我正在寻找一种方法来附加一些JSON结果,我正在使用一个列表(数组?)并且有多个元素,我知道我可以直接在JS代码中添加一些样式但是我更舒服用这种方法。如何迭代元素并在某些div中实现,然后使用下一个元素创建类似的div。
实现这一目标的唯一方法是:
$("#article").append(data[i].datetime + data[i].headline + "<br />" + "<hr />" + data[i].summary);
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Project JS 02</title>
<link rel="stylesheet" href="assets/main.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
</head>
<body>
<div class="container container-table">
<div class="row vertical-center-row">
<div class="col-md-4 col-md-offset-4">
<button type="submit" class="btn btn-primary" style="width: 100%" class="search" id="getnews">Get News!</button>
<h1 id="headline"></h1><br>
<h3 id="datetime"></h3><br>
<div id="summary"></div><br>
<h6 id="source"></h6><br>
</div>
</div>
</div>
<script src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
<script>
document.getElementById("getnews").addEventListener("click", function () {
var newsurl = "https://api.iextrading.com/1.0/stock/aapl/news"
$.getJSON(newsurl, function (data) {
for (i in data)
{
$("#headline").append(data[i].headline);
$("#datetime").append(data[i].datetime);
$("#summary").append(data[i].summary);
$("#source").append(data[i].source);
}
})
})
</script>
</body>
</html>

您可以根据需要创建元素(使用jQuery)并将它们附加到容器中来执行此操作:
$("#getnews").on("click", function () {
var newsurl = "https://api.iextrading.com/1.0/stock/aapl/news"
$('#data').text("...loading...");
$.getJSON(newsurl, function (data) {
$('#data').html("");
data.forEach(function (article) {
$('#data').append(
$('<h1>').text(article.headline),
$('<h3>').text(article.datetime),
$('<div>').text(article.summary),
$('<h6>').text(article.source)
);
});
});
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="btn btn-primary search"
style="width: 100%" id="getnews">Get News!</button>
<div id="data"></div>

首先:删除ID。如果你想创建类似的容器,那么id会多次出现,这将无法工作。
第二:用$('.row.vertical-center-row')
取div并克隆它。
第三步:在克隆的HTMLNode上设置值,并将其附加到$('.container.container-table')
类似的东西(未经测试的):
<div class="container container-table">
<div class="row vertical-center-row">
<div class="col-md-4 col-md-offset-4">
<button type="submit" class="btn btn-primary" style="width: 100%" class="search" class="getnews">Get News!</button>
<h1 class="headline"></h1><br>
<h3 class="datetime"></h3><br>
<div class="summary"></div><br>
<h6 class="source"></h6><br>
</div>
</div>
</div>
<script>
document.getElementsByClassName("getnews").forEach((el)=>el.addEventListener("click", function () {
var newsurl = "https://api.iextrading.com/1.0/stock/aapl/news"
$.getJSON(newsurl, function (data) {
var $elClone = $('.row.vertical-center-row').clone(true).appendTo($('.container.container-table'));
for (i in data) {
$(".headline", $elClone).append(data[i].headline);
$(".datetime", $elClone).append(data[i].datetime);
$(".summary", $elClone).append(data[i].summary);
$(".source", $elClone).append(data[i].source);
}
})
}));
</script>
