Jquery IE9中的灰度缩放

Jquery IE9中的灰度缩放,jquery,internet-explorer-9,grayscale,Jquery,Internet Explorer 9,Grayscale,我的画廊有问题,我不知道如何解决。 根据本网站的推荐,我对照片使用灰度效果http://webdesignerwall.com/demo/html5-grayscale/ 在FF和Chrome中,一切都很好,但在IE中,所有图像都没有正确重叠显示 我的代码是: function grayscale(src){ var canvas = document.createElement('canvas'); var ctx = canvas.getContext

我的画廊有问题,我不知道如何解决。 根据本网站的推荐,我对照片使用灰度效果http://webdesignerwall.com/demo/html5-grayscale/ 在FF和Chrome中,一切都很好,但在IE中,所有图像都没有正确重叠显示

我的代码是:

    function grayscale(src){
        var canvas = document.createElement('canvas');
        var ctx = canvas.getContext('2d');
        var imgObj = new Image();
        imgObj.src = src;
        canvas.width = imgObj.width;
        canvas.height = imgObj.height; 
        ctx.drawImage(imgObj, 0, 0); 
        var imgPixels = ctx.getImageData(0, 0, canvas.width, canvas.height);
        for(var y = 0; y < imgPixels.height; y++){
            for(var x = 0; x < imgPixels.width; x++){
                var i = (y * 4) * imgPixels.width + x * 4;
                var avg = (imgPixels.data[i] + imgPixels.data[i + 1] + imgPixels.data[i + 2]) / 3;
                imgPixels.data[i] = avg; 
                imgPixels.data[i + 1] = avg; 
                imgPixels.data[i + 2] = avg;
            }
        }
        ctx.putImageData(imgPixels, 0, 0, 0, 0, imgPixels.width, imgPixels.height);
        return canvas.toDataURL();
    }
                // Fade in images so there isn't a color "pop" document load and then on window load

    $(".item img").animate({opacity:1},0);

    // clone image
    $('a.thumb img').each(function(){
        var el = $(this);
        el.css({"position":"absolute"}).wrap("<div class='img_wrapper' style='display: inline-block'>").clone().addClass('img_grayscale').css({"position":"absolute","z-index":"998","opacity":"0"}).insertBefore(el).queue(function(){
            var el = $(this);
            el.parent().css({"width":this.width,"height":this.height});
            el.dequeue();
        });
        this.src = grayscale(this.src);
    });

    // Fade image 
    $('a.thumb img').mouseover(function(){
        $(this).parent().find('img:first').stop().animate({opacity:1}, 0);
    })
    $('.img_grayscale').mouseout(function(){
        $(this).stop().animate({opacity:0}, 0);
    });
我还附上了一张图片,上面有IE9中显示的照片http://postimage.org/image/8w0hnqnbl/
提前谢谢

不使用脚本时是否也会发生这种情况?你能发布一个测试用例/提琴吗?我认为你的问题在于显示:内联块,检查IE9是否在兼容性或怪癖模式下渲染?也许不是你想要的答案,但是试着用float:left或使位置相对,看看这有什么帮助。不可能用float:left或position-relative。
