我不确定这是否可行，或者我是否以错误的方式进行操作？
我有一个表单提交时，应该发送给用户到一个URL取决于输入。
例如，如果用户输入'2'，则URL应该是 books / itemView？id = 2
我创建了一个 var = id ，它接受搜索输入框的数据。是否有可能将此变量添加到我当前的表单操作？也许有更有效的方法吗？
我现在的代码如下;
< form id =searchaction =<？php echo URL;？> books / itemView？id =method =post> < input type =textname =searchid =demo/> < input type =submitvalue =提交> < / form>我的JS
< code $ $（document）.ready（function（）{ var id = $（'＃search'）。val（）; }）;对于JS来说很新，所以对它有所帮助。
JS应该是 $（'＃search'）。on 'submit'，function（）{ var id = $（'＃demo'）。val（）; var formAction = $（'＃search'）。attr（'action'）; $（'＃search'）。attr（'action'，formAction + id）; }）;
I'm not sure if this is possible, or if I am doing it the wrong way?
I have a form that when submitted, should send the user to a URL depending on the input.
e.g If the users inputs '2', the URL should be books/itemView?id=2
I have created a var = id, which takes the search input box data. Is it possible to add this variable to my current form action? Perhaps there is a more efficient way?
My current code is as follows;
<form id="search" action="<?php echo URL; ?>books/itemView?id=" method="post"> <input type="text" name="search" id="demo"/> <input type="submit" value="Submit"> </form>My JS
$(document).ready(function(){ var id = $('#search').val(); });Quite new to JS so any help appreciated.
解决方案JS should be
$('#search').on('submit', function() { var id = $('#demo').val(); var formAction = $('#search').attr('action'); $('#search').attr('action', formAction + id); });
