How to Prevent refresh When DB failed

[zhang]

Here is my example code(Delete):

destroy: {
type: 'post',
url: base_url + "delete",
dataType: "json",
contentType: 'application/json; charset=utf-8',

complete: function (jqXhr, data) {

if (jqXhr.responseJSON.success) {
}
else {
}

alert(jqXhr.responseJSON.msg)

console.log(jqXhr, data)

return false;

}

My response json : {"id":null,"success":false,"msg":"操作失败！","response":null}

 

PLS help.

Hello Zhang,

The correct way for handling request errors is within the "error" event of the DataSource:

• https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/events/error

As for preventing the refresh of the Grid, preventing the dataBinding event should do the trick:

function error(args) {
        if (args.errors) {
            var grid = $("#grid").data("kendoGrid");
            grid.one("dataBinding", function (e) {
                e.preventDefault();   // cancel grid rebind if error occurs

            });
        }
    }

Hope this helps.
