答案 0 :(得分:2)
我认为你有两个错误,它们都与调用after()无关。
您的正则表达式有语法错误。而不是[w-.]
,而是[w.-]
。
你把生日的变量名称混淆了:一个地方的月,日,年在另一个地方,月,日,年。
如果我修复了这些内容,那么点击提交按钮就可以为我提供我认为你打算做的事情。
答案 1 :(得分:1)
在插入元素后尝试制作,而不仅仅是一串文字:
$("#mon").after('<p>Please enter your birthday</p>');
答案 2 :(得分:1)
我不确定,代码很大......但我认为你不应该为点击按钮asoc一个事件处理程序。您应该将处理程序添加到表单提交。
$("form").submit(
function (e){
....
}
);
答案 3 :(得分:0)
我只想使用一个显示所有错误的div。此外,文档说HTML字符串。你试过一些段落标签吗?我知道这不值得,但值得一试。你能详细说明你得到的结果吗?
