jQuery数据表:更新请求/关于数据表重载的PostData [英] JQuery Datatable : Update request / PostData on Datatable Reload

问题描述

我有一个JS模块中定义的JQuery数据表.而且，在其他地方，我试图借助Datatable的ID选择器重新加载它.在这里，我想传递我遇到麻烦的新请求发布数据.

I have a JQuery Datatable that is defined in a JS Module. And, elsewhere, I'm trying to reload it with the help of Datatable's ID selector. Here, I want to pass in new request post data which I'm having trouble with.

我的尝试:

在模块A中:

$(selectors.Datatable)
    .DataTable({
        bProcessing: true,
        serverSide: true,
        ajax: {
            data: initialPostData,
            url: urls.read,
            method: 'POST'
        },
        columns: [...],
        autoWidth: false,
        searchDelay: 500
    });

在模块B中:

var newPostData = [...];
var dataTableWidget = $(selectors.datatableSelector).DataTable();
dataTableWidget.ajax.params(newPostData);
dataTableWidget.ajax.reload();

我期望 dataTableWidget.ajax.params(newPostData); 应该在ajax请求中发布新数据.但这不是.

I was expecting dataTableWidget.ajax.params(newPostData); should be post new data in the ajax request. But it isn't.

params 不会在这里提供帮助.来自文档:

params is not the one that is going to help here. From documentation:

获取上一次Ajax请求中DataTables提交给服务器的数据

Get the data submitted by DataTables to the server in the last Ajax request

推荐答案

研究了JQuery Datatable的文档后，我发现这是一种解决方法.

After looking into the documentation of JQuery Datatable, I found this as a workaround.

dataTableWidget.settings()[0].ajax.data = newPostData;

dataTableWidget.ajax.reload();
