是否存在可以在ajax请求中调用成功和错误回调函数的情况？

Question

In below pseudo-code the error a redirect is occurring even though the error callback is being invoked. The success callback should not be called if the error call back is called ?

$.ajax({

success : {

redirectPage();
}

error : {

}

Answer 1

Either the success callback is called, or the error one, but not the both at the same ajax request.

That said, if you need to fake this behavior, here could be a solution:

// first solution

$.ajax({
    complete: function() {
        alert("complete() called...");
    }
};

// second solution

function success() {
    alert("success() called...");
}

$.ajax({
    success: success,
    error: function() {
        success();
        // any additional code
    }
};
