javascript - 重新加载数据表jquery时处理指示器不起作用

Question

我正在自定义数据表的加载指示器（使用微调器自定义 - startLoadGlobal (SPINNER_DATA_TABLE_FINANCEIRO_CARREGAR_REGISTROS)）jquery 在我第一次加载数据表时可以正常工作。当我重新加载数据表时，微调器不再工作，因为数据表似乎没有触发处理机制。就我而言，“处理”参数应始终设置为 false，以免妨碍自定义。

有谁知道如何帮助我？

谢谢 ：）

数据表：

function load_dtFinanceiroIndex() {
    var table = $("#dtFinanceiroIndex").DataTable({

        "ordering": true, //Ativar/Desativar Ordenação de colunas

微调器-JS：

function startLoadGlobal(text) {
    if (text === '')
        text = "Carregando...";
    
    $("#spinner-global").text(text);
    $("#spinner-global").show();
}

function stopLoadGlobal() {
    $("#spinner-global").text('Carregando...');
    $("#spinner-global").hide();
}

重新加载数据表：

$("#btn-pesquisar-painel-financeiro").on("click", function (e) {
   $('#dtFinanceiroIndex').DataTable().ajax.reload();

根据数据表论坛的帮助，我设法通过验证数据表事件“processing.dt”来解决问题：https ://datatables.net/forums/discussion/39641/processing-events 。

解决方案：

table.on('processing.dt', function (e, settings, processing) {       
    if (processing) {
        startLoadGlobal(SPINNER_PESQUISANDO_REGISTROS);
    } else {
        stopLoadGlobal();
    }
});
