使用JavaScript和HTML显示API结果
[英]Display API results with JavaScript and HTML
问题描述
First off, I'm very new to working with APIs at all. 
首先，我很擅长使用API。 And English is not my first language. 英语不是我的第一语言。 I've searched the web but came up short in finding exactly what I'm looking for, or at least I have not understood enough of what I read to understand how to alter and apply it to my situation. 我已经在网上搜索过了，但却找不到我正在寻找的内容，或者至少我对自己所阅读的知识不够了解，以了解如何改变并应用于我的情况。
I'm working with the Omdb API and the Giphy API, making a silly page. 我正在使用Omdb API和Giphy API，制作一个愚蠢的页面。 I'm using JavaScript and HTML. 我正在使用JavaScript和HTML。
At the end I want the page to display the search result of the user searching for a movie + on-topic gifs. 最后，我希望页面显示用户搜索电影+主题上的GIF的搜索结果。
I've come so far that I have a result from both APIs. 到目前为止，我已经得到了两个API的结果。 That's all good and well. 这一切都很好，很好。 What I don't know how to do is to from these results present, for example, just the movie titles and the .gif-files. 我不知道怎么做的是从这些结果出现，例如，电影标题和.gif文件。 My attempts at splitting the returned results have so far failed. 我分裂返回结果的尝试到目前为止都失败了。 Any suggestions? 有什么建议么？ Below is my JavaScript code. 以下是我的JavaScript代码。
var form = document.getElementById('search-form');
form.addEventListener("submit", search);
function search(event) {
event.preventDefault();
document.getElementById("present_result").innerHTML = "";
if(this.elements.query.value === '') {
alert("Enter search word!");
} else {
var rawInputData = this.elements.query.value;
var fixedInputData = rawInputData.split(" ");
var inputData = encodeQueryData(fixedInputData);
var inputDataGif = encodeQueryDataGif(fixedInputData);
function encodeQueryData(data) {
let ret = [];
for (let d in data)
ret.push(encodeURIComponent(data[d]));
return ret.join('%20');
}
function encodeQueryDataGif(data) {
let ret = [];
for (let d in data)
ret.push(encodeURIComponent(data[d]));
return ret.join('+');
}
var omdbAPI = new XMLHttpRequest();
var gifAPI = new XMLHttpRequest();
var omdbURL = "http://www.omdbapi.com/?s=" + inputData + "&type=movie";
var gifURL = "http://api.giphy.com/v1/gifs/search?q=" + inputDataGif + "&limit=1&api_key=dc6zaTOxFJmzC";
omdbAPI.addEventListener("load", function() {
if (this.responseText === '{"Response":"False","Error":"Movie not found!"}')
{
alert("No result.");
} else {
var result = JSON.parse(this.responseText);
console.log(result);
result = JSON.stringify(result);
document.getElementById("present_result").innerHTML = result;
}
});
gifAPI.addEventListener("load", function() {
if (this.responseText === '{"Response":"False","Error":"Not found!"}')
{
alert("No Result.");
} else {
var result = JSON.parse(this.responseText);
console.log(result);
result = JSON.stringify(result);
document.getElementById("present_gif").innerHTML = result;
}
});
omdbAPI.open("get", omdbURL, true);
omdbAPI.send();
gifAPI.open("get", gifURL, true);
gifAPI.send();
}
}
And below the HTML. 在HTML下面。
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Mashup test</title>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<!-- Form -->
<form action="" method="get" id="search-form" class="search-form">
Movie: <input type="text" name="query">
<button type="submit" id="submit">Search</button>
</form>
<!-- Result -->
<div id="present_result">
</div>
<div id="present_gif">
</div>
<script src="scripts.js"></script>
</body>
</html>
And here's a sample result from OMDb: 以下是OMDb的示例结果：

Both APIs return you a JSON object. 两个API都返回一个JSON对象。
A json object is generally construct like so: 一个json对象通常是这样构造的：
{
"property1": "value1",
"property2": "value2"
