Datatable : Serverside global search does not send value in "search[value][0]" - jquery-plugins

Question

I have Datatable with server-side (MVC.net) paging, sorting, column filter and global search as follows
Html code
<table id="Grid" class="dataTable table table-striped table-bordered " style="width: 100% !important">
<thead>
<tr>
<th>Name</th>
<th>Name2</th>
<th>name3</th>
<th>name4</th>
<th>name5</th>
<th></th>
<th></th>
<th></th>
<th></th>
<th>last name</th>
</tr>
</thead>
<tbody>
</tbody>
<tfoot>
<tr>
<th> <input class="form-control texts" type="text" placeholder="Filter Name" id="filter0" maxlength="180" /></th>
<th> <input class="form-control texts" type="text" placeholder="Filter Host" id="filter1" maxlength="180" /></th>
<th> <select class="form-control selects" id="filter2">
<option value="select">Select</option>
<option value="1">2</option>
<option value="2">2</option>
</select> </th>
<th>
<select class="form-control selects" id="filter3">
<option value="select">Select</option>
<option value="1">true</option>
<option value="2">false/option>
</select>
</th>
<th><select class="form-control selects" id="filter4">
<option value="select">Select</option>
<option value="True">True</option>
<option value="false">False</option>
</select>
</th>
<th>
<select class="form-control selects" id="filter5">
<option value="select">Select</option>
<option value="True">True</option>
<option value="false">False</option>
</select>
</th>
<th></th>
<th></th>
<th>
<div class='input-group date col-xs-9' id="datepicker2">
<input class="form-control datepicker texts" type="text" placeholder="Filter Key expiration date" id="filter8" maxlength="10" />
<span class="input-group-addon">
<span class="ebsi-icon-calendar"></span>
</span>
</div>
</th>
<th>
<div class="btn-group btn-group-xs pull-right">
<input id="btnColumnFilters" class="datatable-action btn btn-sm btn-primary btn-secondary" type="button" value="Filter"/>
<input id="btnClearColumnFilters" class="datatable-action btn-sm btn btn-grey btn-secondary" type="button" value="Clear"/>
</div>
</th>
</tr>
<tfoot>
</table>
javascript code :
var ConfigTable = $('#Grid')
.on('preXhr.dt', function(e, settings, data) {
$(".alert").hide(); // hide any alerts
})
.DataTable({
autoWidth: true,
lengthChange: false,
responsive: true,
searching: true,
ordering: true,
paging: true,
pageLength: 10,
serverSide: true,
order: [[0, "asc"]],
ajax: {
url: "/controller/action",
type: "POST",
datatype: "json",
error: function (xhr, error, thrown) {
},
data: function(d) {
return $.extend({},
d,
{
});
}
},
columns: [
{ "data": "Name", "name": "Name", "autoWidth": true, "searchable": true },
{ "data": "Name2", "title": "Name2", "name": "Name2", "autoWidth": true, "searchable": true }.....
]
});
Column filter on button click
//send column filter data on button click
$("#btnColumnFilters").click(function() {
filterColumns.map(function (key, value) {
ConfigTable = ConfigTable.column(key).search($("#filter" + key).val());
});
ConfigTable.draw();
});
//server side search only when user hits enter or previous input has been cleared
$('#Grid_filter input').unbind();
$('#Grid_filter input').bind('keyup', function(e) {
if (e.keyCode == 13 || $(this).val() == "") {
// clear all filter selection
resetColumnFilters();
//apply filters
ConfigTable.columns().search(this.value).draw();
}
});
server-side code
[HttpPost]
public JsonResult action(jQueryDataTableParamModel param)
{
//globla filter
var search = Request.Form.GetValues("search[value]")[0];
// column filter
var Name = Request.Form.GetValues("columns[0][search][value]")[0];
}
but I am not getting global search value in "Request.Form.GetValues("search[value]")[0]" on the server side. it always comes as an empty string. what might be the issue, please help.
I am using 1.10.2 version of datatable plugin.
Update 1:
Checked in network tab of firebug for ajax request, empty string is being sent for each request for search parameter, even if search value is there
search[value] : ""
Update 2:
If I remove code to send global filter value only when enter is hit, it sends the search value to server
Update 3:
alert on this.value gives a value but
ConfigTable.columns().search(this.value).draw(); does not send value to server

Answer 1

Found the solution. removed columns() while sending global filter
$('#Grid_filter input').bind('keyup', function(e) {
if (e.keyCode == 13 || $(this).val() == "") {
// clear all filter selection
resetColumnFilters();
//removed columns()
ConfigTable.search(this.value).draw();
}
});
