[英]DataTables warning: table id=example - Invalid JSON response
I have googled for the answer of this question but noone helped. 我搜索了这个问题的答案,但没有人帮忙。 I am getting error mentioned in title. 我在标题中提到了错误。
Here is my ajax code : 这是我的ajax代码:
var table = $('#example').DataTable( {
"ajax": "<?php echo $root; ?>ajax/order.php",
"processing": true,
"serverSide": true,
"ordering": false,
"searching": true,
"columns": [
{ "data": "order_no" },
{ "data": "country" },
{ "data": "name" },
{ "data": "date","className": "align-center" },
{ "data": "subtotal","className": "align-right" },
{ "data": "dileveryAmt","className": "align-right" },
{ "data": "totalAmt","className": "align-right" },
{ "data": "paymentMode","className": "align-center" },
{ "data": "payment","className": "align-center" },
{ "data": null,"defaultContent": "<button id='view' class='btn btn-small btn-info'>View</button><button id='delete' class='btn btn-small btn-danger'>Delete</button>","className": "align-center" }
]
} )
I validated Response from server ( as seen in Developer tools) and its being shown as Valid JSON. 我验证了来自服务器的响应(如开发人员工具中所示),并显示为有效JSON。 But its not reflected in page. 但它没有反映在页面中。
My HTML Code is 我的HTML代码是
<table id="example" class="display table-bordered" cellspacing="0" width="100%">
<thead>
<tr>
<th>Order No</th>
<th>Country</th>
<th>Customer</th>
<th>Date</th>
<th>Sub Total</th>
<th>Delivery Charge</th>
<th>Total</th>
<th>Payment Mode</th>
<th>Payment</th>
<th>Action</th>
</tr>
</thead>
UPDATE UPDATE
Response from Server(there are plenty of entries. I am showing one as example): 来自服务器的响应(有很多条目。我以一个例子显示):
"data": [
{
"id": "183",
"customer_id": "183",

"dileveryAmt": "0.00",

},
Any help will be appreciated. 任何帮助将不胜感激。
I struggled with this. 我为此苦苦挣扎。 and after I RTM here https://www.datatables.net/examples/ajax/custom_data_flat.html I figured it out. 在我RTM之后https://www.datatables.net/examples/ajax/custom_data_flat.html我明白了。
ajax: {
url: "data/objects_root_array.txt", <-- notice url and the link
dataSrc: "" <-- if you are just going to json_encode the result from the db. it will handle a flat string
}
ajax calls are done a certain way. ajax调用是以某种方式完成的。 not just ajax. 不仅仅是ajax。 but you need to include the url and dataSrc variables in there. 但是你需要在那里包含url和dataSrc变量。 After I did that with my code everything worked as it should. 在我用我的代码完成后,一切正常。
See if this works for you. 看看这是否适合你。
var table = $('#example').DataTable( {
"ajax": {
url: "<?php echo $root; ?>ajax/order.php",
dataSrc : ""
},
"processing": true,
"serverSide": true,
"ordering": false,
"searching": true,
"columns": [
{ "data": "order_no" },
{ "data": "country" },
{ "data": "name" },
{ "data": "date","className": "align-center" },
{ "data": "subtotal","className": "align-right" },
{ "data": "dileveryAmt","className": "align-right" },
{ "data": "totalAmt","className": "align-right" },
{ "data": "paymentMode","className": "align-center" },
{ "data": "payment","className": "align-center" },
{ "data": null,"defaultContent": "<button id='view' class='btn btn-small btn-info'>View</button><button id='delete' class='btn btn-small btn-danger'>Delete</button>","className": "align-center" }
]
} )
Think the problem is paymentMode
. 认为问题是paymentMode
。 It is written without underscore in the table definition and with underscore in your json ( "payment_mode":
) 它在表定义中没有下划线,在json中使用下划线( "payment_mode":
The answer should look like this: 答案应如下所示:
{
"data": [
{
"id": "183",
"customer_id": "183",
"subtotal": "0.00",
"totalAmt": "0.00",
"dileveryAmt": "0.00",
"date": "18/02/2015",
"midnightdelivery": "0",
"delivery_date": "2015-02-19",
"message_on_cake": "",
"special_instruction": "",
"payment": "<div class='label label-warning'>Pending</div>",
"delivery": "0",
"created": "2015-02-18 10:58:29",
"ip": "",
"payment_mode": "",
"first_name": "Ganesh",
"last_name": "Salunkhe",
"email": "g@s.com",
"address": "",
"flat_no": "k",
"building_name": "k",
"street": "k",
"area": "k",
"landmark": "k",
"city": "mumbai",
"country": "India",
"state": "maharashtra",
"contact_no": "7666902899",
"name": "Ganesh Salunkhe",
"order_no": "1181"
}
]
}
