有一个隐藏的 div，但是当我单击添加孩子按钮时，该 div 显示为 4 列，名为名称性别和出生日期并删除。

我已经在按钮单击 addkid 上动态创建了一个表，现在我想删除包含信息的整行，如果单击名为 (del) 的删除按钮，这怎么可能。整个事情都是在提交时起作用的形式。

$('#myTableData').find('tr').each(function(){
   $(this).remove(); // remove element 
})

使用纯 JavaScript，您可以这样做：

var table = document.getElementById('myTableData');
var trs = table.getElementsByTagName('tr');
var dad = trs[0].parentNode;

for(var i = 0; i < trs.length; i++){
   dad.removeChild(trs[i]);
}
