?>

我需要在$ receipt结果集上面加载以下availableTags .... plz帮助我

如果javascript在php页面内,请尝试此操作:

<script>
$(function() {
var availableTags = [
<?php foreach($receipt AS $r=>$value){
echo '"'.$value.'"';
if($r != count($receipt)-1) { echo ", ".PHP_EOL; }
}?>

];
</script>

你的意思是:

<?php

$book_no2 = $load_book["book_no"];
$query    = "SELECT DISTINCT receipt_no 
             FROM scheme_master 
             WHERE book_no2 = :book_no2";
$receipt  = $database->getRows($query, array(':book_no2' => $book_no2));  

// create tag list
$tags = '';
foreach ($receipt AS $row) {
$tags .= '"'.$row->receipt_no.'",'.PHP_EOL;
}
$tags = substr($tags,0,-2);

// write javascript
echo "<script>
$(function() {
var availableTags = [
$tags
];
</script>";

?>

您可以创建一个外部PHP文件并将其调用到jQuery ajax函数。所以你可以得到那些标签

例如

$.ajax({
    type: 'GET',
    url: 'tags.php',
    success: function(data) {
        var exploded = data.split("|");                     
        ...
    }
}); 

在php文件中

<?php
$book_no2 = $load_book["book_no"];
$receipt = $database->getRows("SELECT DISTINCT receipt_no FROM scheme_master WHERE book_no2 = :book_no2", array(':book_no2'=>$book_no2));  
$output = '';
foreach($receipt as $rec){
    $output .= $receipt->receipt_no.'|';  // Since I'm not familiar with PDO SQL, I'm not sure of this syntax
}
echo $output
?>

这是一个非常粗略的例子,还有许多其他方法来处理数据。例如,我更喜欢使用JSON,我使用json_encode函数来回显PHP中的数据。使用jsonparse函数从jquery读取它。

希望有所帮助
