我有一个 div 标签，并且动态添加一组 p 标签，它将从 json 获取值。问题是 p 标签被添加到同一个 div 中，而不是在单独的框中打印。下面是我的代码尝试实现逻辑。价格标签单独打印在同一 div 中，而其他标签未显示。
window.onload = function() {
document.getElementById('returnDate').style.display = 'none';
document.getElementsByClassName("flightDetails")[0].style.display = "none";
flightDetails = [{

最佳答案
尝试下一个代码，您缺少 <p> 之间的字符串连接运算符元素，并且您有一个比较器符号 <在这一切的中间应该是一个字符串。
for (i = 0; matches[0].detail.length; i++)
{
var div = document.createElement('div');
div.className = 'flightDetailBox';
div.innerHTML = '<p id="flightCost">' + 'Rs' + matches[0].detail[i].price + '</p>' +
'<p id="flightID">' + matches[0].detail[i].FlightNum + '</p>' +
'<p id="fromTo">' + matches[0].from + '>' + matches[0].to + '</p>' +
'<p id="departTime">' + matches[0].detail[i].departTime + '</p>' +
'<p id="ariveTime">' + matches[0].detail[i].arriveTime + '</p>' +
'<button type="submit" id="bookTicketButton" onclick="bookTicket()">BOOK TICKET</button>';
document.getElementById('flightDetails').appendChild(div);
}
另一种选择是使用 template literals :
for (i = 0; matches[0].detail.length; i++)
{
var div = document.createElement('div');
div.className = 'flightDetailBox';
div.innerHTML = `<p id="flightCost">Rs ${matches[0].detail[i].price}</p>` +
`<p id="flightID">${matches[0].detail[i].FlightNum}</p>` +
`<p id="fromTo">${matches[0].from} > ${matches[0].to}</p>` +
`<p id="departTime">${matches[0].detail[i].departTime}</p>` +
`<p id="ariveTime">${matches[0].detail[i].arriveTime}</p>` +
`<button type="submit" id="bookTicketButton" onclick="bookTicket()">BOOK TICKET</button>`;
document.getElementById('flightDetails').appendChild(div);
}
