测试代码如下
1 <?php 2 echo ‘<meta name="viewport" content="width=device-width,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no">‘; 3 if(!empty($_POST)){ 4 echo "<pre>"; 5 print_r($_POST); 6 exit; 7 } 8 if(!empty($_GET)){ 9 echo "<pre>";10 print_r($_GET);11 exit;12 }13 ?>14 15 <!DOCTYPE html>16 <html>17 <head>18 <title>DEMO</title>19 <meta charset="UTF-8" />20 <meta name="viewport" content="width=device-width,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no">21 </head>22 <body>23 <a href="http://mall.aili88.cn/demo.php?id=54" target="_blank">带target=_blank的超链接</a>24 <h3>带target=_blank的表单</h3>25 <form action="http://mall.aili88.cn/demo.php" method="post" target="_blank">26 用户名:<input type="text" name="uname"/><br/>27 <button type="submit">提交</button>28 </form>29 <h3>带target=_self的表单</h3>30 <form action="http://mall.aili88.cn/demo.php" method="post" target="_self">31 用户名:<input type="text" name="uname"/><br/>32 <button type="submit">提交</button>33 </form>34 <h3>带target=_parent的表单</h3>35 <form action="http://mall.aili88.cn/demo.php" method="post" target="_parent">36 用户名:<input type="text" name="uname"/><br/>37 <button type="submit">提交</button>38 </form>39 <h3>带target=_top的表单</h3>40 <form action="http://mall.aili88.cn/demo.php" method="post" target="_top">41 用户名:<input type="text" name="uname"/><br/>42 <button type="submit">提交</button>43 </form>44 <h3>不带target的表单</h3>45 <form action="http://mall.aili88.cn/demo.php" method="post">46 用户名:<input type="text" name="uname"/><br/>47 <button type="submit">提交</button>48 </form>49 </body>50 </html>
"带target=_blank的表单"提交无效
前提条件：
1. IOS
2. 微信浏览器（也有可能和微信版本有关，当时我测试的版本是6.5.8）
微信web开发工具（v0.7.0）满足上述2个条件，测试结果如下
