【问题描述】:
我想通过 select2 插件使用 MySQL 远程数据作为标签。但是我对 JSON 的学习曲线非常薄弱。请帮我纠正这种 JSON 格式。
$("#e7").select2({
placeholder: "Search for a movie",
minimumInputLength: 3,
ajax: {
url: "search.php",
dataType: 'jsonp',
quietMillis: 100,
data: function (term, page) { // page is the one-based page number tracked by Select2
return {
q: term, //search term
page_limit: 10, // page size
page: page, // page number
apikey: "ju6z9mjyajq2djue3gbvv26t" // please do not use so this example keeps working
};
},
results: function (data, page) {
var more = (page * 10) < data.total; // whether or not there are more results available
// notice we return the value of more so Select2 knows if more results can be loaded
return {
results: data.movies,
more: more
};
}
},
formatResult: movieFormatResult, // omitted for brevity, see the source of this page
formatSelection: movieFormatSelection, // omitted for brevity, see the source of this page
dropdownCssClass: "bigdrop", // apply css that makes the dropdown taller
escapeMarkup: function (m) {
return m;
} // we do not want to escape markup since we are displaying html in results
});
这里是search.php
<?php
$sql=mysqli_query($db3->connection,"SELECT * FROM tags");
while($row=mysqli_fetch_array($sql)){
$tags=$row['tags'];
$id=$row['id'];
$response=array();
$response['tags']=$tags;
$response['id']=$id;
}
echo json_encode($response);
?>

-
如果您不解释问题是什么,即您期望发生什么、实际发生什么、您收到什么错误消息等,那么我们不太可能提供帮助你。请编辑您的问题并详细说明问题。不,“它不工作”不是一个有用的错误描述。我的烤面包机也不工作。
-
您在 while 循环中重置 $response。将
$response=array();移到外面并用$response[]=array('tags'=>$tags, 'id'=>$id);替换里面
