有时前台页面要允许动态增加/删除某项属性的多个值,比如向书架中添加书本,要可以动态增加或者删除书本。前台页面的表单中会有多个input元素,如下:

代码如下:








当a.php页面收到表单数据时,可以利用$books = $_REQUEST['books'];得到所有书名的数组。
PHP CI 中通过post过来的数据获取方式:$books = $this->input->post('books');//注意这里是books,表单name里面是数组形式的books[]

js 获得多个同name 的input输入框的值

var els =document.getElementsByName("books");
for (var i = 0, j = els.length; i < j; i++){
alert(els[i].value);
}
Copy after login
