在我的Laravel应用程序中,我有多个页面,我有DataTables。他们都有“mydttable”类。我使用Ajax将数据加载到DataTables中。
在每个表的每一行,我有一个带删除按钮的列。每当我按下时,我在相应的行then I want to reload the data into the datatable
上执行删除。我可以通过使用if语句询问哪个tabel上有按钮来做到这一点,但我想知道是否有更简单的方法来执行此重新加载。
更确切地说......
是我的custom.js,我做的数据填充方式如下:
var uzTable = $('#users').DataTable( {
"processing": true,
"serverSide": true,
"sAjaxSource": "sspXController?draw=1",
...
});
var cliTable = $('#clients').DataTable( {
"processing": true,
"serverSide": true,
"sAjaxSource": "sspXController2?draw=1",
...
});
var marTable = $('#market').DataTable( {
"processing": true,
"serverSide": true,
"sAjaxSource": "sspXController3?draw=1",
...
});
现在,在删除点击事件,我在哪里进行删除,并希望进行重新加载
$( document ).on('click', '.ssDelete', function(e){
e.preventDefault();
$.ajax({
url: someFormAction,
type: 'POST',
dataType: 'html',
success:function(data) {
$(".mydttable").ajax.reload();
}
});
我的HTML就像:
<table id="users" class="row-border hover order-column table mydttable dataTable no-footer" cellspacing="0" width="100%">
<thead>
<tr role="row">
<th class="small-sorting" style="width:84px"></th>
<th class="small-sorting" style="width:84px">Operatiuni</th>
</tr>
</thead>
<tbody>
<tr>
<td></td>
<td></td>
</tr>
</tbody>
</table>
当然,上面的HTML只是第一个DataTable(“用户”)的HTML,其他表也有HTML代码,但我不会在这里粘贴它以避免使这个问题过长。 此外,在任何给定时间,视图(html)中都会显示仅一个dataTable
因此,当我点击带有ssDelete ID的任何按钮时,我会删除当前显示的dataTable的当前记录,并且我想刷新包含删除按钮的dataTable。由于我没有单独为每个表执行删除功能,我希望能够为ajax重新加载更短的时间。
因此,我的目标是能够在单击“#ssDelete”按钮时重新加载文档中加载的任何DataTable,而无需额外的重新标记和条件... 我的尝试无效:
success:function(data) {
$(".mydttable").ajax.reload(); // NOT WORKING
...
我该怎么做? 的修改 人们似乎没有阅读我的整个问题,所以我将在此重复它的本质: 我需要能够只有一个功能来删除多个dataTables的记录。为了做到这一点(删除部分已经完成和工作)我需要能够刷新/重新加载VISIBLE dataTable的内容。我需要这样做,而不必测试哪些表是可见的。 基于我的所有dataTable共享同一个类的事实,我应该能够调用一个通用的dataTable并向它应用ajax.reload()函数。但它不起作用。我需要一种方法来访问当前VIEW中的任何dataTable,使用一些通用的方式......类似于:
$(".mydttable").ajax.reload();
或
$('.mydttable').dataTable().fnReloadAjax();
或
$('.mydttable').DataTable().ajax.reload();
显然,如果我这样做,jQuery会尝试在常规Table元素上执行函数,而不是在Table的dataTable转换上执行。 如果我尝试将DataTable()应用于上面的元素,我将得到:
未捕获的TypeError:无法读取未定义的属性'reload'
到目前为止,这是我的ajax调用(也没有用):
var idtable = $('.mydttable').attr('id');
$.ajax({
url: myFormAction,
type: 'POST',
cache: false,
data : { _token: csrf_token, _method:'DELETE' },
dataType: 'html',
success:function(data) {
$('#DeleteModalDialog').modal('hide');
if(idtable=='users'){
alert('uzerii');
uzTable.ajax.reload();
}else if(idtable=='clients'){
alert('Clients');
cliTable.ajax.reload();
}else if(idtable=='market'){
alert('Market');
marTable.ajax.reload();
}
}
});
因此即使我收到警报,重新加载也不会发生,因此它知道可见表的ID是什么。 (如上所示,uzTable,cliTable和marTable是jquery vars)
我的代码有什么问题......?我该如何解决?
答案 0 :(得分:2)
您需要使用服务器端处理。这是我如何做的一个例子。
$('.dtable').DataTable({
/*
* Shows message dialog of loading data for slow connections
*/
processing: true,
/*
* Does an ajax call to get the data
* Happens every time you search or sort
*/
serverSide: true,
/*
* full_numbers = first, last, next, previous, and numbers
* in the pagation
*/
pagingType: "full_numbers",
/*l = show X entries
* f = search box
* <> = div
* <"class" = class name
* t = table
* r = 'proccessing' dialog
* i = 10 out of 1000 records
* p = pagation
* */
dom: 'lf<"nstuff"p><"toolbar">trip',
/*
* Defines the ajax call
*/
ajax: {
url: 'url.php',
datatype: "json",
type: "post",
/*Adds data to ajax call*/
data: function(d) {
d.action = 'list';
}
},
/*Defines columns*/
columns: [
/* Everything in here is sent to server upon ajax call.
