td><td><a href="#" class="remove">Remove</a></td></tr>');
    $row.find("a.remove").data("number", htmlString[i].number);

    $('#MyGrid tbody').append($row);
}

Then in your event handler:

$('#MyGrid').delegate('a.remove', 'click', function() {  
    var number = $(this).data("number");
    alert(number);
});

Here's a working example: http://jsfiddle.net/BRZD7/
