angularJs中關於datatable的實作程式碼分享

本篇文章主要介紹了angularJs中datatable實作程式碼，小編覺得挺不錯的，現在分享給大家，也給大家做個參考。一起跟著小編過來看看吧

複製程式碼 程式碼如下:

<table datatable dtOptions="dtOptionsExample2" class="table table-striped m-b-none"></table>

controller設定：

$scope.dtOptions = { 
"bProcessing": true, 
"bServerSide": true, 
iDisplayLength: 5, 
sAjaxSource: 'http://10.188.192.200:8080/employee/page?deptId='+ data, 
sAjaxDataProp: 'aaData', 
"sDom": "<&#39;row&#39;<&#39;col-sm-6&#39;l><&#39;col-sm-6&#39;f>r>t<&#39;row&#39;<&#39;col-sm-6&#39;i><&#39;col-sm-6&#39;p>>", 
sPaginationType: "full_numbers", 
"aoColumns": 
[ 
{ "mData": "employeeId" }, 
{ "mData": "employeeName", 
"sClass": "center", 
"mRender": function(data,type,full) { 
return &#39;<a class="emplyeeInfoLink" href="javascript:;" rel="external nofollow" >阿司法所</a>&#39;; 
} 
}, 
{ "mData": "employeeEmail" }, 
{ "mData": "employeeMobilePhoneMaster" } 
], 
/*"aoColumnDefs":[ 
{ 
"aTargets":[4], 
"mData": null 
} 
],*/ 
"fnServerData": function( sUrl, aoData, fnCallback, oSettings ) { 
oSettings.jqXHR = $.ajax({ 
"url": sUrl, 
beforeSend: function(xhr) { 
xhr.withCredentials = true; 
}, 
"data": aoData, 
"type": &#39;get&#39;, 
"success": fnCallback, 
"cache": false 
}); 
} 
}

angular.datatable.js:

angular.module('datatablesDirectives', []).directive('datatable', function ($http) { 
 return { 
 // I restricted it to A only. I initially wanted to do something like 
 // <datatable> <thead> ... </thead> </datatable> 
 // But thead elements are only valid inside table, and <datatable> is not a table. 
 // So.. no choice to use <table datatable> 
 restrict: &#39;A&#39;, 
 
 link: function ($scope, $elem, attrs) { 
  var options = {};

  if (attrs[&#39;dtoptions&#39;] === undefined) { 
 
   // Get the attributes, put it in an options 
   // We need to do a switch/case because attributes does not retain case 
   // and datatables options are case sensitive. Damn. It&#39;s okay! We need to detect 
   // the callbacks anyway and call it as functions, so it works out! 
   // I put what I needed, most of my settings are not dynamics except those 2. 
   for (property in attrs) {

  // Obviously, mdata is the only one required. 
  // I personally just needed those 3, if you need other more feel free to add it. 
  // mData also accepts a function; I&#39;m sure there&#39;s a more elegant way but for now 
  // it detects if it&#39;s a function, and if it is, do it. 
  options.aoColumns = [];
