实现如下&＃xff1a;可以点击delete删除信息&＃xff0c;并且可以通过添加新员工功能可以把新员工加到上一个表格中。
其中&＃xff0c;css代码如下&＃xff1a;
&＃64;CHARSET "UTF-8";
#total {width: 450px;margin-left: auto;margin-right: auto;
}ul {list-style-type: none;
}li {border-style: solid;border-width: 1px;padding: 5px;margin: 5px;background-color: #99ff99;float: left;
}.inner {width: 400px;border-style: solid;border-width: 1px;margin: 10px;padding: 10px;float: left;
}#employeeTable {border-spacing: 1px;background-color: black;margin: 80px auto 10px auto;
}th,td {background-color: white;
}#formDiv {width: 250px;border-style: solid;border-width: 1px;margin: 50px auto 10px auto;padding: 10px;
}#formDiv input {width: 100%;
}.word {width: 40px;
}.inp {width: 200px;
}
Javascript代码和html结构如下&＃xff1a;
