我使用OMDB的API使用电影数据到我的网站，但有些电影没有海报数据，所以它发送src="N/A".
<img src="<%=movie.Poster%>" alt="movie's poster" width="300px" height="450px">.
我在ejs中使用此代码来获取图像，但我希望在图像src="N/A"时更改图像src.
有人能帮帮忙吗？
以下是我的完整代码:
Index.js
import express from "express";
import bodyParser from "body-parser";
import pg from "pg"
import axios from "axios";
const app = express();
const port = 3000;
const API_URL = "https://www.omdbapi.com"
const apikey = "XXXXX"
let defaults = [
{
Title: "The Shawshank Redemption",
Year: "1994",
imdbID: "tt0111161",
Type: "movie",
Poster: "https://m.media-amazon.com/images/M/MV5BNDE3ODcxYzMtY2YzZC00NmNlLWJiNDMtZDViZWM2MzIxZDYwXkEyXkFqcGdeQXVyNjAwNDUxODI@._V1_SX300.jpg"
},
{
Title: "The Godfather",

}
];
let movies = defaults;
const db = new pg.Client({
user: "postgres",
host: "localhost",
database: "XXXXX",
password: "XXXX",
port: XXXX,
});
db.connect();
app.use(bodyParser.urlencoded({ extended: true }));
app.use(express.static("public"));
app.get("/",async(req,res)=>{
res.render("Index.ejs",{Movies:movies});
})
app.post("/",async(req,res)=>{
movies=[];
const title = req.body.title
const type = req.body.type
try{
const result = await axios.get(`${API_URL}/?apikey=${apikey}&s=${title}&type=${type}`);
const data = result.data;
//console.log(data.Search);
const response = data.Response; //response
if(response === "False"){ //for respone "False"
const error = data.Error; //error
res.render("Index.ejs",{Movies:movies,Error:error});
movies = defaults; //reset
}else{ // for respone "True"
const searchResult = data.Search;
const first10movie = searchResult; //show only first 10 movies of searching
//console.log(searchResult);
movies=first10movie;
//console.log(movies);
res.redirect("/");
}
}catch(err){
console.log(err);
}
})
app.listen(port, () => {
console.log(`Server running on port ${port}`);
});
