Question

在我们的登台服务器上遇到Jcrop失败但在生产中工作正常的问题。

两个环境都在相同的硬件上运行，设置了apache虚拟主机。从我们可以看出，环境是相同的。以下是选择要上传的图片后加载的模式框中的代码。

<?php $jsIncludes = array(
    "jQuery-File-Upload-and-Crop-plugin/js/vendor/jquery.ui.widget",

    "jQuery-File-Upload-and-Crop-plugin/js/load-image.min",
    "jQuery-File-Upload-and-Crop-plugin/js/main"
    );
echo $this->html->script($jsIncludes); 
?>

        Click and drag over the area of the phone you'd like to use as your profile picture.

        <a href="#" class="btn btn-primary" id="btnDoCrop">Crop</a>
    </div>
</div>

任何人都知道为什么这可能适用于一个环境但不适用于另一个环境？

我们最终在IE8下的暂存环境中得到的是一张正确裁剪的图像，但无论源图像如何，它都是黑色的。

Answer 1

这是一个古老的悬而未决的问题，但万一有人来自Google搜索，答案就是不必担心IE8。死了如果客户需要IE8支持，请向客户显示一条消息，告知他们需要下载现代浏览器。

Jcrop在特定服务器上的IE8下失败，可以在另一台服务器上运行
