我想在nodejs中创建一个搜索页面。在我的代码中,我从另一个页面获取输入并将结果呈现到单独的页面:
app.post("/searchProcess", async (req, res) => {
const keyWord = req.body.search;
const searchMovies = await Movies.find({
name: { $regex: new RegExp(keyWord) }
})
const countMoviesSearch = await Movies.find({
name: { $regex: new RegExp(keyWord) }
}).countDocuments();
console.log(countMoviesSearch);
// console.log(keyWord);
res.render("searchResults",{
searchMovies: searchMovies,
countMoviesSearch: countMoviesSearch
});
});
这是我的“ searchResults”页面代码
<h1>{{searchMovies.name}}</h1>
<h2>{{countMoviesSearch}}</h2>
我目前得到countMoviesSearch
,但在searchmovies.name
中却未定义,我的所有输入变量都相同。

find()
方法返回一个Cursor
对象。您需要调用toArray()
来获取文档数组。由于有了数组,因此可以访问.length
属性以获取匹配的电影,以避免再次运行同一查询
app.post("/searchProcess", async (req, res) => {
const keyWord = req.body.search;
const searchMovies = await Movies.find({
name: { $regex: new RegExp(keyWord) }
}).toArray()
const countMoviesSearch = searchMovies.length
console.log(countMoviesSearch);
// console.log(keyWord);
res.render("searchResults",{
searchMovies: searchMovies,
countMoviesSearch: countMoviesSearch
});
});
