<script>
         $(function () {
         var loading = window.document.getElementById("loading_container");
        $(document).ajaxStart(function () {
            //console.log('start-------------')
             loading.innerHTML="<div class=\"ui active inverted dimmer\"> <div class=\"ui text loader\">加载中......</div></div>";
        });
         $(document).ajaxError(function () {
            // console.log('error--------');
            loading.innerHTML='';
        });
        $(document).ajaxStop(function () {
            //console.log('stop----');
            loading.innerHTML='';
        });
    });

</script>
