lets say your JSON data looks like this:

JavaScript

[
   { textBoxId: "title0", value: "some value" },
   { textBoxId: "title1", value: "some other value" }
]

then your routine to set the values should be this:

JavaScript

$.each(jsonData.d, function(index, item){
    $('#' + item.textBoxId).val(item.value);
});

if the Id of the textbox coming back from the server isnt the client id of the textbox modify the .value js to

JavaScript

$('input[id*="' + item.textBoxId + '"]').val(item.value);
