判斷錯誤？
<script?type="text/javascript">
??function?validB(){?
????var?u_agent?=?navigator.userAgent;?
????var?B_name="不是想用的主流瀏覽器!";?
????if(u_agent.indexOf("Firefox")>-1){?
????????B_name="Firefox";?
????}else?if(u_agent.indexOf("Chrome")>-1){?
????????B_name="Chrome";?
????}else?if(u_agent.indexOf("MSIE")>-1&&u_agent.indexOf("Trident")>-1){?
????????B_name="IE(8-10)";??
????}
????????document.write("瀏覽器:"+B_name+"<br>");
????????document.write("u_agent:"+u_agent+"<br>");?
??}?
</script>為什么我用火狐打開卻顯示是 Chorme 呢？
