使用jQuery的警报消息

Question

I need to output alert message if val = -1, but the problem is that this message appears at the bottom of the page and this does not depend on the value of val.

if ($val == -1) 
        echo '
        <script>
            $(function() {
                $( "#dialog:ui-dialog" ).dialog( "destroy" );
                $( "#dialog-message" ).dialog({
                    modal: true,
                    buttons: {
                        Ok: function() {
                            $( this ).dialog( "close" );
                        }
                    }
                });
            });
        </script>
        ';
    else { //...  }


<div id="dialog-message" title="Process failed.">
<p><span class="ui-icon ui-icon-circle-check"
    style="float: left; margin: 0 7px 50px 0;"></span> Error message.</p>
</div>

To hide the div use css

#dialog-message{
 display:none;
}

For a better alert there is a nice plugin for Alert, Confirm & Prompt use that plugin
