Question

我试图将一个充满对象的数组附加到表的主体中。

var tourTable = [];
var event = {
    date: eventDate,
    hour: eventOra
}
bookTable.push(event);

for(var i = 0; i < bookTable.length; i++) {
    $('#tour-events tbody').append('');
}

// table
<table id="tour-events">
    <thead></thead>
    <tbody></tbody>
</table>

我第一次单击一个按钮时一切似乎都很好，但是第二次尝试它时会添加比应该更多的元素。我在控制台中检查了数组并且元素数量很好。你有什么建议和其他方法吗？

Answer 1

您在variable声明array名称时错误bookTable名称应该是tourTable而不是var bookTable = []; var event = { date: eventDate, hour: eventOra } bookTable.push(event); for(var i = 0; i < bookTable.length; i++) { $('#tour-events tbody').append(''); } // table <table id="tour-events"> <thead></thead> <tbody></tbody> </table>

在顶部添加以下行：

$('#tour-events tbody').empty();
var bookTable = [];

将行附加到表中
