Insert record using jQuery after ajax call doesn't work

I have an insert and load record (jQuery & PHP) script working fine without using AJAX. but after the AJAX call, insert (jQuery) doesn't work.

This is my code:-

    $(".insert").live("click",function() {

        var boxval = $("#content").val();
        var dataString = 'content='+ boxval;
        if(boxval==''){
            alert("Please Enter Some Text");
        }
        else{
            $.ajax({
                type: "POST",
                url: "demo.php",
                data: dataString,
                cache: false,
                success: function(html){
                    $("table#update tbody").prepend(html);
                    $("table#update tbody tr").slideDown("slow");
                    document.getElementById('content').value='';
                }
            });
        }
        return false;
    });

    $(".load").live("click",function() {
        $.ajax({
                type: "POST",
                url: "test.php",
                success: function(msg){
                    $("#container").ajaxComplete(function(event, request, settings){
                        $("#container").html(msg);
                    });
                }
            });
    });
});

I solved the problem

I replaced this code

$("#container").ajaxComplete(function(event, request, settings){
    $("#container").html(msg);
});

with

$("#container").html(msg);

Thank you very much for your answers

I'd be curious to see your form markup and your back-end PHP code; it may provide a clue.

Often I'll have a form variable called 'action', just to tell the PHP code what I want it to do (especially if that PHP script is a controller for many different actions on an object). Something like <input type="hidden" name="action" value="insert"/> or even multiple <input type="submit" name="action"/> buttons, each with a different value. In the PHP code I'll have something like:

switch ($_POST['action']) {
    case 'insert':
        // insert record and send HTML
    break;
    // other actions
}

If you've done something like this, perhaps the PHP is looking for the presence of a variable that doesn't exist.

Without being able to look at your code, I'd highly recommend the incredibly handy jQuery Form Plugin http://jquery.malsup.com/form/ . It allows you to turn a form into an AJAX form, formats your data properly, and doesn't forget the data from any of your form elements (except <input type="submit"/> buttons that weren't clicked on, which is the same behaviour that a non-AJAX form exhibits). It works just like the standard $.ajax() method.

Definitely recommend using your browsers dev tools to examine the exact request that is submitted and see if there is a problem there first.

You might also want to change the way you pass the dataString to the ajax request.

If your boxval has a "&" in it then you'll end up with an incorrectly formatted string. So, try initialising data instead as:

var data = {};
data.content = boxval;

This will ask jQuery to escape the values for you.
