嗨，我是DataTables的新手....我有一个数据表，我想在其中添加行（一次一个），并具有多行删除的功能。我设法使正常功能正常工作，但是问题是当我删除一行/行然后尝试添加新行时，已删除的行又出现在与选定行相同的位置上....以下是代码i正在用于初始化DataTable以及在DataTable中添加和删除行的功能...。任何帮助将不胜感激...
$(document).ready(function (){
var counter = 1
$('#addRow').on( 'click', function (a,b,c,d,e,f) {
a = "test"
t.row.add( [
counter +a,
counter +'test',
counter +'test',
counter +'test',
counter +'test',
counter +'test'
] ).draw(false);
counter ++;
} );
$('#example tbody').on( 'click', 'tr', function (e) {
if ( $(this).hasClass('selected') ) {
$(this).removeClass('selected');
$(this).css('background-color', '')
}
else {
t.$('tr.selected');//.removeClass('selected');
$(this).addClass('selected');
$(this).css('background-color', 'blue');
}
} );
$('#removeRow').click( function () {
var anSelected = fnGetSelected( t );
$(anSelected).remove();
} );
var t = $('#example').DataTable({
'fnCreatedRow': function (nRow, aData, iDataIndex) {
$(nRow).attr('id', 'my' + iDataIndex);
},
"aoColumnDefs": [ {
"aTargets": [0,1,2,3,4,5],
"fnCreatedCell": function (nTd, sData, oData, iRow, iCol) {
var idx = t.cell( nTd ).index().column;
var title = t.column( idx ).header();
$(nTd).attr("id",$(title).html() +"_"+ iRow)
}
} ]
});
});
function fnGetSelected( oTableLocal )
{
return oTableLocal.$('tr.selected');
}
上面的代码只是为了测试功能，其中包括一些不需要的内容。...
****帖子更新****表格html是用模板编写的，我正在表单内调用...带有表单代码的父gsp文件在下面...
主gsp文件
<g:form action="saveTravelDetails" id="createRequest" name="createRequest" autocomplete="off">
<g:render template="newTravelRequest" />
<div class="row">
<div class="col-md-12">
<div class="form-group" style="text-align: center;">
<input id="circuit_save" class="btn btn-primary circuit_validate" tabindex="700" class="button_text" type="submit" name="circuit_save" value="Save" />
<input id="circuit_cancel" class="btn btn-default" class="button_text" type="button" name="circuit_cancel" value="Cancel" />
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#detailsModal">Add new row</button>
<button type="button" class="btn btn-primary" id="removeRow">Remove Selected Row</button>
</div>
</div>
</div>
</g:form>
模板html代码如下
<div class="row">
<div class="col-md-12">
<div class="panel panel-default">
<div class="panel-heading">
<i class="fa fa-user"></i> Travel Details
<div class="panel-tools">
<a href="#" class="btn btn-xs btn-link panel-collapse collapses">
</a>
</div>
</div>
<div class="panel-body">
<table cellpadding="0" cellspacing="0" border="0" class="display" id="example">
<thead class="alignCenter">
<tr>
<th class="headerclass">Departure Date</th>
<th class="headerclass">Return Date</th>
<th class="headerclass">Departure Destination</th>
<th class="headerclass">Arrival Destination</th>
<th class="headerclass">Choose Mode Of Transport</th>
<th class="headerclass">Cost of Travel</th>
</tr>
</thead>
<tbody></tbody>
<tfoot class="alignCenter headerclass">
<tr>
<th class="headerclass">Departure Date</th>
<th class="headerclass">Return Date</th>
<th class="headerclass">Departure Destination</th>
<th class="headerclass">Arrival Destination</th>
<th class="headerclass">Choose Mode Of Transport</th>
<th class="headerclass">Cost of Travel</th>
</tr>
</tfoot>
</table>
</div>
</div>
</div>
</div>
主文件中用于初始化DataTable的更新的javascript代码在下面给出...这也具有添加和删除行的功能定义
$(document).ready(function (){
var counter = 1
$('#addRow').on( 'click', function () {
t.row.add( [
$('#departureDate_1').val(),
$('#returnDate_1').val(),
$('#startDestination').val(),
$('#endDestination').val(),
$('#travelMode').val(),
$('#travelFare').val(),
] ).draw(false);
counter ++;
$('#detailsModal').modal('hide');
} );
$('#example tbody').on( 'click', 'tr', function (e) {
if ( $(this).hasClass('selected') ) {
$(this).removeClass('selected');
$(this).css('background-color', '')
}
else {
t.$('tr.selected');//.removeClass('selected');
$(this).addClass('selected');
$(this).css('background-color', 'blue');
}
} );
$('#removeRow').click( function () {
var anSelected = fnGetSelected( t );
$(anSelected).remove();
} );
var t = $('#example').DataTable({
'fnCreatedRow': function (nRow, aData, iDataIndex) {
$(nRow).attr('id', 'my' + iDataIndex);
$(nRow).attr('name', 'my' + iDataIndex); // or whatever you choose to set as the id
},
"aoColumnDefs": [ {
"aTargets": [0,1,2,3,4,5],
"fnCreatedCell": function (nTd, sData, oData, iRow, iCol) {
var idx = t.cell( nTd ).index().column;
var title = t.column( idx ).header();
$(nTd).attr("name",$(title).html() +"_"+ iRow)
$(nTd).attr("id",$(title).html() +"_"+ iRow)
}
} ]
});
$('#departureDate').on('change',function (){
$('.bootstrap-datetimepicker-widget').css('display','none');
});
$('#returnDate').on('change',function (){
$('.bootstrap-datetimepicker-widget').css('display','none');
});
$('#departureDate').datetimepicker({
format: 'YYYY-MM-DD',
pick12HourFormat: false,
autoclose: true
});
$('#returnDate').datetimepicker({
format: 'YYYY-MM-DD',
pick12HourFormat: false,
autoclose: true
});
});
function fnGetSelected( oTableLocal )
{
return oTableLocal.$('tr.selected');
}
提前致谢
感谢您阅读我的问题并花时间回答它，我找到了解决方案...以下是可在其他情况下使用的代码....
$('#removeRow').click(function() {
var anSelected = fnGetSelected(t);
alert(anSelected);
t.row(anSelected).remove().draw(false);
});
function fnGetSelected(oTableLocal) {
return oTableLocal.$('tr.selected');
}
