我想遍历 google books API 提供的项目数组并将结果打印在 div 中，但不知何故我无法这样做。这是我到目前为止所写的内容。
<body>
<div class="main-body">
<form id="form">
<div class="form-group">
<label for="usr">Enter Book Name</label>
<input type="search" class="form-control" id="search-text">
</div>
<div class="search-button">
<button onclick="function2();" type="button" id="search-button" class="btn btn-default">Search</button>
</div>
</form>
<div id="result">
<!--something seems wrong here-->
<h3 class="title"></h3>
<h4 class="author"></h4>
<img src="" alt="" class="thumbnail">
</div>
</div>
<script>
function function2(){
var result = document.getElementById('search-text').value;
$.ajax({
url: "https://www.googleapis.com/books/v1/volumes?q="+result,
type: 'GET',
dataType: 'json', // added data type
success: handleResponse
});
function handleResponse(res){
$.each(res.items,function(i,item){
var title = item.volumeInfo.title,
author = item.volumeInfo.authors[0],
thumb = item.volumeInfo.imageLinks.thumbnail;
<!--want to iterate over each element in items array and print it-->
$('.title').text(title);
$('.author').text(author);
$('.thumbnail').attr('src',thumb);
})
}
}
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</body>
最佳答案
您当前的代码会在每次迭代时用当前数据替换以前的数据。 做你想做的最简单的方法应该是构建新元素和append它们添加到您的“结果”div 中，如下所示。
我还建议验证数据。我用没有封面或作者的归还图书测试了一些查询。
function function2() {
var result = document.getElementById('search-text').value;
$.ajax({
url: "https://www.googleapis.com/books/v1/volumes?q=" + result,
type: 'GET',
dataType: 'json', // added data type
success: handleResponse
});
function handleResponse(res) {
$.each(res.items, function(i, item) {
var title = item.volumeInfo.title,
author = item.volumeInfo.authors[0],
thumb = item.volumeInfo.imageLinks.thumbnail;
var elTitle = $('<h3 class="title"></h3>').html(title),
elAuthor = $('<h4 class="author"></h4>').html(author),
elThumb = $('<img src="" alt="" class="thumbnail">').attr('src', thumb);
$('#result').append(elTitle, elAuthor, elThumb);
})
}
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<body>
<div class="main-body">
<form id="form">
<div class="form-group">
<label for="usr">Enter Book Name</label>
<input type="search" class="form-control" id="search-text">

<div class="search-button">
<button onclick="function2();" type="button" id="search-button" class="btn btn-default">Search</button>
</div>
</form>
<div id="result">
</div>
</div>
