我在基于jQuery / JSON的实时搜索中坚持这个问题好几天我正在建立一个在线商店。使用Tipue Drop开源我可以在使用他们的测试JSON时获得结果，但似乎无法让它读取我的。我有一个JSON文件here，并使用下面的javascript尝试使用Tipue Drop读取名称和描述字段。关于如何解决这个问题的任何建议都表示赞赏！

这会导致tipuedrop在遍历页面时失败，并停止处理脚本的其余部分（因为您专门查看名称和描述属性）。
如果您的PHP页面从JSON文件中提取JSON，您可以使用它来静态修改JSON文件以修复它：
<?php
$json = json_decode(file_get_contents('json.json'));
foreach($json->pages as &$page){
if(!isset($page->description)){
$page->description = "";
}
if(!isset($page->name)){
$page->name = "";
}
}
file_put_contents('json.json', json_encode($json));
?>
或者，如果您的PHP页面将信息提取到其他位置（txt文件或数据库或其他内容），您可以将其更改为动态添加描述＆amp;为每个没有该组的元素命名（它的代码大致相同，只是稍微修改一下），并回显动态更改的代码。

我解决错误的一种方法是在尝试获取其偏移量之前检查jQuery对象是否包含任何元素：
示例：
var nav = $('.content-nav');
if (nav.length) {
var contentNav = nav.offset().top;
...continue to set up the menu
}
