如何在jquery的datatable插件中获取列id我需要在数据库中更新列id。

上面的代码片段实际上帮助我针对我的特定情况解决了这个问题。下面是我的代码:
// My DataTable
var oTable;
$(document).ready(function() {
/* You might need to set the sSwfPath! Something like:
* TableToolsInit.sSwfPath = "/media/swf/ZeroClipboard.swf";
*/
TableToolsInit.sSwfPath = "../../Application/JqueryPlugIns/TableTools/swf/ZeroClipboard.swf";
oTable = $('#tblFeatures').dataTable({
// "sDom": '<"H"lfr>t<"F"ip>', // this is the standard setting for use with jQueryUi, no TableTool
// "sDom": '<"H"lfrT>t<"F"ip>', // this adds TableTool in the center of the header
"sDom": '<"H"lfr>t<"F"ip>T', // this adds TableTool after the footer
// "sDom": '<"H"lfrT>t<"F"ip>T', // this adds TableTool in the center of the header and after the footer
"oLanguage": { "sSearch": "Filter this data:" },
"iDisplayLength": 25,
"bJQueryUI": true,
// "sPaginationType": "full_numbers",
"aaSorting": [[0, "asc"]],
"bProcessing": true,
"bStateSave": true, // remembers table state via cookies
"aoColumns": [
/* CustomerId */{"bVisible": false },
/* OrderId */{"bVisible": false },
/* OrderDetailId */{"bVisible": false },
/* StateId */{"bVisible": false },
/* Product */null,
/* Description */null,
/* Rating */null,
/* Price */null
]
});
// uncomment this if you want a fixed header
// don't forget to reference the "FixedHeader.js" file.
// new FixedHeader(oTable);
});
// Add a click handler to the rows - this could be used as a callback
// Most of this section of code is from the DataTables.net site
$('#tblFeatures tr').click(function() {
if ($(this).hasClass('row_selected')) {
$(this).removeClass('row_selected');
}
else {
$(this).addClass('row_selected');
// Call fnGetSelected function to get a list of selected rows
// and pass that array into fnGetIdsOfSelectedRows function.
fnGetIdsOfSelectedRows(fnGetSelected(oTable));
}
});
function fnGetSelected(oTableLocal) {
var aReturn = new Array();
// fnGetNodes is a built in DataTable function
// aTrs == array of table rows
var aTrs = oTableLocal.fnGetNodes();
// put all rows that have a class of 'row_selected' into
// the returned array
for (var i = 0; i < aTrs.length; i++) {
if ($(aTrs[i]).hasClass('row_selected')) {
aReturn.push(aTrs[i]);
}
}
return aReturn;
}
// This code is purposefully verbose.
// This is the section of code that will get the values of
// hidden columns in a datatable
function fnGetIdsOfSelectedRows(oSelectedRows) {
var aRowIndexes = new Array();
var aRowData = new Array();
var aReturn = new Array();
var AllValues;
aRowIndexes = oSelectedRows;
// The first 4 columns in my DataTable are id's and are hidden.
// Column0 = CustomerId
// Column1 = OrderId
// Column2 = OrderDetailId
// Column3 = StateId
// Here I loop through the selected rows and create a
// comma delimited array of id's that I will be sending
// back to the server for processing.
for(var i = 0; i < aRowIndexes.length; i++){
// fnGetData is a built in function of the DataTable
// I'm grabbing the data from rowindex "i"
aRowData = oTable.fnGetData(aRowIndexes[i]);
// I'm just concatenating the values and storing them
// in an array for each selected row.
AllValues = aRowData[0] + ',' + aRowData[1] + ',' + aRowData[2] + ',' + aRowData[3];
alert(AllValues);
aReturn.push(AllValues);
}
return aReturn;
}

下面是一个如何在单击行后获取id的示例
$('#example tbody tr').live('click', function() {
var row = example .fnGetData(this);
id=row['id'];//or row[0] depend of situation
function(id);
});
如果你需要一个表中的所有id,你必须使用这样的代码:
$(exampleTable.fnGetNodes()).each(function() {
var aPos = exampleTable.fnGetPosition(this);
var aData = exampleTable.fnGetData(aPos[0]);
aData[aPos[0]] = this.cells[0].innerHTML;
IdSet.push(aData[aPos[0]]);
});
希望能帮上忙!

像这样一个简单的问题需要一个很好的简单的jQuery解决方案。
假设您的id在第0行,并且您希望在对第5行执行操作时访问它,例如
$('td:eq(5)').click(function (){
var id = $(this).parent().find('td:eq(0)').html();
alert('The id is ' + id);
});
注意:这也适用于过滤器和分页结果。
我同意@fbas的说法,通常的答案并不是很有帮助。