* Orderable false = no arrows to order by
* searchable false = doesn't search that column
* */
{
title: "name",
render: function() {
/*
* arguments[2] is the third parameter passed in through the
* function. it holds the entire row data in it.
*/
var row = arguments[2];
return "<a href='?" + row.id + "'>" + row.name + "</a>";
}
}, {
title: "Info",
"orderable": false,
render: function() {
return arguments[2].email;
}
}, {
title: "Action",
data: 'id',
"orderable": false
}
],
/*Orders from this to that*/
order: [
[0, 'asc']
]
});
<?php
function list($REQUEST) {
/*
* Draw is returned back to datatables in order for javascript to not render
* Older draws first in case of async ajax calls.
*/
$draw = $this->aspam($REQUEST, true, 'draw');
/* Query Handles the search field in the datatables plugin */
$query = $this->aspam($this->aspam($REQUEST, false, 'search'), false, 'value');
/* Data holds the extra variables */
$data = $this->aspam($REQUEST, false, 'data');
/* This is the array of order from datatables */
$order = $this->aspam($REQUEST, false, 'order');
/* Where to start the limit */
$start = $this->aspam($REQUEST, true, 'start');
/* how long the limit is */
$length = $this->aspam($REQUEST, true, 'length');
/* Set up all the variables defaults to not throw errors */
$orderby = '';
$where = '';
$first = TRUE;
/* if order is array itterate through it and set the order */
if (is_array($order)) {
foreach ($order as $o) {
if ($first) {
$first = FALSE;
} else {
$orderby .= ',';
}
/* 0 = Name
* $o[dir] is either asc or desc based on datatables
*/
switch ($o['column']) {
case 0:
case '0':
$orderby .= "entity_name $o[dir]";
break;
}
}
/* if not empty create the order by */
if (!empty($orderby)) {
$orderby = "ORDER BY $orderby";
}
}
/* if the search string is not empty search all the searchable fields */
if (!empty($query)) {
$where .= "
AND (
name like '%$query%'
)";
}
/* This is the selection query
* It creates the sql with out and with the where
*/
$sql_nowhere = ($sql = "
select from where
");
$sql_somewhere = ($sql .= "
$where
");
$sql .= "
$orderby
LIMIT $start,$length
";
/*
* after all the where and join clauses are created get the filtered
* count of all the records
*/
$recordsFiltered = $this->getCounts($sql_somewhere);
/* The total amount of records in this call */
$recordsTotal = $this->getCounts($sql_nowhere);
if (!$temp = $this->retrieve($sql)) {
/* if no results are shown create $temp as an empty array to not through errors */
$temp = [];
}
/* creates the datatables array that it likes so it won't through an error */
$array = array(
'draw' => $draw
, 'recordsTotal' => $recordsTotal
, 'recordsFiltered' => $recordsFiltered
, 'data' => $temp
);
return $array;
}
/**
* gets the total count of sql
* @param type $sql
* @return type
*/
function getCounts($sql) {
return $this->retrieve("SELECT count(*) as count FROM ($sql) as z")[0]['count'];
}
除此之外,我建议使用按钮上的点击事件来触发删除。
$('button').click(function() {
var id = $(this).data('id');
deleteMe(id).done(function() {
$('dtable').reload();
});
});
function deleteMe(id) {
/*code for what ever you do with the id.*/
return $.ajax();
}
<button data-id="555">
Me
</button>
这个脚本不会帮助你摆脱袖口,但它会指向正确的方向。
修改强>
var tables = [];
var options = [{
ajax: 1
}, {
ajax: 2
}, {
ajax: 3
}, {
ajax: 4
}, ];
$('dtable').each(function(index) {
$(this).data('id', index);
tables.push($(this).DataTables(options[index]));
});
$(document).on('click', '.ssDelete', function(e) {
var index = $(this).closest('dtable').data('id');
e.preventDefault();
$.ajax({
url: someFormAction,
type: 'POST',
dataType: 'html',
success: function(data) {
tables[index].ajax.reload();
}
});
});
<table class='dtable'></table>
<table class='dtable'></table>
<table class='dtable'></table>
<table class='dtable'></table>
每次执行数据表时,都会返回数据表句柄。您需要使用该句柄才能刷新表。我提出了一种方法,一次添加多个表,没有大量的冗余代码。只需确保您的options.length
和dtable.length
相同即可。否则你将通过并索引越界。
