Question

我有一个动态生成的表，每次刷新页面时都会插入一行新数据。我如何限制表格，它只显示最多7个表格行，一旦达到7个表格，用数据更新表格现有表格行而不是添加新行。我的应用程序包括前端的thymeleaf，后端的java / springboot。

我正在使用此脚本的百里香叶自动生成我的代码。

Answer 1

您需要为您的数据实现名为pagination的名称。您可能有兴趣查看Thymeleaf Spring Data Dialect。

Answer 2

当您的页面正在刷新并且您不想跟踪最大行时，您可以使用localStorage

var max = 5;
var currentRowsCount = localStorage.get('rowsInsreted') || 0;
if(currentRowsCount < max){
  // insert new row 
  localStorage.setItem("rowsInsreted", currentRowsCount+1));
}
