Prevent text selection on mouse drag
提问by RandomClown
How can I prevent text selection withoutusing the traditional method e.stopPropagation(related question at bottom)?
Is there a call I can make to say "unhighlight whatever is highlighted"?
如何在不使用传统方法的情况下防止文本选择e.stopPropagation（底部的相关问题）？
是否可以打电话说“取消突出显示的任何内容”？
I bound mouse events on the document because there are about a hundred [more or less] elements in the page that I want to have interact with each other.
我在文档上绑定了鼠标事件，因为页面中有大约一百个 [或多或少] 元素我希望彼此交互。
The reason I don't bind events to the elements instead is because when the mouse moves off the element, all mouse events stop triggering. I need to bind to the document to correctly watch mouse events.
我不将事件绑定到元素的原因是因为当鼠标移离元素时，所有鼠标事件都会停止触发。我需要绑定到文档才能正确观看鼠标事件。
The problem with using the method traditional method (link below) is that by the time the listener is triggered, the elements with text has already evaluated the mouse event.
使用传统方法（下面的链接）的问题在于，在触发侦听器时，带有文本的元素已经评估了鼠标事件。

I believe that this answer, along with the CSS answer above, will produce the result you're looking for. Here is a solution that works cross-browser.

if (document.selection) {
document.selection.empty()
} else {
window.getSelection().removeAllRanges()
}
}
called onmouseupand onmousemovedoes the trick.
