Question

我的问题：看起来我的代码在某处不正确。搜索不起作用。我是使用API的新手。

如何获取用户搜索的特定搜索结果？

Giphy API的GitHub链接位于：https://github.com/Giphy/GiphyAPI。

JS

document.addEventListener('DOMContentLoaded', function () {

//q = "";

request = new XMLHttpRequest;
//request.open('GET', 'http://api.giphy.com/v1/gifs/random?api_key=dc6zaTOxFJmzC&tag='+q, true);
request.open('GET', 'http://api.giphy.com/v1/gifs/search?q=funny+cat&api_key=dc6zaTOxFJmzC');


request.onload = function() {
    if (request.status >= 200 && request.status < 400){
        data = JSON.parse(request.responseText).data.image_url;
        console.log(data);
        document.getElementById("here_is_gif").innerHTML = '<center><img src = "'+data+'"  title="GIF via Giphy"></center>';
    } else {
        console.log('reached giphy, but API returned an error');
     }
};

request.onerror = function() {
    console.log('connection error');
};

request.send();
});

HTML

<h1> Let's Search Some Gifs! </h1>
<div class="info">
    <p> Search below to the wonderful world of Gifs! </p>
        <form class="gif-form">
            <input type="text" id="form-value" class="search-input-rounded">
            <button type="submit" class="search_button"> Search for GIFs </button>
            <input type="reset" value="Reset">
        </form>
        <div class="rando_facts animated bounceIn">
            <p id="here_is_gif"> </p>
        </div>
</div>

Answer 1

这是jQuery的解决方案。欲了解更多信息，请参阅他们的文档...... http://api.jquery.com/

另请注意，Giphy API会回复图像的URL，而不是图像本身。因此，<img>标记替换了您最初使用的<p>。使用src属性使用网址呈现图片。

检查浏览器的控制台日志，了解API响应的外观。

下面是完整的HTML，请注意jQuery必须始终链接在代码上方。

    $( document ).ready(function(){

      $('.search_button').on('click', function(){

        // Collect user by grabbing the input form's value via id (#)
        var userInput = $('#form-value').val().trim();
        
        // Change the input to suit the API (ie change spaces to +)
        userInput = userInput.replace(/ /g, "+");

        // Create the Giphy API URL
        var queryURL = 'http://api.giphy.com/v1/gifs/search?q=' + userInput + '&api_key=dc6zaTOxFJmzC';

        // Part 2 - Use AJAX to call GIPHY API (note that the .done() function waits for the API to respond)
        $.ajax({url: queryURL, method: 'GET'}).done(function(response){

          // This is the API response data. It's a JSON object of 25 gifs
          console.log(response.data);

          // For simplicity, we will take the first gif (ie. at postion 0)
          var giphyURL = response.data[0].images.fixed_height.url;

        // Part 3 - Clear the Gif using the reset_button id (#)

Answer 2

提取用户输入后，您可以输入变量...

您的API链接（此处复制）只是搜索＆＃34;有趣的猫＆＃34;。 request.open('GET', 'http://api.giphy.com/v1/gifs/search?q=funny+cat&api_key=dc6zaTOxFJmzC');

你可以通过做这样的事情来解决这个问题......

var searchTerm = prompt('Add your search term here'); searchTerm = searchTerm.trim().replace(/ /g, "+"); // adds a + wherever a space is request.open('GET', 'http://api.giphy.com/v1/gifs/search?q=' + searchTerm + '&api_key=dc6zaTOxFJmzC');

因为，我不确定您是否粘贴了所有正在使用的代码，我只演示了如何将funny+cat之类的短语替换为名为searchTerm的变量。

为了从<input>字段中提取用户的输入，您可以使用jQuery，然后将其传递到搜索字词变量中。

奇怪的是，我已经使用Giphy API完成了project。
