Question

我有一个json对象数组，由$ .ajax（）检索并打印在表中。但是，我无法打印虽然他们通过XAMPP网页检索（在网络中看到＆gt;＆gt; xhr）。有人可以帮忙吗？

JSON：

{"people":[
    {"firstName":"Peter","lastName":"De'Souza","blogURL":"www.google.com"},
    {"firstName":"Romeo","lastName":"Cherolov","blogURL":"www.google.com"},
    {"firstName":"Caspian","lastName":"Monovola","blogURL":"www.google.com"}
    {"firstName":"Sita","lastName":"Martin","blogURL":"www.google.com"}
    {"firstName":"Rina","lastName":"Schenoi","blogURL":"www.google.com"}
]}

jQuery：

$.ajax({
      type: 'POST',
      url: 'http://localhost/example4/data.json',
      data: { patientID: "1" },
      contentType: 'application/json; charset=utf-8',
      dataType: 'json',
      success: function(jsonData) {

            for (i=0;i<5;i++)
            {
                console.log(jsonData[i].firstName);
            }

      },
      error: function() {
        alert('Some Error');
      }
});

它只是抛出错误警报，但在网络＆gt;＆gt; xhr我可以看到'人物 - json对象的数组'被提取。请帮助！

Answer 1

尝试console.log(jsonData.people[i].firstName);

Answer 2

将您的循环修改为

foreach(jsonData.people as val)
 {
       console.log(val['firstName']);
 }

$ .ajax（）打印一个没有打印的jsonObjects数组
