JQuery 切换功能在 IE 中呈现奇怪的文本(丢失 ClearType?) [英] JQuery toggle function rendering weird text in IE (losing ClearType?)

问题描述

我有这个小脚本可以在单击按钮时切换联系表单:

I have this little script to toggle a contact form when a button is clicked :

$(document).ready(function(){

    $("#button").click(function () {
      $("#form").toggle("slow");
    });

});

在 Firefox 中一切正常，但在 IE 中似乎切换的淡入效果没有 100% 完成，并且文本在完成渲染之前被冻结"在某处，失去了所有的精细分辨率.

All is working OK in Firefox, but in IE it seems like the toggle's fade-in effect doesn't gets 100% complete, and the text is being 'frozen' somewhere before a complete render, loosing all its fine resolution.

我读了这个主题，但我不知道如何将它应用到我的问题.

I read this topic but I don't know exactly how to apply it to my issue.

感谢您的帮助.

推荐答案

这可能就是您要找的.此外，还有一个另一种类似方法的功能演示在线提供.:

This may be what you're looking for. Also, there is a functional demo of another similar method available online.:

//-------------------------------------------------------------------------------------------------------
// ClearTypeFadeTo / ClearTypeFadeIn / ClearTypeFadeOut
//
// Custom fade in and fade out functions for jQuery that will work around
// IE's bug with bold text in elements that have opacity filters set when
// also using Window's ClearType text rendering.
//
// New Parameter:
// bgColor    The color to set the background if none specified in the CSS (default is '#fff')
//
// Examples:
// $('div').ClearTypeFadeIn({ speed: 1500 });
// $('div').ClearTypeFadeIn({ speed: 1500, bgColor: '#ff6666', callback: myCallback });
// $('div').ClearTypeFadeOut({ speed: 1500, callback: function() { alert('Fade Out complete') } });

(function($) {
    $.fn.ClearTypeFadeTo = function(options) {
        if (options)
            $(this)
                .show()
                .each(function() {
                    if (jQuery.browser.msie) {
                        // Save the original background color
                        $(this).attr('oBgColor', $(this).css('background-color'));
                        // Set the bgColor so that bold text renders correctly (bug with IE/ClearType/bold text)
                        $(this).css({ 'background-color': (options.bgColor ? options.bgColor : '#fff') })
                    }
                })
                .fadeTo(options.speed, options.opacity, function() {
                    if (jQuery.browser.msie) {
                        // ClearType can only be turned back on if this is a full fade in or
                        // fade out. Partial opacity will still have the problem because the
                        // filter style must remain. So, in the latter case, we will leave the
                        // background color and 'filter' style in place.
                        if (options.opacity == 0 || options.opacity == 1) {
                            // Reset the background color if we saved it previously
                            $(this).css({ 'background-color': $(this).attr('oBgColor') }).removeAttr('oBgColor');
                            // Remove the 'filter' style to restore ClearType functionality.
                            $(this).get(0).style.removeAttribute('filter');
                        }
                    }
                    if (options.callback != undefined) options.callback();
                });
    };

    $.fn.ClearTypeFadeIn = function(options) {
        if (options)
            $(this)
                .css({ opacity: 0 })
                .ClearTypeFadeTo({ speed: options.speed, opacity: 1, callback: options.callback });
    };

    $.fn.ClearTypeFadeOut = function(options) {
        if (options)
            $(this)
                .css({ opacity: 1 })
                .ClearTypeFadeTo({ speed: options.speed, opacity: 0, callback: options.callback });
    };
})(jQuery);
