我有一个动态创建的表。哪个工作得很好。我想采用概述的 php 函数，它在每个单元格中创建按钮（按钮不起作用但确实显示）并使用 javascript 或其他类似语言。我的最终目标是当用户单击按钮时会弹出一个框，用户可以在其中做出选择并提交，就像在 php 函数中一样。我对 javascript 没有太多经验，老实说，我找不到任何关于如何做到这一点的信息。

下面是我的 php 文件。

 <?php 
 session_start();
 $tbvbr= $_SESSION['gamecode'];


 //user can only edit the row they created

 $_GET["editmode"]=$_SESSION['playername'];

//start creating the table
 function stripslashes2( $string ) 
 { 
 if ( get_magic_quotes_gpc() ) { 
    return stripslashes( $string ); 
} else { 
    return $string; 
}  
}  

function display_db_query( $tablename, $header_bool , $border ) 
{  
// find out the number of columns in result 
$result = mysql_query( "SHOW FIELDS FROM $tablename" ); 
while ( $row = mysql_fetch_assoc( $result ) ) { 
    if ( $row['Key'] == "PRI" ) 
        $primarykey = $row['Field']; 
    else 
        $field[$row['Field']] = array( $row['Type'] ); 
  }  

    if ( isset( $_POST["update$tablename"] ) ) { 
    $sql = sprintf( "update $tablename SET " ); 
    $sqlfields = array(); 

    foreach( $field AS $k => $v ) { 
        if ( !empty( $_POST["edit"][$k] ) ) 
            $sqlfields[] = "$k='" . mysql_real_escape_string( stripslashes2(    $_POST["edit"][$k] ) ) . "'"; 
        else 
            $sqlfields[] = "$k = NULL "; 
    }  
    if ( count( $sqlfields ) > 0 ) { 
        $sql .= implode( " , " , $sqlfields ) . " WHERE $primarykey=" . intval( $_POST["updateid"] ) ; 

    mysql_query( $sql ) OR DIE( mysql_error() ); 
    if ( mysql_affected_rows() > 0 ) 
        print "Updated succesfully<br />"; 
    }  
    else 
    echo "No change<br />"; 
}  
// perform the database query 
$result_id = mysql_query( "SELECT * from $tablename" ) 
or die( "display_db_query:" . mysql_error() ); 

  if ( $header_bool ) { 
    echo "<table width='850' $border align='center' cellpadding='5' cellspacing='1'  class='entryTable'>"; 
    echo "<tr class='entryTableHeader'>"; 
    foreach( $field AS $k => $v ) 
    print( "<td><center><b>$k</b></center></td>" ); 


    } else 
    echo "<table width='850' $border align='center' cellpadding='5' cellspacing='1' class='entryTable'> "; 

while ( $row = mysql_fetch_assoc( $result_id ) ) { 
    print( "<tr>" ); 
    // can edit only edit their row
    if ( $_GET["editmode"] AND $_GET["editmode"] == $row[$primarykey] ) { 
        $editmodeison = true; 
        echo "<form method=\"post\" action=\"{$_SERVER["PHP_SELF"]}\">"; 

        // this keeps users from editing other users rows
    } else 
        $editmodeison = false; 

    foreach( $field AS $k => $v ) { 

        if ($editmodeison) 
                         print( "<td class='content' align='center'><input type=\"button\" name=\"edit[$k]\"  value=\"" . ( !empty( $row[$k] )?htmlspecialchars( $row[$k] ) : htmlspecialchars( '' ) ) . "\" /></td>\n" ); 

        else 
            print( "<td class='content' align='center'>" . ( !empty( $row[$k] )?htmlspecialchars( $row[$k] ) : htmlspecialchars( 'change' ) ) . "</td>\n" ); 
    }  

    if ( $editmodeison ) 
        print( "<td class='content' align='center'><input type=\"hidden\" name=\"updateid\" value=\"{$row[$primarykey]}\"><input type=\"submit\" name=\"update$tablename\" value=\"update\"></form></td>\n" ); 
    else 

        print( "<td class='content' align='center'><a href=\"{$_SERVER["PHP_SELF"]}?editmode=" . $row[$primarykey] . "\">change</a></td>\n" ); 
    print( "</tr>\n" ); 
}  
print( "</table>\n" ); 
}  

?> 
<HTML><HEAD><TITLE>Products Orderable table</TITLE></HEAD> 
<BODY> 
<TABLE><TR><TD> 
<?php 

 /* For the following details, ask your server vendor  */ 
 $dbhost = "localhost"; 
 $dbuser = "placeholder"; 
 $dbpass = "placeholder"; 
 $dbname = "placeholder"; 
 mysql_connect( $dbhost, $dbuser, $dbpass ) or die ( "Unable to connect to MySQL server" ); 
 mysql_select_db( "$dbname" ); 
 mysql_query( "SET NAMES utf8" ); 

 $table = $tbvbr; 

 display_db_query( $table, // $global_dbh, 
 true, "border='2'" ); 

  ?> 
 </TD></TR></TABLE></BODY></HTML>

这是我试图改变和使用 JavaScript 或其他东西的函数

 if ($editmodeison) 
                         print( "<td class='content' align='center'><input type=\"button\" name=\"edit[$k]\"  value=\"" . ( !empty( $row[$k] )?htmlspecialchars( $row[$k] ) : htmlspecialchars( '' ) ) . "\" /></td>\n" ); 

        else 
            print( "<td class='content' align='center'>" . ( !empty( $row[$k] )?htmlspecialchars( $row[$k] ) : htmlspecialchars( 'change' ) ) . "</td>\n" ); 
    }  

    if ( $editmodeison ) 
        print( "<td class='content' align='center'><input type=\"hidden\" name=\"updateid\" value=\"{$row[$primarykey]}\"><input type=\"submit\" name=\"update$tablename\" value=\"update\"></form></td>\n" ); 
    else 

        print( "<td class='content' align='center'><a href=\"{$_SERVER["PHP_SELF"]}?editmode=" . $row[$primarykey] . "\">change</a></td>\n" );

我必须再次感谢上述帮助我的人。

下面的代码是我的问题的答案。

我编辑的代码

if ($editmodeison) 
                         print( "<td class='content' align='center'><input type=\"button\"onClick=\"reply_click(this.name)\" name=\"edit[$k]\"  value=\"" . ( !empty( $row[$k] )?htmlspecialchars( $row[$k] ) : htmlspecialchars( '' ) ) . "\" /></td>\n" );

当然，我也必须将脚本添加到我的代码中。

  <script src="http://code.jquery.com/jquery-1.9.1.js"></script>

  <script type="text/javascript">
function reply_click(clicked_name)
{
alert(clicked_name);
 }
</script>

再次感谢您为我指明正确的方向！
