Handling Errors

[Hostilio]

Hello, i need help with the following:

1. How to Handle error when the ASMX webservice doesn't exists anymore cause for example it was moved, name changed
2. How to handle a timeout error.
3. How to handle any error example, webservice could have a error for example division by 0 and not handle it a try catch

At my different test escenarios none of those escenarios runs .done code.

I'm trying to use ej.DataManager with knockoutjs, require, bootstrap :) and with the following code i can call the ASMX webservice and read the data fine as long as there are no communication error.

 var dataManager = ej.DataManager({
                url: "/Datos.asmx/CatalogoIncidente",
                adaptor:new ej.UrlAdaptor(), //"UrlAdaptor",
                crossDomain: false,
                offline: false
            });
            var query = ej.Query();
            query.addParams("userName", "EB_HMACIAS");
            var promise = dataManager.executeQuery(query);
            promise.done(function (e) {
                ko.mapping.fromJSON(e.result, {}, self);
            });

Thanks for response

Hi Hostilio,

Thanks for contacting Syncfusion support.

We can handle the error or any exception in the fail function. The fail function gets invoked when there is any error while making the request or an exception.

For your convenience, we have created a sample and thrown an exception manually in the ASMXPage.

Please find the following code example and sample:

<script type="text/javascript">

       

        var dataManager = ej.DataManager({

            url: "/WebService.asmx/Get",

            adaptor: new ej.UrlAdaptor(), //"UrlAdaptor",

            crossDomain: false,

            offline: false

        });

        var data = [];

        var query = ej.Query();

        query.addParams("userName", "EB_HMACIAS");

        var promise = dataManager.executeQuery(query);

        promise.done(function (e) {

            data = e.result.result;

        });

        promise.fail(function (e) {

            alert("Handling errors")

        });     
    </script>
