Losing unicode Char when sending via query string in an AJAX call

Question

Hello all,

I'm trying to send some data in an Ajax call to update a record in the server

 var OrderNotes = $.ajax({
                 url:'AjaxActions/OrderNotesUpdate.aspx?OrderID=' + OrderID + '&Notes=' + $('#txtNotes').val(),
                 async:false                 
               }).responseText;

"Notes" are in unicode.

When i'm checking the querystring on the receiving page i'm getting not getting the same code (not the text i'v enterd).

Any one knows any thing about it? is it becouse the data is from an asp.net textbox? what can i do about it?

p.s before sending i checked and every things is as it should, just in the querystring every thing going wrong... 10x

jQuery.ajax({
            url:'AjaxActions/OrderNotesUpdate.aspx',
            data:{
                 OrderID:OrderID,
                 Notes:$('#txtNotes').val()
                 },
           async:false,
           type:'get',
           success:function(data)
                   {
                    //do something here
                    }
})

First of all the answer of Praveen Prasad I find correct. I want only to add a little description which will be answeron the question "Why ... ?" and not "How ... ?".

If parameter which you send to the server per HTTP GET has some special characters then there can not be used in URL without encoding, so you have to use at least

url:'AjaxActions/OrderNotesUpdate.aspx?OrderID=' +
    encodeURIComponent(OrderID) + '&Notes=' + encodeURIComponent($('#txtNotes').val())

Next step: you can use jQuery.param() to encode URL parameters with respect of encodeURIComponent and place '&' character between paramters:

$.ajax({
    url:'AjaxActions/OrderNotesUpdate.aspx?' +
        $.param({OrderID: OrderID, Notes: $('#txtNotes').val()}),
    async:false})

or

$.ajax({
    url:'AjaxActions/OrderNotesUpdate.aspx' +
    data: { OrderID: OrderID, Notes: $('#txtNotes').val()},
    async:false})

which place '?' between url and data encoded by $.param if url don't already contain '?' otherwise it use '&' instead.

Next: you should try to use asynchrone version of $.ajax whenever it is possible. One needs see more parts of your code to help you. In general it should be

$.ajax({
    url:'AjaxActions/OrderNotesUpdate.aspx' +
    data: { OrderID: OrderID, Notes: $('#txtNotes').val()},
    success:function(response) {
        /* here use can use response.responseText. For examlpe you can
           code which call the syncrone $.ajax before and used
           the return value here */
    }
})
