使用 jQuery SimpleModal 插件的浮动窗口中的内容在 IE8 中打开两次后无法替换

我正在使用 SimpleModal 插件在浮动窗口中显示动态内容。在此浮动窗口上包含了 Javascript 函数调用(在单击事件上),这会更改此浮动窗口上的某些内容。

这对于 FF 来说非常有效。但是IE有一个问题(我只用IE8测试过): 仅当第一次在相应页面上打开此模式窗口时,使用 jQuery 在此 Javascript 函数中更改任何内容(或任何其他效果,如隐藏 DIV 等)才有效。在后续调用中,如果此浮动窗口在其间关闭,IE 将什么也不做!

看来 IE 不再识别某些 DOM 对象已更改并且应该呈现这些更改。当检查 DOM 对象的实际内容时,您会看到内容已更改,但只是没有渲染! :-(

我已经尝试过一些技巧,例如根元素上的 addClass('fake') / removeClass('fake') ,但没有成功。

这里有一些测试代码。

用于打开模态窗口的 Javascript 函数:

showTestModal('DEBUG', '<div id="DivTestRoot"><div id="DivTest">OrigValue</div><a href="javascript:changeContent(\'\',\'\');"">Click here</a></div>', 100, true, 50, 50);

Javascript 函数更改内容(从浮动窗口内调用):

function changeContent() {
    $('#DivTest').html('ChangedValue');
    $('#DivTestRoot').addClass('fake');
    $('#DivTestRoot').removeClass('fake');
    $('#DivTestRoot').show();
    alert($('#DivTest').parent()[0].innerHTML);

}

调用 jQuery SimpleModal 插件的相应代码:

function showTestModal(title, data, height, showClose, top, left) {
if (title == undefined)
    title = "";
if (data == undefined)
    data = "";
if (height != undefined)
    TestModal.height = height;
if (top == undefined)
    top = 135;
if (left == undefined)
    left = 20;
var closeHTML = "";
if (showClose == undefined || showClose == true)
    closeHTML = "<a href='#' title='Close' class='modalCloseX'>x</a>";
var htmlModal = "<div id='DivTestModal' style='display:none'><div class='TestModal-top'></div><div class='TestModal-content'><h1 class='TestModal-title'>"
    + title + "</h1><div class='TestModal-loading' style='display:none'></div><div class='TestModal-errormessage' style='display:none'></div>"
    + "<div class='TestModal-message'>" + data + "</div></div><div class='TestModal-bottom'></div></div>";
$(htmlModal).modal({
    closeHTML: closeHTML,
    position: [top, left],
    overlayId: 'TestModal-overlay',
    containerId: 'TestModal-container',
    onOpen: TestModal.open,
    onShow: TestModal.show,
    onClose: TestModal.close
});

}

这或多或少是从 http://www.ericmmartin.com/projects/simplemodal

var TestModal = {
message: null,
height: 0,
open: function(dialog) {
    //$(this).parent().appendTo("form");
    $(dialog).parent().appendTo("form");
    // add padding to the buttons in firefox/mozilla
    if ($.browser.mozilla) {
        $('#TestModal-container .TestModal-button').css({
            'padding-bottom': '2px'
        });
    }
    // input field font size
    if ($.browser.safari) {
        $('#TestModal-container .TestModal-input').css({
            'font-size': '.9em'
        });
    }
    var h = 280;
    if (TestModal.height > 0)
        h = TestModal.height;

    var title = $('#TestModal-container .TestModal-title').html();
    $('#TestModal-container .TestModal-title').html('Laden...');
    dialog.overlay.fadeIn(200, function() {
        dialog.container.fadeIn(200, function() {
            dialog.data.fadeIn(200, function() {
                $('#TestModal-container .TestModal-content').animate({
                    height: h
                }, function() {
                    $('#TestModal-container .TestModal-title').html(title);
                    $('#TestModal-container form').fadeIn(200, function() {
                        $('#TestModal-container #TestModal-name').focus();

                        // fix png's for IE 6
                        if ($.browser.msie && $.browser.version < 7) {
                            $('#TestModal-container .TestModal-button').each(function() {
                                if ($(this).css('backgroundImage').match(/^url[("']+(.*\.png)[)"']+$/i)) {
                                    var src = RegExp.$1;
                                    $(this).css({
                                        backgroundImage: 'none',
                                        filter: 'progid:DXImageTransform.Microsoft.AlphaImageLoader(src="' + src + '", sizingMethod="crop")'
                                    });
                                }
                            });
                        }
                    });
                });
            });
        });
    });
},
show: function(dialog) {
    $('#TestModal-container .TestModal-close').click(function(e) {
        e.preventDefault();
        if ($('#TestModal-container .TestModal-errormessage:visible').length > 0) {
            var msg = $('#TestModal-container .TestModal-errormessage div');
            msg.fadeOut(200, function() {
                msg.empty();
                contact.showError();
                msg.fadeIn(200);
            });
        }
        else {
            $('#TestModal-container .TestModal-errormessage').animate({
                height: '30px'
            }, contact.showError);
        }
    });
},
close: function(dialog) {
    $('#TestModal-container .TestModal-errormessage').fadeOut();
    $('#TestModal-container .TestModal-title').html('Schliessen...');
    $('#TestModal-container form').fadeOut(200);
    $('#TestModal-container .TestModal-content').animate({
        height: 40
    }, function() {
        dialog.data.fadeOut(200, function() {
            dialog.container.fadeOut(200, function() {
                dialog.overlay.fadeOut(200, function() {
                    $.modal.close();
                });
            });
        });
    });
},
error: function(xhr) {
    alert(xhr.statusText);
},
showError: function() {
    $('#TestModal-container .TestModal-errormessage')
   .html($('<div class="TestModal-error">').append(contact.message))
   .fadeIn(200);
}
};

