Hello,
Im using datatables with server side loading via pipelining but I want searching + sorting to work. This does nothing unfortunately.
I get correct json back from the server which is loaded when I open the page with the table but when I want to use the sorting or searching functions it loads for a little second but does not update the table.
var table = $('#table_id').DataTable({
serverSide: true,
"processing": true,
"language": {
processing: '<svg class="circular" viewBox="25 25 50 50"><circle class="path" cx="50" cy="50" r="20" fill="none" stroke-width="2" stroke-miterlimit="10" /></svg>'
},
stateSave: true,
responsive: true,
dom: 'Bfrtip',
lengthMenu: [
[ 5, 10, 15 ],
[ '10 rows', '25 rows', '50 rows' ]
],
buttons: [
{
extend: 'pageLength'
},
{
text: 'Selecteer velden', extend: 'colvis'
}
],
ajax: $.fn.dataTable.pipeline( {
url: "{{route('pagination1')}}",
dataSrc : "data"
}),
"columns": [
{ "data": "ItemCode"},
{ "data": "Created" },
{ "data": "Description"},
{ "data": "PlannedQuantity"},
{ "data": "PlannedDate"},
{ "data": "Materiaal"},
]
});
The pipeline code:
$.fn.dataTable.pipeline = function (opts) {
// Configuration options
var conf = $.extend({
pages: 5, // number of pages to cache
url: '', // script url
data: null, // function or object with parameters to send to the server matching how `ajax.data` works in DataTables
method: 'GET' // Ajax HTTP method
}, opts);
// Private variables for storing the cache
var cacheLower = -1;
var cacheUpper = null;
var cacheLastRequest = null;
var cacheLastJson = null;
return function (request, drawCallback, settings) {
var ajax = false;
var requestStart = request.start;
var drawStart = request.start;
var requestLength = request.length;
var requestEnd = requestStart + requestLength;
// console.log(request);
// if (request.search['value'] == "") {
// if (request.order[0]) {
// var table = $('#table_id').DataTable();
// table
// .order( [[ 1, 'asc' ]] )
// .draw( );
// console.log(request.order[0]['column']);
// console.log(request.order[0]['dir']);
// }
// }
if (settings.clearCache) {
// API requested that the cache be cleared
ajax = true;
settings.clearCache = false;
} else if (cacheLower < 0 || requestStart < cacheLower || requestEnd > cacheUpper) {
// outside cached data - need to make a request
ajax = true;
} else if (JSON.stringify(request.order) !== JSON.stringify(cacheLastRequest.order) || JSON.stringify(request.columns) !== JSON.stringify(cacheLastRequest.columns) || JSON.stringify(request.search) !== JSON.stringify(cacheLastRequest.search)) {
// properties changed (ordering, columns, searching)
ajax = true;
}
// Store the request for checking next time around
cacheLastRequest = $.extend(true, {}, request);
if (ajax) {
// Need data from the server
if (requestStart < cacheLower) {
requestStart = requestStart - requestLength * (conf.pages - 1);
if (requestStart < 0) {
requestStart = 0;
}
}
cacheLower = requestStart;
cacheUpper = requestStart + requestLength * conf.pages;
request.start = requestStart;
request.length = requestLength * conf.pages;
// Provide the same `data` options as DataTables.
if ($.isFunction(conf.data)) {
// As a function it is executed with the data object as an arg
// for manipulation. If an object is returned, it is used as the
// data object to submit
var d = conf.data(request);
if (d) {
$.extend(request, d);
}
} else if ($.isPlainObject(conf.data)) {
// As an object, the data given extends the default
$.extend(request, conf.data);
}
settings.jqXHR = $.ajax({
"type": conf.method,
"url": conf.url,
"data": request,
"dataType": "json",
"cache": false,
"success": function success(json) {
cacheLastJson = $.extend(true, {}, json);
var data = json['data'];
for (var i = 0, leng = data.length; i < leng; i++) {
var material = data[i].ShopOrderMaterialPlans['results'];
for (var x = 0, len = material.length; x < len; x++) {
// console.log(material.length + " " + x);
if (getMaterial(material[x]['ItemCode'], 'TAP')) {
data[i]['Materiaal'] = material[x]['ItemCode'];
}
}
}
if (cacheLower != drawStart) {
json.data.splice(0, drawStart - cacheLower);
}
if (requestLength >= -1) {
json.data.splice(requestLength, json.data.length);
}
drawCallback(json);
}
});
} else {
json = $.extend(true, {}, cacheLastJson);
var data = json['data'];
for (var i = 0, leng = data.length; i < leng; i++) {
var material = data[i].ShopOrderMaterialPlans['results'];
for (var x = 0, len = material.length; x < len; x++) {
// console.log(material.length + " " + x);
if (getMaterial(material[x]['ItemCode'], 'TAP')) {
data[i]['Materiaal'] = material[x]['ItemCode'];
}
}
}
json.draw = request.draw; // Update the echo for each response
json.data.splice(0, requestStart - cacheLower);
json.data.splice(requestLength, json.data.length);
drawCallback(json);
}
};
};
// Register an API method that will empty the pipelined data, forcing an Ajax
// fetch on the next draw (i.e. `table.clearPipeline().draw()`)
$.fn.dataTable.Api.register('clearPipeline()', function () {
return this.iterator('table', function (settings) {
settings.clearCache = true;
});
});
function getMaterial(data, search) {
if (data && search) {
if (data.substr(0, 3) === search) {
return true;
} else {
return false;
}
}
}

So the search and sort is to be handled by your server-side processing script. Does it accept the data that DataTables sends?
