jquery - Sending JSON Objects in DataTables from javascript -


i trying populate datatable json object getting following error:

datatables warning: table id=filteredalertstable - requested unknown parameter 'messageid' row 0. more information error, please see http://datatables.net/tn/4

here code:

var dataset = '${data}'; $('#filteredalertstable').datatable( {         "bprocessing": true,         "aadata": dataset,         "aocolumns": [                       { "mdata": "messageid" },                       { "mdata": "host" },                       { "mdata": "creationtime" },                       { "mdata": "resolvedtime" },                       { "mdata": "severity" },                       { "mdata": "alerttext" }         ]     } );

i getting dataset javascript variable, tried passing following,

[{     "severity": "severity",     "creationtime": "creationtime",     "resolvedtime": "resolvedtime",     "appname": "appname",     "host": "host",     "messageid": "messageid",     "alerttext": "alerttext" }, {     "severity": "severity1",     "creationtime": "creationtime1",     "resolvedtime": "resolvedtime1",     "appname": "appname1",     "host": "host1",     "messageid": "messageid1",     "alerttext": "alerttext1" }]

and

{     "mdata": [{         "severity": "severity",         "creationtime": "creationtime",         "resolvedtime": "resolvedtime",         "appname": "appname",         "host": "host",         "messageid": "messageid",         "alerttext": "alerttext"     },     {         "severity": "severity1",         "creationtime": "creationtime1",         "resolvedtime": "resolvedtime1",         "appname": "appname1",         "host": "host1",         "messageid": "messageid1",         "alerttext": "alerttext1"     }] }

i have gone thought this question still can't figure out what's wrong

here html code.

<table id="filteredalertstable"     class="table table-striped table-bordered ">     <thead>         <tr>             <th>message id</th>             <th>host</th>             <th>creation time</th>             <th>resolved time</th>             <th>severity</th>             <th>alert text</th>         </tr>     </thead>     <tbody>     </tbody> </table>

it because dataset string. caused '${data}' datatable looks :

var dataset = '[{ "severity": "severity", "creationtime": "creationtime", "resolvedtime": "resolvedtime", "appname": "appname", "host": "host", "messageid": "messageid",    "alerttext": "alerttext"},{    "severity": "severity1",    "creationtime": "creationtime1", "resolvedtime": "resolvedtime1", "appname": "appname1", "host": "host1", "messageid": "messageid1", "alerttext": "alerttext1"}]';

as json works right away -> http://jsfiddle.net/q78tu48q/

so make sure string is in json format :

$('#filteredalertstable').datatable( {         "bprocessing": true,         "aadata": json.parse(dataset),         "aocolumns": [                       { "mdata": "messageid" },                       { "mdata": "host" },                       { "mdata": "creationtime" },                       { "mdata": "resolvedtime" },                       { "mdata": "severity" },                       { "mdata": "alerttext" }         ]     } );

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