第二次打开浮动窗口时,会在警告框中看到innerHTML已被适配,但仍然是在第一次尝试中,它总是显示值“ChangedValue”(“ChangedValue”显示在 DIV 中),

您的任何提示!

谢谢 罗杰

I am using SimpleModal plugin for showing dynamic content within a floating window. On this floating window a Javascript function call has been included (on a click event), which is changing some content on this floating window.

This works all very well with FF. But there is an issue with IE (I have tested with IE8 only):
Only at the very first time this modal window has been opened on corresponding page, changing any content (or any other effect like hiding DIVs etc.) from within this Javascript function using jQuery is working. On subsequent calls, if this floating window has been closed in between, IE will just do nothing!!!

It seems that IE does not recognize anymore that some DOM objects have been changed and that these changes should be rendered. When checking the actual content of the DOM object, you will see that the content has been changed, but it is just not rendered! :-(

I have already tried some hacks, like addClass('fake') / removeClass('fake') on a root element, but did not succeed.

Here some test code.

Javascript function for opening modal window:

showTestModal('DEBUG', '<div id="DivTestRoot"><div id="DivTest">OrigValue</div><a href="javascript:changeContent(\'\',\'\');"">Click here</a></div>', 100, true, 50, 50);

The Javascript function changing the content (called from within floating window):

function changeContent() {
    $('#DivTest').html('ChangedValue');
    $('#DivTestRoot').addClass('fake');
    $('#DivTestRoot').removeClass('fake');
    $('#DivTestRoot').show();
    alert($('#DivTest').parent()[0].innerHTML);

}

The corresponding code for calling jQuery SimpleModal plugin:

function showTestModal(title, data, height, showClose, top, left) {
if (title == undefined)
    title = "";
if (data == undefined)
    data = "";
if (height != undefined)
    TestModal.height = height;
if (top == undefined)
    top = 135;
if (left == undefined)
    left = 20;
var closeHTML = "";
if (showClose == undefined || showClose == true)
    closeHTML = "<a href='#' title='Close' class='modalCloseX'>x</a>";
var htmlModal = "<div id='DivTestModal' style='display:none'><div class='TestModal-top'></div><div class='TestModal-content'><h1 class='TestModal-title'>"
    + title + "</h1><div class='TestModal-loading' style='display:none'></div><div class='TestModal-errormessage' style='display:none'></div>"
    + "<div class='TestModal-message'>" + data + "</div></div><div class='TestModal-bottom'></div></div>";
$(htmlModal).modal({
    closeHTML: closeHTML,
    position: [top, left],
    overlayId: 'TestModal-overlay',
    containerId: 'TestModal-container',
    onOpen: TestModal.open,
    onShow: TestModal.show,
    onClose: TestModal.close
});

}

This is more or less the code copied from http://www.ericmmartin.com/projects/simplemodal:

var TestModal = {
message: null,
height: 0,
open: function(dialog) {
    //$(this).parent().appendTo("form");
    $(dialog).parent().appendTo("form");
    // add padding to the buttons in firefox/mozilla
    if ($.browser.mozilla) {
        $('#TestModal-container .TestModal-button').css({
            'padding-bottom': '2px'
        });
    }
    // input field font size
    if ($.browser.safari) {
        $('#TestModal-container .TestModal-input').css({
            'font-size': '.9em'
        });
    }
    var h = 280;
    if (TestModal.height > 0)
        h = TestModal.height;

    var title = $('#TestModal-container .TestModal-title').html();
    $('#TestModal-container .TestModal-title').html('Laden...');
    dialog.overlay.fadeIn(200, function() {
        dialog.container.fadeIn(200, function() {
            dialog.data.fadeIn(200, function() {
                $('#TestModal-container .TestModal-content').animate({
                    height: h
                }, function() {
                    $('#TestModal-container .TestModal-title').html(title);
                    $('#TestModal-container form').fadeIn(200, function() {
                        $('#TestModal-container #TestModal-name').focus();

