I am using server-side DataTables in a project 我在项目中使用服务器端DataTables
and do a search, shows me the following error message: 并进行搜索,显示以下错误消息:
DataTables warning: JSON data from server not could be parsed. This is Caused by a JSON formatting error.
I found some suggestions in the forums but nothing has worked for me 我在论坛上找到了一些建议,但没有任何对我有用
Anyone have any suggestions? 有人有什么建议吗?
检查firebug中的网络选项卡,您可能会看到底层服务器错误
I ran into this problem and it was as simple as updating the information in the following file: 我遇到了这个问题,就像更新以下文件中的信息一样简单:
"sAjaxSource": "DataTables/examples/server_side/scripts/server_processing.php"
Don't know if the answer you're looking for is that pedestrian, but I figured I would throw in my 2 cents!! 不知道你所寻找的答案是否是行人,但我想我会投入2美分!
你的json不是数据表所期望的有效格式,即行/列2d数组。
[["row1col1","row1col2"],["row2col1"],.....]
For newer versions of datatables,don't forget to remove this line from the server_processing.php file 对于较新版本的数据表,请不要忘记从server_processing.php文件中删除此行
/* REMOVE THIS LINE (it just includes my SQL connection user/pass) */
include( $_SERVER['DOCUMENT_ROOT']."/datatables/mysql.php" );
If you are using : 如果您正在使用:
"sAjaxSource": "myHandler.php"
Then you mus return from your handler: 然后你从你的处理程序返回:
"{\"aaData\": [{\"propOne\": \"valueOne\"},{\"propTwo\": \"valueTwo\"}], [...],... }"
Note 注意
\"aaData\":
before json collection and note brakects: 在json收集和注意brakects之前:
{\"aaData\"....}
My example in asp.net(this is working): 我在asp.net中的例子(这是有效的):
Response.Write("{\"aaData\": [{\"propOne\": \"valueOne\"},{\"propTwo\": \"valueTwo\"}]}");
Client page: 客户页面:
oTable = $('#myTable').dataTable( {
"bProcessing": true,
"sPaginationType": "full_numbers",
"aLengthMenu": [[5,10,20,50,100], [5,10,20,50,100]],
"aaSorting": [[ 1, "desc" ]],
"sAjaxSource": "MyHandler.ashx",
"aoColumns": [
{ "mDataProp": "propOne" },
{ "mDataProp": "propTwo" }
]
});
