当我这样做时，我一直收到这个错误：
<?php
$info = $_POST['mname'];
$info = ucwords($info);
// Make a MySQL Connection
mysql_connect("localhost", "user", "password") or die(mysql_error());
mysql_select_db("javadatest") or die(mysql_error());
// Get a specific result from the "example" table
$result = mysql_query("SELECT * FROM movieList
WHERE name = '$info'") or die(mysql_error());
// get the first (and hopefully only) entry from the result
$row = mysql_fetch_array( $result );
// Print out the contents of each row into a table
//echo $row['name']." ".$row['year']." ".$row['genre'];
echo "
<script language=javascript>
var jsvar;
jsvar = <?php echo $row['name'], $row['year'], $row['genre'];?>
function buy() {
window.location = '"https://www.paypal.com'";
alert('"Thanks for shopping at Movie Store'");
}
var myWindow = window.open('', '', 'width = 300, height = 300);
myWindow.document.write(jsvar);
myWindow.document.write('<body>');
myWindow.document.write('<input type="button" value="Buy" onclick=/"buy()/">');
myWindow.document.write('</body>');
//myWindow.buy = buy;
</script>
";
?>
我试图通过将javascript代码放在echo语句中，在php文件中使用javascript。我不明白我做错了什么。如有任何帮助，我们将不胜感激。
您不需要编写这行
jsvar = <?php echo $row['name'], $row['year'], $row['genre'];?>
只需使用
jsvar = {$row['name']} {$row['year']} {$row['genre']};
因为您已经使用了PHP。
还有
更换
myWindow.document.write('<input type="button" value="Buy" onclick=/"buy()/">');
带有
myWindow.document.write('<input type='"button'" value='"Buy'" onclick='"buy()'">');
myWindow.document.write('<input type="button" value="Buy" onclick=/"buy()/">');
应该是
myWindow.document.write('"<input type='button' value='Buy' onclick='buy()'>'");
$row = mysql_fetch_array( $result );
// Print out the contents of each row into a table
//echo $row['name']." ".$row['year']." ".$row['genre'];
?>
<script language=javascript>
var jsvar;
jsvar = <?php echo json_encode($row['name']), json_encode($row['year']), json_encode($row['genre']);?>
function buy() {
window.location = '"https://www.paypal.com'";
alert('"Thanks for shopping at Movie Store'");
}
...