"property_array": ["arrayValue1", "arrayValue2"],
"property_object": {
"propertyA": "valueA",
"attributeB": "valueB"
}
}
So let use OMDb (for example): 所以让我们使用OMDb（例如）：
to access the results, you need to acces the "Search" attribute : 要访问结果，您需要访问“搜索”属性：
var entries = result.Search;
Then, you need to "loop" on each property of the Search object (whitch is also an object) : 然后，您需要在Search对象的每个属性上“循环”（whitch也是一个对象）：
to do so, you can use a for...in loop: 为此，您可以使用for ... in循环：
for(var entry_key in entries) {
// control that property is own by the object (not prototype)
if(entries.hasOwnProperty(entry_key)) {
// do whatever you want with the entry
// To access the entry, use this notation:
var entry = entries[entry_key];
// to stay with OMDb example, this should be:
var movie_title = entry.Title;
}
}
var results = { "Search": [{ "Title": "Titanic", "Year": "1997", "imdbID": "tt0120338", "Type": "movie", "Poster": "https://images-na.ssl-images-amazon.com/images/M/MV5BZDNiMjE0NDgtZWRhNC00YTlhLTk2ZjItZTQzNTU2NjAzNWNkXkEyXkFqcGdeQXVyNjUwNzk3NDc@._V1_SX300.jpg" }, { "Title": "Titanic II", "Year": "2010", "imdbID": "tt1640571", "Type": "movie", "Poster": "https://images-na.ssl-images-amazon.com/images/M/MV5BMTMxMjQ1MjA5Ml5BMl5BanBnXkFtZTcwNjIzNjg1Mw@@._V1_SX300.jpg" }, { "Title": "Titanic: The Legend Goes On...", "Year": "2000", "imdbID": "tt0330994", "Type": "movie", "Poster": "https://images-na.ssl-images-amazon.com/images/M/MV5BMTg5MjcxODAwMV5BMl5BanBnXkFtZTcwMTk4OTMwMg@@._V1_SX300.jpg" }, { "Title": "Titanic", "Year": "1953", "imdbID": "tt0046435", "Type": "movie", "Poster": "https://images-na.ssl-images-amazon.com/images/M/MV5BMTU3NTUyMTc3Nl5BMl5BanBnXkFtZTgwOTA2MDE3MTE@._V1_SX300.jpg" }, { "Title": "Raise the Titanic", "Year": "1980", "imdbID": "tt0081400", "Type": "movie", "Poster": "https://images-na.ssl-images-amazon.com/images/M/MV5BMTY5MTQwNzMxNV5BMl5BanBnXkFtZTcwMzkwOTMyMQ@@._V1_SX300.jpg" }, { "Title": "The Legend of the Titanic", "Year": "1999", "imdbID": "tt1623780", "Type": "movie", "Poster": "https://images-na.ssl-images-amazon.com/images/M/MV5BMjMxNDU5MTk1MV5BMl5BanBnXkFtZTgwMDk5NDUyMTE@._V1_SX300.jpg" }, { "Title": "The Chambermaid on the Titanic", "Year": "1997", "imdbID": "tt0129923", "Type": "movie", "Poster": "https://images-na.ssl-images-amazon.com/images/M/MV5BMWUzYjgyNDEtNTAyMi00M2JjLTlhMzMtMDJmOGM1ZmYzNzY4XkEyXkFqcGdeQXVyMTA0MjU0Ng@@._V1_SX300.jpg" }, { "Title": "In Search of the Titanic", "Year": "2004", "imdbID": "tt1719665", "Type": "movie", "Poster": "https://images-na.ssl-images-amazon.com/images/M/MV5BMTAzNjY0NDA2NzdeQTJeQWpwZ15BbWU4MDIwMzc1MzEx._V1_SX300.jpg" }, { "Title": "Titanic", "Year": "1943", "imdbID": "tt0036443", "Type": "movie", "Poster": "https://images-na.ssl-images-amazon.com/images/M/MV5BMTU2Njg4MDgxN15BMl5BanBnXkFtZTcwNzE4MjYyMQ@@._V1_SX300.jpg" }, { "Title": "SOS Titanic", "Year": "1979", "imdbID": "tt0079836", "Type": "movie", "Poster": "https://images-na.ssl-images-amazon.com/images/M/MV5BMTMwOTU5MDU0OV5BMl5BanBnXkFtZTcwMDc4OTYyMQ@@._V1_SX300.jpg" }], "totalResults": "170", "Response": "True" }; var movies_list = document.getElementById('movies-list'); var entries = results.Search; for(var entry_key in entries) { // control that property is own by the object (not prototype) if(entries.hasOwnProperty(entry_key)) { // do whatever you want with the entry // To access the entry, use this notation: var entry = entries[entry_key]; // to stay with OMDb example, this should be: var movie_line = '<p><strong>Title:</strong> ' + entry.Title + ' (year: ' + entry.Year + ')</p>'; movies_list.innerHTML += movie_line; } }
