javascript - 在js字符串里嵌入php代码,添加到页面被注释掉
需要从后台数据库取值的,在select标签遍历数据库里面的数据
<code><?php $_link=mysql_connect("localhost","root",""); mysql_query("SET NAMES UTF8"); mysql_select_db("store"); $_result= mysql_query("select goods_no,goods_name,goods_qu from stock_goods"); ?> <select> <option value="#">选择商品编号</option> <?php while(!!$_rows=mysql_fetch_array($_result,MYSQL_ASSOC)){ ?> <option value="<?php echo $_rows[goods_name]?>"> <?php echo $_rows[goods_no];?> </option> <?php } ?> </select></code>
默认的select标签只有一个
点击下面的加号后要在添加一行数据
问题来了!!!这里使用js代码定义一个字符串,然后使用JQ的append添加到节点,生成一条数据表格,可是这时候的select标签要怎么遍历数据库,把php代码写到js的字符串里面,添加进页面之后就被注释掉了,不起作用。
所以最佳的解决方法是什么?!!

试下我没测试
<code><?php while(!!$_rows=mysql_fetch_array($_result,MYSQL_ASSOC)){ ?> <select> <option value="#">选择商品编号</option> <option value="<?php echo $_rows[goods_name]?>"> <?php echo $_rows[goods_no];?> </option> </select><?php } ?> </code>
下面是我写的:
<code> <?php $rooms = GetDesks(); ?> <?php if($rooms):?> <form id="options"> <div class="order-info-item"> <p><?php echo $shop['deskname'];?></p> <div class="item-value"> <div class="select-outer item-value-selectposition"> <div class="select-arrow"></div> <select name="field[1][content]"> <?php $flag=true; foreach ($rooms as $k => $v) { echo '<option value="'.$v['id'].'">' . $v['title'] . '</option>' . "\n"; $flag=false; }?> </select> </div> </div> </div> </form> <?php endif?> </code>
你这写法太神奇了, js又不认识php标签, 当然不能了...
当然, 你要是把代码直接放在php文件里, 用script标签包起来也是可以的, 但是绝对不能放到js文件里去...
理想的做法是用php将数据已json的格式输出的页面, 然后js解析json,拼接代码

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3.
