爲什麼這些有條件的評論告訴我IE8是IE7？

Question

使用的Internet Explorer 8的這個HTML頁面爲什麼：

<p> 
<!--[if IE]> According to the conditional comment this is Internet Explorer<br /><! [endif]--> 
<!--[if IE 5]> According to the conditional comment this is Internet Explorer 5<br /> <![endif]--> 
<!--[if IE 5.0]> According to the conditional comment this is Internet Explorer 5.0<br /> <![endif]--> 
<!--[if IE 5.5]> According to the conditional comment this is Internet Explorer 5.5<br /> <![endif]--> 
<!--[if IE 6]> According to the conditional comment this is Internet Explorer 6<br /> <![endif]--> 
<!--[if IE 7]> According to the conditional comment this is Internet Explorer 7<br /> <![endif]--> 
<!--[if gte IE 5]> According to the conditional comment this is Internet Explorer 5 and up<br /><![endif]--> 
<!--[if lt IE 6]> According to the conditional comment this is Internet Explorer lower than 6<br /> <![endif]--> 
<!--[if lte IE 5.5]> According to the conditional comment this is Internet Explorer lower or equal to 5.5<br /> <![endif]--> 
<!--[if gt IE 6]> According to the conditional comment this is Internet Explorer greater than 6<br /> <![endif]--> 
</p> 

我得到這樣的結果？

According to the conditional comment this is Internet Explorer 
According to the conditional comment this is Internet Explorer 7 
According to the conditional comment this is Internet Explorer 5 and up 
According to the conditional comment this is Internet Explorer greater than 6 

我不應該得到IE8？

謝謝。

Answer 1

出現不正確它

按照條件註釋 這是Internet Explorer 7中

的唯一評論是在兼容模式瀏覽器，因爲這將呈現爲IE7

Answer 2

對於本地文檔，IE8傾向於自動使用IE7兼容模式。在這種情況下，IE8就好像它是IE7一樣（有一些怪癖）。

你在本地測試這個，或者您的瀏覽器目前在IE7兼容模式設置。
