在下面，您可以看到我正在进行一个简单的ajax调用。但是，在调用成功完成之后，我想从页面中删除loader div。问题是成功函数不触发，为什么？

utils.get_do stuff = function AJAX_do stuff() {
    $.getJSON('/url//',
        function (data) {
            $.each(data, function (key, val) {
                // I do stuff with the data here.
            });
        },
        function (success) {
            $('#loader').hide();
        }
    );
};

最佳答案

这是getJSON的示例，我认为您必须在完整的处理程序中隐藏$('#loader')，因此无论请求失败还是成功，$('#loader')都会隐藏。

 $.getJSON( "/sms/fetch_smartpages/", function() {
    console.log( "success" );
        $.each(data, function (key, val) {
         //I do stuff with the data here.
        });
        $('#loader').hide(); //<==== moved from here
    })
    .done(function() { console.log( "second success" ); })
    .fail(function() { console.log( "error" ); })
    .always(function() {
                console.log( "complete" );
                $('#loader').hide(); // moved here
     });
