如何在js中使用按钮获取while循环中的值？

def connect(p_str, autocommit=False, ansi=False, timeout=0, **kwargs): # real signature unknown; restored from __doc__
    """
    connect(str, autocommit=False, ansi=False, timeout=0, **kwargs) --> Connection

    Accepts an ODBC connection string and returns a new Connection object.

    **The connection string will be passed to SQLDriverConnect, so a DSN connection
    can be created using:**

      **cnxn = pyodbc.connect('DSN=DataSourceName;UID=user;PWD=password')**

    To connect without requiring a DSN, specify the driver and connection
    information:

      DRIVER={SQL Server};SERVER=localhost;DATABASE=testdb;UID=user;PWD=password

    Note the use of braces when a value contains spaces.  Refer to SQLDriverConnect
    documentation or the documentation of your ODBC driver for details.

    The connection string can be passed as the string `str`, as a list of keywords,
    or a combination of the two.  Any keywords except autocommit, ansi, and timeout
    (see below) are simply added to the connection string.

      connect('server=localhost;user=me')
      connect(server='localhost', user='me')
      connect('server=localhost', user='me')

    The DB API recommends the keywords 'user', 'password', and 'host', but these
    are not valid ODBC keywords, so these will be converted to 'uid', 'pwd', and
    'server'.

    pass

谢谢

Answer 1

单击按钮可以获得文本框的值。

<input type="text" name="sample[]" value="abc" class="valueInput">
<input type="text" name="sample[]" value="xyz" class="valueInput">
<input type="text" name="sample[]" value="pqr" class="valueInput">
<input type="button" class="getValue" value="Get Value">

注意：我已经设置了静态输入框，可以将其设为动态，但请确保将类添加为valueInput。

jQuery代码。

$(document).on('click','.getValue',function(){
var valArr = [];
$(".valueInput").each(function(){
    valArr.push($(this).val());
});
console.log(valArr);
})

输入字段的名称应使用[]表示一个数组。

<form action="action.php" method="POST">
<?php
    while ($row = mysqli_fetch_array($query)){
       echo '<input type="text" name="sample[]" value="'.$row['sample'].'">';
    } 
?><input type="submit">
</form>

action.php ：（处理提交时的数据）

<?php
      echo "<pre>";
      print_r($_POST['sample']);
      echo "</pre>";
