The difference between these two properties is how long the message is displayed. The value of defaultStatus is displayed any time nothing else is going on in a browser window. The status value, on the other hand, is transient and is displayed only for a short period as an event (like a mouse movement) happens.
window.defaultStatus 被所有瀏濟器支持。
window.defaultStatus 指的是默认值,如果设置了
window.defaultStatus = "do people want thick road";
那么,在鼠标指向空白文档区域的时候,会显示这个值,而不是"完成"
window.status 获取的是脚本赋予的临时值。window.defaultStatus 获取的是默认值。
