所以我有这个 jQuery 脚本,它从数据库中获取内容,并且它需要显示产品名称(我的表有productid和productname)。但它不显示产品名称,而是显示产品 ID。我该如何解决这个问题?
这是 jQuery 代码:-
<script>
$(function() {
function log( message ) {
$( "<div>" ).text( message ).prependTo( "#log" );
$( "#log" ).scrollTop( 0 );
}
$( "#birds" ).autocomplete({
source: "search.php",
minLength: 2,
select: function( event, ui ) {
log( ui.item ? "Selected: " + ui.item.actor + " aka " + ui.item.label :
"Nothing selected, input was " + this.actor );
// window.location.href = 'pretravel.php?id=' + ui.item.label;
// document.testForm.action = "pretravel.php?id="+ui.item.value;
//document.testForm.submit();
}
});
});
</script>
这是 search.php
<?php
include 'dbconnector.php';
// Sanitise GET var
if(isset($_GET['term']))
{
$term = mysql_real_escape_string($_GET['term']);
// Add WHERE clause
//$term="Apple";
$query = "SELECT `productid`, `productname` FROM `products` WHERE `productname` LIKE '%".$term."%' ORDER BY `productid`";
$result = mysql_query($query,$db) or die (mysql_error($db));
$id=0;
$return=array();
while($row = mysql_fetch_array($result)){
array_push($return,array('label'=>$row['productid'],'actor'=>$row['productname']));
//array_push($return,array('actor'=>$row['productname'],'label'=>$row['productid']));
}
header('Content-type: application/json');
echo json_encode($return);
//var_dump($return);
exit(); // AJAX call, we don't want anything carrying on here
}
else
{
header('Location:index');
}
?>
欢迎任何建议。
看起来您正在返回一个数组,来自 jQuery API 参考数组类型定义状态
An array of objects with label and value properties
因此,如果您更改
search.php
页面以返回这些类型,它应该可以工作:
while($row = mysql_fetch_array($result))
{
array_push($return,array('value'=>$row['productid'],'label'=>$row['productname']));
}
