使用ASP.NET MVC Ajax调用的全局"加载"通知

<div id="global-loading" style="display:none;">
    <img src="path/to/loading-image.gif" alt="Loading..." />
</div>

$(document).ajaxStart(function() {
    $("#global-loading").show();
});

$(document).ajaxStop(function() {
    $("#global-loading").hide();
});

$.ajax({
    url: "your/url/here",
    type: "GET",
    beforeSend: function() {
        $("#global-loading").show();
    },
    success: function(data) {
        // Handle your success case here
        $("#global-loading").hide();
    },
    error: function(xhr, status, error) {
        // Handle your error case here
        $("#global-loading").hide();
    }
});
