.done（）jQuery无法正常工作

Question

Im using the below code for a ajax call

var getRequest = $.ajax({
    type: 'GET',
    url: Url,
    async: false,
    dataType: "text",
    complete: function () {
        $('#loading').hide();
    }
});

the request is getting complete and data is also withdrawn after the data is recieved the following:

getRequest.done(function (dataDb) {
    if (dataDb) {
        alert('dataDb: ' + dataDb);

    }
});

getRequest.fail(function (jqXHR, textStatus, error) {
    alert('data error within getUsersRequest ' + textStatus + ' : ' + error);
});

I'm recieving a error that getRequest.done(function(dataDb) or getRequest.fail(function(jqXHR, textStatus, error) is not a function.

It is because your JQuery version is too old.

You can use success if you are not willing to upgrade the latest version of JQuery.

success: function(dataDb) {

    }
