IE 10拖放上传给空的dataTransfer [英] IE 10 drag and drop upload gives empty dataTransfer
问题描述
dragCatcher.on（'drop'，function（e）{
e.preventDefault（）;
e.stopPropagation（）;
console.log（e.originalEvent.dataTransfer。文件）;
}）。on（'dragenter'，function（e）{
e.preventDefault（）;
e.stopPropagation（）;
}）。 'dragleave'，function（e）{
e.preventDefault（）;
e.stopPropagation（）;
}）。on（'dragover'，function（e）{
e.preventDefault（）;
e.stopPropagation（）;
console.log（e.originalEvent.dataTransfer.types）;
}）;
console.log 未定义。我可以确认它不是控制台错误，因为 e.originalEvent.dataTransfer.files [0] 出现错误。我确定我缺少一些明显的东西，但我似乎无法弄清楚。
我有同样的问题今天调试5个小时后，我从我的< head>
< meta http-equiv =X-UA-Compatiblecontent =IE = 9/>
在我将其更改为IE = 10后，问题解决了。 （确保重新启动您的IE）
希望这也可以解决您的问题。
I have some drag and drop upload code that isn't working properly in IE 10. My event handlers look something like this:
dragCatcher.on('drop', function (e) {
e.preventDefault();
e.stopPropagation();
console.log(e.originalEvent.dataTransfer.files);
}).on('dragenter', function (e) {
e.preventDefault();
e.stopPropagation();
}).on('dragleave', function (e) {
e.preventDefault();
e.stopPropagation();
}).on('dragover', function (e) {
e.preventDefault();
e.stopPropagation();
console.log(e.originalEvent.dataTransfer.types);
});
Both console.log's come up with undefined. I can confirm it's not a console bug, as e.originalEvent.dataTransfer.files[0] comes up with an error. I'm sure I'm missing something obvious, but I can't seem to figure it out.
I had the same problem today. After 5 hours debugging, I found this from my<head>
<meta http-equiv="X-UA-Compatible" content="IE=9" />
After I change it to IE=10, problem solved. (Make sure you restart your IE)
Hopefully, this can solve your problem too.