                        // fix png's for IE 6
                        if ($.browser.msie && $.browser.version < 7) {
                            $('#TestModal-container .TestModal-button').each(function() {
                                if ($(this).css('backgroundImage').match(/^url[("']+(.*\.png)[)"']+$/i)) {
                                    var src = RegExp.$1;
                                    $(this).css({
                                        backgroundImage: 'none',
                                        filter: 'progid:DXImageTransform.Microsoft.AlphaImageLoader(src="' + src + '", sizingMethod="crop")'
                                    });
                                }
                            });
                        }
                    });
                });
            });
        });
    });
},
show: function(dialog) {
    $('#TestModal-container .TestModal-close').click(function(e) {
        e.preventDefault();
        if ($('#TestModal-container .TestModal-errormessage:visible').length > 0) {
            var msg = $('#TestModal-container .TestModal-errormessage div');
            msg.fadeOut(200, function() {
                msg.empty();
                contact.showError();
                msg.fadeIn(200);
            });
        }
        else {
            $('#TestModal-container .TestModal-errormessage').animate({
                height: '30px'
            }, contact.showError);
        }
    });
},
close: function(dialog) {
    $('#TestModal-container .TestModal-errormessage').fadeOut();
    $('#TestModal-container .TestModal-title').html('Schliessen...');
    $('#TestModal-container form').fadeOut(200);
    $('#TestModal-container .TestModal-content').animate({
        height: 40
    }, function() {
        dialog.data.fadeOut(200, function() {
            dialog.container.fadeOut(200, function() {
                dialog.overlay.fadeOut(200, function() {
                    $.modal.close();
                });
            });
        });
    });
},
error: function(xhr) {
    alert(xhr.statusText);
},
showError: function() {
    $('#TestModal-container .TestModal-errormessage')
   .html($('<div class="TestModal-error">').append(contact.message))
   .fadeIn(200);
}
};

When the floating window is opened the second time, you will see in the alert box that innerHTML has been adapted, but still the value "OrigValue" is shown. In the first attempt it is always working as it should ("ChangedValue" is shown within DIV).

Thank you for any hint!

Roger

抱歉我的措辞 - 昨天已经很晚了! ;-)

对问题的简短、希望更清晰的描述:

从 SimpleModal 窗口内调用 Javascript 函数。在此函数中,在此模式窗口中找到的一些内容将被替换 - 例如 $('#DivTest').html('ChangedValue')。

在 IE8 中,如果关闭并再次打开 SimpleModal 窗口,则无法再更改此模式窗口中的任何内容或将元素设置为不可见等。您可以看到 DOM 对象的内容和属性已更改,例如通过使用警报功能,但这些更改不会呈现。

FF 不会出现此问题。

干杯,
罗杰

Sorry for my wording - it was getting late yesterday! ;-)

The short, hopefully more clear description of the problem:

A Javascript function gets called from within a SimpleModal window. In this function some content found in this modal window is replaced - e.g. $('#DivTest').html('ChangedValue').

In IE8, if the SimpleModal window is closed and opened again, it is not possible anymore to change any content within this modal window or set elements to invisible etc.. You can see that content and attributes of DOM objects have been changed, in example by making use of alert function, but these changes are not rendered.

This problem does not occur with FF.

Roger

罗杰,

尝试将您的功能更改为:

function changeContent() {
    var container = $('#TestModal-container')[0];
    $('#DivTest', container).html('ChangedValue');
    //$('#DivTestRoot').addClass('fake'); // ? why add class then removeClass?
    //$('#DivTestRoot').removeClass('fake');
    $('#DivTestRoot', container).show();
    alert($('#DivTest', container).parent()[0].innerHTML);
}

我认为问题在于您绑定和访问内容的方式。如果这没有帮助,请告诉我。

-埃里克

Roger,

Try changing your function to:

function changeContent() {
    var container = $('#TestModal-container')[0];
    $('#DivTest', container).html('ChangedValue');
    //$('#DivTestRoot').addClass('fake'); // ? why add class then removeClass?
    //$('#DivTestRoot').removeClass('fake');
    $('#DivTestRoot', container).show();
    alert($('#DivTest', container).parent()[0].innerHTML);
}

I think the issue is with the way you are binding and accessing the content. Let me know if that does not help.

我发现 IE8 在关闭模态窗口后似乎没有正确删除 DOM 对象。

您可以在调试 Javascript 时看到,打开另一个模式窗口后,对象的旧值仍然存在,但渲染的内容不同!在这种情况下,IE8“决定”不对这些对象执行任何操作。

SimpleModal jQuery 插件的 $.modal.close() 函数在关闭模态窗口时被调用。在 FF 中,所有 DOM 对象似乎都从内存中正确删除,但在 IE8 中则不然。

在这些发现之后,我决定实施一种不同的方法 - 模式窗口和标准 aspx 页面中的 iFrame。效果很好。

干杯,
罗杰

I found out that IE8 does'nt seem to remove DOM objects correctly after closing modal window.

You could see when debugging Javascript that after opening another modal window, old values are still there for the objects, but different content gets rendered! In this situation IE8 "decides" to just do nothing with these objects.

$.modal.close() function of SimpleModal jQuery plugin gets called when closing modal window. In FF all DOM objects seem to be removed correctly from memory, but in IE8 not.

After these findings I decided to implement a different approach - an iFrame within modal window and standard aspx page. Works great.

Cheers,
Roger
