我正在构建一个基本的表结构，它将有几个隐藏的行，这些行将填充在行下，并使用触发器来切换它们。我似乎无法让我的切换触发器工作。这些行都将基于我们数据库中的数据量在C＃中动态创建。因此，我尝试使用基于计数器的触发器来查找附加到触发器链接的行。任何援助将不胜感激。这是我的代码（P.S.忽略内联样式，这只是我的基础，以使触发器工作，并将在字符串变量中正确地重建它。）：

将您的javascript更改为：
$(document).ready(function(){
function assignClickHandlerFor(boxNum) {
console.log('#a' + boxNum);
$('#a' + boxNum).click(function (evt) {
evt.preventDefault();
evt.stopPropagation();
$('table').find('.rpt28_row' + boxNum).toggle();
});
}
var i;
for (i = 1; i <= 5; i++) {
assignClickHandlerFor(i);
}
});
问题在于您正在检查链接的祖先。需要检查表的祖先。
答案 1 :(得分：1)
问题出在这一行：
var $aRow = $(evt.currentTarget);
$ aRow找不到$（'。rpt28_row'+ boxNum）元素的任何父元素。所以$ dRow.find（'。rpt28_row'+ boxNum）在dom中找不到。
只需将该行更改为：
var $aRow = $(this).parents('table')
它会起作用
答案 2 :(得分：0)
我相信你使用的是jquery。如果是这样，请尝试使用此代码片段
$('#a' + boxNum).click(function () {
$('.rpt28_row' + boxNum).toggle()
}
文档准备就绪后调用此方法。
