MrM*_*ado 1 ajax jquery mongoose node.js express
这是HTML:
<!DOCTYPE html>
<html>
<head>
<link rel="shortcut icon" href="/favbar.png" />
<!-- JavaScript -->
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.1/themes/base/jquery-ui.css" />
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.1/jquery-ui.js"></script>
<script type="text/javascript">
$(function () {
$("#search").autocomplete({
source: function( request, response ) {
$.ajax({
url: "/search",
dataType: "jsonp",
data: {
featureClass: "P",
style: "full",
maxRows: 12,
term: request.term
},
success: function( data ) {
response( $.map( data.results, function( item ) {
return {
label: item,
value: item
}
}));
}
});
}
});
});
</script>
<script src="/stylesheets/bootstrap/js/bootstrap.min.js"></script>
<!-- CSS -->
<link href="/stylesheets/bootstrap/css/bootstrap.min.css" rel="stylesheet" media="screen">
<link href="/stylesheets/bootstrap/css/bootstrap.css" rel="stylesheet" media="screen">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link href="/stylesheets/bootstrap/css/bootstrap-responsive.css" rel="stylesheet">
<link type="text/css" href="/stylesheets/bootstrapui/css/custom-theme/jquery-ui-1.10.0.custom.css" rel="stylesheet" />
</head>
<body>
<input type="text" id="search" class="search-query" placeholder="Search..." />
</head>
</body>
</html>
这是node.js代码:
app.post('/search', function (req, res){
var regex = new RegExp(req.body.term);
usermodel.aggregate({$match: { user: regex }}, function (err, users){
if (err) throw err;
var names = [];
for (var nam in users) {
names.push(users[nam].user);
}
var result = { results: names }
res.json(result);
});
});
此代码不起作用.我完全得到了AJAX请求,问题是Node.js响应.我不知道响应的类型或发送方式.names在包含所有结果的数组中,我发送它就像这样{ result: names }.也许我应该只发送res.json(result).在某些示例中使用GET请求,我使用POST,我应该更改吗？我使用mongodb和mongoose作为数据库.
我怎样才能做到这一点？谢谢你的进步!
对于自动填充表单,我建议twitter typeahead.非常简单,易于使用和强大.
