将click事件绑定到jQuery Datatable on()中的tr元素不起作用 [英] Binding a click event to tr elements in jQuery Datatable on() doesn't work

问题描述

我正在开发一个表，其中将包含我们所有的用户，也可以通过单击表行并以单击后打开的形式编辑数据来进行更改.

I am developing a table that will contain all our users which can also be changed by clicking the tablerow and editing the data in a form that will open once the click was performed.

如果我在页面加载时加载了所有用户，则我的代码可以正常工作.

If i have all the users loaded at page load, my code works fine.

一旦我更改了数据表以在数据表初始化时加载用户，它将仅在第一页上工作.

Once i change my datatable to load the users at datatable initialisation it will only work on the first page.

如果我取消注释ready(function())的下部并删除fnInitComplete，它将甚至无法在首页上显示.

If i uncomment the lower part of my ready(function()) and delete fnInitComplete it wont even work on the first page.

这是我的代码的相关部分:

Here is the relevant part of my code:

        $(document).ready(function(){
            tbl = $('#nutzer').dataTable( {
                "bJQueryUI": true,
                "sScrollX": "100%",
                "bProcessing": true,
                "bServerSide": true,
                "iDisplayLength": 10,
                "sAjaxSource": "xhr.php",
                "sPaginationType": "full_numbers",
                "fnInitComplete": function() {
                    $('#nutzer tbody tr').on("click", function () {
                        aufklappen(this);
                    } );
                }
            } );

            $( "#create-user" ).button().click(function() {
                $( "#dialog-form" ).dialog( "open" );
            });
//            $('#nutzer tbody tr').on("click", function () {
//                aufklappen(this);
//            } );
        });

        function aufklappen(row) {
            if ( tbl.fnIsOpen(row) ) {
                tbl.fnClose(row);
            } else {
                set = tbl.fnSettings().aoOpenRows[0];
                (set != null) ? (tbl.fnClose(set.nParent)) : null;
                $.post("benutzerBearbeiten.php", { 
                    funktion : "benutzerDaten",
                    id : $(row).children( "td:first-child" ).text()
                }, function(data){
                    tbl.fnOpen( row, data);
                    $( "#deaktivieren").button().click(function(e){
                        e.preventDefault();
                        deaktivieren();
                    });
                    $( "#speichern").button().click(function(e){
                        e.preventDefault();
                        speichern();
                    });
                }
            ) };
        }

在通过数据表分页进行页面加载或页面更改后，我可以手动调用

After page load or page change through the datatables pagination i can manualy call

$('#nutzer tbody tr').on('click', function () {
    aufklappen(this);
} );

和click函数完美地绑定到tr.

and the click function gets bound to the tr's perfectly.

在我看来，由datatables-plugin创建的元素并未使dom进入我定义的on()处理程序，但我不知道为什么.

Seems to me that the elements created by datatables-plugin are not getting up the dom to the on() handler that i defined but i cant figure out why.

利用系统重新启动"的答案，我最终删除了fnInitComplete部分并添加

Utilising "The System Restart"s answer i ended up deleting the fnInitComplete part and add

"asStripeClasses": [ "odd nutzer_tr", "even nutzer_tr"]

到初始化部分，然后

$("body").delegate(".nutzer_tr", "click", function () {
    aufklappen(this);
});

到ready(function()).附加的类nutzer_tr是为了防止打开的表行关闭.

to the ready(function()). The additional class nutzer_tr is to prevent the opened tablerow from closing.

推荐答案

我认为您需要现场直播:

I think you need live event:

$('body').on('click', '#nutzer tbody tr', function () {
    aufklappen(this);
});

或可以使用委托()

$('body').delegate('#nutzer tbody tr', 'click', function () {
    aufklappen(this);
});
