How can I deselect text using Javascript or jQuery?
提问by Leo Jiang
I have a draggable (jQuery UI) element with "canceled" text on it. Here's what I mean:
我有一个带有“已取消”文本的可拖动（jQuery UI）元素。这就是我的意思：
$('#main').draggable({
cancel: '#main>* *',
start: function(){
// deselect text
}
});
When I drag the element, I often select the text by accident. I want to deselect the text when the element is dragged.
当我拖动元素时，我经常不小心选择了文本。我想在拖动元素时取消选择文本。

Clear document selection document.selection.empty();
清除文档选择 document.selection.empty();
Something like:
就像是：
$('#main').draggable({
cancel: '#main>* *',
start: function(){
// deselect text
document.selection.empty();
}
});

To deselect everything you can use:
要取消选择您可以使用的所有内容：
document.getSelection().removeAllRanges();

jQuery UI now includes .disableSelection(), which you can use to prevent the text inside your elements from being selected. The API documentation on it isn't hugely useful, but: http://api.jqueryui.com/disableSelection/
jQuery UI 现在包含.disableSelection()，您可以使用它来防止元素内的文本被选中。关于它的 API 文档不是很有用，但是：http: //api.jqueryui.com/disableSelection/
As an aside, Eric G's answer proved supremely helpful for me when creating my own "text highlighting" tool - as Lawrence remarked, it won't throw out an error if no text has been selected.
顺便说一句，在创建我自己的“文本突出显示”工具时，Eric G 的回答证明对我非常有帮助 - 正如 Lawrence 所说，如果没有选择任何文本，它不会抛出错误。
