我有一个使用 ImgAreaSelect (v0.9.10) 的应用程序我的问题是它在 FF、Chrome、mac 和 pc 中运行良好。IE 10 似乎有一个零星的裁剪问题。

我想不明白。当您使用预览框加载图像然后尝试裁剪时，裁剪工具并不总是有效。这似乎是非常零星的问题，只发生在 IE 10 上。

这是页面代码。

什么会导致 IE 10 不允许裁剪工作，有什么想法吗？

谢谢

调用两次是没有意义的$('#photo').imgAreaSelect()，所以将所有选项合并到一个实例中......

$(document).ready(function () {

    $('#photo').imgAreaSelect({
        aspectRatio: '1:1',
        handles: true,
        fadeSpeed: 200,
        minHight: 200,
        minHeight: 200,
        x1: 0,
        y1: 0,
        x2: 200,
        y2: 200,
        onSelectChange: preview,
        onSelectEnd: function (img, selection) {
            $('input[name=x1]').val(selection.x1);
            $('input[name=y1]').val(selection.y1);
            $('input[name=x2]').val(selection.x2);
            $('input[name=y2]').val(selection.y2);
        }
    });

});
