我有一个javascript和html代码：
<script type="text/javascript" src="jquery-1.11.3.js"> </script>
<script type="text/javascript">
$(document).ready(function()
{
$.ajax({
url: "getjson.php",
type: "POST",
success: function (response)
{
console.log(response);
var trHTML = '';
$.each(response, function (i, item)
{
trHTML +=
'<tr><td>' + item.id +
'</td><td>' + item.konu +
'</td><td>' + item.aciklama +
'</td><td>' + item.giris_tarih +
'</td><td>' + item.degistirilme_tarih +
'</td><td>' + item.ad_soyad +
'</td><td>' + item.email +
'</td></tr>';
});
$('#records_table').append(trHTML);
}
});
});
</script>
<table id="records_table" border='1'>
<tr>
<th align="center" width="50">Id</th>
<th align="center" width="100">Konu</th>
<th align="center" width="100">Aciklama</th>
<th align="center" width="100">Giris Tarih</th>
<th align="center" width="150">Degistirilme Tarih</th>
<th align="center" width="100">Ad Soyad</th>
<th align="center" width="100">Email</th>
</tr>
</table>
此代码不起作用。它只创建第一行，但不从getjson.php获得json响应。当我像这样在jsfiddle中将其与静态json数据一起使用时https://jsfiddle.net/tqyn3/761/，它按我的意愿工作。但是我想从getjson.php获取数据。如何将其转换为动态？
更新：在调试器控制台中，它在上面写道：
showjson.php:12
{"kullanicilar":[{"id":"6","konu":"blood angels","aciklama":"primarch","giris_tarih":"0000-00-00","degistirilme_tarih":"0000-00-00","ad_soyad":"singuinius","email":"warhammer"},{"id":"7","konu":"emperors children","aciklama":"daemon primarch","giris_tarih":"0000-00-00","degistirilme_tarih":"0000-00-00","ad_soyad":"fulgrim","email":"warhammer"},{"id":"8","konu":"night lords","aciklama":"primarch","giris_tarih":"0000-00-00","degistirilme_tarih":"0000-00-00","ad_soyad":"konrad curze","email":"warhammer"},{"id":"9","konu":"grey knights","aciklama":"grand master","giris_tarih":"0000-00-00","degistirilme_tarih":"0000-00-00","ad_soyad":"grand master","email":"warhammer40k"},{"id":"10","konu":"dark angels","aciklama":"primarch","giris_tarih":"0000-00-00","degistirilme_tarih":"0000-00-00","ad_soyad":"lion el jonson","email":"warhammer40k"}]}
它在下面用红色文本写道：
jquery-1.11.3.js:577 Uncaught TypeError: Cannot use 'in' operator to search for 'length' in
{"kullanicilar":[{"id":"6","konu":"blood angels","aciklama":"primarch","giris_tarih":"0000-00-00","degistirilme_tarih":"0000-00-00","ad_soyad":"singuinius","email":"warhammer"},{"id":"7","konu":"emperors children","aciklama":"daemon primarch","giris_tarih":"0000-00-00","degistirilme_tarih":"0000-00-00","ad_soyad":"fulgrim","email":"warhammer"},{"id":"8","konu":"night lords","aciklama":"primarch","giris_tarih":"0000-00-00","degistirilme_tarih":"0000-00-00","ad_soyad":"konrad curze","email":"warhammer"},{"id":"9","konu":"grey knights","aciklama":"grand master","giris_tarih":"0000-00-00","degistirilme_tarih":"0000-00-00","ad_soyad":"grand master","email":"warhammer40k"},{"id":"10","konu":"dark angels","aciklama":"primarch","giris_tarih":"0000-00-00","degistirilme_tarih":"0000-00-00","ad_soyad":"lion el jonson","email":"warhammer40k"}]}
我终于自己找到了答案：固定代码为：
$(document).ready(function()
{
$.ajax({
url: "getjson.php",
type: "POST",
dataType:"json",
success: function (response)
{
var trHTML = '';
$.each(response, function (key,value) {
trHTML +=
'<tr><td>' + value.id +
'</td><td>' + value.konu +
'</td><td>' + value.aciklama +
'</td><td>' + value.giris_tarih +
'</td><td>' + value.degistirilme_tarih +
'</td><td>' + value.ad_soyad +
'</td><td>' + value.email +
'</td></tr>';
});
$('#records_table').append(trHTML);
}
});
});
我应该添加"dataType:"json"，"html是：
<table id="records_table" border='1'>
<tr>
<th align="center" width="50">Id</th>
<th align="center" width="100">Konu</th>
<th align="center" width="100">Aciklama</th>
<th align="center" width="100">Giris Tarih</th>
<th align="center" width="150">Degistirilme Tarih</th>
<th align="center" width="100">Ad Soyad</th>
<th align="center" width="100">Email</th>
</tr>
</table>
确保在PHP中将头设置为JSON。验证响应变量是否也具有您期望的结构。这可能是php中结构创建的问题。有时json_encode会做一些与您预期不同的事情。
控制台日志代表把它放在这里：
success: function(response) {
console.log(response);
// the rest of your code
}
尝试：
success: function (response)
{
console.log(response);
var trHTML = '';
var data = response.kullanicilar;
for(var i = 0; i < data.length; i++)
{
trHTML +=
'<tr><td>' + data[i].id +
'</td><td>' + data[i].konu +
'</td><td>' + data[i].aciklama +
'</td><td>' + data[i].giris_tarih +
'</td><td>' + data[i].degistirilme_tarih +
'</td><td>' + data[i].ad_soyad +
'</td><td>' + data[i].email +
'</td></tr>';
};
$('#records_table').append(trHTML);
}
