jQuery - 动态添加按钮单击无法正常工作

Question

我编写了以下代码,创建了一个带有动态添加内容的弹出窗口.现在我想删除这些添加的项目或编辑它们,但它似乎没有点击其中一个按钮的事件(btnLSM_Remove + btnLSM_Edit).任何线索为什么会这样？btnLSM_Add并btnLSM_Okay以同样的方式工作,他们工作......

function ListManagementDialog(obj, dialogTitle, dialogText, listDelimiter, btnNames) {
    if (!$.isArray(btnNames)) {        
        return false;
    }

     if (dialogConfirmed) {
        return false;
    }

    btns[btnNames[0]] = function () {
        $(this).dialog('close');
        dialogConfirmed = true;
        if (obj) {
            obj.click();
        }
    };

    btns[btnNames[1]] = function () {
        $(this).dialog('close');
    };



    $('body').append(String.Format('<div id="divLSM_Dialog" title="{0}"><p>{1}</p>' +
        '<button id="btnLSM_Add" class="btnAdd" type="button" role="button" aria-disabled="false" title="Hinzuf&#252;gen" />' +               
        '<input id="txbLSM_Emailadresse" class="text ui-widget-content ui-corner-all" type="text" name="txbLSM_Emailadresse" style="display:none;">' +
        '<button id="btnLSM_Okay" class="btnOkay" type="button" role="button" aria-disabled="false" title="&#220;bernehmen" style="display:none;" />' +
        '<br /><br />' +
        '<table id="tblLSM_Items" class="ui-widget ui-widget-content">' +
                 '<thead>' +
                        '<tr class="ui-widget-header ">' +
                '<th>Emailadresse</th>' +
                '<th />' +
                '</tr>' +
            '</thead>' +
            '<tbody />' +
        '</table>' +
        '</div>', dialogTitle, dialogText));

    $('#btnLSM_Add').click(function () {
        $('#txbLSM_Emailadresse').val('');
        $('#txbLSM_Emailadresse').show();
        $('#btnLSM_Okay').show();
        $('#txbLSM_Emailadresse').focus();
    });  

    $('#btnLSM_Okay').click(function () {
        $('#tblLSM_Items tbody').append('<tr>' +
            '<td>' + $('#txbLSM_Emailadresse').val() + '</td>' +
            '<td>' + '<button id="btnLSM_Remove" class="btnRemove" type="button" role="button" aria-disabled="false" title="Entfernen" />' + '<button id="btnLSM_Change" class="btnEdit" type="button" role="button" aria-disabled="false" title="&#196;ndern" />' + '</td>' +
            '</tr>');

        $('#txbLSM_Emailadresse').hide();
        $('#btnLSM_Okay').hide();
    });

    $('#btnLSM_Remove').click(function () {
        alert("hohoho"); //no alert-popup
    });   

     $('#btnLSM_Change').click(function () {
        alert("hohoho"); //no alert-popup
    });

    $('#divLSM_Dialog').dialog({
        modal: true,
        resizable: false,
        draggable: true,
        width: 600,
        height: 300,
        close: function (event, ui) {
            $('body').find('#divLSM_Dialog').remove();
        },
        buttons: btns
    });

    return dialogConfirmed;
}

Answer 1

您致电时,您的btnLSM_Remove按钮不存在

$('#btnLSM_Remove').click(function () {

所以$('#btnLSM_Remove')集合是空的,处理程序被添加到任何东西.

你可以使用on函数:

$('#divLSM_Dialog').on('click', '#btnLSM_Remove', function () {

注册将应用于委托定义之后出现的按钮的处理程序.

编辑:

在jQuery 1.6.2中,您可以使用live:

$('#btnLSM_Remove').live('click', function () {
