我到目前为止所做的就是在每个表行上单击自定义按钮时使用window.alert显示行数据。但到目前为止,我还没有。 这是我的代码:
$.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;
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 ( json ) {
cacheLastJson = $.extend(true, {}, json);
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 );
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;
} );
} );
//
// DataTables initialisation
//
$(document).ready(function() {
$('#first_cycle').DataTable( {
"processing": true,
"serverSide": true,
"ajax": $.fn.dataTable.pipeline( {
url: 'scripts/server_processing.php',
pages: 5 // number of pages to cache
}),
"columnDefs": [ {
"targets": -1,
"data": null,
"defaultContent": "
<div class='w3-btn-group w3-vertical w3-row-padding'>
<a id='payment' >click1</a>
<button id='paymentDetails' >click2</button></div>"
}]
} );
$('#first_cycle tbody').on( 'click', '#paymentDetails', function () {
var data = table.row( $(this).parents('tr') ).data();
window.alert( data[1] );
} );
});
这把桌子拿得很好但是我似乎无法正确的部分是这部分
$('#first_cycle tbody').on( 'click', '#paymentDetails', function () {
var data = table.row( $(this).parents('tr') ).data();
window.alert( data[1] );
} );
我确保包含所有这些

https://cdn.datatables.net/1.10.13/js/jquery.dataTables.min.js
但是它仍然不起作用,如果有人能帮助我,我会很高兴。

根据您的评论判断,您似乎忘记将table
变量分配给Datatable的实例。
尝试将表声明为全局(var table
在脚本的开头,以便您可以随处访问它)并将DataTable的实例分配给它:
table = $("#first_cycle").DataTable({...});
