HTML5 Drag&Drop issue in Internet Explorer (dataTransfer property access not possible)
提问by netik
I'm trying to implement basic drag&drop functionality with HTML5. It works totally fine in Chrome, but in IE10 I get an 0x8000ffff - JavaScript runtime error: Unexpected call to method or property access.error in the line setData.
我正在尝试使用 HTML5 实现基本的拖放功能。它在 Chrome 中完全正常，但在 IE10 中，我0x8000ffff - JavaScript runtime error: Unexpected call to method or property access.在行中出现错误setData。
function handleDragStart(e) {
e.dataTransfer.effectAllowed = 'move';
e.dataTransfer.setData("dropTarget", g.destination);
}
var cols = $("#" + g.source + " tbody > tr");
[].forEach.call(cols, function (col) {
col.addEventListener('dragstart', handleDragStart, false);
});
What am I doing wrong?
我究竟做错了什么？

For those who are looking for an answer:
对于那些正在寻找答案的人：
getData() and setData() attribute must be called exactly "text", since u can use any parameter in other browsers (which actualy makes lot of sense - IE rocks again), those other answers here are useless.
getData() 和 setData() 属性必须准确地称为“文本”，因为您可以在其他浏览器中使用任何参数（这实际上很有意义 - IE 再次摇滚），这里的其他答案无用。

You are right. In IE 11 I changed from e.dataTransfer.getData('text/html') to e.dataTransfer.getData('text') and no Errors occur. Dto. in e.dataTransfer.setData('text').
你说的对。在 IE 11 中，我从 e.dataTransfer.getData('text/html') 更改为 e.dataTransfer.getData('text') 并且没有发生错误。托。在 e.dataTransfer.setData('text') 中。
This sample (the DnD methods) will then run in IE 11, Chrome and Firefox: http://www.developer.com/lang/using-html5-drag-and-drop-in-asp.net.html
此示例（DnD 方法）将在 IE 11、Chrome 和 Firefox 中运行：http: //www.developer.com/lang/using-html5-drag-and-drop-in-asp.net.html

Looks like I misunderstood the purpose of dataTransfer.setData.
看来我误解了dataTransfer.setData.
It works only like this:
它的工作原理是这样的：
e.dataTransfer.setData("Text", g.destination);
e.dataTransfer.setData("Text", g.destination);
