Question

有没有办法使用MYSQL从数据库获取数据并将其存储在javascript数组中？

Answer 1

<?php
$arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5); 
// of course this array can be created by looping through your mysql result set
// and doing a mysql_fetch_assoc
// for example, $sql = your query here 
// mysql_fetch_assoc($result); etc

echo json_encode($arr);
?>

{"a":1,"b":2,"c":3,"d":4,"e":5}

然后你可以做类似

的事情

<script type="text/javsacript">
var abc = "<? echo json_encode($arr);?>";
</script>

OR

echo '<script type="text/javsacript">
        var abc ="'.json_encode($arr).'";
    </script>';

Answer 2

将其作为associative array获取，然后使用json_encode创建一个存储在字符串中的JavaScript数组。

Answer 3

// first, build your query:
$sql = "SELECT name, email FROM users";

$result = mysql_query($sql);

// then build up your data
$rows = array();

while ($row = mysql_fetch_assoc($result)) {
    $rows[] = $row;
}

//then write it in a way Javascript can understand:

echo "<script type=\"text/javascript\">\n"
    . "var users = " . json_encode($rows) . ";\n"
    . "</script>";

实际上这是一个非常含糊的问题，但我认为AJAX正是你所期待的对于。

编辑：当然JSON也会锻炼，甚至可能更直接......
