Hi All,

I need to validate a field from database to make sure it is not exist.

I've tried using editrules custom and create AJAX function to validate.

Here is my code :

colModel :

{name:'serialNo', key:true, index:'serialNo', editable:true, editrules:{required:true,custom:true,custom_func:check_serialNo}, width:88, align:"center"}

AJAX function :

function check_serialNo( value, colname ) {
    $.ajax({
        url: 'http://localhost/hexing/index......',
        data: { serialNo: value },
        type: 'POST',
        datatype: 'text',
        success: function ( data ) {
            if ( data ) result = [true,""];
            else result = [false,"Serial number is registered"];
        }
    })
    //alert (result);
    return result;
};

When I tried to Submit form, I have to click the button twice. Did I missed something ? I have similiar issue with defaultValue from AJAX.

Can someone enlight me ? Thanks.

Hello,

try to set async: false in ajax.

function check_serialNo( value, colname ) {
    $.ajax({
        url: 'http://localhost/hexing/index&.....te/',
        data: { serialNo: value },

type: 'POST',

        async : false,
        datatype: 'text',
        success: function ( data ) {
            if ( data ) result = [true,""];
            else result = [false,"Serial number is registered"];
        }
    })
    //alert (result);
    return result;
};

Kind Regards
