 > [!NOTE]
-> While `returnValue` has been adopted into the DOM standard, it is present primarily to support existing code. You should use {{DOMxRef("Event.preventDefault", "preventDefault()")}}, and {{domxref("Event.defaultPrevented", "defaultPrevented")}} instead of this historical property.

 ## 值
 
-A {{domxref("Boolean")}} value which is `true` if the event has not been canceled; otherwise, if the event has been canceled or the default has been prevented, the value is `false`.
-
-The value returned by `returnValue` is the opposite of the value returned by {{domxref("Event.defaultPrevented", "defaultPrevented")}}.
-
-## 使用说明
+布尔值，如果事件没有被取消，则为 `true`；否则，如果事件已被取消或默认操作已被阻止，则为 `false`。
 
-`returnValue` was introduced into the DOM by Internet Explorer 6, and due to that browser's ubiquity became so commonly used that other browsers eventually implemented it as well. It has been adopted into the DOM specification, primarily to ensure that existing web content continues to function going forward.
-
-New projects should generally avoid using `returnValue`, although they may if they choose to do so.
+`returnValue` 的值与 {{domxref("Event.defaultPrevented", "defaultPrevented")}} 返回的值相反。
