我使用光滑网格进行数据显示。我有删除按钮，用于从光滑网格和服务器中删除已检查的行。当我选择行后点击删除按钮。成功删除行，但整个单击事件函数执行多次。它再次检查所选行的长度n显示警告“选择至少一行！”。反复。我无法辨认这个错误。如果有人请帮助我。

听起来你的事件处理程序不止一次受到约束。由于您正在使用直播活动，我猜测必须动态添加删除按钮？如果是这样，那可能就是问题 - 每次将删除按钮添加到页面时，新的事件处理程序就会绑定到它。而不是现场活动试试这个：

$('div.left_section').unbind('click').on('click', '#bulk_delete_id', function(e) {
   // event handler code goes here

使用slickgrid复选框列从服务器和网格中删除多个数据
