Datatables——回调函数

fnCookieCallback：还没有使用过
$(document).ready(function () {
$('#example').dataTable({
"fnCookieCallback": function (sName, oData, sExpires, sPath) {
// Customise oData or sName or whatever else here
return sName + "=" + JSON.stringify(oData) + "; expires=" + sExpires + "; path=" + sPath;
}
});
});

fnCreatedRow：顾名思义，创建行得时候的回调函数
$(document).ready(function () {
$('#example').dataTable({
"fnCreatedRow": function (nRow, aData, iDataIndex) {
// 为a的话字体加粗
if (aData[4] == "A") {
$('td:eq(4)', nRow).html('A');
}
}
});
});

fnDrawCallback：draw画 ，这个应该是重绘的回调函数
$(document).ready(function () {
$('#example').dataTable({
"fnDrawCallback": function (oSettings) {
alert('DataTables 重绘了');
}
});
});
fnFooterCallback：底部的回调函数，这个可以用来做总计之类的功能
$(document).ready(function() {
$('#example').dataTable({
"fnFooterCallback": function(nFoot, aData, iStart, iEnd, aiDisplay) {
nFoot.getElementsByTagName('th')[0].innerHTML = "Starting index is " + iStart;
}
});
});

fnFormatNumber：顾名思义，格式化数字的显示方式
$(document).ready(function () {
$('#example').dataTable({
"fnFormatNumber": function (iIn) {
if (iIn < 1000) {
return iIn;
} else {
var s = (iIn + ""),
a = s.split(""), out = "",
iLen = s.length;
for (var i = 0; i < iLen; i++) {
if (i % 3 === 0 && i !== 0) {
out = "'" + out;
}
out = a[iLen - i - 1] + out;
}
}
return out;
}
});
});

fnHeaderCallback：表头的回调函数
$(document).ready(function () {
$('#example').dataTable({
"fnHeaderCallback": function (nHead, aData, iStart, iEnd, aiDisplay) {
nHead.getElementsByTagName('th')[0].innerHTML = "Displaying " + (iEnd - iStart) + " records";
}
});
});

fnInfoCallback：datatables信息的回调函数
$('#example').dataTable({
"fnInfoCallback": function (oSettings, iStart, iEnd, iMax, iTotal, sPre) {
return iStart + " to " + iEnd;
}
});

fnInitComplete：datatables初始化完毕后会调用这个方法
$(document).ready(function () {
$('#example').dataTable({
"fnInitComplete": function (oSettings, json) {
alert('DataTables has finished its initialisation.');
}
});
});

fnPreDrawCallback：每一次绘datatables时候调用的方法
$(document).ready(function () {
$('#example').dataTable({
"fnPreDrawCallback": function (oSettings) {
if ($('#test').val() == 1) {
return false;
}
}
});
});

fnRowCallback：行的回调函数
$(document).ready(function () {
$('#example').dataTable({
"fnRowCallback": function (nRow, aData, iDisplayIndex, iDisplayIndexFull) {
// Bold the grade for all 'A' grade browsers
if (aData[4] == "A") {
$('td:eq(4)', nRow).html('A');
}
}
});
});

fnServerData：这个是结合服务器模式的回调函数，用来处理服务器返回过来的数据
// POST data to server
$(document).ready(function () {
$('#example').dataTable({
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "xhr.php",
"fnServerData": function (sSource, aoData, fnCallback, oSettings) {
oSettings.jqXHR = $.ajax({
"dataType": 'json',
"type": "POST",
"url": sSource,
"data": aoData,
"success": fnCallback
});
}
});
});

fnServerParams：向服务器传额外的参数
$(document).ready(function () {
$('#example').dataTable({
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "scripts/server_processing.php",
"fnServerParams": function (aoData) {
aoData.push({ "name": "more_data", "value": "my_value" });
}
});
});

fnStateLoad：读取状态的回调函数
$(document).ready(function () {
$('#example').dataTable({
"bStateSave": true,
"fnStateLoad": function (oSettings) {
var o;
// Send an Ajax request to the server to get the data. Note that
// this is a synchronous request.
$.ajax({
"url": "/state_load",
"async": false,
"dataType": "json",
"success": function (json) {
o = json;
}
});
return o;
}
});
});

fnStateLoadParams：和上面的不知道什么区别，没用过
// Remove a saved filter, so filtering is never loaded
$(document).ready(function () {
$('#example').dataTable({
"bStateSave": true,
"fnStateLoadParams": function (oSettings, oData) {
oData.oSearch.sSearch = "";
}
});
});

// Disallow state loading by returning false
$(document).ready(function () {
$('#example').dataTable({
"bStateSave": true,
"fnStateLoadParams": function (oSettings, oData) {
return false;
}
});
});

fnStateLoaded：又是这个，加了ed 不知道意思没用过
// Show an alert with the filtering value that was saved
$(document).ready(function () {
$('#example').dataTable({
"bStateSave": true,
"fnStateLoaded": function (oSettings, oData) {
alert('Saved filter was: ' + oData.oSearch.sSearch);
}
});
});

fnStateSave：状态储存
$(document).ready( function() {
$('#example').dataTable({
"bStateSave": true,
"fnStateSave": function(oSettings, oData) {
// Send an Ajax request to the server with the state object
$.ajax({
"url": "/state_save",
"data": oData,
"dataType": "json",
"method": "POST"
"success": function () {
}
});
};
});
});

fnStateSaveParams ：状态储存参数，没用过，不明白
// Remove a saved filter, so filtering is never saved
$(document).ready(function () {
$('#example').dataTable({
"bStateSave": true,
"fnStateSaveParams": function (oSettings, oData) {
oData.oSearch.sSearch = "";
}
});
});
