    只是一个愚蠢的回答,希望我能理解你的要求

    你为什么不改变一下

    for (var i = 0; trs.length > i; i++) {
        trs[i].onclick = new Function("rowOnclick(this)");
    }
    

    for (var i = 1; trs.length > i; i++) {
            trs[i].onclick = new Function("rowOnclick(this)");
        }
    

    ?

    从1开始循环应该从第二行分配onClick函数,避免将其绑定到第一行

    编辑:

    我已经使用提供的HTML测试了这个脚本,它似乎可以工作。 单击复选框不会启动重定向,而单击其他列则会启动重定向

    在你的页面上测试一下,让我知道
