javascript - kendo-ui grid problem, I want to change the path of the URL before requesting, is there any way?

Question

    var mainGridDataSource = new kendo.data.DataSource({
        type: 'aspnetmvc-ajax',
        transport: {
            read: {
                url: "/test",
                contentType: "application/json",
                type: "POST"
            },
            parameterMap: function (options, operation) {
                return JSON.stringify(options);
            }
        }
    });

Now when entering the page, the data of this URL is requested by default. I want to change the path of the URL after the change() event. What should I do?
I tried the following method, but it didn’t work.

                   
mainGridOptions.dataSource.transport.read({
  url: "/test2"
});

Answer 1

function getData(opts, callback){
    return new kendo.data.DataSource({
        type: 'aspnetmvc-ajax',
        transport: {
            read: opts,
            parameterMap: function (options, operation) {
                typeof callback == 'function' && callback(options, operation);
            }
        }
    });
}

Write the request into a method, and pass the url and contentType in as attributes of an object. The business processing after the request is successful is also handled with a callback function. Just execute this method after the change event
