It's useful if you want to make text unselectable. If, for instance, you want to make drag-and-drop elements with text on, it'd be annoying to the user if the text on the box accidentally would get selected when trying to drag the box.
如果您想让文本不可选择，这会很有用。例如，如果您想制作带有文本的拖放元素，如果在尝试拖动框时意外地选择了框上的文本，那么用户就会很烦。

Caveat emptor: .disableSelection()is actually harmful on some browsers, as it prevents clicking active elements (e.g. textareas) inside the sortable.
警告清空器：.disableSelection()实际上在某些浏览器上是有害的，因为它会阻止单击textareasortable 内的活动元素（例如s）。
- Firefox 33.1 for Mac OS X (Yosemite):
.disableSelection()prevents clicking on embeddedtextarea; doesn't seem to have any effect otherwise (i.e. it is still impossible to select text with the mouse in the sortable if omitted) - Chrome 39.0.2171.71 (64-bit) for Mac OS X:
.disableSelection()seems to have no effect whatsoever.
- Firefox 33.1 for Mac OS X (Yosemite)：
.disableSelection()防止点击内嵌textarea；否则似乎没有任何影响（即如果省略，仍然无法在可排序中使用鼠标选择文本） - 适用于 Mac OS X 的 Chrome 39.0.2171.71（64 位）：
.disableSelection()似乎没有任何影响。

jQuery documentation says to not use it http://api.jqueryui.com/disableselection/
jQuery 文档说不要使用它http://api.jqueryui.com/disableselection/
Also, I found that it made elements with contenteditable="true"no longer editable.
此外，我发现它使元素contenteditable="true"不再可编辑。
