我需要从JSON对象中检索 sprintID 和 issue_name 并将它们添加到表中。以下是我到目前为止所做的工作。
以下是一些示例JSON。

这是不起作用的循环。
$(mock_data.sprints).each(function(i, value) {
$(sprints.value).each(function(j, val) {
$('.list').append('<tr>' +
'<td>' + (i + 1) + '</td>' +
'<td>' + val.sprintID + '</td>' +
'<td>' + val.issue_name + '</td>' +
'</tr>');
});
});
HTML就是这样，<table class="list"></table>
答案 0 :(得分：6)
问题是内部循环试图访问未定义的变量rmarkdown。您需要做的就是更正脚本，在第二个循环中将maximumBillingTier更改为sprints.value，以迭代sprints.value数组中的对象。
value.issues
issues$(mock_data.sprints).each(function(i, value) {
$(value.issues).each(function(j, val) {
$('.list').append('<tr>' +
'<td>' + (i + 1) + '</td>' +
'<td>' + val.sprintID + '</td>' +
'<td>' + val.issue_name + '</td>' +
'</tr>');
});
});
