我无法循环访问JSON对象并在表格中显示某些值。基本上我想用每个新的数据实例创建一个新行。如果我创建的CodePen链接测试这个。有人能让我知道我错过了什么。谢谢！

jQuery.when (
jQuery.getJSON(campaigndata)

jQuery.each(data, function (i, item) {
var campaign_table = ''
stCallsHTML += '<tr><td>' + data[i].leadCall[0].campaign[0].name + '</td><td>' + data[i].leadCall[0].callType + '</td><td>' + data[i].leadCall[0].recordingUrl + '</td></tr>';
jQuery('#campaign_table').append(campaign_table);

我显然错过了与键/值配对的关系。所以，如果有人能让我直截了当，我会很感激。
答案 0 :(得分：1)
您在CodePen中使用了错误的选择器。基本上，你试图访问＆＃34;对象＆＃34;喜欢＆＃34;数组＆＃34;。必填字段的正确选择器为：
var campaignType = campaigndata.data[i].leadCall.campaign.name;
var leadType = campaigndata.data[i].leadCall.callType;
var recordingUrl = campaigndata.data[i].leadCall.recordingUrl;
以下是完整的解决方案：
var campaigndata = {

hasMore: true,

};
for (var i = 0; i < campaigndata.data.length; i++) {
var campaignType = "";
var leadType = "";
var recordingUrl = "";
if (campaigndata.data[i] != null)
if (campaigndata.data[i].leadCall != null) {
if (campaigndata.data[i].leadCall.campaign != null) {
campaignType = campaigndata.data[i].leadCall.campaign.name || "";
}
leadType = campaigndata.data[i].leadCall.callType || "";
recordingUrl = campaigndata.data[i].leadCall.recordingUrl || "";
}
var tableRowHTML =
"<tr><td>" +
campaignType +
"</td><td>" +
leadType +
"</td><td>" +
recordingUrl +
"</td></tr>";
jQuery("#campaign_table").append(tableRowHTML);
}<table class="tg" id="campaign_table" border='1'>
<tr>
<th class="tg-yw4l" colspan="1">Campaigns Type</th>
<th class="tg-yw4l" colspan="1">Lead Type</th>
<th class="tg-yw4l" colspan="1">Recording</th>
</tr>
</table>
如果你想使用jQuery，你应该这样做：
$.each(campaigndata.data, function(i) {
var campaignType = "";
var leadType = "";
var recordingUrl = "";
if (campaigndata.data[i] != null)
if (campaigndata.data[i].leadCall != null) {
if (campaigndata.data[i].leadCall.campaign != null) {
campaignType = campaigndata.data[i].leadCall.campaign.name || "";
}
leadType = campaigndata.data[i].leadCall.callType || "";
recordingUrl = campaigndata.data[i].leadCall.recordingUrl || "";
}
var tableRowHTML =
"<tr><td>" +
campaignType +
"</td><td>" +
leadType +
"</td><td>" +
recordingUrl +
"</td></tr>";
jQuery("#campaign_table").append(tableRowHTML);
});
我还为此here创建了一个jsfiddle。由于您已经在＆＃34; Campaigndata＆＃34;中提供了JSON数据。对象，您不需要使用jQuery.getJSON()或$.getJSON()。有关详细信息，请参阅this。
