我使用以下代码通过json_encode
提供数据库中的数据:
$orderList = $this->Retrieve->retrieve_data('*');
$data = array();
foreach ($orderList as $order) {
array_push($data, array(
'd' => $order['createdDate'],
'sales' => $order['order_price']
));
}
echo json_encode(array('data' => $data));
这是输出:
{"data":[{"d":"2015-09-26","sales":"0.00"},{"d":"2015-09-26","sales":"200.00"},{"d":"2015-09-26","sales":"45.00"},{"d":"2015-09-26","sales":"1500.00"}]}
这是我的Javascript代码:
$.ajax({
url: baseURL + '/Memberinfo/getGraphicalActivity',
cache: false,
type: "POST",
data: {patientFK: $("#patientFK").val()},
dataType: "json",
timeout:3000,
success : function (data) {
memberArea = new Morris.Line({
element: 'line-chart-memberInfo',
data: data,
xkey: 'd',
ykeys: ['sales'],
labels: ['Sales'],
smooth: false,
parseTime:false,
resize: true
});
},
error : function (xmlHttpRequest, textStatus, errorThrown) {
alert("Error " + errorThrown);
if(textStatus==='timeout')
alert("request timed out");
}
});
它返回此错误:
未捕获的TypeError:无法读取未定义的属性“x”
为什么会这样?

问题出在我如何用PHP构建我的JSON数据。这是代码:
java.lang.IndexOutOfBoundsException: Invalid index 18, size is 5
