数据表状态保存多个输入答案

【问题标题】：Datatables State Save Multiple Inputs数据表状态保存多个输入
【发布时间】：2017-11-30 14:41:57
【问题描述】：

使用Datatables v1.10.16。

我正在尝试使用state save 功能。我想在输入中输入值，重新加载页面，并让输入保留值并且表格保持过滤状态。

目前表格过滤良好，状态保存似乎工作了一半 - 从某种意义上说，如果我过滤表格并重新加载页面，表格仍然被过滤。试试下面的小提琴链接，过滤表格然后重新加载页面 - 输入值消失。

如何让输入显示页面重新加载时最后输入的值？

【解决方案1】：

您只需要处理 stateSaveParams 和 stateLoadParams 回调。他们传递了一个 data 对象文字，您将自定义值添加到：

stateSaveParams: function( settings, data ) {
  data.searchName = $('#searchName').val()
  data.searchLang = $('#searchLang').val()
  data.yearMin = $('#yearMin').val()
  data.yearMax = $('#yearMax').val()
},
stateLoadParams: function( settings, data ) {
  $('#searchName').val(data.searchName)
  $('#searchLang').val(data.searchLang)
  $('#yearMin').val(data.yearMin)
  $('#yearMax').val(data.yearMax)
}

通过点击运行尝试搜索/过滤和更新以刷新页面。

这太完美了，谢谢！知道为什么当我从name 输入选项卡到language 输入时，表会重置为默认值？抱歉，这是一个单独的问题！
因为你使用的是keyup，并且只搜索当前字段的值。当您进入空的#searchLang 时，输入$('#searchLang').keyup(function() { 被触发为空值，因此所有行都被选中。您可以使用一种方法来设置/更新所有 4 个输入的过滤器，然后从 4 个 keyup 处理程序中调用该方法。
