我试图在JavaScript中创建一个GIF API。每次我搜索另一个GIF时，它只是添加到我以前搜索的GIF中，除非我刷新它。我尝试在forEach代码块开始之前使用imagesEl.innerHTML = '';，但我意识到它不起作用。我还尝试在结束forEach代码块后使用if语句，但它不起作用，或者可能是因为我编码错误。任何评论都会有帮助！我很抱歉，如果我的一些句子是不正确的，我清楚地知道，我应该解释好他们的准确解决方案，这是因为英语不是我的第一语言。

const formEl = document.querySelector('form');
const loaderEl = document.querySelector('.loader');
const mainContainer = document.querySelector('.container')
const imgContainer = document.querySelector('.img-container')

function showLoader() {
    loaderEl.style.display = 'block';
}

function hideLoader() {
    loaderEl.style.display = 'none';
    loaderEl.innerHTML = '';
}

formEl.addEventListener('submit', (e) => {
    e.preventDefault();
    
    const input = formEl.querySelector('input[name="input"]').value;
    
    if (input.length >= 1){ 
        showLoader();
        performSearch(input);
    } else {
       hideLoader(input);   
    }
    e.target.reset();
    
});

function performSearch(search) {

    const gifCount = 10;
    const apiKey = 'VL071LzBWMdYPAyxErdI1d0YPs406vB5';
    const url = `https://api.giphy.com/v1/gifs/search?api_key=${apiKey}&q=${search}&limit=${gifCount}&offset=0&rating=pg-13&lang=en&bundle=messaging_non_clips`;

    fetch(url)
    .then((response) => response.json())
    .then((info) => {
        console.log(info.data)
        const giftData = info.data;
        
        giftData.forEach((e) => {
       
            // imagesEl.innerHTML = '';
            //create a div with classlist of images
            const imagesEl = document.createElement('div');
            imagesEl.classList.add('images');
            //inside images div create img to store the gifs.
            const img = document.createElement('img');
            img.setAttribute("src", e.images.fixed_height_downsampled.url);
            
            // append all
            imagesEl.appendChild(img);
            imgContainer.appendChild(imagesEl);
     
            //if(e > 10){
             imagesEl.innerHTML = '';}
            hideLoader();

            });
        });
    };
