问题描述
我有绘图应用程序，允许用户在画布上绘制各种形状。代码在Chrome，IE 10，IE 9（9.0.8112.16421）上经过测试并正常运行，但它在IE 9（9.0.8112.16421 64位版本）上显示出荒谬的行为。主要问题是图像未在画布上绘制（一段时间）。无法弄清楚原因，如果我开始调试或在加载图像和在画布上绘制它们之间设置警报然后它正常工作。图像之类的图像没有完全加载，但如果这是原因那么它应该在IE 9版本中表现相似不是64位版本。任何线索如何处理这个问题???
I have drawing application where users are allowed to draw various shapes on canvas. Code is tested and working properly on Chrome,IE 10,IE 9(9.0.8112.16421), however it's showing absurd behavior on IE 9(9.0.8112.16421 64-bit edition).The main issue is images are not getting drawn on canvas(sometime). Unable to figure out the reason, if i start debugging or put alerts between loading images and drawing them on canvas then it works properly.Seems like images are not getting loaded fully but if that's the reason then it should behave similar in IE 9 version which is not 64-bit edition. Any clue how to handle this problem???
