  1. <

    script type="text/javascript">

    $(

    function() {

    $(

    "#Business_Address").autocomplete({

    source:

    function(request, response) {

    $.ajax({

    url:

    "Get",

    focus:

    function(event, ui) {

    $(

    "#Business_Address").val(ui.label);

    return false;

    },

    select:

    function( event, ui ) {

    $(

    "#Business_Address").val(ui.item.label);

    return false;

    },

    success:

    function(data) {

    if (data == null)

    { alert(

    "nothing"); }

    else {

    response(data)

    }

    }

    });

    }

    })

    .data(

    "autocomplete")._renderItem = function(ul, item) {

    return $( "<li></li>" )

    .data(

    "item.autocomplete", item )

    .append(

    "<a>" + item.Label )

    .appendTo( ul );

    };

    });
