Question

I am posting some data to the server using JQuery.post(), as shown below. When I receive the post data on the server side, I am surprised to see that the post variables already have single apostrophes converted to html numbers (ie. ‘ is replaced with '). How is this happening? Does the conversion happen in Jquery.post()? I cannot find any documentation on this.

$("#save").click(function(event) {
    event.preventDefault();

    var postdata = "id="+id+"&note="+$("#note").val();

    $.post("save_note.php", postdata, function(data){
    $('#save_status').text(data);
    });
});

It’s happening in the web browser.

Check the value of $("#note").val() – remember under the covers when you type something in a form field it’s being inserted into the HTML DOM.
