我已经在 php 中创建了动态按钮。单击特定按钮时，我需要获取该按钮的值。当我们点击按钮时，所有信息都会被提取到表单中。
这是我的按钮点击代码
<?php
function dash()
{
include 'config.php';
$sql = "SELECT roomno FROM roombook";
if($result = mysqli_query($db, $sql))
{
$str = '';
while($row = mysqli_fetch_array($result))
{
// generate array from comma delimited list
$rooms = explode(',', $row['roomno']);
//create the dynamic button and set the value
foreach ( $rooms as $k=>$v )
{
$str .= '<input type="button" onClick="showDiv()" name="btn_'.$k.'" value="'.$v.'" id="btn_'.$k.'"/>';
}
}
return $str;
}
else {
echo "ERROR: Could not able to execute $sql. " . mysqli_error($db);
}
mysqli_close($db);
}
?>
<!Doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>room boking</title>
<link href="css/bootstrap1.min.css" rel="stylesheet">
<link rel="stylesheet" href="css/front.css">
</head>
<body>
<form method="post" action="">
<div class =" row box col-md-4" >
<div style="color:black"><?php echo dash();?></div>
</div>
</form>
这里获取表单代码中的值
<!DOCTYPE html>

最佳答案
你可以这样创建你的按钮
$str .= '<input type="button" onClick="showDiv()" data-atribute-id="valueyouwant" name="btn_'.$k.'" value="'.$v.'" id="btn_'.$k.'"/>';
脚本应该是这样的
$("button").click(function() {
alert(this.id); OR
alert($(this).attr('id')); OR
alert($(this).attr('data')); OR
var btnid = $(this).attr('data');//which give you current clicked btn id
});
